I've heard from a few people that men shouldn't intake soy, but they didn't give any reason to why and when I researched the idea a little on my own, I got mixed opinions on it. Has anyone ever heard this before?
U S Pharmacist said:Although phytoestrogens of one kind or another occur in many different plants, only certain species contain medicinally significant amounts. Among the food plants, legume seeds (beans, peas) and especially soy products are the most prominent sources of isoflavones. Flax seed contains the highest total phytoestrogen content followed by soy bean and tofu. Isoflavones are found in high concentration in soy bean and soy bean products (e.g., tofu), whereas lignans are mainly found in flax seed.
[...] The list of foods that contain phytoestrogens includes soy beans, tofu, tempeh, soy beverages, linseed (flax), sesame seeds, wheat, berries, oats, barley, dried beans, lentils, rice, alfalfa, mung beans, apples, carrots, wheat germ, ricebran, and soy linseed bread.
