Did you know that eating about two handfuls of walnuts a day may provide men with the added boost they need to improve their fertility?

“Women are not the only ones who should be paying attention to what they eat when they are trying to get pregnant. This study shows that what men eat is important too.”

Food has been linked to human reproductive success throughout history. And while there’s been much talk about how dietary habits and essential nutrients promote successful reproductive outcomes for women, the habits and nutrients that can improve men’s reproductive fitness have not been devoted as much research. 

A recent groundbreaking study at the UCLA School of Nursing claims to be the first to look at the effects of a plant source of omega-3 on sperm. The 12-week study involved 117 men between the ages of 21 and 35. One group added 75 grams of whole-shelled walnuts to their diet daily. The other group continued their usual diet but avoided eating tree nuts. 

 “We found a significant improvement in sperm parameters in the group that consumed the walnuts,” says lead author of the study, Professor Wendie Robbins. “The men who ate no tree nuts saw no change.”

 Study co-author Catherine Carpenter adds: “Walnuts provide a particularly rich source of a-linolenic acid, a natural plant source of omega-3, which we suspect may have been responsible for the improvements we observed.”
