Eating walnuts improves your sperm

Eating around two handfuls of walnuts a day improves sperm health in young men, a study in the journal Biology of Reproduction suggests.

Sperm shape, movement and vitality improved in men who added walnuts to their diet over 12 weeks.

About one in six couples are infertile, with 40% of these due to a male factor.

This study included 117 men between the ages of 21 and 35. The participants were divided into two groups — one who consumed 2.6 ounces of whole-shelled walnuts along with their daily diet, and the other group who ate a regular diet while avoiding nuts altogether.

The lead author, professor Wendie Robbins from UCLA’s Fielding School of Public Health, said, “We found a significant improvement in sperm parameters in the group that consumed the walnuts. The men who ate no tree nuts saw no change.”
Throughout history, food has been linked with human reproductive success; however most of the emphasis has been on the maternal diet and very little focus has been given to the paternal diet.  According to Dr. Robbins, science is suggesting that a father’s diet not only impacts fertility, but can also influence the health of the child and future generations.  Citing a review of the science in this area, Dr. Robbins commented that, “diet is not just maternal territory anymore.” It appears the nutrition status of fathers can be passed down transgenerationally and affect the health of generations to come.  “Healthy diet and nutrition are essential for reproductive health,” commented registered dietitian and father Milton Stokes.  Based on this research, he would advise his male clients trying to have children to include walnuts in their diet on a daily basis to promote healthy offspring.
