One study found that green tea consumption was linked to decreased levels of total estrogens. Catechins from green tea could act on aromatase by modulating the expression of CYP19 (aromatase) isoforms. This tea could also act on estrogen receptors and downplay the expression of this hormone.
Green tea's estrogen reduction activity may result from tea polyphenols inhibiting aromatase, the key enzyme converting androgens to estrone or estradiol21.
Interestingly, many studies have affirmed the dynamic effects of green tea in regulating levels of these critical hormones. The antioxidant polyphenols in matcha are reported to elevate FSH and are suggested to promote or lower testosterone accordingly [7-8].
In saying that, research from the U.S. National Institutes of Health that drinking green tea daily could be linked to lower levels of estrogen in post-menopausal women.
Cruciferous vegetables.
Broccoli, cauliflower, kale, collard greens, brussels sprouts, turnips, arugula and all the other wonderful, sulfur-rich foods in this plant family contain 3,3'-diindolymethane (DIM). DIM is chemoprotective, helps reduce high estrogen levels and supports phase 1 of estrogen detox in the liver.
People with heart problems or high blood pressure, kidney problems, liver problems, stomach ulcers, and psychological disorders, particularly anxiety, should not take green tea. Pregnant and breastfeeding women should also avoid green tea.
As shown in Table 3, among premenopausal women in luteal phase, intake of green tea was associated with significantly lower urinary concentrations of total estrogens and estrogen metabolites (P trend = 0.01).
Meanwhile, there's evidence that drinking green tea might help to increase insulin sensitivity and balance the levels of this hormone in our bodies. Green tea may also support weight loss, which can reduce our risk of developing hormone imbalances.
DIM (Diindolylmethane/3,3′-Diindolylmethane) is among the most effective estrogen blockers found in nature. It occurs naturally in cruciferous plants such as broccoli, cauliflower, Brussels sprouts and kale.
1. Red wine. Consuming phytoestrogen-rich foods and drinks like red wine in moderation (up to 5 ounces/148 milliliters a day for women of all ages) has been shown to reduce the risk of cardiovascular disease and breast cancer.
Research shows daily green tea intake increased metabolism excessive estrogen for postmenopausal women, compared to green tea intake of one cup or less per week. This result suggests a daily intake of green tea help to normalize estrogen dominance and to reduce the risk of hormone-related cancer.
Green tea can cause side effects due to caffeine. These can include anxiety, tremors, irritability, and sleeping problems. This is more likely if you're sensitive to caffeine or take large doses. Side effects are less common with green tea than with other drinks that have caffeine.
Studies have indicated that polyphenols found in matcha can help bring down estrogen levels as well as boost progesterone levels.
“Drinking caffeine can increase estrogen levels in women, sometimes leading to an estrogen dominant state,” says Odelia Lewis, MD, a medical contributor to ABC News Medical Unit. “Estrogen dominance is associated with premenstrual syndrome, heavy periods, fibrocystic breasts, and even certain breast cancers.
Drinking green tea in moderate amounts (about 8 cups daily) is likely safe for most people. Green tea extract is possibly safe when taken for up to 2 years or when used as a mouthwash, short-term. Drinking more than 8 cups of green tea daily is possibly unsafe.
Increases premenstrual syndrome: If green tea is consumed in a high amount then it can increase premenstrual syndrome (PMS) in women during periods. An increase in PMS can cause irritation in the body, headache, mood swings, abdominal pain, etc. Therefore consumption of green tea should be restricted up to 2 cups only.
Research shows that avocados can help reduce the absorption of estrogen and boost testosterone levels. They also improve heart health and aid in satiety. We need enough healthy fats to make hormones, and avocados are a great source of hormone building blocks.
Cruciferous Vegetables
Packed within cruciferous veggies are phytochemicals that block the production of estrogen, allowing them to be an effective addition to an anti-estrogen diet. This group of vegetables includes kale, broccoli, cauliflower, Brussels sprouts, and arugula.
