Oestrogen is a key hormone that plays an essential role in reproductive health, bone density, and brain function[1]. While the body produces oestrogen naturally, certain foods can help support healthy hormone levels through the presence of phytoestrogens, plant compounds that act similarly to oestrogen in the body[2].
These compounds have gained attention for their potential to ease symptoms associated with hormonal fluctuations (the natural, temporary, or sometimes drastic shifts in hormone levels within the bloodstream), particularly during menopause[2]. Including foods that contain phytoestrogens may help support hormonal balance and ease menopausal symptoms like hot flashes in some people, though effects can vary and evidence remains mixed[3].
What are Phytoestrogens?
Phytoestrogens are naturally occurring plant compounds that have a chemical structure similar to oestrogen; although found in higher levels in women, they are also present in men in lesser quantities[2].
- Because of this similarity, they can bind to oestrogen receptors in the body and mimic or modulate the hormone's effects, depending on existing hormone levels[2].
- There are several types of phytoestrogens, including isoflavones, lignans, and coumestans, which are found in various plant-based foods such as soy, flaxseeds, lentils, and whole grains[4].
- Though weaker than natural oestrogen, phytoestrogens can interact with oestrogen receptors and may influence hormonal activity. They are often studied for their potential role during menopause[2].
- Research suggests that phytoestrogens may help ease symptoms such as hot flashes and may support bone and heart health in some people[5].
The effects of phytoestrogens can vary from person to person, depending on individual health status, hormone levels, and overall diet.
Top 10 Oestrogen-Rich Foods
Incorporating oestrogen-rich foods into your diet may be a natural way to support hormonal balance and overall well-being[3]. From flaxseeds to soy products, these nutrient-dense foods may help you maintain optimal oestrogen levels and promote various aspects of your health[2]. Here are the top 10 foods high in oestrogens, each offering unique health benefits:
1. Flaxseeds
Flaxseeds are one of the richest sources of lignans, a type of phytoestrogen known for its numerous health benefits. Preliminary evidence suggests that lignans may confer potential benefits for heart health and may be associated with an altered risk of some hormone-related cancers[5]. Additionally, the fibre content in flaxseeds may support digestive health, promoting regular bowel movements and maintaining a healthy gut microbiome[4].
For women going through menopause, flaxseeds are often studied for their potential to ease symptoms like hot flashes, as they contain plant compounds that can interact with oestrogen activity in the body[2]. Incorporating ground flaxseeds into your diet can be a simple yet effective way to support hormonal balance and overall well-being[4].
2. Soy Products
Soy products like tofu, tempeh, and edamame are among the richest sources of isoflavones, a type of phytoestrogen known for its oestrogen-like effects in the body[2].
- Isoflavones such as genistein and daidzein can interact with oestrogen receptors and may influence hormonal activity[2].
- These compounds are often studied for their potential role during menopause, including possible effects on hot flashes and bone health, although responses can vary[5].
- Some studies suggest that regular intake of soy-based foods may be associated with cardiovascular health benefits and a potential link to a lower risk of certain hormone-related cancers, though the evidence is inconclusive. These effects vary by population and the timing of intake[1].
Consult your healthcare provider before making significant dietary changes for hormone management.
Incorporating soy into your diet may offer a natural and plant-based way to support oestrogen levels.
Recipe: Tofu & Edamame Stir-Fry (Vegan)
- Sauté 1 cubed, pressed block of tofu in 1 tbsp sesame oil until golden. Remove.
- In the same pan, cook 1 tsp grated ginger, 2 minced garlic cloves, 1 cup broccoli, and 1 sliced red bell pepper for 3–4 mins.
- Add 1 cup edamame, tofu, 1 tbsp soy sauce, and 2 tsp rice vinegar. Stir-fry 2–3 mins.
- Serve over brown rice or quinoa. Top with sesame seeds, spring onions, or chilli flakes.
3. Sesame Seeds
Sesame seeds are a rich source of lignans, a type of phytoestrogen that may influence hormonal activity in the body. After consumption, lignans are converted by gut bacteria into compounds with mild oestrogen-like effects, which may play a supportive role in oestrogen balance. In addition, sesame seeds provide nutrients such as calcium, magnesium, and healthy fats and are often associated with benefits for heart health and inflammation support[6].
Including sesame seeds in your diet can be an easy and nutritious way to boost phytoestrogen intake[4].
4. Garlic
Garlic, widely known for its medicinal and culinary uses, is not a significant source of phytoestrogens and does not meaningfully contribute to oestrogenic activity in the body. However, it may support hormonal and overall health through its antioxidant and anti-inflammatory properties[4]. Garlic is particularly valued for its potential role in supporting bone health, especially in postmenopausal women, possibly through mechanisms related to reduced oxidative stress rather than direct effects on oestrogen levels[7].
Additionally, garlic is rich in antioxidants and has powerful anti-inflammatory and heart-protective properties. Regular consumption may also help lower cholesterol and support immune function[7]. Incorporating garlic into your meals enhances flavour and offers subtle hormonal and overall health benefits[4].
5. Peaches
Peaches contain small amounts of phytoestrogens, mainly lignans, that may help support healthy oestrogen levels[4].
- These plant compounds can bind to oestrogen receptors and offer mild hormonal effects, making them particularly beneficial for women experiencing hormonal fluctuations[2].
- In addition to their phytoestrogen content, peaches are rich in vitamins A and C, fibre, and antioxidants, supporting immune function and skin health[8].
Adding fresh or dried peaches to your diet can be a sweet and nutritious way to enhance overall well-being[4].
6. Berries
Berries, such as strawberries and blueberries, are delicious as a snack. Although they are minor contributors of phytoestrogens, they contain essential nutrients such as vitamin C, polyphenols, potassium, and manganese[4].
- These tiny fruits contain lignans and flavonols, which are known to weakly modulate oestrogen receptors in the body[2].
- Consuming berries regularly can help support bone health and potentially reduce the risks associated with oestrogen deficiency[5].
- Additionally, the antioxidant and anti-inflammatory properties of berries further enhance their benefits, making them a powerhouse for hormone balance and overall wellness[6].
7. Dried Fruits
Dried fruits such as apricots, dates, and prunes contain lignans, a type of phytoestrogen. Because the dehydration process removes water, these compounds become more concentrated per gram compared to fresh fruit[4]. While dried fruits contribute to overall lignan intake, they are moderate rather than highly concentrated sources when compared with foods like flaxseeds or sesame seeds[4].
While specific studies on dried fruits are less prevalent, their fresh and dried forms are well known for promoting oestrogen-like activity, supporting bone density, and mitigating menopausal symptoms[2]. The high fibre and polyphenol content in these fruits also aid digestion and provide antioxidant protection[6].
8. Tofu
Tofu, a staple in many plant-based diets, is a soy-based product rich in isoflavones, such as genistein and daidzein[2]. These compounds function as phytoestrogens, mimicking the effects of oestrogen in the body. Regular consumption of soy isoflavones may help reduce menopausal hot flashes, improve bone mineral density, and lower the risk of heart disease by modulating lipid profiles[5].
While the relationship between soy consumption and hormone-dependent cancer risk remains nuanced, some studies indicate that tofu may have a protective effect[5]. Beyond its phytoestrogenic properties, tofu is also an excellent source of plant-based protein and is incredibly versatile in cooking, making it a valuable addition to an oestrogen-supportive diet[2].
9. Tempeh
Tempeh is a fermented soy product that is rich in isoflavones, a type of phytoestrogen. These compounds have mild oestrogen-like activity and can bind to oestrogen receptors in the body. In women, tempeh’s isoflavones may help reduce menopausal symptoms and support hormonal balance[9].
They may also contribute to bone health by supporting bone density when natural oestrogen levels decline. In men, moderate soy intake has not been shown to lower testosterone levels and may support heart health by improving cholesterol profiles. Beyond phytoestrogens, tempeh is rich in high-quality plant protein and provides important nutrients, including iron, calcium, magnesium, and B vitamins[9]. The fermentation process enhances digestibility.
10. Nuts and Seeds
Nuts and seeds, including almonds and walnuts, contain modest amounts of phytoestrogens and provide a range of nutrients that support overall hormonal health[4]. Rather than acting as strong oestrogen mimics, the phytoestrogenic compounds in these foods may gently support hormonal balance as part of a nutrient-rich diet, alongside benefits from healthy fats, fibre, and antioxidants[2].
- Almonds, for example, are rich in phytoestrogens that may help alleviate menopause symptoms and support cardiovascular well-being[4].
- Walnuts contain moderate amounts of phytoestrogens, mainly lignans, which have mild oestrogen-like effects in the body. These plant compounds may support heart health, provide antioxidant and anti-inflammatory benefits, and help gently regulate hormones, particularly in postmenopausal women[6].
Incorporating a variety of nuts and seeds into your diet can provide a natural way to support oestrogen levels and promote overall wellness[4].
Benefits of Oestrogen-Rich Foods
