PARIS – Middle-aged people who get about half of their daily calories from carbohydrates live a few years longer than those who follow carbohydrate-rich and low-carbohydrate diets, according to a study published in the Lancet medical journal.
"Our data suggest that a diet based on low-carbohydrate animal products may be associated with a shorter life expectancy and should not be encouraged," says lead researcher, Sara Seidelmann, of Brigham and Women's Hospital in Boston.
These diets question the way of "paleo" diets, a trend in Europe and North America, which avoid carbohydrates in favor of animal proteins and fats.
According to the study, a low-carbohydrate diet is a diet that delivers less than 40% of total energy, although much of this type of diet reduces that ratio by 20% or less.
At the other pool, a percentage equal to or greater than 70% of the energy from carbohydrates (pasta, rice, sugary drinks, candy and others) can also extend the life span, but much less, according to scientists.
