Diets high in red and processed meats may increase estrogen in the body. If your diet's currently high in these foods, consider subbing in other protein sources like beans or fish. Maintain moderate body fat levels. Because fat tissue produces estrogen, losing excess body fat could help reduce estrogen levels.
What foods cause high estrogen? Foods that reportedly increase estrogen include flax seeds, soybean products, chocolate, fruit, nuts, chickpeas, and legumes. Before we delve into why these foods are said to increase estrogen, we need to look at two important definitions; phytoestrogens and lignans.
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.
Tomatoes, kiwi, citrus fruits, cantaloupe, peaches, artichokes, bananas, asparagus, corn and cauliflower all boast great levels of vitamin C and they possess the phytoestrogen power you might be looking for to boost your estrogen.
Broccoli, broccoli sprouts, brussels sprouts, kale, cabbage, cauliflower, and bok choy are all known as cruciferous vegetables. These veggies help your liver metabolize estrogen. The plant sterols in avocados help regulate estrogen and progesterone, which can help regulate ovulation.
Exercise regularly. Research suggests that exercise can help to reduce high estrogen levels. Premenopausal women who engage in aerobic exercise for five hours a week or more saw their estrogen levels drop by nearly 19%. Cardio exercise helps the body break estrogen down and flush away any excess.
But citrus fruits may be able to take things a step further. Fruits like oranges, lemons, and grapefruits contain phytochemicals that can act as antiestrogens and target estrogen receptors, preventing the growth of cancer cells.
“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.
Products like eggs or milk contain high estrogen levels because they are produced in parts of the animal's body that regulate its hormones. Eating high estrogen foods can help people who suffer from various conditions related to low estrogen levels.
Since fat tissues release estrogen, increased body fat can lead to high estrogen. Stress also impacts your estrogen levels through cortisol. Cortisol is produced as a response to stress. A high cortisol level limits your body from making enough progesterone to balance estrogen levels.
Medications used as estrogen blockers include: Aromatase inhibitors (AI): This medication can increase testosterone, along with other hormones, by inhibiting the ability of androgens to be converted to estradiol in the body. This decreases the overall level of estrogen in the body.
Body fat: Obesity or excess of body fat can lead to estrogen dominance. These fat tissues store estrogen in the bloodstream, which shoots their levels to cause adverse health issues. Not only this, the fat tissues have the ability to synthesize estrogen from other hormones of the body too.
Estrogen helps protect the heart from disease, potentially by maintaining higher levels of good cholesterol, called high-density lipoprotein (HDL), in your blood. Lower estrogen levels, especially during menopause, can increase your risk of developing heart disease.
Blackberries, blueberries, cranberries, raspberries, and strawberries can all help to increase estrogen levels. As well as being rich sources of fiber, vitamins, and antioxidants, berries contain high levels of phytoestrogen lignans.
A Fred Hutchinson Cancer Research Center study involving postmenopausal, overweight, and obese women who took 2,000 IUs of vitamin D daily for a year found that those whose vitamin D blood levels increased the most had the greatest reductions in blood estrogens, which are a known risk factor for breast cancer.
If your estrogen levels are too high or too low, then magnesium can help bring them back to stable levels, which will positively impact testosterone and progesterone.
Diet-related causes of elevated estrogen levels
Your overall diet can impact your hormone levels. Research shows that Western-type diets high in ultra-processed foods, added sugar, and animal foods (like red meat and eggs) are associated with high estrogen levels.
