Fontana investigations are not anything like the first attempt to discover a potential relationship between diets low in calories and life expectancy. In fact, traditionally always been associated with longevity thinness, simply statistical issues: the thinner tend to live longer than those entered into meat.
Further experiments with invertebrates first, and then mammals, have shown a genetic pattern that could explain the mysterious relationship between diet and age. Studies published in prestigious journals like Science and Nature have discovered that mice live longer were those who ate fewer calories.
As seen Abelenda Fernanda, “also a recent pilot study has shown that following a low calorie diet would reduce the cell damage by free radical production and therefore slow down the effects of aging on gene expression. It would also have a role protective against cancer, reduce the risk of ischemic heart disease and increase life expectancy. ”
In fact, the rejuvenating effects that are reported to eat with control, in part, a matter of logic. White Canalejo, nutritionist, explains that “balanced intakes, helping the body stay young because the food is better digested and not expose our bodies (heart, liver, kidneys) to greater effort.”
However, scientists are for the time being skeptical. The caloric reduction in humans requires the agency to restrict energy expenditure, which is an important activity loss, obviously, no benefit to health. In a way, what would be gained in years, would be lost in quality of life.
As pointed out by the dietitian, Fernanda Abelenda, “a healthy lifestyle is not one that only consists of a diet low in calories and did not include a balanced physical activity program. And by this we mean that walking 30 minutes and is itself a ‘physical activity program. “The key is to eat the young wide variety of food, without excess, with moderate exercise and stress management.”
