Scientists say eating less can slow the aging process of cells in the body. The researchers studied mice, not people.
One group was able to eat as much as it wanted. The other animals in the other group are limited to eat. Their diet had 35 percent fewer calories than the first group of mice.
The mice with the diet restrictions(限制) were more energetic and suffered fewer diseases. They were not just living longer, they seemed to stay younger for a longer period of time. When you restrict calories (in mice), there is a direct increase in lifespan - the average age of the animal
But how? The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes (核糖体). Ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down.This, in turn, keeps cells and the entire body functioning well.
Earlier studies have suggested a link between calorie restrictions and slowed agingCalorie restriction as a way to slow aging has not been tested in humans. But the main finding for people is the importance of taking care of our bodies And this may help us make better decisions about what we eat.
