Those that contain a lot of sodium, calcium, potassium, magnesium, iron, copper and other ingredients can be classified as alkaline. Such as tofu, soybeans, green beans, spinach, lettuce, turnip, radish, bamboo shoots, sweet potato, potato, onion, eggplant, cucumber, watermelon, kelp, citrus, star fruit, banana, apple, grape, persimmon, milk, protein, coffee , strawberries, cabbage, etc.

There are many factors that affect blood pH, and diet is the most direct and lasting factor. Although blood has a strong balancing ability, an unreasonable diet for a long time will cause fluctuations in blood PH value.

If you eat too many acidic foods for a long time, it will change the normal weakly alkaline environment in the body, make the body fluids acidic, worsen blood circulation, and reduce skin metabolism. The skin will become rough, lose its luster, become more stained, and have enlarged pores.

The pH value (pH value) of the internal environment of a healthy person is between 7.35 and 7.45, that is, the body fluid should be weakly alkaline to maintain normal physiological functions and material metabolism. According to surveys, only 10% of people have a pH value within this range and have an alkaline constitution; while as many as 70% of people have an acidic constitution, with the pH value of body fluid always hovering around 7.35 or slightly lower, and the body is in a sub-healthy state.

People who want to adjust their own pH should not only exercise more and adjust their psychology, but also pay special attention to supplementing alkaline foods and eating less acidic foods.

Among animal foods, except for milk, most are acidic foods. Among plant foods, except for cereals, grains, and beans, most are alkaline foods. Salt, coffee, oil, sugar, tea, etc. are all neutral foods.

But there are a few exceptions. For example, plums should be alkaline foods, but the organic acids they contain cannot be metabolized by the human body, so they will remain in the body to show an acidic reaction. Oranges or lemons are different. They contain organic acids that cannot be metabolized by the human body and are alkaline foods.

Strongly acidic: egg yolks, cheese, pastries made with white sugar or mullet roe, persimmons, dried fish, etc.

Medium acidity: ham, tuna, pork, chicken, eel, beef, bread, butter, wheat, horse meat, etc.

Weakly acidic: red beans, cabbage, onions, radishes, apples, tofu, etc.

Medium alkaline: dried radish, soybeans, oranges, papaya, carrots, tomatoes, strawberries, prunes, lemons, spinach, etc.

Strongly alkaline: grapes, wine, tea, kelp, etc. Especially natural green algae, which is rich in chlorophyll and is a good alkaline health food.

Pay attention to the reasonable combination of acid and alkaline foods to maintain a healthy internal environment.
