Studies on the impact of diet on estrogen levels are ongoing. While some research suggests certain foods can influence estrogen levels, it’s crucial to interpret these findings cautiously and consult healthcare professionals for personalized advice. According to a study published in the “Journal of Clinical Endocrinology & Metabolism,” dietary patterns can indeed modulate estrogen metabolism. However, individual responses may vary widely (Davis et al., 2018).
2. Foods That May Increase Estrogen Levels
Some foods are believed to have the potential to elevate estrogen levels due to their phytoestrogen content.
2.1. Flaxseed: A Rich Source of Lignans
Flaxseed stands out as one of the most abundant sources of dietary lignans. Studies, primarily conducted on animals, suggest flaxseed consumption may positively influence hormone levels, potentially reducing breast cancer risk. However, more human clinical trials are necessary to confirm these benefits. A study published in the “Journal of Nutrition” indicated that flaxseed supplementation could alter estrogen metabolism in postmenopausal women (Thompson et al., 2005).
2.2. Soybean Products: A Source of Isoflavones
Soybean products contain isoflavones, often referred to as “plant estrogens.” Consuming soy products can introduce isoflavones into the body, which some believe can influence estrogen levels. However, the estrogenic effects of soy are still debated, and the impact can vary depending on individual circumstances. According to a meta-analysis in “The American Journal of Clinical Nutrition,” soy isoflavones may have modest effects on hormone levels, but more research is needed to understand the long-term implications (Chen et al., 2014).
Plant-based soybean products include:

As a phytoestrogen, chocolate may possess a similar structure to estrogen compounds in the body. A study in the “European Journal of Nutrition” found that cocoa consumption could influence hormone levels in some individuals (Rios et al., 2010).
2.4. Fruits and Vegetables: Packed with Phytoestrogens
Many fruits and vegetables naturally contain phytoestrogens, particularly lignans, which are components of plant cell walls. Dried fruits like apricots, dates, and prunes are also good sources of phytoestrogens. Research published in the “Journal of Agricultural and Food Chemistry” highlighted the diversity of phytoestrogen content in various plant-based foods (Milder et al., 2005).
2.5. Legumes: Rich in Isoflavonoids
Legumes such as beans, lentils, and peanuts contain isoflavonoids, including isoflavones, which interact with estrogen receptors. While some studies suggest isoflavones may impact estrogen levels, more research is needed to draw definitive conclusions. A review in the “Journal of the American College of Nutrition” concluded that the evidence on the estrogenic effects of legumes is inconclusive and warrants further investigation (Messina et al., 2010).
3. Foods That May Decrease Estrogen Levels
Certain foods are believed to have the potential to lower estrogen levels, often through mechanisms related to aromatase inhibition or fiber content.
3.1. Rye Bread: Fiber and Bioactive Compounds
Rye bread contains fiber and bioactive compounds that may reduce estrogen circulation between the digestive system and the liver, potentially lowering estrogen levels in the blood. These bioactive compounds include lignans and alkylresorcinols, which have antioxidant effects. A study in the “British Journal of Nutrition” found that rye consumption could influence hormone levels in women (Andersson et al., 2006).
3.2. Red Wine: Aromatase Inhibitors
Red wine contains aromatase inhibitors, which can reduce the conversion of androgens to estrogen. A study published in the journal “Cancer Epidemiology, Biomarkers & Prevention” suggested that red wine consumption might have anti-estrogenic effects in premenopausal women, while white wine is unlikely to have a significant impact on estrogen levels (Schneider et al., 2008).
3.3. Cruciferous Vegetables: Fiber and Phytochemicals
Cruciferous vegetables are rich in fiber and contain phytochemicals and phytoestrogens, including isoflavones. Consumption of these vegetables may reduce estrogen production in the body. According to a study in the “Journal of the National Cancer Institute,” cruciferous vegetable consumption was associated with lower estrogen levels and a reduced risk of certain cancers (Fowke et al., 2002).
