Vegetarians may be at risk for zinc deficiency.
Endocrine disrupting xenoestrogens in fish may be interfering with male fertility.
And before we leave the topic, just as the iron requirements in many women are higher than men because some iron is lost every month in the menstrual flow, the zinc requirements in men are higher than women because some zinc is lost in semen. Because the zinc in plant foods isn’t absorbed as well as the zinc in flesh foods, a study published earlier this year found relatively low blood zinc levels in vegetarians, so anyone eating plant-based diets—men or women—should make sure they eat whole grains, beans, and nuts every day, but some men might just require more than others.
