Modern diet science is much more charitable towards carbs than fads of old. New data assures us thatcarbohydrates areessential to a balanced dieteven when weight loss is an immediate objective.

But a new study published by Harvard researchers in the JAMA Internal Medicine Journal found that not all carbs are equal.

The study, which featured more than 35,000 Ameican adults aged 20 and older, found that the quality of a food group impacted longevity significantly more than the presence of a food group in a given regimen. Despite past studies, a low-fat diet isnt indicative of an effect, sustainable diet.

In this study, overall low-carbohydrate-diet and low-fat-diet scores were not associated with total mortality, researchers said. Unhealthy low-carbohydrate-diet and low-fat-diet scores were associated with higher total mortality, whereas healthy low-carbohydrate-diet and low-fat-diet scores were associated with lower total mortality.

These findings suggest that the associations of low-carbohydrate and low-fat diets with mortality may depend on the quality and food sources of macronutrients.

Since the weight loss market is such a lucrative industry and the medias obsession with diets, it has been argued by some that the market makes a point to blur the line between personal objectives and dietary guidelines. If someone needs to lose weight for health reasons or even for cosmetic purposes, there are healthyand expedient ways to do so.

While carbohydrates give us energy, if the energy isnt used after consumption then theyre stored in our muscles and liver for later. Eventually, if unused, the carbohydrates will turn into fat. Low-carb diets, if adhered to correctly, promote weight loss by limiting the number of carbs we need to use before they become stored as fat. This method works for about six months but fails to be a sustainable system in the long term.

Relying on meats for energy at the expense of carbs is linked toa higher risk for cancer and early death.Restricting carbohydrates is the quickest way to drop weight as long as you apply this restriction to a considered timeline.The Dietary Guidelines for Americas recommend that carbohydrates make up between 45% to 65% of your daily calories. Thats about225 grams for women and to 325 grams for men.

Unlike previous studies, the researchers not only took the number of carbs into account but also the source of carbs consumed. This prerequisite provided an important insight into the role balance plays into longevity and dietary guidelines. When accounting for the total number of person-years (297,768), 4,866 total deaths occurred. Researchers said low-carbohydrate-diet and low-fat-diet scores were not associated with total mortality, but a healthy low-carbohydrate diet and a healthy low-fat diet were associated with lower total mortality.

Our findings show clearly that the quality rather than the quantity of macronutrients in our diet has an important impact on our health, said Zhilei Shan, a postdoctoral researcher at Harvards Department of Nutrition, in a press release. The debate on the health consequences of low-fat or low-carbohydrate diets is largely moot unless the food sources of fats or carbohydrates are clearly defined.

The recommended carb intake can be obtained in three different ways: sugars, starches, and fibers. Each has its own set of health benefits. In addition, fruits, vegetables, milk, grains, seeds, and nuts are a good varied placed as well. When it comes to addressing mortality statistics, there are confounding factors to consider. Carbs, for instance, primarily provide our bodies with energy. If fibers are consumed in your daily carb intake, you lower your risk for cardiovascular disease and type-2 diabetes.

One recent study found that people who ate at least five fruits a day lived roughly three-years longer than those who didnt. Earlier this week, a new report about habitually consuming skim milk reversed the aging process by an average of four-and-a-half-years.
