Oats are cold-tolerant, drought-tolerant, adaptable to soil and self-propagating. Oats are rich in dietary fiber, which can promote gastrointestinal peristalsis, facilitate defecation, have low calories, low glycemic index, reduce blood fat and sugar, and are also one of the advanced supplements. Oat grains are used for grinding or as feed, and have high nutritional value. Among the nine kinds of food that Chinese people eat daily, such as wheat, rice and corn, oats have the highest economic value, which is mainly manifested in its high nutritional, medical and feeding values. β -glucan in oats can slow down the increase of glucose content in blood and prevent obesity, diabetes and cardiovascular diseases. Oats are rich in dietary fiber and have the function of cleaning up intestinal garbage.

First, the beauty effect

Moisturizing and moistening

Protein is one of the most important ingredients in oatmeal. Small peptides and amino acids can be obtained by protein enzymolysis. These molecules all contain hydrophilic groups, which can absorb or lock water in the stratum corneum of the skin and have a very good moisturizing effect. Oat protein with high molecular weight can form a film at low concentration, which plays the role of embedding or isolating small molecular substances, and can quickly transport active ingredients or release them at regular intervals, improving hair quality and skin dryness. Protein, peptides and amino acids are also essential nutrients for the growth and development of tissues and cells. Adding these substances into cosmetics can also moisturize the skin, nourish cells and promote the healthy growth and development of skin tissues. Oats are rich in high-quality oils, mainly composed of unsaturated fatty acids. The fat composition and hydration characteristics of oat can emulsify a lot of water in oil and can be used as an effective carrier of epidermal hydration humectant. Oat oil can also form an oil film on the skin surface, which plays a long-term moisturizing role; Unsaturated fatty acids in oat essential oil can soften the skin, nourish and beautify the face, and give people a comfortable skin feeling.

Whitening freckle removing

The color of skin mainly depends on the content of melanin in epidermis. Melanin in the human body is produced by melanocytes. In melanocytes, tyrosine undergoes a series of biochemical reactions under the catalysis of tyrosinase. Tyrosinase is the main rate-limiting enzyme for melanin formation. Inhibition of tyrosinase activity can inhibit the formation of melanin. At the same time, antioxidants can inhibit the biochemical reaction of melanin formation, so they can also reduce the formation of melanin. Oat extract contains a large number of bioactive components that can inhibit tyrosinase activity, and its inhibitory ability is close to arbutin, a whitening agent commonly used in cosmetics at present, indicating that the whitening effect of oat extract is equivalent to arbutin, but the cost of oat extract is much lower than arbutin. In addition, oats contain a lot of antioxidant components, which can effectively inhibit the redox reaction in the process of melanin formation, reduce the formation of melanin, dilute pigmentation and keep the skin fair and beautiful.

Second, summer health

The weather is getting hotter and hotter, and people's diet is getting lighter and lighter. Many people are not as active as usual at first, partly because of the hot weather, and people are unwilling to cook breakfast or eat hot food by themselves. The busy living environment also makes people ignore the importance of breakfast. The first meal in the morning is actually the most critical meal for nutritional intake. In times of great pressure, white-collar workers go out early and return late to work hard for their families and careers. Balanced nutrition can supplement their physical strength and bring vitality to the day. So what should we eat for breakfast in summer? Nutritionists tell us that it is best to eat oatmeal.

Oatmeal is easy to satiate and has long-lasting energy. Oatmeal is rich in high molecular carbohydrates and dietary fiber. The unique water-soluble fiber β -glucan can prolong the digestion time of carbohydrates, which can not only provide energy continuously and stably, but also bring abundant energy all day, ensuring health and providing lasting energy, so that you can prepare for the coming summer. Even if children exercise a lot in summer and consume a lot of physical energy, they can make you and your family energetic and do a good job in study and work. Healthy eating methods of oats in summer, such as Quaker's new instant oatmeal, are basically oats that can be eaten quickly. You can add various ingredients or fruits in different cooking methods to present another fashionable way to eat. Control your blood sugar, beauty beauty. Modern people eat more finely to prevent the small intestine from affecting starch.

Third, health care function.

1, hypolipidemic effect:

Oats can obviously reduce the serum cholesterol of newly weaned mice and 2 1 healthy young men. Among the 265,438+0 young men, the cholesterol decreased obviously after taking it for three weeks, but it returned to the original level after stopping using it for two weeks. The data show that oats have a strong effect on controlling the increase of blood lipid, especially lowering cholesterol. At present, although some chemically synthesized lipid-lowering drugs have obvious lipid-lowering effects, they all have obvious side effects of liver swelling and weight gain, and even cause serious consequences of cancer if taken for a long time. The mortality rate of patients treated with these drugs increased by 2.7%, while oat has similar good lipid-lowering effect, preventing the increase of blood lipid, and it is safe and non-toxic for long-term use. Therefore, physicians and nutritionists prefer to eat oats to reduce blood lipid and prevent arteriosclerosis.

2. Cancer prevention:

According to the records of traditional Chinese medical literature and international research reports on tumor suppression, there is the possibility of preventing canceration substances in wheat resources. At present, the research of oat inhibiting tumor has begun to take shape. It was observed that the animals that only ate oats had small tumor growth and long survival time, but they did not reach the standard of tumor inhibition rate of 30% and survival time extension rate of 50%, so they were considered active. However, this result and discovery are enough to prove that there are anticancer substances in oats. As for the effective components and mechanism of action, there is no report yet, and the research in this area needs to be further deepened.

3. Anti-hyperviscosity and platelet aggregation:

Oats also have anti-high blood viscosity and anti-platelet aggregation effects. The results showed that 6g oat flour could significantly reduce the plasma viscosity and whole blood viscosity of rats fed with high-fat diet at high shear rate and low shear rate, and significantly inhibit platelet aggregation induced by ADP and collagen. Therefore, oat flour may have the function and efficacy of preventing thrombosis, and there is no relevant research report at present.

4. Control obesity:

1993, a 39-year-old cake king in Washington, USA, weighed 150kg, with a TC of 3.24mg/mL. Usually, you can only stay in bed, and then eat 2~3 oatmeal cakes (whole oatmeal food, 25g each) every day according to the doctor's advice. After 3 months, my weight dropped to 125kg and TC to 1.75mg/mL. This shows that oats can prevent obesity.

Four, oatmeal nutrition recipes

1. Assorted fruits:

Put 2 tablespoons of instant oatmeal and 1 tablespoon of black sesame powder into a bowl, add diced apple and diced banana, add appropriate amount of boiling water and stir well, then put it in a microwave oven for 3 minutes, then take it out and drop two drops of olive oil.

Nutrition comments: There is not much vitamin C in apples and bananas, so don't worry about heating loss. But potassium, magnesium, fructose and soluble dietary fiber are more. Together with oats, it is more conducive to cardiovascular health care, stabilizing blood sugar and lowering blood cholesterol. This kind of porridge is very suitable for eating in winter morning, warming the stomach and refreshing.

2. Milk flavored custard:

Cut 10g cheese into fine powder, mix it with 2 tablespoons oatmeal (ground with oatmeal), 1 beaten egg liquid and 1 bag of milk, and pour it into a covered bowl or seal it with high-quality plastic wrap. After the steamer is inflated, steam for 10- 15 minutes.

Nutrition Comments: If there are young children or frail old people at home, you can grind oats into powder and make egg soup to eat together. Not only will nutrition not be lost, but it will be better absorbed. Besides high-quality protein, lecithin and lutein, eggs also contain vitamin D, which can help the absorption of calcium in milk and cheese. This dish is especially good for supplementing calcium.

3. Dried fruit bee cake:

Mix oats, corn flour, soybeans, raisins and medlar, add yeast powder and mix well, and add water to form a slightly soft dough. After baking the dough for 20 minutes, steam it for 25 minutes and turn off the heat.

After oat is made into bee cake, it not only increases the total dietary fiber, but also reduces the sweetness of bee cake without reducing the flavor because raisins and medlar are used instead of sugar. Oats and corn lack lysine, while soybean flour is rich in lysine, which can enhance the absorption and utilization of protein.
