Free radicals can lead to chronic diseases and aging effects. A large number of studies have confirmed that the human body has the ability to scavenge excessive free radicals, which mainly depends on endogenous free radical scavenging systems, including some enzymes such as superoxide dismutase (SOD), catalase and glutathione peroxidase, as well as some antioxidants such as vitamin C, vitamin E, reduced glutathione, carotene and selenium.
Prevent aging and scavenge free radicals.
Apart from the irresistible factor of age, people will age, lose their physical strength, lose their luster and elasticity. The main reason is too many free radicals in the body. When they are young, there is a good neutralization system in the body to eliminate free radicals and reduce the damage caused by free radicals. However, with the increase of age, the ability of human body to repair free radicals is also declining; If antioxidants are not supplemented in time, cells will begin to be damaged and diseases will arise. More and more evidence shows that the higher the free radical content in the body, the shorter the life span.
So when do you start anti-aging treatment? In principle, it is best to start treatment before or when the body organs are aging. In addition to receiving health professional consultation, it is important to start from your own life. Due to improper living and eating habits, free radicals will be produced in the body, which will further destroy the lipids, protein and nucleic acids in the chromosomes of cells, leading to the mutation of cells into cancer cells.
1. Refuse to smoke: Scientific research smoking is the fastest and strongest free radical generation method at present. Every cigarette will produce more than100000 free radicals, which will lead to systemic cancer and even accelerate the growth of cancer cells. In particular, the risk rate of lung cancer is more than 50 times, and it can cause many chronic diseases, such as cardiovascular disease and diabetes. Studies have confirmed that the hazards of first-hand smoke and second-hand smoke are the same.
Second, reduce cooking fumes: China people like cooking and frying, and most housewives use salad oil for cooking. Salad oil is a polyunsaturated fatty acid, which is easily oxidized into free radicals. Recently, relatively safe oils contain more than 50% monounsaturated fatty acids. For example, olive oil contains 70% unsaturated fatty acids, which is a good edible oil. And try to eat less fried food, so for the sake of health, American fast food restaurants and Chinese cafeterias are rare.
Third, try to take less unnecessary drugs: some drugs, including Chinese and western medicines, are toxic, such as antibiotics, anti-inflammatory drugs and chemotherapy drugs, which will produce free radicals. Don't think that drugs can cure diseases and protect yourself from getting sick. If you are sick, you need to see a doctor and take medicine to eat. You shouldn't take medicine casually.
Fourth, avoid pesticide pollution: pesticides will produce a lot of free radicals. The appearance of fruits and vegetables is not good-looking, and even agricultural products bitten by insects are safer and have less pesticides. Another way to reduce pesticide residues is to put fruits and vegetables in the refrigerator for one or two days before use, which can reduce pesticide residues by 80% to 90% and clean the refrigerator frequently.
Fifth, drink more clean water: healthy drinking water should drink more than 2000 ml of clean water every day. Scholars in Taiwan Province Province found that more than 80% of the heavy metals in human bodies in Taiwan Province Province exceeded the standard, and the most common heavy metals were mercury, lead and cadmium. Therefore, we should pay more attention to the health of drinking water. Natural qualified mineral water is a good choice, so is reverse osmosis water. Canned drinks containing various additives are not good hydrating products, but pure water is the best hydrating product.
6. Eat more vegetables and fruits: A healthy diet should be that the ratio of vegetables and fruits to meat is seven to three every day. Vegetables and fruits contain natural vitamins and flavonoids that resist free radicals, and cellulose that increases intestinal peristalsis. It is best to eat practical fruits and vegetables raw to avoid the loss of vitamins and flavonoids. Eat more than three colors of fruits and vegetables every day and supplement enough vitamins and flavonoids.
7. Eat less animal-derived high-fat foods: Fish, eggs, milk and beans are rich in protein, so they should be properly ingested. The results showed that in the process of smoking and barbecue with high fat and high protein foods, meat oil dripped into charcoal, cracked at high temperature, and reacted with charcoal fire to generate a highly toxic carcinogen-polycyclic aromatic hydrocarbons, which volatilized with smoking and returned to food. Cooking at high temperature will cause protein and amino acids to crack, resulting in amine derivatives, which will cause cancer.
8. Reduce the intake of processed food: Pigments, preservatives and spices will be added during food processing. If you eat too much, too many free radicals will enter the body. For example, pickled food contains nitrate. If it is added in excess during processing, it will react with amines in meat and vegetables in the stomach to generate ammonium nitrate, which is a high carcinogen.
