First of all, there are many kinds of alkaline foods. Fruits are divided into apples, bananas, grapes, grapefruit, lemons and so on. Vegetables are divided into tomatoes, celery, eggplant, rape and so on. And some soybeans are also alkaline foods, so alkaline foods are foods containing more potassium, sodium, calcium and magnesium, and strongly alkaline foods are grapes, tea and kelp.
Secondly, there is no difference between good and bad food, and the nutritional value is the same, but alkaline food is good for losing weight. Many people think that sour food is acidic food, which is a wrong view. Acidic and alkaline foods are not judged by taste, but by the metabolites of the body. If the metabolite is alkaline, then the food is alkaline.
One more thing, even if you don't need to lose weight, don't eat too much acidic food. Acidic food will acidify body fluids, break the normal pH value of the body and cause various health problems. In any case, a balanced diet and proper exercise can bring good health.
