3 charred meat
Barbecue greatly increases appetite, but be careful not to eat the black burnt part, which contains pro-inflammatory hydrocarbons and will destroy skin collagen.
4 salty food

Rana Hirsch, former president of the American Society of Aesthetic Surgery, pointed out that processed foods such as canned food will add a lot of sodium in order to keep fresh and extend the shelf life.
5 prepared food

Trans fatty acids can promote inflammation in vivo and destroy collagen synthesis. Experts caution not to believe the description of "0 g trans fatty acid" on food packaging, which may mean that food still contains less than 0.5 g trans fatty acid, and foods with hydrogenated vegetable oil on the ingredient list should be avoided as much as possible.
9 milk tea

10 red meat
Red meat such as beef and mutton contains a certain amount of saturated fatty acids, which will produce free radicals in the body, destroy skin cells and eventually accelerate aging. Dr. Aosta suggested that white meat with low fat content such as chicken can be used instead, and fruits and vegetables can be used to help the human body improve its antioxidant capacity and delay the aging process.
2, food to alleviate aging
1 broccoli
Broccoli is rich in nutrients, including protein, carbohydrates, fats, minerals, vitamin C and carotene. Every 100g fresh broccoli ball contains 3.5g-4.5g of protein, which is 3 times that of broccoli and 4 times that of tomato.

As a kind of fruit or beverage, grape juice has less fermentation process, less antioxidant components and less firepower. The antioxidant capacity of red wine brewed from grapes is improved after fermentation.
The secret of drinking wine is tannic acid. Red wine contains more tannins than white wine. Medicine has proved that phenolic compounds such as tannic acid and red pigment have antioxidant and anti-aging effects. Anti-oxidation is an important step in skin care, and the production of oxidative free radicals in the body damages cells. The anti-aging research done by the medical and aesthetic circles is directly related to anti-oxidation, and even various red wine beauty products, such as red wine masks, have appeared on the cosmetics counter. Chinese medicine advocates dietotherapy, and it is most foolproof to fall directly into the stomach.

Anthocyanin has been proved to prevent the decomposition of collagen, which is mainly concentrated in skin, joints and blood vessels, and is responsible for transporting nutrients to the brain and maintaining skin elasticity. Once this protein is decomposed, the human body will gradually age, so the antioxidant capacity of anthocyanins is 50 times stronger than that of vitamin E.
