This review suggests caloric restriction may help refresh aging stem cells, mostly based on animal work.
Our stem cells repair tissue, but they slow down as we age. This review looks at how eating less, known as caloric restriction, can refresh tired stem cells in blood, gut, brain, and muscle. Much of the effect runs through a nutrient-sensing pathway called mTOR, the same one that drugs like rapamycin target.
