Eating healthy appears to reduce DNA damage for older men

A healthy diet high in micronutrients appears to turn back the clock when it comes to sperm DNA quality in older men, according to new research led by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory.

Researchers analyzed the sperm of 80 men between the ages of 22 and 80. They found that men over age 44 who consumed the highest levels of vitamin C had 20 percent less sperm DNA damage than men in that same age bracket who consumed the least amount of the vitamin. Similar findings were true for vitamin E, zinc and folate.

Younger men, however, did not get the same advantage. The study found that younger men who consumed high levels of those vitamins did not have improved sperm quality compared with their peers with a less nutrient-rich diet.
