Estrogen dominance, high estrogen levels with adverse health effects (especially increased risk of breast cancer), is a serious problem today. Estrogen dominance does not result from increased estrogen levels alone; it is also due to high or low levels of other hormones, environmental factors and medical conditions. The foods that increase estrogen levels and contribute to estrogen dominance are generally unhealthy choices: processed and refined foods, sugary and fatty foods, alcohol and caffeine.
Foods that contain natural estrogen or phytoestrogens may help to reduce estrogen levels in the body, according to Cornell University. These phytoestrogens compete with the body’s estrogen for receptor sites in the body. Low-fat and high-fiber diets also seem to decrease estrogen levels in the body.
Obesity increases estrogen levels in the body, so avoiding exercise and eating unhealthy choices will increase your estrogen levels.
