We must emphasize that three meals with balanced nutrition, eight or nine full meals, daily exercise and prevention of overweight are the most effective basic strategies for health preservation and old age prevention. There is also the need to avoid alcohol and tobacco as much as possible, because both can obviously accelerate cell oxidation. With these basic health habits, it is the real icing on the cake to take health food with the functions of "prevention and anti-aging" instead of "giving up the basics".

It is very important to choose health care products that are safe, theoretical and suitable for your own physique. Generally speaking, people under 40 choose to take antioxidant vitamins such as vitamin C, E and beta carotene. Combined with some organic plant products containing antioxidant components, such as green wheat seedling juice powder and cruciferous plants such as cauliflower juice. And insist on taking it every day to gradually reduce the concentration of free radicals in the body and normalize the immune system, which will take effect in about three to five months. If the body that used to catch a cold and get tired easily will gradually get better, you should not stop supplementing antioxidant products to maintain health, because it is impossible for people to leave this environment full of free radicals. Even if the concentration of free radicals in the body is reduced by taking antioxidant substances, once the external environment has not improved, the concentration of free radicals in the body will rise again.

Another point that needs special attention is that vitamin preparations should be taken after meals, while plant extracts containing antioxidant components should be taken on an empty stomach before meals, which is more effective. As for collagen, placenta, dehydroepiandrosterone (DHEA), etc. The effect is still in the evaluation stage, except cosmetics, it must be used with caution.
