2. Antioxidant foods include salmon, broccoli, tomatoes, sweet potatoes, oats, spinach and almonds.
Antioxidant refers to the abbreviation of antioxidant free radical. Due to the constant contact with the outside world, including breathing (oxidation reaction), external pollution, radiation exposure and other factors, free radicals are constantly produced in the human body.
Scientific research shows that cancer, aging or other diseases are mostly related to the production of excessive free radicals. The research on antioxidation can effectively overcome its harm, so antioxidation is listed as one of the main research and development directions by health care products and cosmetics enterprises, and it is also one of the most important functional requirements in the market.
brief introduction
Antioxidant is any substance that can effectively inhibit the free radical oxidation reaction at low concentration. Its mechanism of action can be directly acting on free radicals or indirectly consuming substances that are easy to produce free radicals to prevent further reactions. When the human body inevitably produces free radicals, it also naturally produces antioxidant substances that resist free radicals.
To combat the oxidative attack of free radicals on human cells. Studies have proved that the human antioxidant system is a perfect and complex system comparable to the immune system. The stronger the antioxidant capacity of the body, the healthier it is and the longer its life span.
Antioxidants in the human body are synthesized by themselves and supplied by food. Enzymatic and non-enzymatic antioxidants play an important role in protecting the peroxide damage caused by exercise.
Supplementing plant active selenium to enhance antioxidation is beneficial to reduce the generation of free radicals in exercise or accelerate the elimination of free radicals to counter the side effects of free radicals, so it is beneficial to the health of ordinary people and athletes, which may delay the occurrence of exercise fatigue and accelerate the recovery of physical fitness. Older physical exercisers take antioxidants better than young people.
