Calorie-Restricted Diets May Prolong Health Span
Scientists want to discover whether calorie-restricted diets have the same impact on humans. Previous trials indicate that certain animals who consume fewer calories have a longer life span. A new study implies that calorie restriction may be beneficial for human health. The research team found an essential protein that may improve health, i.e., prolong a person’s disease-free period.
This new study headed by researchers from Yale University investigated the impact of calorie-restricted diets on humans. As per earlier research that involved animals, it was discovered that those who consumed food with fewer calories might live twice longer than the animals who ate food with an average calorie count. The findings may be instrumental in finding alternatives to prolong healthy living.
Unlike most diets for losing weight, diets restrict the average daily calorie intake in a longer-term perspective. Although certain individuals slim down, losing weight is not the main goal of calorie-restricted diets. The research team aimed to discover the mechanisms responsible for these benefits.
The study involved more than 200 participants, and all of them were healthy and not obese. The research team focused on the impact of calorie-restricted foods on the thymus. This gland generates T cells that are vital in the fight against infections. Older people have a weaker immune system and are more prone to infections because the thymus generates fewer T cells. The researchers discovered that the thymus of the participants who followed a calorie-restricted diet generated more immune cells than the thymus of those whose daily calorie intake was regular.
The researchers found that mice who were fed calorie-restricted foods gained less weight and experienced less inflammation. But most importantly, the functionality of their thymus was improved. There are great chances that the impact of calorie-restricted diets occurred due to a specific gene called PLA2G7.
Scientists warn that restricting calories is not simple, and it does not mean eating less fast food. Furthermore, those who do not possess the knowledge required about this type of diet should not practice it since they may have health problems.
