Find out how walnuts can help men's sperm health and fertility.

A new study shows eating walnuts daily can help improve sperm health.

The study, published in the journal Biology of Reproduction, suggests that eating around 2 handfuls of walnuts a day (75g) can improve sperm health in men. Researchers discovered improvements in sperm shape, movement and vitality in those men that consumed walnuts over 12 weeks. The sperm also showed fewer chromosome abnormalities at the end of the 12 weeks than it did at the start of the study. The study involved 117 men between the ages of 21 and 35, who were divided into two groups. One group added 75 grams of whole-shelled walnuts to their daily diet.

The other group continued their usual diet but avoided tree nuts. Both groups ate a typical Western-style diet.

Walnuts are a rich source of Alpha-Linolenic Acid (ALA), a natural plant source of Omega-3. It is this particular Polyunsaturated Fatty Acid (PUFA) which researchers suspect may be responsible for the improvements. Walnuts also contain vitamin's B-complex and E, and minerals Copper, Zinc and Manganese. They have also been studied for their benefits in heart health and weight management.
