Your food choices can affect both the size of your belt and what goes on below it. Healthy folate and zinc levels may improve semen quality, a study from Iran reveals. The researchers found
that infertile men’s average intake of folate and zinc was significantly lower than that of fertile men, who on average met the Institute of Medicine’s recommendations for each nutrient.
The study authors suspect that these antioxidants protect sperm from damage. To keep your swimmers strong, eat two good sources of zinc and folate daily, says MH US nutrition adviser Alan Aragon, MS. Shellfish, spinach, and baked beans are solid options.
