Generally speaking, acidic foods make the skin weak, while alkaline foods make the skin healthy. If you eat too much acidic food, the blood acidity will increase, the blood activity of the whole body will slow down and you will feel tired. On the contrary, alkaline food can improve the state of blood, make the whole body refreshed, prevent and treat skin diseases such as dermatitis easily caused by people with weak skin, and prevent premature roughness and aging of the skin.

So, how to distinguish acidic food from alkaline food?

Strongly acidic foods: beef, pork, chicken, tuna, oysters, flounder, cheese, rice, wheat, bread, wine, peanuts, sausages, sugar, biscuits, white sugar, etc.

Weakly acidic foods: ham, eggs, lobster, octopus, squid, buckwheat, cream, peas, eels, river fish, chocolate, onions, hollow powder, fried tofu, etc.

Strongly alkaline foods: milk, tea, persimmons, cucumbers, carrots, radishes, spinach, oranges, grapes, taro, kelp, figs, raisins, etc.

Weak alkaline food: potatoes, cabbage, bamboo shoots, mushrooms, rape, pumpkin, tofu, apples, pears, bananas, cherries, etc.

When eating acidic food, especially meat, be sure to eat enough vegetables at the same time. Calcium and potassium in vegetables can neutralize sulfuric acid and phosphoric acid in meat.

In addition, calcium can strengthen the skin, enhance the skin's resistance and eliminate allergies. Calcium can also reduce the permeability of blood vessel wall, prevent inflammation and have therapeutic effect. Foods rich in calcium include milk, small fish, shellfish, dried fish and seaweed.

Vitamin c has a reducing effect, which can inhibit the increase of pigment, make the skin fair and prevent sunburn. Foods rich in vitamin C include lemon, citrus, tomato, strawberry, radish, cabbage, rape, apple, watermelon, cucumber and cantaloupe.

Fair complexion and sufficient blood color are the standards of healthy and beautiful skin. Poor skin color is mainly caused by anemia, so eat more iron-rich foods, such as cherries, spinach, carrots, sesame seeds, laver, broad beans, shellfish, sardines, dried fish and so on. Green tea contains more chlorophyll and vitamin C, which can make the skin fair and full of blood.
