A healthy human body must remain slightly alkaline, and the PH value should be around 7.3. If human blood is acidic, blood viscosity and cholesterol are relatively high, people are prone to fatigue, and the body's resistance will also decline. And almost all meat dishes are acidic foods (except milk and blood products), which are rich in protein, carbohydrates, fat and so on. Holiday diet should not only eat big fish and meat, but also have alkaline food to match it to achieve the acid-base balance of the human body. The highest alkali content is kelp, followed by green vegetables, lettuce, lettuce, celery, mushrooms, carrots, radishes and so on.
2, potassium and sodium.
China residents' salt intake is already high, which is more than twice the amount recommended by the World Health Organization. During festivals, if you eat more non-staple food, you will eat more salt, and then your blood sodium content will be higher, which is not conducive to maintaining normal blood pressure. Potassium is the bane of sodium, which can excrete excess sodium from human body. Potash-rich vegetables include laver, kelp, mushrooms, asparagus, pea seedlings, lettuce, celery and so on.
3. "More slag" mixed with "less slag"
Meat dishes do not contain dietary fiber, and livestock and aquatic products are also fine "food with less residue". Eating too much will cause constipation, and toxic waste such as feces will stay in the intestine for too long, which will increase the absorption of toxins by intestinal mucosa and easily induce colon cancer. Crude fiber food belongs to "slag-rich food", and eating more of this kind of food can eliminate the harm caused by "slag-poor food" to human body. Foods containing more crude fiber mainly include millet, corn, cereals, peanuts, fruits, Chinese cabbage, radishes and so on.
