Efficacy of soybean isoflavones
Prevention of menopausal syndrome in women
Before and after menopause, due to the decline of ovarian function, the level of estrogen in the body is reduced, which leads to the disharmony of functional adjustment of various organs and tissues, and a series of diseases appear. Estrogen supplementation can achieve the purpose of preventing and treating such diseases. The manifestations of female menopause: hot flashes, sweating, chills, chest tightness, palpitations, shortness of breath, dizziness, blood pressure fluctuations, etc. Emotional instability, irritability, excitability or depression, anxiety, insomnia, memory loss, inattention, decreased comprehensive judgment ability, etc.
Prevention and improvement of osteoporosis
Osteoporosis refers to the reduction of bone tissue, which leads to brittle bones and easy fracture. It is common in postmenopausal women and elderly men (due to hormonal changes or insufficient calcium and vitamin D). The incidence of osteoporosis in middle-aged and elderly women is much higher than that in men, mainly due to the decrease of estrogen level, negative balance of bone metabolism and decrease of bone mass after ovarian function decline. Isoflavones can bind to estrogen receptors on bone cells, reduce bone loss, increase calcium absorption and increase bone density.
Prevention of breast cancer
Taking estrogen alone for a long time can increase the incidence of breast cancer and endometrial cancer by 5 to 7 times. The structure of soybean isoflavone is similar to estrogen, so it can bind to female receptors on the cell surface, and activate other anticancer mechanisms at the same time, reducing the risk of endometrial cancer and breast cancer in women due to high estrogen.
cancer prevention
Soybean products contain five known anticancer factors, one of which is phytoestrogen (isoflavone), which is a unique anticancer factor in soybean food. Scientists have concluded that the anti-oxidation and anti-proliferation effects of genistein are the main reasons for its anti-cancer effect. Soybean isoflavone has obvious therapeutic effect on breast cancer, colon cancer, lung cancer, prostate cancer, skin cancer and leukemia, and can also prevent ovarian cancer, colon cancer, gastric cancer and prostate cancer. A large number of studies have found that soybean isoflavones can transform cancer cells into cells with normal functions, and at the same time, they can inhibit the bad mass structure and prevent tumor proliferation and cancer cell proliferation.
Prevention of cardiovascular diseases
Heart disease is also an estrogen-related disease. As a phytoestrogen, soybean isoflavone can reduce blood lipid and prevent heart disease by promoting thyroid hormone secretion and bile excretion. It has been fully proved that low-density lipoprotein cholesterol can be lowered without lowering high-density lipoprotein cholesterol. Isoflavones, as the characteristics of flavonoids, have important biological antioxidant effects. Because the oxidation of low density lipoprotein (LDL) cholesterol is a key factor in the process of arteriosclerosis. Women who take 80 mg genistein every day can increase arterial elasticity by about 26%.
Prevention of Alzheimer's disease
Alzheimer's disease (AD) is the most common dementia at present, especially in women. Recent studies have shown that the human brain also belongs to the target tissue of estrogen, and the hippocampal synaptosomes with memory function in the brain contain estrogen receptors. The medical community has confirmed that estrogen levels are closely related to Alzheimer's disease, and taking soy isoflavones and real estrogen is good for the brain.
Beauty and anti-aging effects
The estrogen-like effect of soybean isoflavone can make women's skin smooth, delicate, tender and elastic, and glow with youthful elegance. Women activate the adipose tissue in the breast by supplementing estrogen, so that the free fat is directionally attracted to the breast, thus achieving the effect of breast augmentation. Studies show that modern women have the phenomenon of early menopause, and long-term supplementation of soybean isoflavones can maintain the normal level of estrogen in the body, postpone menopause and achieve the effect of delaying aging.
Improve menstrual discomfort
Menstrual discomfort is generally related to the imbalance of estrogen secretion. Long-term supplementation of soybean isoflavones can maintain the normal level of estrogen in the body and achieve the purpose of improving menstrual discomfort.
Improve the quality of sexual life
The estrogen-like effect of soybean isoflavone can increase the maturity of female vaginal epithelial cells and enhance the elasticity of vaginal muscles, thus improving the quality of sexual life.
Eight effects of lecithin
niniyixue.blog.bokee.net
Lecithin, together with protein and vitamins, is called "three major nutrients". But few people really know about lecithin, and lecithin is only a "noble food" enjoyed by a few people in China. Lecithin has become a very popular nutritious food in developed countries. It is said that Americans even use lecithin for cooking now; The cooked rice is full of grains, crystal clear and fragrant. So, what health functions does lecithin have?
First, protect liver function.
Choline in phospholipids has affinity for fat. If choline is insufficient in the body, it will affect fat metabolism, leading to fat accumulation in the liver, fatty liver and even cirrhosis. Lecithin can not only prevent fatty liver, but also promote liver cell regeneration. At the same time, phospholipids can reduce the content of serum cholesterol, prevent liver cirrhosis and contribute to the recovery of liver function.
Second, the nutrition of diabetic patients
Lack of lecithin will make the pancreas function decline, unable to secrete enough insulin, unable to effectively transport blood glucose to cells, which is one of the basic causes of diabetes. If you eat more than 20 grams of lecithin every day, the recovery of diabetes is quite remarkable. Many patients no longer even need insulin injections. Especially for patients with complications such as diabetic gangrene and arteriosclerosis.
Third, keep blood vessels unobstructed.
Lecithin has the function of emulsifying and decomposing oil, which can improve blood circulation, improve blood lipid, remove peroxides, reduce the contents of cholesterol and neutral fat in blood, reduce the residence time of fat on the inner wall of blood vessels, promote the dissipation of atherosclerotic plaques, prevent intimal injury caused by cholesterol and keep blood circulation smooth. Taking lecithin has a significant effect on hyperlipidemia and hypercholesterolemia, so it can prevent and treat arteriosclerosis.
Fourth, promote the development of fetal and infant nervous system.
Under normal circumstances, pregnant women's amniotic fluid contains a lot of lecithin. There are about 654.38+0.5 billion brain cells in the human body, 70% of which have been formed as early as the mother. In order to promote the healthy development of fetal brain cells, it is very important for pregnant women to supplement enough lecithin. Infant is the most critical period for the formation and development of the brain. Lecithin can promote the growth and development of brain nervous system and brain volume. Therefore, the US Food and Drug Administration (FDA) stipulates that lecithin must be added to infant milk powder.
Fifth, the beauty effect
There are many toxins in normal people, especially in the intestines. When the content of these toxins is too high, they will flow with the blood.
Circularly deposited on the skin, thus forming spots or acne. Lecithin is just a natural antidote. It can decompose excess toxins in the body and excrete them through the treatment of liver and kidney. When the toxins in the body are reduced to a certain concentration, the spots and acne on the face will gradually disappear. Lecithin also has a certain hydrophilicity and can increase hemoglobin. If a certain amount of lecithin is ingested every day, it can provide sufficient moisture and oxygen for the skin, making the skin smooth and moist.
Prevention of intransitive verb Alzheimer's disease
As people get older, their memory will decline, and the real reason is related to the lack of acetylcholine content. Ethylcholine is an important transmitter of information transmission in nervous system. The human brain can directly absorb phospholipids and choline from the blood and quickly convert them into acetylcholine. Long-term supplementation of lecithin can maintain the content of acetylcholine in human body, thus slowing down the process of memory decline and preventing or delaying the occurrence of Alzheimer's disease.
Seven, prevention and treatment of gallstones.
Excessive cholesterol in the body will precipitate, thus forming gallstones, which are 90% composed of cholesterol. The main component of bile is lecithin, in addition to water, cholesterol, minerals and pigments. Lecithin can decompose, digest and absorb excess cholesterol, thus keeping cholesterol in bile liquid. If you take a certain amount of lecithin every day, you can effectively prevent the formation of gallstones, and you can also play a role in resolving the gallstones that have already formed.
Eight, adjust emotions and relieve psychological pressure.
With the increasingly fierce social competition, people often have symptoms such as anxiety, impatience, irritability, insomnia, tinnitus, etc., that is, autonomic nerve dysfunction, which is often called neurasthenia. Regular supplementation of lecithin can make the brain nerves get nutritional supplements in time, maintain a healthy working state, help eliminate fatigue, activate brain cells, and improve symptoms such as impatience, irritability and insomnia caused by nervous tension.
