Eating nuts every day can improve the quality of sperm, a study suggests.
A research team at Rovira i Virgili University in Spain analyzed the impact of daily nut intake on the quality of the sperm of 119 healthy men between 18 and 35.
Participants were divided into two groups, one told to eat 60 g of almonds, hazelnuts or walnuts in addition to their normal diet for 14 weeks, and the other group not to.
The group who ate nuts had a 14 percent higher sperm count, four percent higher vitality, six percent higher motility, and one percent better morphology -- the standard criteria for sperm quality used by the World Health Organization.
The nut eaters also significantly reduced the level of sperm DNA fragmentation. The more fragmented sperm DNA is, the higher chance of male infertility.
The researchers said the findings support many existing studies that argue antioxidants such as omega-3 fatty acids, vitamins C and E, selenium, zinc and folic acids all help improve sperm quality. Nuts are rich in these ingredients.
