Soya- symbol of a healthy lifestyle!(?)
In recent years, soy has become a leader of a healthy diet.But what, in fact, is its use?And whether soy is good for everyone?
Soy declared miraculous product.Soy beef, milk, tofu, soy nuts and even chocolate have become a symbol of a healthy lifestyle, along with butter, wheat germ, broccoli, and a subscription to a fitness club.Recall the example of the inhabitants of the country of the Rising Sun.As you know, they try soy products, almost no before the mother's milk, but what their enviable health and the longest life expectancy has become a byword.No wonder that there is a desire to follow their example and become adept soy and no longer worry about their health.
Meanwhile, in the scientific world about soy is no agreement.Some scientists attribute the soybean products magical properties to prevent breast cancer, reduce cholesterol levels, to confront senile dementia, to cope with the "scourge of menopause" hot flashes and strengthen bone tissue... Other representatives of the world of science argue that the role of soybean in fighting these troubles is minimal, andsome even believe that soy with its many side effects causing more harm than good.
According to statistics, this terrible disease threatens every eighth woman.If you are in the family had met the sad diagnosis "breast cancer", the more you are at risk.Scientists are constantly working on the search for drugs that can prevent a tragedy, and one of the candidates for such a role was the soybeans.The first argument, which leads its proponents, is: "Japanese women, which traditionally include soy diet, suffer from breast cancer is much rarer than the inhabitant of Europe and American."Neither does it mean that it is soy helps prevent this disease?Debatable.
His replacement estrogen Let's delve into the theory.Communicating with recipes breast cells, estrogens stimulate their division.If you already have a tumor in an early stage, estrogen, clear, spurring growth.Thus, estrogens are cancer activator.Just so the effect of certain anticancer drugs directed at suppressing the activity of estrogen circulating in the female body.Soy contains substances called isoflavones floor, is surprisingly similar to estrogen in their structure.For this reason, they are also able to "borrow" the cell receptors.As a result, these may not join the estrogen molecule.It turns out that isoflavones play the same role as that of drugs, prescription by doctors, but they do not have side effects.
isoflavones, plant compounds that are part of the soybean, in its biochemical structure similar to the female sex hormones estrogen and have a similar effect.However, isoflavones are selectively displaying both estrogenic and antiestrogenic activity depending on the amount contained in your blood estrogen.
Contact cycle in soy isoflavones have an amazing ability to extend the menstrual cycle, and it is very useful for the prevention of breast cancer.The fact that each cycle is accompanied by hormonal "storm."They are accompanied by an injection of blood in a large amount of estrogen, which, as you know, can trigger the growth of tumors.If the menstrual cycle is lengthened, the hormonal "storm" has to worry less.And it also means reducing the risk of breast cancer cases.
Women who take 40 mg of soy isoflavones daily cycle is lengthened by almost 4 days.It would seem, not so much.However, you figure out how to get the win in a decade!According to statistics, the menstrual cycle of European women is on average 21-28 days, that is, in a calendar year is laid 12-14 cycles.And here at the Asian Women's cycle time is 28-32 days, so that during their lifetime they have recruited less cycles.In addition, they have first menstruation comes later, but the menopause occurs earlier.Again, this means that Asian women have fewer cycles than European.If we compare these data with the high statistics of breast cancer in Europe and the lowest in Asia, we get the "iron" argument in favor of soybeans.Lengthening your menstrual cycle, it actually helps to prevent cancer.
What if? Yes, Asian woman, for which soy is a staple, a little sick of breast cancer and other cancers.However, one could argue that, say, soybeans here at all to do with it.Perhaps, in Asian women have some genetic features, saves them from tumors?But here's the American medical data.When doctors undertook to examine the numerous communities of immigrants from Asia, to change their eating habits in the new location, it turned out that the statistics of cancer among Asian women is not much different from the statistics of indigenous Americans.
Catch choose a profession and a little theory.It turns out that the human body produces regularly called stem cells.they "travel" with the blood around the body and may, depending on the needs of the organism to become breast cells, blood, skin, intestinal mucosa, etc.Unfortunately, stem cells have not yet decided on the choice of "profession", are able to be reborn on the cancer type.
So, soy promotes the choice of "profession" of stem cells, so many researchers and consider it a medicine against cancer.Unfortunately, the beneficial effects of soy is hidden fat minus.Isoflavones have a depressing effect on the endocrine system of children.A child from an early age accustomed to soy, there are significantly more likely to thyroid disease, than its peers, grown on the traditional milk.
against Japanese! Curiously, the Japanese scientists do not share the optimism of their European colleagues about the soybean.Safely statistics of breast cancer in Japanese women they relate exclusively to the account of the national healthy food.Japanese women traditionally eat little, and, based on a secret "feminine" cuisine for centuries is rice boiled on the water.Meanwhile, European researchers have indeed show a steady connection between overeating and increased risk of breast cancer.Moreover, in a list of recommendations for the prevention of breast cancer World Health Organization has included an item on the fight against obesity.
Soya against tides
with the inevitable companions of menopause - hot flashes, sweating, mood swings - modern medicine routinely fights hormones.Unfortunately, the reception of hormones can trigger breast cancer, especially in an age when the body's immune capacity significantly weakened.Scientists propose to use instead of hormones soy products.It must be emphasized that taking soy by itself does not allow to get rid of the tides.However, the woman's condition is improving steadily.Moreover, if the tides happen two or three times a day, soy hardly helps.But if a woman suffers from the tides of eight or nine times a day, then soybeans, indeed, will bring relief.
only beneficial properties of soy, which scientists believe one hundred percent, - is its ability to reduce the level of "bad" cholesterol.However, to achieve the desired effect, it is necessary to obtain 25 g of soy protein per day.It contains many 250 g tofu cheese.It is understood that an amount of tofu by no means overcome.Moreover, every day.How to be?Buy soy protein powder.One measuring spoon of the drug can be dissolved in water, juice or low-fat milk.And you can add to morning oatmeal.
researchers found that soy can effectively prevent osteoporosis in women during menopause.Firstly, because soy contains isoflavones, estrogen, and it is precisely because of the lack of estrogen and osteoporosis occurs in women during menopause.And secondly, in soy protein rich in calcium, which is essential bones that they are strong and healthy.
Excess weight is bad.Obese people are not healthy.Even over 3-5 kg already carries the risk of many diseases.Replacing meat and milk, soy products with high lead you to weight loss.The soy lecithin contains - a substance that takes an important part in the lipid metabolism, reduces fat accumulation in the liver and promotes their "burnout".
not so simple
very cautious about soy is necessary for those who have endocrinological diseases: experience shows that daily consumption of 40 mg of isoflavones slow the production of thyroid hormones.This will be enough to feel weak, non-localized pain and suffer from constipation.
Scientists do not exclude that the passion soy products can damage people suffering from urolithiasis.The reason is simple: in soybeans are oxalic acid, oxalate salts, which serve as the starting material for the formation of kidney stones.Due to the high content of soybeans hormone compounds is contraindicated for pregnant women.
Soy is different
In what form is best to consume soy?What to stay - by soya mince whether, milk, cheese, or perhaps take supplements with soy isoflavones?Experts unanimously voted against nutritional supplements.To take isoflavones in "pure" form, you have to be a hundred percent sure that you do not have cancer.Medical diagnostics in this sense, still limping.So it is better not to risk it.In addition, nutritional supplements, you will not be able to obtain valuable soluble fiber, which is rich in natural soy products and which prevents the development of colon cancer.
no secret that soy has a specific taste, which is not so easy to get used to.It is unlikely that you will be able without training to master a glass of soy milk!Therefore, at first try to gradually add soy to your favorite dishes.For example, put a tofu salad or pasta instead of cheese.With soy meat can be cooked spaghetti bolognese or rice pudding.
Nutritionists advise to replace soy frankly harmful products.For example, the crunch soy nuts instead of chips or put on a plate of soy burgers instead of fatty pork pieces (savings of up to 30 grams of fat, and this is serious!).However, do not try to supplant all other soy protein from their diets!In light of the many other good sources of vegetable protein.Remember, the harmful protein does not happen.Harmful is a method of preparing a particular protein meals ...
