Sunflower and sesame contain high amounts of estrogen, as do legumes, such as red beans, chickpeas, green peas, split peas and black-eyed peas. Flax, commonly found in bread, bagels, muffins and cereals, and often used in cow feed, contains high amounts of estrogen.
Soy is also very high in estrogen, with 100 grams of soy containing approximately 103,920 micrograms of estrogen. Soy is often eaten by vegetarians as an alternative to meat products and is commonly found in veggie burgers and hot dogs.
Exposure to synthetic estrogens used in agriculture chemicals, detergents, cosmetics and plastics is linked to increased cancer risks, sexual dysfunction, obesity and depression, according to AlterNet.
