It is important to know! Phytoestrogens in foods Bashny.Net

What is phytoestrogens?First, phytoestrogens are NOT hormones of the plants. Second, phytoestrogens are NOT estrogen (estrogen is a female sex hormones that maintain the sex and some other functions in the female body).

Phytoestrogens are nonsteroidal plant compounds that the human body can act not only as the estrogens, but also as an antiestrogen. For example, unlike real estrogens, they do not stimulate and inhibit the growth of hormone-dependent tumors.

Such a dual effect is caused by the nature of phytoestrogens. These plant substances are able to bind to the same receptors (a particular protein structures on the surface of cells), and estrogen. But the action of phytoestrogens is much weaker (approximately 500-1000 times). Thus, at low levels of estrogens, phytoestrogens bind with unoccupied receptors. And with a high level of estrogen, phytoestrogens compete with real estrogen and, occupying the receptors, exert androgenic effects.

Phytoestrogens are contained in the following products:

• Cereal and legume: soy, wheat, oats, barley, flax, rice, alfalfa, lentils.
• Vegetables and fruits: apples, carrots, pomegranates.
• Drinks: Bourbon, beer.

In many of the above products, phytoestrogens are contained in small quantities. Pogovornega about those products, phytoestrogens is enough to make a significant impact on the human body:

 

The phytoestrogens in soyTo date most is known about the phytoestrogens contained in soy. It is primarily the isoflavones genistein and daidzein. Another soy phytoestrogen — glycitein accumulate in seedlings of soybean. Isoflavones are present in plants mainly as glycosides — compounds with sugars.

In the intestine under the action of intestinal microflora glycosides are hydrolyzed and break down on sugary and non-sugary part of component, the so-called AHL icons (that is, "without sugar"). As it turned out, the glycosides of the isoflavones is almost unable to cause estrogen response of the cells. Estrogenic activity aglycones a little higher. However, the most significant contribution to the estrogenic action of soy makes equal — product of further conversion of daidzein. In structure it most resembles estradiol.

The phytoestrogens in red cloverRed clover contains isoflavones from the group of isoflavones (biochanin-A and hormone-netin) and cholestanol (coumestrol). Red clover, like soy, is widely used to prevent the unpleasant symptoms of menopause. However, unlike soybean, clover is not a food product and relates to medicinal plants. Accordingly, there is no data on its impact on the human body with prolonged and regular use. Experimental data to justify the use of red clover extract instead of real estrogen in hormone replacement therapy also is not enough.

The phytoestrogens in LuzernAlfalfa contains phytoestrogen coumestrol and a small amount of formononetin. Alfalfa, like clover, is a cause of reproductive disorders in sheep. The estrogenic effect of alfalfa extract on humans are still poorly understood.

The phytoestrogens in flaxFlax seeds contain phytoestrogens lignans, which in the human intestine into enterolactone and enterodiol. The biological action of lignans are similar to the isoflavones.

The phytoestrogens in licoriceIn the root of licorice is present the isoflavone glib-ridin. Research conducted on the culture cancer cells, showed that the effect of glabridin depends on its concentration. In low concentrations (10-9-10-6 M) glabridin stimulates the growth of cancer cells. In high concentrations (>15 µm) instead, it suppresses their growth.

The phytoestrogens in red wine grapesDiscovered in red wine phytoestrogen resveratrol (TRANS-3,5,4-tri-hydroxystyrene). Resveratrol has a high antioxidant activity.

Phytoestrogens in hopsThis important ingredient of beer contains phytoestrogen 8-prenylnaringenin. Its activity is very high in women employed in cleaning and processing of hops, a common disorder of the menstrual cycle. In the beer content of phytoestrogens is quite low.

The influence of phytoestrogens on the human bodyPhytoestrogens may have different effects on the body depending on a hormonal background.

Phytoestrogens for women in menopauseAt low levels of estrogen (specifically, estradiol) phytoestrogens act as weak estrogens. this effect is found in the use of phytoestrogens for women in menopause.

Various studies have shown that, in this case, phytoestrogens can have a positive impact:

1.Prevention of cardiovascular diseases: isoflavones regulate fat metabolism, reducing the oxidation of low density lipoprotein and the formation of atherosclerotic plaques. At the same time these substances reduce platelet aggregation, improving blood flow and preventing the development of blood clots.

2.Prevention of osteoporosis: phytoestrogens stimulate absorption of calcium and phosphorus, and decrease their leaching from the bones, which prevents the development of brittle bone.

3.The cure for depression and medication menopause: act like natural female hormones, isoflavones reduce the frequency and intensity of hot flashes, normalize blood pressure, which leads to improved sleep and emotional status of women.

4.Strengthening of immunity: phytoestrogens have antiviral and antimicrobial action that helps protect the body from various infections that weaken the female body. The General health of the body naturally becomes a cause of improving the psycho-emotional state, which in itself is already a good remedy for depression.

5.Antitumor effect: the mechanism of anticancer action of isoflavones is not yet fully understood, but statistical studies have shown that intake of soy and products based on it reduces the incidence of tumors of the breast, colon, skin.

But how can you trust this research? Do phytoestrogens help menopause?

There is another view:

Interestingly, soy is not so much us, how much of the food industry. Many producers made the switch to soy. Some manufacture designed so that they can't create products without additives soy. Another hard to give up soy cheapo and go for more expensive natural products.

The soybean market is very large and monopolized. The main role in it played by several American companies whose activities are hidden from the eyes of the consumer, but well-known manufacturers. And of course, they lobby their interests, including trying to provide products with soy useful. At the beginning it was pretty good at it, and it made a lot of statements about the usefulness of soy with heart disease and some kinds of female cancer.

But now, after further and more serious medical research, these statements begin to crumble like a house of cards. For example, recently influential "American Association for the study of diseases of the heart," withdrew the statement from 2000 that the inclusion in the diet with soy products reduces the risk of heart disease. This was done after careful consideration of all the new research on soy. Not confirmed and other beneficial effects of soy protein reported previously: they have not lowered the pressure, not helped at menopause to women who did not protect them from cancer of the breast and uterus.

Phytoestrogens for breast enhancementThe use of phytoestrogens (in capsules or in combination with various creams) for breast augmentation, to improve the condition of your Breasts after childbirth or to restore lost breast shape after a dramatic weight changes based on the above-described ability of phytoestrogens to act as weak estrogens. But, as we have said,the effect of phytoestrogens depends on the natural hormonal. If the lowered levels of estradiol, phytoestrogens will help. If not — can hurt you. In addition, the effect of phytoestrogens on the breast will end as soon as you perestanete to use products that contain them.

The influence of phytoestrogens on menScientists at Queen's University in Belfast found an Association between consumption of soy products and sperm quality in men. The changes were sometimes so serious that it led to infertility.

— Worst of all, when the hormones are soy affect the developing male fetus or the boy when he reached puberty, says Sheena Lewis, head of reproductive medicine at Queen's University in Belfast. They at this time can adversely affect not only sperm, but also on the formation of sexual organs. For example, leading to this disease such as undescended testes, and possibly in the future, and to their cancer.

The effects of soy really is especially dangerous in those critical periods when the fetus is formed reproductive system, and then when it actively develops in early childhood and adapts to the adult way in adolescents. Because all of these processes are formed under the dictation of sex hormones. And imagine how they will occur if they will not interfere with the phytoestrogens of soy. published
