Several studies have associated regular consumption of walnuts With the prevention of cardiovascular diseases, however, it seems that these nuts continue to offer surprises. Thus, a recent research conducted at the University of California in Los Angeles (UCLA) has shown that the quality of sperm also improves by including 75 grams of walnuts in the daily diet, which would help to promote male fertility.
Researchers from that university have carried out a study - whose conclusions have just been published in 'Biology of Reproduction'-, which has revealed the positive effect of nut intake on sperm quality. In the study - in which 117 men between 21 and 35 years old participated - the volunteers were divided into two groups, and 75 grams of walnuts were added to the daily diet of one of these groups, while the rest of the volunteers continued with their usual diet but avoiding eating nuts.
The sperm of men who had eaten walnuts improved in terms of concentration, mobility, vitality, shape and chromosomal characteristics
According to Professor Wendie Robbins, the lead author of the research, they observed that the sperm of men who had eaten walnuts improved in terms of concentration, mobility, vitality, shape and chromosomal characteristics. It also improved its lipid profile confirming the data obtained in previous studies that pointed out the beneficial effect of nut consumption on cardiovascular risk factors. In the men who did not take nuts, on the contrary, no change was seen.
The authors of the work have related the beneficial effects of nuts on sperm health with their high content of alpha-linolenic acid (ALA), omega-3 fatty acids of vegetable origin, whose action could be reinforced by antioxidants and micronutrients that are also present in this dry fruit.
In addition, according to the study, its high level of ALA is associated with a decrease in the incidence of aneuploidy, which consists of an abnormal number of chromosomes that can cause genetic malformations such as Down syndrome. Therefore, researchers believe that the diet of the male not only affects their reproductive capacity, but also can influence the health of the future baby
