As we all know, water is neutral, with a PH of 7; If it is greater than 7, it is alkaline; If it is less than 7, it is acidic. Different from water, human body fluids are not neutral, but weakly alkaline, with a PH of 7.35 ~ 7.45 and an average of 7.4. The PH value of the baby's blood is around 7.4. Studies have shown that when the PH value of body fluid is 7.4, it is weakly alkaline and the body is the healthiest.
Formation and manifestation of acidic constitution
Eating too much acidic food for a long time, such as meat, fish and eggs, as well as less exercise, high mental stress, excessive psychological burden, bad habits (such as uncontrolled smoking and drinking), irregular life (especially staying up late) and environmental pollution (such as air, drinking water, crops, poultry and fish eggs) will make acidic substances stay in the body. When the accumulation of acidic substances in the human body exceeds the regulatory capacity of the human body, or the regulatory capacity of the acid-base balance of the human body is affected, the acid-base balance of the human body is broken, and the medical term is called acidic constitution. At this time, the body fluid was measured, and the PH value was above 7.34.
Performance of acidic constitution: In the early stage, people with acidic constitution often feel physical fatigue, memory loss, inattention, backache, gastrointestinal dysfunction, low immunity, and easy to get sick. When they go to the hospital for examination, they can't find obvious organic diseases, which is called sub-health state in medicine, that is, a state between health and disease. The further development of acidic constitution will lead to many diseases. Modern medical research has confirmed that hypertension, hyperlipidemia, cardiovascular diseases, diabetes, cancer, gout and osteoporosis common in the elderly are all related to acidic constitution.
The pH of food
The standard of dividing the acidity and alkalinity of food in nutrition is not based on the taste of food, but on whether the products of food decomposition in human body are acidic or alkaline. All foods with high content of chlorine, sulfur, phosphorus and other elements are called acidic foods, and the final products are acidic after metabolism in the body. All foods with high content of potassium, sodium, calcium, magnesium and other elements are alkaline after metabolism in the body. Such foods are called alkaline foods. Judging which foods are acidic and which foods are alkaline can be summarized as follows:
(1) All oils-animal oil and vegetable oil are acidic foods.
(2) Most cereals-barley, wheat, oats, corn, rice, bread and noodles are acidic foods. Only millet, chestnuts, sweet potatoes, potatoes and pumpkins are alkaline foods.
(3) Nuts, seeds and beans are mostly acidic foods, such as cashew nuts, walnuts, peanuts, sesame seeds and lentils. Only almonds, soybeans and pods are alkaline foods.
(4) All meat, viscera, eggs, seafood and shellfish are highly acidic foods.
(5) Almost all vegetables and fruits are alkaline foods. However, vegetables and fruits fermented or fried with salt or sugar will become acidic food.
Prevention and correction of acidic constitution
(1) A reasonable diet. Pay attention to the combination of meat and vegetables, the combination of thickness and the balanced intake of acid and alkali foods. Remember: balance is health.
(2) correct bad eating habits. Some people's drinking and smoking habits are more likely to cause acidic constitution.
(3) After strenuous exercise or excessive physical labor, muscle soreness will occur, which is due to the accumulation of lactic acid. At this time, you should eat more fruits and vegetables to help speed up the removal of acidic substances.
(4) Acidic constitution can lead to osteoporosis. When supplementing calcium, you should eat more alkaline foods to keep the body in a normal acid-base balance environment, which is conducive to the absorption of calcium and reduce the loss of calcium.
(5) Excessive intake of acidic food is prone to skin diseases, such as acne and freckles. Pay attention to the intake of alkaline food in your daily diet, and your skin will be healthy and beautiful.
(6) Drink plenty of water. Metabolic waste of human body is acidic, so we can increase the discharge of waste by drinking more boiled water or tea.
(7) When suffering from kidney calculi's disease or impaired renal function, special food may be needed to make urine acidic, alkaline or neutral. If you have hyperuricemia and gout, eat more alkaline food.
