1. Alkaline foods: Alkaline foods contain more metal elements such as sodium, potassium, calcium, and magnesium. It does not mean that something sour is sour food. You should know one thing: all sour fruits and soy products are alkaline foods, not acidic foods. Alkaline foods are considered to be foods with beauty effects. Tofu, milk, celery, potatoes, bamboo shoots, mushrooms, carrots, kelp, mung beans, bananas, watermelons, strawberries, etc. and most vegetables and fruits are alkaline. The "acidity and alkalinity" of food will affect body posture and skin fitness. It has been determined that weakly alkaline foods include: tofu, peas, soybeans, mung beans, rape, celery, sweet potatoes, lotus roots, onions, eggplants, pumpkins, cucumbers, mushrooms, radishes, milk, etc. Alkaline foods include: spinach, cabbage, cabbage, lettuce, carrots, bamboo shoots, potatoes, kelp, citrus, watermelon, grapes, bananas, strawberries, millet, persimmons, coffee, wine, etc. There are also some foods that taste sour, so people mistakenly regard them as acidic foods, such as wild plants, tomatoes, vinegar, etc. In fact, these foods are typical alkaline foods. Tip: Eat more alkaline foods. Studies have found that eating more alkaline foods can keep the blood weakly alkaline, reduce acidic substances such as lactic acid and urea in the blood, and prevent them from depositing on the wall of the blood vessels, thus softening the blood vessels, so some people call it alkaline. Food is a "cleanser of blood and blood vessels." The acidity and alkalinity mentioned here is not the nature of the food itself, but the nature of the elements left in the body after the food is digested and absorbed. Common acidic elements include nitrogen, carbon, sulfur, etc.; common alkaline elements include potassium, sodium, calcium, magnesium, etc. Some foods have a very sour taste, such as tomatoes and oranges, but they are all highly alkaline foods, because the final element they metabolize in the body is potassium. 2. Acidic foods: Acidic foods refer to foods that contain inorganic salts such as phosphorus, sulfur, chlorine and other elements that can form acids in the human body, and can cause body fluids to become acidic. Common foods include protein-rich meat, fish, poultry, Eggs, cereals, and hard fruits such as peanuts, hazelnuts, and walnuts. Specific examples include: pork, beef, chicken, egg yolk, carp, eel, dried squid, shrimp, rice, flour, bread, barley, beer, asparagus, etc. Although your body lacks acidic foods, you should not blindly supplement them, because medical science has proven that when we eat a large amount of acidic foods containing chlorine, sulfur, phosphorus and other acidic foods, it is extremely difficult for the blood to maintain a weak alkaline state, and acidosis is prone to occur. disease. You should know that adding MSG to acidic food and heating it at the same time will cause pyropyridonation into pyroglutamic acid, which not only cannot reduce the sourness, but is also very harmful to the human body. Adding MSG to alkaline food will greatly reduce the flavor of MSG due to racemization under alkaline conditions. It does not mean that the higher the temperature, the greater the loss of nutrients. It has been confirmed that when cooking at a temperature of 66 degrees, spinach loses 90 percent of its vitamin C, while at 95 degrees, only 18 percent is lost. The reason is that the mold that decomposes vitamins is more active at 50 to 65 degrees, and above 70 degrees, this mold is inhibited and the vitamins are no longer destroyed. Therefore, stir-frying over high heat and adding a little vinegar in an appropriate amount can avoid vitamin damage. What are acidic foods? What are alkaline foods? Recently, people have been talking about acidic and alkaline foods, so how to reasonably combine alkaline foods? This should be discussed from the environment inside the human body. The human body's internal environment is basically neutral, slightly alkaline. A large amount of acidic substances produced during metabolism are neutralized by buffer substances in the blood, preventing the internal environment of the human body from becoming acidic, but sometimes it can cause disorders. Every time you eat a meal, the food has a certain pH, which will also affect the body's acid-base balance. But generally speaking, it is a basic requirement to pay attention to an alkaline diet and maintain a weakly alkaline environment in the body.
