Do hangover supplements actually work? – Nutritional Outlook

Posted: April 22, 2023 at 12:24 am

Hangover remedies are as old as hangovers themselves. After a night of too much merriment, the ancient Romans made a habit of consuming raw owl eggs; meanwhile, the 1878 World Exposition in Paris saw the introduction of the prairie oyster. Some swear by staples like fried food, tomato juice, or even more alcohol. The one thing these remedies all share is that none of them are rooted in science.

But now, emerging research has identified a number of science-backed ingredients that actually show evidence of easing the symptoms of a hangover. Here are a few with scientific backing.

Botanical Rehydration Formula Promotes Liver Health

One emerging hangover remedy targets a well-known hangover culprit: dehydration. Alcohol consumption reduces the amount of vasopressin in the body; in turn, this causes the kidneys to excrete more urine, causing fluid loss. This dehydration is responsible for several hangover symptoms, including headaches and fatigue.1

In fact, every standard serving of alcohol causes a net fluid loss of 3.5 fl oz, says Andreea Simo, manager of quality and regulatory for hydration-supplements brand HydraLyte. A 5-fl-oz glass of wine, for instance, causes 8.5 fl oz of fluid loss. Simo explains that HydraLytes formulation uses a precise ratio of water, electrolytes, and glucose to cause rapid rehydration, enabling the body to absorb water as soon as one starts drinking alcohol. HydraLyte also offers HydraLyte Plus Liver Support, which combines rehydration with antioxidants and vitamins that support liver function.

The formula includes botanicals like milk thistle, which is popular for its liver health benefits, Simo says. Milk thistle has been recognized around the world for its beneficial impact on the liver and has been studied extensively in several human clinical trials. HydraLyte Plus Liver Support helps lower oxidative stress and combat free radicals, both of which have been shown to increase with alcohol consumption.

Nutraceutical Gummy Bears Change the Pre-Game Routine

When it comes to hangovers, an ounce of prevention is worth a pound of cure. Sean ONeill, founder of Toast! Supplements, says most hangover remedies fail because consumers take them at the wrong time.

By the time youre hung over, theres nothing that can help you, ONeill says. Not all the hydration and greasy food in the world can save you.

Thats why Toast! Supplements created Before You Drink, a hangover remedy designed to be taken, as the name says, before one drinks. Before You Drink gummies consist of milk thistle, matcha green tea, Opuntia cacti (prickly pear cactus) powder, and L-cysteine, plus a variety of nutrients like zinc, niacin, and thiamine.

Before You Drink is rooted in research conducted by the Alcohol Hangover Research Groups (AHRG) founder Joris Verster, PhD. AHRG was founded to promote research on alcohol-related hangovers.

The AHRG has found that alcohol metabolism and the inflammatory response associated with alcohol consumption appear to be the [cause of hangovers], ONeill explains. Research shows a significant relationship between cytokines and the severity of hangovers. Research has also found that individuals with higher levels of zinc and niacin report less-severe hangovers. Similarly, another study found prickly pear reduced hangover symptoms, seemingly through its anti-inflammatory effects.

Nicotinamide Tablets Break Down Alcohol Byproducts

At least one hangover remedy is targeting alcohol directly with an enzyme-based approach. Sober Rush is a hangover remedy containing 60 mg of reduced beta-nicotinamide adenine dinucleotide (NADH), or nicotinamide, per serving. The product was developed at the UCLA Cancer Center.

The root cause of a hangover is the buildup of acetaldehyde, Sober Rush said in a press release. The enzymes in Sober Rush break down acetaldehyde before it has an opportunity to cause hangover symptoms.

NADH is the first discovery in the world that can be applied to unravel alcohol-induced liver damage, said Sober Rush Founder Yong Wu, MD, PhD, in a press release. By preventing most of the negative effects from alcohol from ever occurring, Sober Rush allows people to experience and enjoy alcohol more positively.

Emerging Hangover Remedies Embrace Science

Gone are the days of old home remedies and folk cures. Whether its by reducing acetaldehyde, calming inflammation, or rapidly rehydrating the body, modern hangover supplements are demonstrating that they are effective because theyre rooted in science.

Common Sense Health: Fish oil is the superhero of supplements – The Independent

Posted: at 12:24 am

You may be forgiven if you are unfamiliar with Aquaman, a superhero who breathes underwater, communicates with sea creatures, and possesses superhuman strength and agility. But revisit past columns if you havent learned that fish are the real superheroes. Why? Because when mere mortals consume fish, their bodies gain extraordinary powers to fight the arch-nemesis of illness.

Studies have repeatedly shown that the omega-3 fatty acids found in fish oil have remarkable health benefits, including reducing the risk of heart disease, improving cognitive function, and reducing inflammation throughout the body.

To gain these benefits, eating enough fatty fish, like salmon and mackerel, isnt easy, especially with high food prices. For a fraction of the cost, fish oil supplements are a no-brainer.

Whats preventing some people from taking this superhero of supplements?

Some people suffer from fish burps. Its what happens when your digestive system lets out a little aquatic airfare, and a pungent reminder of your fish oil supplement.

The prevalence of burping or other gastrointestinal side effects when taking omega-3 fish oil supplements can vary depending on the individual. Some studies report that 30% of individuals may experience gastrointestinal symptoms such as burping, heartburn, or diarrhea. Most people experience no effects at all.

Why do people burp from fish oil? The main reason is that fish oil is a rich source of omega-3 fatty acids, which can be difficult for the body to digest, leading to the release of gas, which causes burping.

For those who are affected by burping, taking fish oil supplements can be a real problem. Not only is the burping unpleasant and embarrassing, but it can dissuade people from taking fish oil altogether, leaving them without the health benefits.

The likelihood of experiencing burping or other gastrointestinal side effects may also depend on the dose and formulation of the supplement being used.

And thats where there is a good solution to the burping problem. Look for a fish oil supplement that offers a form more readily accepted by the stomach. One example to be found at health food stores is Certified Naturals Omega3X fish oil containing MaxSimil, which is pre-digested with enzymes, leading to better absorption and making it much less likely to cause burps.

To explain, omega-3 fatty acids are a type of polyunsaturated fat that are often found in the form of triglycerides. Triglycerides are the main form of fat in the human body and in the food we eat. They consist of a glycerol molecule and three fatty acids. In consuming omega-3 fatty acids, the role of the digestive system is to capture them for use as energy.

But our bodies contain a lot of water, and these oily triglycerides therefore can pass right through the bodys digestive system and out the other end, all benefits missed. The purpose of using enzymes is to convert the fats from a triglyceride to a monoglyceride. Monoglycerides are the form of fat that our body must convert fish oils into, so having it pre-digested into a monoglyceride makes it easier for our system to absorb, and thus less burping.

In another approach to reduce burping, some supplements involve gelcaps that are enteric-coated for delayed release, but these can contain undesirable plasticizers.

For some, no matter how good the supplement, burping can remain a problem. Try refrigerating the capsules and taking them with food. Remember, accepting a little burp is better than forgoing the benefits.

If persistent or severe burping persists, talk to your healthcare provider, as these symptoms may indicate an underlying health condition or allergy.

Dr. W. Gifford-Jones is a graduate of the University of Toronto and the Harvard Medical School. For more than 40 years, he specialized in gynecology, devoting his practice to the formative issues of womens health.

Red yeast rice nutritional supplements health benefits, risks … – Chicago Sun-Times

Posted: at 12:24 am

Red yeast rice, or RYR, is a unique supplement or ingredient created by culturing and fermenting rice with specific strains of yeast.

The fermented product includes bioactive compounds that have a physiological effect and a red color that results from the fermentation process.

RYR has gained attention for its role in cholesterol reduction and cardiovascular disease risk reduction.

When whole, it contains carbohydrates, protein and a small amount of fat as well as pigments, sterols and isoflavones.

The exact composition of RYR depends on the type of rice and yeast. Theres a degree of variability in function and safety.

Several types of bioactive compounds known as monacolins are found in RYR. The most effective of these is monacolin K, which is structurally identical to the statin lovastatin. As with its pharmacological twin, monacolin K inhibits cholesterol production in the liver. But monacolin K from RYR has a wide range of efficacy, which makes its effects less predictable than a statin.

Clinical studies have been conducted on RYRs lipid-lowering effect. A review of 20 clinical trials found that it had an LDL cholesterol-lowering impact similar to low-intensity, low-dose statins such as pravastatin, simvastatin and lovastatin. A reduction of 15% to 25% was reported in subjects of different ethnicities, demonstrating the benefits of this supplement.

Other markers of cardiovascular disease health have been measured, too, including triglycerides, HDL-cholesterol, C-reactive protein, flow-mediated dilation and pulse-wave velocity. All of these improved with RYR supplementation, though the magnitude of improvement varied among studies.

The federal Food and Drug Administration issued warnings in 2007 and 2013 regarding the use of RYR that focused on its safety, effectiveness and a lack of product standardization. Because the efficacy of RYR varies depending on the product, the cholesterol-lowering benefit also varies.

One disadvantage to RYR is the presence of potentially harmful compounds like citrinin, which can harm kidney function and impair fertility. So if youre considering RYR supplements, look for one thats certified as citrinin-free.

Clinical research has settled on effective doses of three to 10 milligrams of monacolin K from RYR per tablet.

RYR and RYR extract are commonly found as dietary supplements. These can be combined with other nutritional and bioactive compounds that aid in cholesterol lowering such as soluble fiber, plant sterols, probiotics and phytochemicals. Talk with your doctor before taking RYR.

The challenge for the food-producing economy in the coming decade will be to produce enough safe and nutritious food for future generations without running out of resources and destroying the earths ecosystems. Although it is estimated that in OECD countries the demand for animal protein sources will decrease by two thirds by 2050, this trend does not apply to emerging economies and lower income countries. To be able to feed the worlds population in the future, it is therefore of the utmost importance to protect the planet and preserve the environment by prudently using its limited resources, producing less greenhouse gas emissions and waste, promoting (or at least stabilising) biodiversity and avoiding deforestation.

These are all strong arguments for promoting the circular economy, which will lead to improved efficiency in resource utilisation. A crucial challenge is the fact that animals performing at high levels need high-quality products that could also be used by humans, which in turn increases competition between feed and food. Indeed, compared to feed, the impact of plant-derived feed additives on feed-to-food competition is negligible, but nevertheless it is good to know that there is one source of additives which does not negatively impact feed-to-food competition while combining other aspects of sustainability: supplements derived from wood. These contribute to sustainable livestock production via improved gut development, allowing better nutrient absorption. Consequently, the animals feed conversion will be improved, and higher production yields will be achieved.

As the most popular wood-derived supplement, lignocellulose, if produced from fresh wood as a by-product of the timber industry, may act as a role model for the circular economy and sustainable use of resources. Lignocellulose is processed wood and contains, depending on the product quality, wood from different species of trees or a combination thereof or even different parts of the tree (trunk and bark). In general lignocellulose is understood to be a source of dietary fibre. Although historically considered as antinutritive ingredient, dietary fibre, when applied in a balanced way, delivers various positive effects in monogastric nutrition, as scientific studies in recent years have shown. Hence, the sceptical view of the inclusion of different fibre sources has gradually been replaced by interest in proper fibre supply and it is now increasingly a focus of animal nutritionists. Today it is generally accepted that a balanced inclusion of fibre contributes directly and indirectly to healthy intestinal functions.

In this context, the most important criterion is the quality of the supplemented fibre. A highly insoluble, but slowly fermentable fibre source will stimulate gut motility and development, allowing for efficient use of feedstuff. These properties are combined in so-called eubiotic lignocellulose. This is derived from fresh wood, is purely insoluble and acts physically, optimising its peristaltic activity. Moreover, it contains a fermentable fraction, which is degraded microbially after passing through the small intestine and entering the caecum and/or hindgut. Within this fermentation process the formation of volatile fatty acids causes lower intestinal pH, providing an unfavourable milieu for pathogenic bacteria and may be directly used by colonocytes as a source of energy, allowing for improved gut development. Consequently, intestinal villi become significantly longer, which improves the intestinal absorptive surface and facilitates the uptake of nutrients and minerals.

An additional value of eubiotic lignocellulose is the presence of wood derived polyphenols as bio-active molecules. Those molecules allow eubiotic lignocellulose to act also as a functional additive, influencing the oxidative status, and elicit gut protective effects.

In addition to the classic lignocellulosic products, a suitable selection of wood sources has made it possible to develop products that can be used in animal nutrition due to their high content of certain bioactive molecules. One of these wood-derived products (agromedROI, agromed Austria GmbH) comprises a bark containing species-specific lignans, which are known to have anti-inflammatory properties. Lignans are natural polyphenols that are found in many plants, where they have protective effects. For the use of wood lignans in animals, anti-inflammatory and antioxidant effects have been scientifically described: they reduce gene expression of various proinflammatory cytokines and bind free radicals and thus reduce lipid peroxidation and diminish the formation of hydroxyl radicals. The combination of those effects attenuates inflammatory processes, which are energy demanding: this can be seen as a cost-saver and, consequently, the saved energy will be channelled into performance, as seen in a scientific trial on aged laying hens in Germany.

Layers in the late laying phase show a decrease in performance and egg quality, which is related to the ageing of oviducts. Age increases oxidative stress, while the efficiency of the antioxidant acting system declines, with close connection to chronic inflammatory responses compared to young layers. The addition of the a wood-derived supplement to laying hens diet at a late phase in their production cycle caused no changes in body weight, while feed efficiency was significantly improved (by 8.5%) compared to birds in the control group (Table 1). Moreover, the inclusion of the wood-derived supplement improved egg numbers and egg mass in a dose-responsive manner. Due to the positive effects of the wood-derived supplement on laying performance, reduced feed intake is not likely to be due to reduced feed acceptance. Improved laying performance and a trend towards higher eggshell stability suggest that wood-derived supplements are part of the solution of prolonging the productive life of laying hens in future and, consequently, this will further contribute to a prudent use of resources.

Feed additives, especially those derived from wood, have a huge potential for reducing the environmental impact of livestock production. Their sustainable production is an almost negligible part of the contribution to resource conservation, but wood-derived additives have the potential to use our limited resources more efficiently.

Could Certain Foods Help With Hot Flashes? – The New York Times

Posted: at 12:24 am

For a phenomenon that affects roughly 75 percent of menopausal American women, hot flashes are still surprisingly mysterious, with little known about how they work or what to do about them.

We dont have exact answers just several theories and questions, said Dr. Arianna Sholes-Douglas, an obstetrician-gynecologist and author of The Menopause Myth: What Your Mother, Doctor and Friends Havent Shared About Life After 35. With the decline in estrogen during the menopause transition, the bodys internal thermostat sometimes registers the body as hotter than it is and sets off rapid sweating and a dilation of blood vessels in an attempt to cool down.

But what triggers that process and why? Its unclear. How are hot flashes connected with other health issues, like cognitive concerns and cardiovascular disease? Also hazy. Treatment options are limited to hormones and just one non-hormonal drug approved by the Food and Drug Administration. All of which, Dr. Sholes-Douglas added, is a clear reflection of the scant attention and little funding devoted to medical research into this phase of a womans life.

In the last two decades, researchers have started to investigate another potential source of relief: diet. The idea stems from studies that have found that hot flashes differ across cultures and might be a largely Western experience. With that in mind, researchers have hypothesized that environmental factors, like diet, might play a part in this difference.

But many of the studies on dietary interventions are small or inconclusive, said Dr. Stephanie Faubion, medical director for the North American Menopause Society and a director of the Mayo Clinic Center for Womens Health. In studies that have suggested certain foods reduce hot flashes, the mechanisms at work are not fully understood, she added.

Still, there is no harm in adjusting your diet to see if it might help manage your hot flashes, Dr. Faubion said.

Soy products, like tofu and soybeans, contain isoflavones, which are chemicals that can bind to estrogen receptors in the body, said Neal Barnard, an adjunct professor of medicine at the George Washington School of Medicine. For that reason, the thinking goes, soy may mimic estrogen. Its one of the most-studied foods in connection to menopausal symptoms, and theres some evidence that eating it might be associated with fewer hot flashes. But its unclear whether thats because of the soy itself or another mechanism.

In a pair of recent studies, Dr. Barnard and his team randomly assigned 84 postmenopausal women who reported moderate to severe hot flashes to either their regular diets or a low-fat vegan diet rich in whole grains, fruits and vegetables, including a daily half-cup of cooked soybeans. Moderate to severe hot flashes decreased by roughly 80 percent in both studies.

The caveat there is that this was essentially two different interventions they were on a whole-food, plant-based diet and they had high soy, said Dr. Faubion. So what part of that was responsible for those results? We have no idea. The women in the study also ended up losing weight, which Dr. Faubion said is noteworthy because some studies have shown a correlation between increased body fat and hot flashes, particularly during certain stages of menopause.

Also of interest to researchers are omega-3 fatty acids. But while some studies have found that taking omega-3 supplements seems to reduce the frequency of hot flashes, others found that they make no difference. Supplements aside, the Mediterranean diet, which is rich in foods containing omega-3s like flaxseeds, walnuts and fatty fish like salmon has been shown in some studies to be associated with fewer hot flashes and other menopause symptoms.

Theres some evidence that a diet high in sugar and fat is associated with worse hot flashes. Beyond that, doctors often suggest avoiding certain foods and drinks that seemingly trigger a hot flash, said Dr. Hoosna Haque, an OB-GYN at Columbia University Irving Medical Center, such as spicy food, caffeine, alcohol and also really high-concentrated sugary foods and highly processed foods.

But, she said, that recommendation is often based just on anecdotal evidence, and its not fully understood why those foods and drinks might trigger a hot flash.

It might just be because they can cause spikes and drops in energy levels, Dr. Haque said. Or because something like caffeine can dilate blood vessels much like hot flashes do and may set off a similar chain of events.

Ultimately, we counsel patients that a balanced, healthy diet may help relieve symptoms, but it isnt a treatment, Dr. Haque said. And healthy diets can also have beneficial effects down the line, when it comes to things like bone health, weight gain and cardiovascular health.

Consumer interest in cognitive, immune health rising – Food Business News

Posted: at 12:24 am

NEW YORK After the COVID-19 pandemic, consumers have realized the importance of taking care of both their cognitive and immune health, and supplements have become a sought-after way to do so, according to a study conducted by Kyowa Hakko.

With the launch of two white papers Evolving Consumer Attitudes About Immunity Support and New Survey Reveals Whats Driving Consumers to Energy Drinks and Supplements Kyowa Hakko found 40% of consumers report taking supplements to support immunity in the past 12 months and of those, more than three-in-four do so as part of their regimen for long-term immune support.

This renewed focus on immune health indicates that consumers are looking for new solutions to ensure theyre feeling and performing their best every day, said Karen Todd, RD, vice president of global brand marketing, Kyowa Hakko USA, Inc. Thats where ingredients like our Immuse postbiotic come into play, those that present a new mechanism of action for immune health and are backed by numerous clinical studies.

The survey also states that among US supplement consumers, four-in-five said it is important to their quality of life to have mental focus, mental energy, and the ability to concentrate.

So many of us experience a number of different stressors throughout our day that are jeopardizing our ability to focus, think clearly, and keep our mental energy up, Ms. Todd said. Consumers want more products that include ingredients that are clinically researched to help us overcome those challenges and improve brain health, like Cognizin citicoline.

In addition to seeking the need for more supplements, nearly one-third of supplement consumers said they feel underserved and unsatisfied with the current market for both immune- and cognitive-boosting drinks.

Our surveys are telling us that beverages are a major white space for product development, as consumers look for more opportunities to get functional ingredients into their bodies through their diets, Ms. Todd said.

In Breath-Holding, Kate and a Croc Are Champions – Discovery Institute

Posted: at 12:24 am

Photo: Kate Winslet, by GabboT, CC BY-SA 2.0 , via Wikimedia Commons.

Recently, theWall Street Journalreported that Kate Winslet, and other actors, for the sake of the newest frontier in blockbuster moviemaking are learning how to hold their breath underwater for several minutes.

Around the same time the websiteScience Dailyhighlighted an article fromCurrent Biologythat expounded on how crocs can go hours without air, thus blowing Miss Winslets impressive feat seven and a quarter minutes holding her breath right out of the water. The article attributes this croc ability to evolution.

But things are not as simple as they look. This is especially true once you understand how life works to survive, and the causal hurdles that would have had to have been surmounted to build life from the ground up.

Thats what my recent book, co-authored with Steve Laufmann,Your Designed Body,accomplishes for the reader. Read the book and youll be prepared to analyze the validity of Darwinism, ask evolutionists better questions, and expect better answers rather than just accepting their just so stories.

As Steve and I demonstrate, with each lesson learned about the complexity of life and survival and the built-in engineering that makes that possible, the explanatory power of Darwinism fades away until all that is left is the narrative gloss.

The fundamental building block for all life is the cell. One of the cells most important needs is energy. The cell, whether it lives and works in Kate or the croc, mostly gets this energy from cellular respiration. Cellular respiration involves the cell, in the presence of oxygen, releasing the energy from within the glucose molecule (while producing carbon dioxide) and storing it as ATP (the cells energy currency). The cell does also have a much less efficient way of getting a lot less energy from glucose, called glycolysis, a process that is anaerobic in that it does not require oxygen.

A one-celled organism, such as an amoeba, is like an island of life. Thats because it can get what it needs from its watery environment, while getting rid of what it doesnt need as well. When it comes to energy, the amoeba gets its glucose and oxygen from its surroundings and releases carbon dioxide.

In contrast, a multi-cellular organism, like Kate or the croc, is like a deep dark continent of life since almost all of its trillions of cells are not near its surroundings. Thats why the organism needs to have a respiratory system to bring in oxygen (and release carbon dioxide), a gastrointestinal system to bring in glucose, and a cardiovascular system to carry these chemicals in the blood to or from all of the cells.

Not having enough oxygen (or for that matter, glucose) for your cells, especially the ones in the brain, which affords consciousness and controls breathing and the cardiovascular system, is a quick path to death. So, understanding how a creature can perform these breath-holding feats, while staying alive, is not an exercise in abstraction.

Physicians and engineers, unlike evolutionary theorists, work in the real world of science. The end point that proves any of their thought or practical experiments to be wrong is death whether its that of the body or of a machine. Thats why understanding why an organism has to have enough oxygen (and anything else it needs to survive) and what happens when it doesnt (death) must be plugged into any theory of life. Without this grounding in real life and death science, evolutionists are just letting their imaginations run wild.

Like every multi-cellular organism, Kate Winslet has a respiratory system through which she can bring in the oxygen her trillions of cells need (and release carbon dioxide). This consists of the nose, mouth, pharynx (throat), larynx (voice box), trachea, bronchi, bronchioles, and millions of alveoli, each surrounded by hundreds of microscopic capillaries where oxygen enters the blood from the lungs and carbon dioxide leaves the blood through the lungs. To complete the picture of the respiratory system, we have to add the chest cavity, consisting of the twelve ribs on either side, the sternum (breastbone) up front, the thoracic vertebrae in the upper back, and the connective tissue that holds them all together in addition to the diaphragm and intercostal muscles.

But thats not all. Experience tells us that our respiratory systems function is under control. When we try to hold our breath, within a few seconds something tells us to breathe. This urge comes from the respiratory center in the brain stem. The respiratory center constantly receives information about the oxygen and carbon dioxide levels in your arterial blood from sensors in the main arteries leading to your brain and from within the brain itself.

Every control system, whether biological or technological, is irreducibly complex in that it must have at least three parts for it to work correctly. Absent any one part, the control system fails, and life is impossible.

The first part is a sensor, like the oxygen and carbon dioxide sensors, to detect what youre trying to control. The second part is an integrator, like the respiratory center, to analyze and interpret the sensory data, decide if everything is OK or if something needs to be done, and then send out instructions to correct the problem. And the third part is an effector, in this case the respiratory system, which when signaled by the respiratory center releases built-up carbon dioxide and brings in a new supply of oxygen.

By hyperventilating beforehand, Kate Winslet maximized her blood level of oxygen and minimized her blood level of carbon dioxide. While holding her breath, as her carbon dioxide level rose and her oxygen level dropped, she would have had to resist the urge to breathe and also deal with symptoms like tingling limbs, impaired vision, feelings of freakout while being at risk of becoming unconscious and drowning. Thats why she always did this under the supervision of a trainer. Do not try this at home or alone!

Besides her respiratory system, putting oxygen into her blood to get it to all the cells in her body, Kate has a cardiovascular system. This consists of the heart with its right and left sides, and the pulmonary and systemic circulations. The right ventricle pumps deoxygenated blood through the pulmonary arteries to the lungs where it enters the capillaries surrounding the alveoli to pick up oxygen and then returns to the left side of the heart through the pulmonary veins. The left ventricle pumps oxygenated blood through the systemic arteries to the capillaries in the tissues. There, the cells get the oxygen (and glucose) they need and download the carbon dioxide. The blood then returns to the right side of the heart through the systemic veins.

One final problem remains, though. It turns out that oxygen doesnt dissolve well in water. Thats why Kate Winslet has hemoglobin thats made in her red blood cells, which are made in her bone marrow. Hemoglobin is a complex molecule, containing iron, that locks onto oxygen when it enters the blood from the lungs and so allows the blood in the body to have enough oxygen-carrying capacity.

With maximum exercise, Kates body needs a 14-fold increase in oxygen consumption compared to when shes at rest. This means that her blood has to have enough red blood cells with enough hemoglobin to carry enough oxygen to meet the metabolic needs of her body, no matter what shes doing. So, that means that her body has to control her hemoglobin.

As noted, every control system needs at least three parts and the one that controls the hemoglobin is no different. Kate has specialized cells in her kidneys that sense her blood level of oxygen and in response, the cell as the integrator sends out a certain amount of a hormone called erythropoietin. Erythropoietin travels in the blood and attaches to specific receptors on immature stem cells in the bone marrow and tells them to develop into red blood cells, which produce hemoglobin. So, if the oxygen level goes down the kidney cells send out more erythropoietin which tells the bone marrow to make more red blood cells which gives the body more hemoglobin.

Given her impressive feat, its safe to say that Kate Winslets respiratory, cardiovascular, and hematological systems were all working at maximum efficiency. But the croc can easily beat her. Now, remember, the croc needs this functional capacity for survival. Hes not worrying about performing well enough to meet the needs of the newest frontier in blockbuster moviemaking. Nor is he trying to impress his friends by showing them how long he can hold his breath underwater while risking death by drowning. No, when the croc grabs the hindquarters of an antelope, he instinctively dives down deep into the water, where he knows he can survive for an hour or two without drowning, but the antelope cant.

Since this involves the respiratory, cardiovascular, and hematological systems, they would seem to be the right places to start in comparing Kate and the croc. But before we do, we have to take into account that Kate is warm-blooded, while the croc is cold-blooded.

This difference means that Kate has to use a lot more energy (oxygen) than the croc to maintain her core temperature, which is between 97oand 99oF. She needs to do this so that all of her organ systems, especially her brain, can work properly. Remember, the croc only has to worry about surviving and reproducing. It would seem that being cold-blooded doesnt bother his self-esteem one bit. However, being warm-blooded allows us to have the biggest brains in the animal kingdom, a fact that affords us numerous abilities, like intelligence, reasoning, creativity, self-reflection, and free will, going far beyond mere survival and reproduction.

In contrast to Kate Winslet, the croc can usually maintain its core temperature, between 82oand 92oF, with little effort simply by making sure it lives in a warm climate. In fact, at rest the croc only uses about 15 percent of the energy that a human does. And when it dives down deeper where the temperature is lower, because it is cold-blooded, it is able to reduce its metabolic rate even further.

So, for a given ambient temperature and level of activity, the croc requires much less oxygen (energy) than a human does to survive. This is so even if the human and the croc have the same amount of oxygen available for use. In fact, it means that as compared with Kate, the croc can get by on the anaerobic process of glycolysis to obtain the limited amount of extra energy it provides because he only needs 15 percent of what Kate needs.

From the start we can see that since the croc uses much less oxygen per minute than does Kate, this would at least partially explain why it is able to hold its breath under water so much longer. But theres more. On Monday well ask, How Does the Crocodile Hold His Breath So Long? Stay tuned.

How the principles of evolution can create lasting global change … – Binghamton

Posted: at 12:24 am

Evolution goes beyond the genetic code and the transformation of physical form, from land-mammal to whale or dinosaur to bird.

At the core of evolutionary science is a triad: variation, selection and replication, explains Binghamton University Distinguished Professor Emeritus of Biological Sciences David Sloan Wilson, the founder of Binghamtons Evolutionary Studies (EvoS) program. You can see this triad at work in culture as well, from economics and business, to engineering and the arts, and the functioning of society at all levels.

Knowing how cultural evolution happens also means we can harness it for the larger good, creating a more just and sustainable world. Thats a topic of Multilevel cultural evolution: From new theory to practical applications, a new article by Wilson recently published in Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences.

Co-authors include Binghamton alumnus Guru Madhavan, MBA 07, PhD 09, senior program director at the National Academy of Engineering; Michele J. Gelfand, professor of organizational behavior and psychology at Stanford University; University of Nevada Psychology Professor Steven C. Hayes, who developed Acceptance and Commitment Therapy (ACT); Paul W.B. Atkins, visiting associate professor of psychology with Australian National Universitys Crawford School of Public Policy and co-founder of the non-profit ProSocial World with Wilson; and microbiologist Rita R. Colwell, former director of the National Science Foundation.

The wide-ranging article explores the three hallmarks of cultural evolution: prosociality, or behavior oriented toward the welfare of others; social control, which enforces prosocial behavior and penalizes those who behave selfishly; and symbolic thought, which relies on a flexible inventory of symbols with shared meaning.

Humans have evolved to live in small, cooperative groups, not as disconnected individuals. To be effective, however, society also requires structure.

Otherwise, strategies that are beneficial on the individual or small-group level become maladaptive: Self-preservation becomes self-dealing, helping friends and family becomes nepotism and cronyism, and patriotism fuels international conflict, for example.

We have to have the global good in mind and everything that we do in some sense has to be coordinated with the good of the whole, Wilson said.

The application of evolutionary concepts to larger human society is not itself new. For example, in 1898, Norwegian-American economist Thorstein Veblen wrote an article called Why is economics not an evolutionary science?

Thats a good question, according to Wilson. Now celebrating its 20th anniversary, Binghamtons EvoS program applies evolutionary principles across the curriculum, crossing disciplinary lines into psychology, anthropology, sociology, economics and political science, even the humanities. It was the nations first when it began two decades ago, although similar programs have since developed at other universities.

The curriculum is highly individualized, which allows students to follow their own path. One highlight is its seminar series, in which prominent scholars discuss diverse topics from an evolutionary perspective, from microbiology to anthropology.

Its rare for a transdisciplinary program such as EvoS to last for 20 years, Wilson points out. Graduates include Justin Garcia, executive director of the Kinsey Institute, as well as professors and researchers at a variety of institutions.

Evolutionary concepts have been misused, however. Take social Darwinism, for example, which is often used to justify competition and harsh social inequities as survival of the fittest, a misunderstanding and misapplication of Darwinian theory. Social engineering also has insidious implications, Wilson noted.

We need to ask: Is there anything about evolutionary theory that is especially dangerous in that regard? Or is it the case that anything that can be used as a tool can also be used as a weapon? Wilson asked. I think its the latter.

These concepts become weapons when they are used as means of control, with little to no input from the people they impact, he explained. When people decide to use evolutionary principles to shape their own actions and goals, however, these principles are largely benign.

Checks and balances are at the core of multilevel cultural evolution to avoid power imbalances, making it the opposite of social Darwinism, which portrayed social inequities as necessary and inevitable. Social Darwinism actually has little to do with Darwin or his theories, Wilson points out; its a stigmatizing term associated with the moral justification for ruthless competition, and probably closer to the principles behind neoclassical economics.

But fields such as economics and business neednt define themselves with the neoclassical greed is good ethos of Milton Freidman. Wilson points to the work of Nobel Prize-winning economist Elinor Ostrom, who proved that groups can self-manage common-pool resources avoiding the proverbial tragedy of the commons if they implement eight core design principles.

Wilson collaborated with Ostrom to show that the core design principles can be generalized, providing a key to successful governance for nearly all forms of cooperative activity.

To begin, you need to have a good, strong sense of identity and purpose; thats the first core design principle, Wilson said.

Other principles involve the equitable distribution of benefits and resources, inclusive decision-making, transparent behavior, and levels of response to helpful and unhelpful behavior, as well as fast and fair conflict resolution, local autonomy and authority, and relationships with other groups.

These principles not only build better workplaces, neighborhoods and nations, they can also heal the mind. As social mammals, our minds interpret social isolation as an emergency situation, the authors note, and social support is key for the treatment of such conditions as anxiety and depression.

The tools used in therapy particularly mindfulness are also applicable on a societal level, encouraging adaptability and cognitive flexibility, which helps individuals recover from adverse life events. Thats true of groups as well, Wilson said.

Creating a more prosocial world grounded in equity and cooperation isnt some unreachable pipe dream.

There are practical applications, said Wilson, who established the nonprofit ProSocial World to plant these ideas outside of academia. Right now, not in some far, distant future, we could be using these ideas to accomplish positive change.

Its important to avoid what Wilson calls the archipelago of knowledge and practice, consisting of many islands with little communication. Otherwise, ideas and solutions may become trapped in separate silos.

In essence, the EvoS speaker series functions that way for students, mingling lectures on bacteria with Neanderthals, morality, the arts and more. Students are exposed to ideas they may not have otherwise encountered, which introduces new paths and possibilities. The same can happen in the larger society, too.

While technological changes can spread from one culture to another over decades or centuries, Wilson hopes to spark societal change more quickly. He draws upon the concept of catalysis in chemistry: Added in small amounts, a catalytic molecule hastens the rate of change, he explains.

As catalytic agents, individuals may inspire changes that would otherwise take decades or not happen at all. And this catalysis can happen in ordinary ways, by leaning into the small-group community mindset that fuels our humanity.

Consider a community garden, for example: Reaching out to different community gardens and sharing knowledge can only benefit everyone involved, Wilson said. And those connections dont need to consist of dull meetings; they can involve social interactions such as parties and potlucks, which bring people together and encourage them to make connections.

Imagine repeating that in every walk of life, in our schools or businesses, on every scale from small groups to cities, he explained.

What is essentialism? And how does it shape attitudes to transgender people and sexual diversity? – Phys.org

Recent debates around transgender people and sexual diversity have been marked by essentialism, a profoundly conservative mindset with deep links to religious and metaphysical dogmatism. It is a stance through which conservative thinkers seek certainty in a world of change and fluidity.

Essentialism comprises three key ideas.

First, there is the idea that nature is divided into discrete kinds of things, which are completely and definitively distinct from each other. For example, there is the view that living things are fundamentally different from non-living things, or that human beings are fundamentally different from other animals.

Second, there is the idea that these differences are eternal and necessary. This sometimes takes the form of the religious doctrine that God created the world and all the things in it in accordance with an unchanging typology. But the idea can also be attributed to Plato, the father of Western philosophy, who postulated eternal and changeless "forms" that worldly things copied and instantiated. If a particular thing is an instance of an eternal metaphysical form, according to this theory, it must have clearly delineated properties.

Third, essentialism suggests that each kind of thing has an "essence," which requires it to maintain its distinctness by acting in a way that is true to its nature. If God created things as clearly distinct from one another, then these distinctions become sacrosanct. Another example is Descartes' view that the essential difference between human beings and animals is that only human beings have rational souls.

Many implications, including ethical ones, have been drawn from such claims. To say of an organism that it has an "animal nature" implies that it falls outside the purview of our moral responsibilities, while the existence of "human nature" implies that a person is subject to various moral norms and prohibitions.

There are strong reasons for rejecting such essentialism. The first of these is Darwinism. It is a commonplace of modern biology that human beings evolved from other life forms. Indeed, all the life forms that inhabit the earth today evolved over eons of time from earlier life forms and from non-organic matter.

Those who reject this scientific consensus for religious or other reasons do so because they want to maintain the links between essentialism and a priori moral principles. This way lies doctrinal and moral dogmatism.

The most obvious implication of Darwin's theory of evolution by natural selection is that natural typesas exemplified in biological speciesare not eternal or changeless realities. Species change all the time. The human species has changed over the large spans of time which are required for natural selection to do its evolutionary work.

It follows that there is no human essence and no changeless typology that marks off human nature from the rest of the animal kingdom or from the world of things more generally.

There are also ideological and ethical reasons for avoiding essentialism. The view that human beings are essentially different from other animals supports the view that humans have a unique moral standing. It used to be argued that because animals do not have souls or minds, it was morally legitimate to use them in any way we pleased. The religious version of this argument is that God created animals to be of use to humans. Add to this the argument that animals do not feel pain (because they do not have minds) and all kinds of cruel practices are legitimated. Peter Singer has labeled these theories "speciesism."

Racism is another example of this way of thinking. The basis of this view is also a form of essentialism: in this case, the view that there is an essential difference between black people and white people.

The scientific challenge to racism is data that shows the differences are genetically very slight. The moral challenge is to argue that they are irrelevant. During periods of slavery, colonialism and imperialism, racism often took the form of empirical claims some people were inherently and necessarily less intelligent than others, or more prone to violence, or were in need of strong discipline, or were "primitive" and in need of civilization. People of mixed race are troubling to racists, because they cross essential boundaries, blurring the difference between "us" and "them."

Nationalism, racism and certain views about class are examples of the inherently oppressive quality of essentialism. Economic and social thinkers (sometimes inspired by misunderstandings of Darwin) used to argue that members of the working classes (sometimes referred to as the "lower orders") were inherently stupid and dissolute, so it was doing them a favor to keep them working in the factories and pits for long hours, because only in that way would they ever be productive.

Never mind that talent is distributed arbitrarily across all socio-economic classes and needs only the opportunity to develop in individuals, no matter what class they belong to. As for nationalism, the view that some people are inherently of less worth than others because of their nationality is not the least important of the many causes of war.

Essentialism also lies at the heart of many sexist practices and forms of life. To cite Aristotle: "The male is by nature superior, and the female inferior; and one rules and the other is ruled; this principle, of necessity, extends to all mankind."

According to such essentialism, certain things are said to have inalienable features and, as a result, have a lower or higher status on an imagined hierarchy. Aristotle grounded his view on biological theories about women and men and their sexual functions that we now know were incorrect, but the key point here is that he attributed a different metaphysical "nature" to each sex.

When biological differences are turned into immutable essences of moral significance, they can be used to justify practices that are oppressive and unjust. It is easier to justify preventing women from taking a full part in public and commercial life if one asserts that it is the nature of women to be housekeepers and mothers.

Essentialism also plays a part in the oppression of sexuality. If one maintains that the essence of the male/female distinction is that it is the basis of procreation, then homosexuality can be proscribed as "unnatural." But there is no essential purpose to sexuality. While procreation is an important outcome of sexual activity, it is not its only function.

Transgender identities show there are no essential links between sexuality, gender and biology. Trans activists deny that apparent biological differences create immutable gendered essences. The claim is not that transwomen are biological men who prefer to dress and act like women; it is that, because biological essence does not determine gender identity, transwomen are women.

This is a claim that a male or female identity is not defined on the basis of any material reality of embodied maleness or femaleness, but on a higher abstracted or psychological plane. While it might be difficult for non-trans people to understand what this plane would be, it is clear that it eschews any essentialist definition of what a woman or a man should be.

When gender differences are turned into immutable essences, one can give them moral significance and use them to justify practices which are oppressive and unjust. Nothing can be more offensive to an essentialist than the blurring of boundaries represented by transgender identification. It is the fixing of empirical differences into the categories of metaphysical essences that does the work of grounding oppressive principles.

Prejudices of all kinds usually take an essentialist form. It will often be found that the standards of human excellence propounded by essentialist theory are the standards held by the propounder of the theory. This is why essentialism is usually oppressive to anyone who is "other" in relation to the essentialist. To an essentialist, difference is pejorative.

By contrast, Jean-Paul Sartre's famous phrase "existence precedes essence" proposes that our self-conscious mode of being is not determined by any essential human nature. The "existentialism" he founded is the opposite of essentialism.

Rather than claiming that our human nature, our socialization, our genetic inheritanceor any other material or historical forcedetermines who we are and what we ought to do, existentialists make the radical claim that it is our subjectivity, our project of self-making, which projects itself into the world and uses those factual and formative elements to forge an identity for itselfan identity of its own choosing.

Unlike essentialism, which seeks to fix human life into the definitions its metaphysical categories bring with them, existentialism reminds us that our initiative and creativity are vital in the living of our lives.

Existentialism is anti-essentialist in relation to human existence. It claims the self is not a fixed entity. Human beings create their own modes of being, their values, and their destinies. And this applies to sexuality. Gender is an existentialist project, rather than a fixed essence.

Depending as it does on ancient metaphysical and religious doctrines, essentialism seeks normative certainty in a fluid world. It suggests that everything should act in accordance with its eternal and necessary nature. It is an inherently conservative stance which ought to be expunged from contemporary ethical and political debates.
