According to a recent study, middle-aged people who consume about half of their daily calories from foods such as pasta and rice live for a number of years.
The results of the research, published in the medical journal The Lancet p doubts the dietary way carbohydrates occur in favor of animal proteins and fats a trend in Europe and North America.
The defenders of these "Stone Time" diets claim that the rapid change – 10,000 years ago with the beginning of agriculture – to cereals, dairy products and legumes did not allow enough time for the human body to to adapt to these foods with many carbohydrates from carbon.
According to the study a low carbohydrate regimen is a regimen in which they provide less than 40% of the total energy, although many diets of this type reduce that ratio to 2. 0% or less.
At the other pool, a percentage equal to or larger than 70% of the energy from carbohydrates – pasta, rice, sugary drinks – can also extend the life span, but much less, depending on the scientists.
"Diets with low carbohydrates that replace proteins or fats are becoming increasingly popular as a strategy for healthy or weight loss," says lead author, Sara Seidelmann, a researcher at Brigham and Boston Ladies Hospital . Our data suggest, however, that a diet based on low-carbohydrate animal products may be associated with a shorter life expectancy and no incentives . "
Seidelmann and his colleagues analyzed the medical records of approximately 15,500 people aged between 45 and 64 when they started a health survey – between 1987 and 1989 – at four different points in the United States. participants completed detailed questionnaires about their eating habits
of 25 years, more than 6,000 of them had died Men and women who took between 50% and 55% of their calories from carbohydrates lived on average four years longer than those who followed a low carbohydrate diet and one year more than those who had high hydration regimens.
