A new study says this breakfast staple can slow down how fast you age

Japanese researchers found that a daily serving of plain probiotic yogurt, combined with a healthier diet and moderate exercise, slowed biological aging in older men. A new study out of Japan, published in the journal Aging, found that biological aging slowed by 2.2% among a small group of older men who ate plain yogurt every day, in addition to adhering to standard recommendations for a healthier diet and moderate exercise.
