Wheat bran, a by-product of wheat processing flour, is yellow, flaky or powdery. Rich in cellulose and vitamins, it is mainly used in food, medicine, feed raw materials, wine making and so on. The seed coat screened after wheat milling is the outer skin, mainly fiber, batter, some minerals and vitamins, which is sweet and cool and can inhibit sweating.

Moreover, wheat bran contains substances that enhance immunity, such as magnesium, zinc and iodine. Taking proper amount of wheat bran every day can reduce the production of estradiol. Estradiol is an estrogen that may cause cancer. Pay attention to when eating, wheat bran should be mixed with grains and baked goods.

2. Propolis

Propolis is flat, bitter, pungent and slightly sweet, and has the effects of moistening skin, promoting granulation, diminishing inflammation and relieving pain. Moreover, propolis can improve the ability of human macrophages to swallow viruses and bacteria, and make the immune system in the best dynamic balance state, so it is called "natural immune enhancer".

Step 3: garlic

Allicin fights infection and bacteria. The experimental results of British researchers show that eating garlic can reduce the chance of catching a cold by 2/3. People who chew garlic regularly are also less prone to colon cancer and stomach cancer. So eat two cloves of garlic raw every day and add some minced garlic when cooking.

Extended data:

Protecting immunity is a trivial matter.

1, ensure less sleep and stay up late.

Working late at night, playing games and chasing dramas are common problems of people in the information age, which not only bring about lack of sleep and chronic diseases, but also "accidentally hurt" immunity. Staying up late will disturb the body's biological clock, make the liver and kidney function decline, and at the same time lead to the increase of protein consumption and the decrease of synthesis, thus hindering the synthesis of immunoglobulin and leading to the decline of immunity.

2. Control your weight and eat less sugar

Research by McMaster University in Canada shows that obesity has become the main risk factor for people to get influenza. Obesity reflects the disorder of glucose and lipid metabolism in the body, and this group of people is also prone to a variety of chronic diseases. This is because various organs, including immune organs, are overloaded for a long time, which leads to the weakening of various functions of the body to varying degrees.

3. Combine work and rest and have more rest

Many people have this experience, feel very tired, and soon start to have headaches and brain fever. This is because fatigue can also affect the body's immune system. If you exercise enough and eat on time, but still feel tired, then consider whether it is too intense exercise or unbalanced diet.

Many times, people are tired because they don't have enough exercise or have too much workload. At this time, the organs of the body are still running at high speed, but the metabolic level can not be improved, which leads to the overload operation of the body system, thus bringing a burden to the immune system. Long-term physical fatigue will also cause mental fatigue, and the immune function will gradually decline, and it will be unable to resist the invasion of external viruses and bacteria, thus getting sick.
