Too much meat and dairy harms sperm

Scientists in Spain have revealed how meat and dairy foods may be linked to fertility problems. This study found that men who ate the most meat and full-fat dairy products had fewer and slower sperm, while those who ate the most fruit and vegetables had higher quality sperm that swam faster. Lead researcher Professor Jaime Mendiola said “…among the couples with fertility problems coming to the clinics, men with good semen quality ate more vegetables and fruit, which means more vitamins, folic acid and fibre and fewer proteins and fats, than those with poor sperm quality”.
