This study was conducted in China. Participants were divided into two groups, taking supplements containing vitamin E and placebos without vitamin E respectively. The results showed that participants who took vitamin E supplements had lower cancer mortality. Further analysis showed that with the increase of blood concentration of vitamin E, the risk of esophageal cancer and some types of gastric cancer decreased. On the contrary, γ-tocopherol, another molecular structure of vitamin E, has no such effect.
The function of 12 vitamin c
Vitamin C has a strong effect on skin, bones, blood vessels and stress. Taking vitamin C can improve physical condition, which is very helpful from metabolism to disease prevention and treatment. Its function is not only to treat colds and beautify the skin, but also to help the body function and treat diseases. It is an indispensable nutrient for maintaining life.

Efficacy 3: Help skin and bones to produce collagen and maintain bone density.
Efficacy 4: Avoid arteriosclerosis, heart disease and cancer, and let acidified fat recover.
Efficacy 5: Help the accessory kidney cortex secrete hormones to resist stress.
Efficacy 6: Reduce bad cholesterol (LDL) and improve good cholesterol (HDL).
Efficacy 7: Taking enough vitamin C can inhibit the rise of blood pressure.
Efficacy 8: Produce ingredients to avoid blood coagulation, thus avoiding stroke and heart disease.
Efficacy 9: Metabolism of drugs and food residue drugs in the liver, with detoxification function.

Efficacy: 1 1: Inhibit skin inflammation after sun exposure and eliminate freckles and wrinkles.
Efficacy 12: increase the body's adaptability to temperature changes and avoid heatstroke.
1. What is dietary fiber?
Dietary fiber is a kind of carbohydrate that human body can't digest, which can be divided into two categories: water-insoluble fiber and water-soluble fiber. Cellulose, hemicellulose and lignin are three common water-insoluble fibers, which exist in plant cell walls. Pectin and gum are both water-soluble fibers and exist in non-fibrous substances in nature.
Second, the importance of dietary fiber.
Dietary fiber plays an important role in promoting the good digestion and excretion of solid waste. Appropriate cellulose supplementation can increase and soften the food in the intestine, promote intestinal peristalsis, thus speeding up defecation, preventing constipation and reducing the risk of intestinal cancer.
In addition, cellulose can also regulate blood sugar and help prevent diabetes. It can also reduce the absorption of fat during digestion, thus reducing the levels of cholesterol and triglyceride in blood, and preventing and treating hypertension and cardiovascular and cerebrovascular diseases.
Third, the daily intake standard:
The daily intake of dietary fiber recommended by relevant international organizations is 30-40g per person per day recommended by American Cancer Society and 30g per person per day recommended by European Committee for Homogeneous Food Science.
4. What food contains the most dietary fiber?
Brown rice and embryo polished rice, as well as miscellaneous grains such as corn, millet, barley, wheat bran and wheat flour (the material of black bread); In addition, there are many dietary fibers in root vegetables and seaweed, such as burdock, carrot, mung bean, red bean, pea, potato and Undaria pinnatifida.
Dietary fiber is a kind of indigestible food nutrient. It mainly comes from plant cell walls and contains cellulose, hemicellulose, resin, pectin and lignin.
Fiber can be divided into two basic types according to its solubility in water: water-soluble fiber and water-insoluble fiber. Water-soluble fibers include resin, pectin and some semi-fibers. Common foods, such as barley, beans, carrots, oranges, flax, oats, oat bran, etc., are rich in water-soluble fiber, which can slow down digestion and expel cholesterol as quickly as possible, so that blood sugar and cholesterol in the blood can be controlled beyond the ideal level, and it can also help diabetic patients reduce insulin and triglycerides.
Water-insoluble fibers include cellulose, lignin and some semi-fibers, as well as wheat bran, corn husk, celery, peel and root vegetables from food. Insoluble fiber can reduce the risk of intestinal cancer, prevent constipation and diverticulitis by absorbing toxic substances in food, and reduce toxins discharged by digestive tract bacteria. Most plants contain water-soluble and water-insoluble fibers, so a balanced intake of water-soluble and water-insoluble fibers in the diet can obtain different benefits.
Benefits of dietary fiber:
Keep the digestive system healthy
boost one's immune system
Lowering cholesterol and hypertension
Reduce insulin and triglycerides
◇ Relaxation, diuresis, clearing intestine and invigorating stomach
Prevent cardiovascular diseases, cancer, diabetes and other diseases.
Balance hormones in the body and reduce hormone-related cancers.
Dietary fiber is indispensable for a healthy diet. Fiber plays a vital role in keeping the digestive system healthy. At the same time, taking enough fiber can also prevent cardiovascular diseases, cancer, diabetes and other diseases. Fiber can clean the digestive wall and enhance the digestive function. At the same time, fiber can dilute and accelerate the removal of carcinogens and toxic substances in food, protect the fragile digestive tract and prevent colon cancer. Fiber can slow down digestion and excrete cholesterol as quickly as possible, so it can control blood sugar and cholesterol at the best level.
