A diet rich in nuts, peanuts and almonds improves the vitality, the number, the motility and the shape of the spermatozoa. The researchers explain to us why and why this improvement is not directly connected to an increase in the fertility of men. In any case, these foods are good for health.
The sperm of men who regularly eat nuts, peanuts and almonds is better than those that never eat them. The discovery comes from the researchers of the Spanish Human Nutrition Unit of the Universitat Rovira i Virgil in Reus who published the study entitled "Effect of nut consumption on semen quality and functionality in healthy males: a randomized controlled trial". Be careful, however, the improvement of the quality of the sperm does not necessarily influence the fertility of men.
The study. To reach this conclusion, the researchers asked for the participation of 119 people between 18 and 35 who followed a Western diet and divided them into two groups: for 14 days they asked a group to continue with their diet and eat also 60 grams of walnuts, peanuts and almonds, while others have not received any addition to their diet.
A better sperm. From the tests carried out on the sperm of the participants, before and after the experiment, the researchers showed an improvement in the number of spermatozoa, but also of their vitality, motility (how they move) and morphology. Specifically they showed an increase of 16% for the number, 4% for vitality, 6% for motility and 1% for morphology.
Peanuts for fertility? Although these parameters are associated with fertility, the researchers explain that it is not sure that the improvement in sperm in this case actually affects reproductive capacity. However, peanuts, walnuts and almonds are good food for the male diet.
How is it possible? The researchers explain that the benefits of nuts, peanuts and almonds could be related to omega 3, antioxidants and folate present in these foods that have general benefits on our health.
