High levels of oestrogen may increase a woman's risk for breast cancer, according to the Cornell University Cancer Research Center. Oestrogen is the female sex hormone which occurs naturally in the body but can also be supplemented with foods and wellness pills. A diet high in plant oestrogen, also called phytoestrogen (from the Greek word "phyto" meaning plant), the strongest phytoestrogen foods include flaxseeds, oats, garlic, red clover, black cohosh, and soy, which includes soy milk, tofu, textured vegetable protein, and edamames. When considering a diet low in plant oestrogen, consult with your health care provider; plant oestrogen may also offer protection against health problems associated with menopause, such as hot flushes.
White-flour-based breads, cereal and pastas are low in plant oestrogen. Enriched white-flour products have a low fibre content, fibre which helps a person break down foods and excrete toxins and chemicals into urine. Apart from being low in plant-oestrogen, white flour products also inhibit oestrogen absorption. This means that men or women who have high-oestrogen levels that wish to cut back on oestrogen can choose to have white-flour foods to decrease the amount of oestrogen they take in daily.
Citrus fruits are oestrogen inhibitors and low plant oestrogen foods. Considered a strong anti-oestrogenic food, citrus fruits are low in fibre, like white flour and white rice. Oranges, grapefruit, pineapple, lemons, limes and mandarins are also high-citrus, low oestrogen fruits. Apart from their low plant oestrogen content, citrus fruits supply essential vitamins and minerals.
Unprocessed dairy products, such as organic whole milk, butter, cheeses and ice creams, are low in plant oestrogen. Women and men seeking to increase their oestrogen hormone levels drink soy milk and other soy dairy products because soy, according to the Cornell University Cancer Research Center, is the strongest phytoestrogens, or plant oestrogen, food source. To eat foods that have low plant oestrogen, stick with whole milk dairy products and aged, whole milk cheeses.
