Natural vitamin E can effectively improve human endurance, enhance immune function, and has obvious anti-aging and anti-cancer effects. Can reduce cholesterol and improve human microcirculation; Can effectively prevent cardiovascular and cerebrovascular diseases. Natural vitamin E is also the best choice for beauty and skin care. It has the function of scavenging oxygen free radicals in human body, preventing the generation of physiological spots, and playing a good role in repairing skin burned by ultraviolet rays. Easily absorbed by skin, can promote skin metabolism and improve skin elasticity.
First, regulate blood lipids.
Atherosclerosis is the main cause of angina pectoris, myocardial infarction, hypertension and stroke. The "culprit" of arteriosclerosis is bad cholesterol in blood, which will adhere to the inner wall of blood vessels, leading to aging and hardening of blood vessels. Moreover, the cell membrane lipids produced by the blood vessel wall, once combined with active oxygen in the human body, will produce lipid peroxides, and bad cholesterol will find a "hotbed" on the blood vessel wall, thus forming atherosclerosis and thrombosis.
In order to prevent blood vessels from producing lipid peroxide, the most effective is natural vitamin E, because natural vitamin E has a particularly strong antioxidant capacity, preventing malignant cholesterol from adhering to the blood vessel wall and keeping the blood vessel clean.
1In May, 1993, the British New England Journal of Medicine reported an 8-year survey of more than 87,000 female hospital nurses and 40,000 healthy male professionals. The survey results show that people who take 100 mg (or more) of vitamin E every day for two consecutive years have a 40% lower incidence of heart disease than those who only take vitamin E from food.
Researchers sponsored by the American Heart Association also found that long-term use of 100 mg of vitamin E can reduce the chance of oxidation of low-density lipoprotein (also known as bad cholesterol) by 30%.
Researchers at the Atherosclerosis Laboratory of the University of Mississippi in the United States made such an experiment. They took 100IU of vitamin e every day for three years. Therefore, the process of arterial embolism in monkeys eating high-fat food was delayed or reversed. The incidence of arterial embolism is only 1/5 of those monkeys who don't receive vitamin E. What's more surprising is that those monkeys who have already suffered from arterial diseases have cleared 60% of the arterial platelet accumulation in monkeys by taking vitamin E. In two years, the proportion of arterial embolism has dropped from an average of 35% to 15%.
Vitamin E can also effectively prevent cardiovascular and cerebrovascular diseases. Hodis of the University of Southern California School of Medicine also showed quite good results. They surveyed 40,000 middle-aged men and found that those who took 100IU vitamin E every day for more than two years had a 37% lower risk of major cardiovascular diseases, including heart failure.
The study of patients undergoing coronary artery bypass surgery by Minnesota Clinical Center in the United States found that patients who took 200 mg of vitamin E every day before operation not only had normal blood vitamin E content, but also reduced blood free radical content, while patients who did not take vitamin E did the opposite.
Experts from Harvard University in the United States, Stanford, M.D. and Dr. Rem of Natural Science, stressed that it is difficult for you to get enough vitamin E from food to cope with heart disease, so you need to take vitamin E, and these two experts did it themselves.
Second, delay aging.
Scientific research shows that people's life span should be around 130- 150 years old, but it is difficult to find people with such a long life.
Although aging is an irresistible natural law, it is entirely possible to slow down the aging process and prolong human life through reasonable nutrition. There are many theories or hypotheses about the causes of aging, and the free radical theory is the most important one. Free radicals are atoms, groups, molecules or ions containing valence electrons, which are produced during metabolism or under the radiation of light, heat and high-energy rays. Because the chemical activity of free radicals is high and unstable, it is easy to have a chain reaction with other substances, resulting in new free radicals, which will cause damage to protein, lipids, sugars, genetic materials and nucleic acids in the body. This will aggravate the damage over time, which may cause cell aging and damage, and even cause various diseases. Scavenging free radicals is the simplest and most effective means to maintain normal operation and delay aging.
Vitamin E is a strong antioxidant, which can interrupt the chain reaction of free radicals, protect the stability of cell membrane and prevent lipid peroxidation on the membrane. When people reach old age, brown spots appear on the body surface, which is called longevity spots or senile spots. This is lipofuscin produced by unsaturated fatty acids and fatty acids on cell membrane under the action of free radicals. Not only on the body surface, but also in the heart muscle, liver, especially in brain cells, it accumulates more and more with age, which can cause neurological function, memory and intelligence disorders in the elderly, and even Parkinson's disease. Vitamin E can also inhibit the deposition of lipofuscin in human body and play a role in delaying cell aging.
It is also reported that vitamin E can delay aging by maintaining the stability of genetic material, preventing the variation of chromosome structure and orderly regulating the metabolic activities of the body. Many experiments show that vitamin E can prolong cell life or delay cell aging. For example, human fetal fibroblasts generally die after 65 generations of culture, but adding vitamin E to the culture medium in advance can divide 100 times or more. Human cells cultured in 10% oxygen can delay the aging process and prolong their life span by 20%-40% after adding vitamin E.
Third, beauty and skin care
Vitamin E and skin care: Human skin consists of squamous epithelium and connective tissue, among which chondroitin sulfate, hyaluronic acid and collagen fiber are the main components of connective tissue. Hyaluronic acid absorbs a lot of water in young people, so the skin is elastic, delicate, full and wrinkle-free. With the passage of time, the first manifestation of human aging begins with connective tissue. Various factors weaken the synthesis of chondroitin sulfate and the water absorption capacity of transparent fatty acids, and the skin elasticity is also decreasing day by day.
Vitamin E can maintain the elasticity of connective tissue and promote blood circulation of blood vessels. In the body, it can also regulate the normal secretion of hormones, control the consumption of acid in the body, protect the skin mucosa and other functions, and make the skin moist, fit and full of youthful vitality.
Vitamin E and Beauty: Vitamin E plays an important role in maintaining skin metabolism and preventing skin aging. Vitamin E can prevent the dark brown spots on the face, that is, the accumulation of lipofuscin, promote the blood circulation of peripheral blood vessels, and make the skin rich in nutrition and keep shiny and moist.
Vitamin E and hair: Vitamin E can improve the microcirculation of hair follicles, ensure adequate nutrition supply of hair follicles and regenerate hair. Simple alopecia areata is caused by contraction of small blood vessels. Alopecia areata can be cured by rubbing with natural vitamin E oil and eating foods rich in vitamin E.
Q: How much vitamin E is needed to maintain human health? What is the best supplementary dose? Maximum safe intake?
Requirements: Dietary reference intake, 30 mg in total.
Optimal supplementary dose: 200-400 mg.
Maximum safe intake: 1200mg, and no poisoning was found; 800 mg a year, in good condition.
Q: What is the latest intake standard of vitamin E issued by China Nutrition Society?
Answer: 30-300mg (the best dose is 200mg).
Q: When is the best time to take natural vitamin E?
A: Natural vitamin E is a fat-soluble vitamin. It is best to take it after meals, because the digestive organs are most active after meals and are easily absorbed by the human body.
