Salmon can not only meet the needs of our taste buds, but also provide us with strong antioxidant capacity. The secret is that the red meat of salmon is rich in a nutrient called astaxanthin, which is a very powerful antioxidant. Omega-3 fatty acids contained in fish are essential substances for brain, retina and nervous system, and have the functions of enhancing brain function, preventing Alzheimer's disease and preventing vision loss.

2. tomatoes

Tomatoes can enhance the body's resistance, resist aging and oxidation, and keep people young. This is mainly because lycopene in tomatoes also has antioxidant capacity. At the same time, eating 50 ~100g of fresh tomatoes every day can meet the human body's demand for several minerals and vitamins.

3. Fungal plants

Mushrooms and other fungi have antioxidant capacity, mainly because they have a substance called polysaccharide. The antioxidant activity of polysaccharide is very stable. Whether it is heated at high temperature or in oxygen environment, it will not affect the performance of antioxidant capacity at all, and it has a good scavenging effect on hydrogen peroxide in the body.

4. Green tea

As the most popular drink in China, the benefits of tea to human body are well known. Tea polyphenols contained in green tea have strong antioxidant and physiological activity, and are scavengers of human free radicals. Studies have proved that 1 mg tea polyphenols is equivalent to 9 micrograms of superoxide dismutase in scavenging excessive free radicals harmful to human body, which is much higher than other similar substances. Tea polyphenols can block lipid peroxidation and remove active enzymes.

Experiments show that the anti-aging effect of tea polyphenols is 18 times stronger than that of vitamin e, but tea polyphenols are particularly sensitive to oxygen and light. As long as green tea is exposed to the air or sunlight, the tea polyphenols in it will be quickly lost. Therefore, if you want to make full use of the antioxidant effect of green tea, you must drink sealed, dark and refrigerated tea.

5. wine

Grape seeds have antioxidant capacity, which is mainly reflected in the anthocyanins in grape seeds. This substance has strong antioxidant capacity, which is 20 times that of vitamin C and 50 times that of vitamin E.

Grape seeds will be added in the process of wine brewing, and the antioxidant capacity will be further enhanced in the fermentation process. Therefore, drinking a glass of wine before going to bed is not only good for the quality of sleep, but more importantly, it can prevent the body from aging and keep young.
