With the confirmation of its anti-oxygen free radical and anti-aging effects, vitamin E has doubled in value and shined brilliantly in the field of human health care. It has become a big star in the vitamin family, and some people even call that the era of vitamin E has arrived.
Second, the main role of vitamin E
1, promoting the secretion of sex hormones and improving reproductive capacity.
For men of childbearing age, vitamin E can increase the level of androgen in the body, increase the number of sperm and enhance sperm motility. For women of childbearing age, vitamin E can increase the concentration of estrogen in the body and improve fertility. Vitamin E is also of great help to menopausal women.
The results of a study on hundreds of women who have habitual abortion are as follows: 97.5% of women who take vitamin E give birth to healthy babies, while women who don't take vitamin E will still have another abortion.
2, anti-free radical, anti-aging
1960, a research institution found a miracle: normal human cells will age and die after 60-70 generations in vitro, but if vitamin e is added to the culture medium, the miracle will happen, and the cells will age and die after 120- 140 generations. In other words, the life span of human cells has doubled.
1In May, 1996, a report on how vitamin E plays an anti-aging role was published. According to the report, taking a large amount of vitamin E supplements (400 international units per day) can help delay the decline of some protein, which plays a role in cell transfer and metabolism, thus protecting brain tissue and immune system from the damage of oxygen free radicals related to aging.
Some experts also pointed out: Studies have shown that vitamin E can speed up the removal of damaged cells and aging cells, and can delay the aging process to some extent.
3, the patron saint of cardiovascular and cerebrovascular diseases
As a strong antioxidant, vitamin E has shown great power in the prevention and treatment of cardiovascular and cerebrovascular diseases. More evidence is helpful to establish the view that vitamin E can reduce the prevalence of cardiovascular and cerebrovascular diseases, that is, heart disease and stroke, and has a therapeutic effect on it, which can reduce the recurrence rate of heart disease, brain rate and mortality rate.
Coronary artery bypass grafting is often a life-saving measure for patients with coronary heart disease, but coronary artery obstruction after coronary artery bypass grafting is a "heart disease" for such patients. Someone studied 156 middle-aged men aged 40-59 who had undergone bypass surgery. The results show that people who take 100 IU or more vitamin E every day have a slower process of coronary artery re-occlusion than those who take less than 100 IU every day. Some experts think: "People who take vitamin E supplements for a long time are 60% less likely to die of heart disease than those who don't take vitamin E", and some experts lament: "The harm caused by not taking vitamin E is equivalent to the harm of smoking." Even a vitamin E research expert said: "Anyone with a family history of heart disease is stupid if he doesn't take vitamin E supplements every day."
Many experts believe that the amount of vitamin E should reach 400 international units every day, and it should be taken for a long time to have a more obvious effect on preventing and treating cardiovascular and cerebrovascular diseases.
4. Prevention and treatment of Alzheimer's disease
If you take a larger dose of vitamin E, the risk of Alzheimer's disease will be greatly reduced. A study in the United States followed 633 people aged 65 or above. At least four years later, 9 1 person was diagnosed as "possibly suffering from Alzheimer's disease". However, there was a surprising discovery that none of the 27 people who took E200-800 international units of vitamin E every day developed Alzheimer's disease (among them, it was also found that taking only 30 international units of vitamin E every day could reduce the possibility of Alzheimer's disease).
A study of 34/kloc-0 patients with moderate Alzheimer's disease found that at least half of the patients in the vitamin E group had delayed progress, while most of the patients in the placebo control group continued to deteriorate. Researchers believe that the common and ancient vitamin E is comparable to prescription drugs in the treatment of Alzheimer's disease, and it is very safe. Therefore, the American Psychiatric Association recommends vitamin E to individuals diagnosed with Alzheimer's disease.
5. Keep your body immune.
Some European medical data suggest that vitamin E can regulate the decline of immunity caused by aging, and this decline of immunity is likely to cause infectious diseases and infectious diseases in the elderly. Researchers in the Czech Republic and China found that if the elderly living in nursing homes consume 400 international units of vitamin E and 65,438+0,000 mg of vitamin C every day, they will reduce bacterial infections.
6. Enhance the detoxification function of the liver
When vitamin E is sufficient in the body, the liver has the ability to detoxify the following substances:
bleaching agent
Insecticide
change
Other environmental pollution
On the contrary, when vitamin E is insufficient in the body, these substances will damage the liver.
7. Prevention of cataracts and macular degeneration
A series of studies from different angles show that the lack of vitamin A, vitamin C and vitamin E in the elderly often increases the risk of cataract and macular degeneration. For example, carotene (1996 1 1 000 international unit) in Harvard Health Bulletin in October can help reduce the possibility of cataract and macular degeneration. Therefore, some experts believe that in order to reduce the possibility of cataract and macular degeneration, we can insist on taking 10000 international units of vitamin A, 1000 mg of vitamin C and 400 international units of vitamin E every day.
8. Help fight cancer
Some data show that if the content of vitamin E in blood is too low, the possibility of cancer will increase by 50%. Studies have shown that vitamin E, whether absorbed from the diet or added alone, can help reduce the risk of some cancers. Experts who have deep research on vitamin E believe that vitamin E can protect the body from lung cancer, stomach cancer, prostate cancer and colon cancer.
9, assist in the treatment of diabetes
People with low levels of vitamin E in blood are four times more likely to develop type II diabetes than normal people. The study of 944 people by Finnish researchers provides epidemiological evidence for the first time, which proves that vitamin E can make insulin in patients with type II diabetes and elderly patients with heart disease play a more effective role, thus playing a certain therapeutic role.
10, neurological abnormality
Vitamin E plays an important role in maintaining normal nervous function of human body. If you have some diseases such as severe liver disease, chronic pancreatitis, chronic diarrhea, etc. , will lead to indigestion and absorption, leading to vitamin E deficiency, which will cause nerve damage, muscle weakness, unstable pace and other symptoms. If vitamin E is supplemented, these nerve injury symptoms will be improved or slowed down. Therefore, taking vitamin E for people with dyspepsia is an effective measure to prevent and protect nerve damage. Some experts also mentioned that a large dose of vitamin E (more than 400 international units) is also very helpful to treat Parkinson's disease, epilepsy, tardive dyskinesia and other diseases.
1 1，PMS
Some experts mentioned that if women with PMS regularly take 400 international units of vitamin E supplements, the symptoms can be relieved to some extent. It is reported that a very professional gynecologist also takes 600 international units of vitamin E every day to treat his own diseases.
Third, the main food sources of vitamin E
Vitamin e is widely distributed in nature and is generally not easy to lack. Foods rich in vitamin e are: vegetable oil, wheat germ, hard fruit, seeds, beans and other cereals; Eggs, chicken (duck) gizzards and green leafy vegetables contain a certain amount; Meat, fish, animal food, fruits and other vegetables are very few. Because vitamin E is easily destroyed by light, heat and alkali, it loses a lot in food processing. For example, the loss rate of vegetables after cooking is 65%, the loss rate of nuts after baking is 80%, and the loss rate of grains after processing is 80%. Most people don't have the habit of eating fresh raw vegetables and nuts, so it is obviously insufficient to supplement vitamin E intake by eating the above foods. Therefore, it is healthy to supplement a certain amount of natural vitamin E every day.
There are two kinds of vitamin E, synthetic and natural, both of which are effective. However, natural vitamin E is easier to be absorbed than synthetic vitamin E, and its storage time in human tissues is longer, and its effect may be twice that of synthetic vitamin E. Of course, natural vitamin E is more expensive.
Four. Vitamin e supplementation
In the case of normal eating, generally take 100 mg every day. When it exceeds 400 mg per day, vitamin E, like aspirin, has a mild anticoagulant effect. When the daily dose of vitamin E exceeds 3200 international units, it will produce toxic effects, such as headache, diarrhea, hypertension and other symptoms, which is seriously called vitamin E poisoning. Therefore, excessive vitamin E supplementation is very harmful and needs vigilance.
Verb (abbreviation of verb) Vitamin E Use five drugs with caution.
When vitamin E is used together with the following five drugs, it must be carried out under the guidance of a doctor. Don't take it yourself.
● Aspirin
Both vitamin E and aspirin can reduce blood viscosity, so when taking vitamin E and aspirin at the same time, the doctor should adjust the patient's dose according to the specific situation.
● vitamin k
Vitamin E has antagonistic effect on vitamin K, which can inhibit platelet aggregation and reduce blood coagulation. Therefore, please don't take vitamin E before operation or while taking anticoagulant drugs.
● Digitalis
Vitamin E can enhance the cardiotonic effect of digitalis. Patients who use such drugs should use vitamin E with caution to avoid digitalis poisoning.
● Neomycin
Drugs that affect fat absorption, such as neomycin, will affect the absorption of vitamin E, so taking them at the same time may reduce the efficacy of both.
● Estrogen
Long-term high-dose (more than 400mg per day) taking vitamin E, especially combined with estrogen, can induce thrombophlebitis, so we should be vigilant.
