Nutritional efficacy
Matters needing attention
efficacy
Wheat germ is one of the organs of wheat germination and growth, accounting for about 2.5% of the whole wheat grain, and is the part with the highest nutritional value in wheat. It is rich in protein, vitamin E and vitamin B 1, which not only contains comprehensive, rich and balanced nutrition, but also can maintain the normal functions of human heart, blood, bones, muscles and nerves if eaten regularly.
1, enhance physical strength
Wheat germ also contains 22, 25, 26, 28 and other enols. These higher alcohols have certain effects on improving the collective basal metabolic rate, reaction time, reflexivity, sensitivity, muscle function, enhancing the body's heart load function, enhancing physical strength, endurance and explosive force, among which octacosanol has attracted much attention because of its various physiological activities.
2. Promote intestinal health
Wheat germ contains a large amount of dietary fiber, which can not only lower cholesterol and blood sugar, but also moisten the intestines to relieve constipation, accelerate the discharge of carcinogens and avoid intestinal cancer.
3. Promote growth and development
Wheat germ is rich in minerals such as magnesium, phosphorus, potassium, zinc, iron and manganese. , which is necessary for human body, has a comprehensive variety, especially the trace element selenium is higher than other foods. These mineral elements play an important role in maintaining human health, especially in promoting children's growth and development.
4. Prevention of arteriosclerosis
The fat in wheat germ is a kind of high-quality plant fatty acid, of which 84% is unsaturated fatty acid beneficial to human body, especially linoleic acid, which is the most important of the three essential fatty acids for human body, accounting for more than one tenth of the whole wheat germ oil. It can react with cholesterol in human blood vessels and prevent arteriosclerosis.
5, improve immunity
According to the determination, wheat germ contains 30% protein, including globulin 18.9%, glutenin 0.3% ~ 0.37% and maltitol protein 14%, which is an important nutritional source in protein. Wheat germ protein is a kind of high quality protein. The content of eight essential amino acids in human body accounts for 34.74% of the total amino acids, of which lysine accounts for 1.85%. The biological potency of protein is equivalent to that of protein model food eggs. Long-term consumption of wheat germ can improve immunity.
6. Beauty and skin care
Wheat germ is far richer in vitamin E than other plants, ranking first among all vegetable oils, and contains complete vitamin E ... Among them, α and β bodies account for a large proportion, accounting for about 60% and 35% respectively, which is incomparable to other foods. Vitamin E is a natural antioxidant, which can effectively fight free radicals, moisturize and protect skin, and delay aging.
7, delay aging
Wheat germ protein also contains glutathione, which has antioxidant and anti-aging effects. Under the catalysis of glutathione, it can react with peroxide to reduce oxide, protect human cells from oxidative damage, especially protect brain function, transfer amino acid biological function and promote growth and development.
nutritive value
Although wheat germ only accounts for 2% of the weight of wheat grain, its nutrition accounts for 97% of the whole wheat grain, which contains more than 50 kinds of rich nutrients needed by human body and some trace physiological active components that have not been discovered by science so far. It has extremely high nutritional value and medicinal value, and its magical effect on human health is recognized by the world.
1. According to modern scientific research, the protein content of wheat germ is above 3 1%, which is a high-quality protein. It contains 8 kinds of essential amino acids, especially lysine, accounting for 18.5%, which is 6-7 times higher than that of rice and white flour.
2. The content of linoleic acid in wheat germ accounts for 60%, of which 80% is polyunsaturated fatty acid. Linoleic acid is the most important of the three essential fatty acids in human body, which can reduce blood lipid and prevent atherosclerosis.
3. Wheat germ is rich in vitamins. The content of vitamin B 1 is 5 times that of flour, 2 times that of rice, 28 times that of soybean, 33 times that of beef and 57 times that of egg. The content of vitamin B2 is 10 times that of flour, 8 times that of rice, 0.7 times that of soybean, 3 times that of beef and 2 times that of egg. In particular, the content of vitamin E is as high as 34.9 mg/100 g. Nutritionists call it the storehouse of natural vitamin E, which can enhance the vitality of brain cells and delay aging.
4. Wheat germ also contains calcium, potassium, magnesium, iron, zinc, chromium, selenium, phosphorus, manganese, copper and other minerals and trace elements.
5. The pigment in wheat germ is wheat flavone, which is a water-soluble pigment and has a good therapeutic effect on cardiovascular diseases.
6. Glutathione in wheat germ, which some people call anti-cancer factor, has a significant effect on inhibiting cancer.
7. Wheat germ contains a lot of dietary fiber, which has the functions of relaxing bowels, lowering blood fat, lowering postprandial blood sugar, losing weight and detoxifying.
8. Wheat germ also contains high carbohydrate, with a content as high as 47%. Among them, hemicellulose 15.3%, cellulose 16.9%, starch 310.5%, sugar 36.3% (sucrose 55.9%, rhamnose 38. 1%, fructose 2.8% and glucose 2./kloc). Wheat germ can effectively provide energy for the body, exert the best antioxidant effect, delay skin aging, greatly promote the development of the body's nervous system, delay the occurrence of Alzheimer's disease, greatly promote the rapid peristalsis of the intestine and relieve constipation in the body. However, after eating too much, it is easy to stimulate the intestines and cause abdominal pain and diarrhea.
A wheat embryo is just a bud of wheat. It contains extremely rich nutrients, including a lot of protein, vitamin B and E, etc. These elements are necessary for human daily life, so they are good for the body, but they also contain some side effects, so we must pay attention to them. So, what are the effects and taboos of wheat germ?
1, which is extremely nutritious.
Wheat germ is rich in nutrients, including protein, amino acids, vitamins B 1, B2, E, various dietary fibers, iron, potassium and zinc, and antioxidant glutathione. Clinical studies have proved that protein in wheat germ is comparable to protein in eggs, and the content of protein in wheat germ is basically the same as that of protein in four eggs, about 50g. Wheat germ also contains 8 kinds of amino acids necessary for human body, and the ratio is extremely reasonable. Its vitamin B 1, B2, iron and potassium are much higher than those in flour. The vitamin E content of wheat germ oil is the champion of oil plants and the biggest treasure house of longevity vitamins.
It can also provide necessary energy substances for the body's metabolism, play an antioxidant role, greatly delay the aging of the skin, promote the early development of the body's nervous system, have a good preventive effect on Alzheimer's disease, promote intestinal peristalsis, and have a good relieving effect on constipation.
2. Possible side effects
But when eating, we should also pay attention to the fact that the fiber content in wheat germ is extremely rich. Eating too much is easy to stimulate the intestines, and then there will be obvious abdominal pain and diarrhea, and then people with spleen and stomach deficiency and cold are not recommended to eat.
The above is the efficacy and taboo of wheat germ. After eating, the human body will absorb many trace elements, including vitamins B 1, B2, E, amino acids and other nutrients. But when eating, if excessive, it will cause abdominal pain and diarrhea, so people who are weak can't eat it.
