Phytoestrogens Is there really anything to be afraid of?
Table of Contents
1. What are phytoestrogens?
Phytoestrogens are a group of naturally occurring plant compounds that, due to their chemical structure and biological action, are similar to estrogen, or female sex hormones produced by animal organisms, including humans. They can interact with the human body by binding to estrogen receptors, which allows them to mimic natural estrogens or modulate their action (M. C. Canivenc-Lavier, C. Bennetau-Pelissero 2023).2. It's the phytoestrogens
Phytoestrogens can be divided into 3 main groups which differ in origin and chemical structure.3. Insulated and coated
Some of the most well-known phytoestrogens, mainly due to their abundance in soybeans and soy products, such as tofu, tempeh, and soybean drinks, are supplied with genistein, daidein, and glycine, which are less common than other isoflavones, but can be found in some plants, like cinnamon.4. Other, of a thickness of not more than 10 mm
They're found in flaxseeds, whole grain cereals, vegetables and fruits, and when consumed, they're converted by the gut microbiome into estrogen-like compounds.5. Manufacture from materials of any heading, except that of iron or non-alloy steel, not further worked than hot-rolled, hot-drawn or extruded
The most popular is resveratrol, which is found primarily in the skins of grapes, berries and red wines. Although its biological activity is lower than other phytoestrogens, it still shows the ability to bind to estrogen receptors (M. C. Canivenc-Lavier, C. Bennetau-Pelissero 2023).6. Sources of phytoestrogens
Phytoestrogens are found in many products of plant origin, notably: soybeans and their preparations: tofu, tempeh, soy sauce, soybean drink; nuts and seeds: primarily flaxseeds, but also sunflower seeds and groundnuts;7. Beneficial effects of phytoestrogens on health
Phytoestrogens have complex effects on human health, and their effects can be both beneficial and unwanted, depending on individual factors such as age, gender, health status, but also the way you consume them and the amount you take.8. Relieving the symptoms of menopause
Menopause is a natural stage in a woman's life that is often associated with symptoms caused by decreased estrogen levels (hot flashes or night sweats). In this situation, isoflavones, due to their similarity to estrogen, can be a valuable support. They are able to bind to estrogen receptors, which allows them to gently enhance estrogen action when their levels naturally decrease.9. The impact on the hydrocarbon economy
Phytoestrogens can have a beneficial effect on the carbohydrate economy, which is crucial for the effective management of diabetes and insulin resistance. By enhancing the sensitivity of cells to insulin, these plant compounds help regulate blood glucose levels, especially after eating high-carb foods. Their antioxidant properties can also protect against oxidative stress, which prevents diabetic lesions such as damage to blood vessels and nerves.10. Improving cardiovascular health
Good cardiovascular fitness is the foundation of overall health, and phytoestrogens play an important role in optimizing it. These natural plant compounds effectively lower LDL cholesterol levels, thereby minimizing the risk of stroke and heart attacks. They bind to estrogen receptors, thus positively affecting lipid metabolism and increasing the flexibility of blood vessels. Additionally, by stimulating the production of nitric oxide, they expand vessels, which increases blood flow and improves the functioning of the cardiothoracic system.11. Reduced risk of osteoporosis
Osteoporosis, a disease characterized by reduced bone density, mainly affects postmenopausal women, when a natural reduction in estrogen levels leads to an accelerated loss of bone mass. In this context, phytoestrogens such as isoflavones and lignans play an important role in the prevention of osteoporosis. By their ability to bind to estrogen receptors in bone tissue, they mimic the action of estrogen and help maintain bone mineral density. They also affect the activity of osteoblasts and osteoclasts cells responsible for the proper formation and breakdown of bone.12. Reducing the risk of certain cancers
Phytoestrogens may reduce the risk of cancers, especially those that depend on hormones, such as breast, prostate, or ovary. Research suggests that these compounds may act as protective, competing with stronger estrogens for binding sites on estrogen receptors, thereby limiting the stimulation of cancer cells. Additionally, there are reports that they may also support cancer therapy and improve treatment outcomes (I. J., Rowe, R. J. Baber 2021).13. Improving the condition of the skin
Phytoestrogens also have a significant effect on the health and appearance of the skin, improving its moisture and increasing flexibility by stimulating collagen production. With their antioxidant properties, they protect the skin from the negative effects of UV rays, which contributes to delaying aging processes and reducing wrinkles. They can also regulate sebum production, which is beneficial for people struggling with acne and other skin problems (E. D. Lephart, F. Naftolin 2021).14. Worries about phytoestrogen intake
Phytoestrogens, while offering many potential health benefits, may also be associated with some risk and cause doubt, especially when consumed in large quantities. There is concern, mainly among men, that an excess of phytoestrogen can affect the hormonal economy, lead to adverse changes and, as a result, to so-called feminization. However, it has not been observed that typical intake of phytogen from natural sources has such effects as well (K. E. Reed et al. 2021).15. Summary
The available scientific evidence suggests that the consumption of phytoestrogens from natural plant sources is safe and may have health benefits for most people. Therefore, it is advisable to regularly include products rich in these substances in the diet. However, if you are considering supplementing with phyto Estrogens in synthetic form, you should consult a doctor or a dietitian. This will help to avoid the risk of excessive consumption and the potential side effects associated with it.
