Japanese women are famous for their delicate skin, but in recent years they have become rough and greasy. The reason is that, according to Japanese scientists, before the Meiji Restoration in Japan, the Japanese were mainly vegetarian, and the fat needed was mainly from soybeans, sesame seeds and rapeseed, so most of the Japanese skin at that time was moist and delicate. At present, it is mainly caused by eating too much meat and animal fat. At the same time, the high incidence of acne among young people is also related to excessive meat intake. Scientists also said that one of the important reasons for baldness in western countries is that they eat too much animal fat, sebaceous glands are blocked from secreting sebum, hair roots can't keep up with nutrition, and hair is easy to fall off.

Vegetarianism and meat are relative. There are about half a million vegetarians in America.

The concept of vegetarianism abroad is slightly different from ours. In addition to vegetables and bean products, it also includes eggs, milk and a small amount of lean meat. In western countries, white, yellow, green and red are generally called vegetarian four colors. White refers to rice, flour and grain; Yellow refers to beans, and green refers to vegetables and fruits; Red includes the right amount of lean meat and carrots.

Nutrition believes that most foods are either acidic or alkaline.

Generally speaking, vegetarian food is mostly alkaline food, and meat is mostly acidic food.

People who have vegetarian habits and eat too much meat have different blood pH values. The former blood is weakly alkaline, while the latter blood is generally acidic.

Originally, the pH value of various body fluids is generally constant, because body fluids such as blood have a buffer system, and lungs and kidneys also have regulatory functions. However, long-term meat or vegetarian habits can make all kinds of body fluids in a state of excess acid or alkali for a long time.

From the point of view that human blood circulates to transport nutrients and excrete waste, blood must remain weakly alkaline. Because the food we eat, such as protein, fat, carbohydrates, etc., will produce acidic substances such as phosphoric acid, sulfuric acid and lactic acid in the body process, which is harmful to the human body. Weakly alkaline blood can neutralize acidic substances in the body and make them become harmless neutral compounds and excrete them. Therefore, some people call vegetarianism a "blood purifier". People who eat meat lack alkaline substances in their blood, and acidic substances will be brought to all parts of the body. In addition, meat will produce a lot of urea and lactic acid in the process of metabolism in the body, which will directly erode the cells of the skin, making the skin lose its elasticity and tension and become rough.

Some people have body odor, and besides genetic factors, gluttony for meat is also one of the reasons.

Acidic foods or alkaline foods are not directly measured by chemical methods, but can only be displayed after physiological changes have taken place in the human body.

How to judge which foods are acidic and which are alkaline? We know that the most abundant elements in food are chlorine, sulfur, phosphorus, potassium, sodium, calcium and magnesium. The first three are acid-forming elements, and the last four are alkali-forming elements. Generally speaking, the first three elements are mostly acidic foods, and the last four elements are mostly alkaline foods. Like grains (cereals), meat, poultry, aquatic products, eggs, cheese, butter, peanuts, walnuts and so on. After metabolism, strong acidic "residues" are produced, almost all of which are acidic foods. Roots in vegetables and grains (such as sweet potatoes and potatoes). ), fruit, milk, chestnuts, almonds, etc. Can be metabolized to produce strong alkaline "residue", almost all of which are alkaline foods. And some do not contain the above elements, such as refined oil, sugar, starch, etc., and do not produce any residue after metabolism, so they are neutral foods.

Vegetables are a treasure house of vitamins and minerals, which contain a lot of elements such as calcium, potassium, sodium and magnesium. They exist in blood in the form of calcium carbonate and potassium sulfate to neutralize acidic substances in blood, regulate the metabolic function of blood and sweat glands, and strengthen skin nutrition.

Therefore, in order to moisturize the skin and make the face moist and smooth, we should eat more vegetables.
