1 Go easy on processed food. Processed and fast foods are both known to be detrimental to health. In the Rochester young mens study carried out at university of Rochester , one group was fed a diet high in processed meat, red meat, refined grain, fast foods, high energy drinks and fast food. Another group of men were put on a healthy diet of chicken, fish fruits, vegetables, whole grains and legumes. Guess what they dicovered? As always the group on the healthy or "prudent" diet had better sperm motility. Other than this, there are numerous studies across the world which have highlighted the positive role of a diet high in whole grains, legumes, fruits vegetables and healthy fats on sperm and fertility.
