<< Do you actually know of any cases of people becoming infertile by eating >>100% raw vegan? Or are you just spouting off? Just spouting off!!!! ;) I'm very fertile when it comes to spouting theories ;) Vicki, that's great for your friend!! How long has he been raw? I think as I said, it's a theory. I love to have my theories get destroyed! Anyway, I would think that any diet that caused nutritional deficiencies might cause infertility, no? For example, from what I've read, there are many minerals that are supposedly necessary for proper sperm production - chromium, zinc, magnesium, copper, potassium, selenium as well as amino acids, such as arginine. Now, from what I understand zinc is a common deficiency problem on raw vegan or fruit diets, or actually, a common deficiency in general! I showed common signs of zinc deficiency after a year on my diet - no wound healing, almost non-existent sex drive. Of course I don't know if I was actually deficient, but I was craving pumpkin seeds like crazy and made myself sick eating them (pumpkin seeds are high in zinc). Ultimately, it's a mystery. However, I will quote from Kirchmann's nutrition almanac: "Even marginal deficiency of zinc will promote decreased sexual interest, low sperm count, and impotence." Now, as one leaves behind grains, meats, dairy, fish, and eggs which are common sources of zinc, one might develop a zinc deficiency over-time as they may not eat enough seeds, or they may not digest those seeds well enough in order to get enough zinc. As I said, it's theoretical, but I see increased risk on diets that don't normally contain zinc. Along with zinc deficiency, appears to come infertility. It does seem to be common knowledge that vegans and fruitarians experience lower sex drives, right? Sometimes I wonder if people eat that way in order to control their sex drive!! Who knows? Some people might, some people might not. I've certainly eaten certain ways to control all sorts of behavior and emotional states! So, as always, I'm not saying my theory is right, I'm not saying it's wrong, but I just see a pattern of dietary restriction that begins when humans adopt agriculture and ends when humans become breatharians. I hope I'm wrong! Thanks for responding, Aaron
