According to the classification of chemical composition, food can be divided into acidic food and alkaline food. Acidic or alkaline foods are not divided by taste, but by the lowest oxidative metabolites in the body. Minerals in food are oxidized into potassium, sodium, calcium, magnesium cation and alkaline food. Conversely, chlorine, sulfur, phosphorus and ammonia with anions are called acidic foods. Generally speaking, meat, egg, grain, grease, liquor and so on belong to acid food, and vinegar, vegetable, fruit, beans, milk and so on basic food.
With the improvement of the living standard of modern people, people's diet and habits have changed very long. Alkaline food intake correspondingly decreases, and the consumption of acidic food is increasing. The large intake of meat dishes makes the blood sour. Improper diet is tie-in, make human body automatically adjust PH value of the function is more and more bad, cause physiological disorder of acid-base balance, blood acidic, this not only increases the calcium, magnesium, potassium and other basic elements of consumption, such as calcium, magnesium, potassium deficiency causes disease, also can increase the viscosity of blood, induce or aggravate atherosclerosis, hyperlipidemia, hyperglycemia and high uric acid hematic disease. The study found that people's IQ was linked to acid alkalinity in the body's brain fluid, with lower levels of acid (i.e., lower PH) and lower IQ. High alkalinity (PH) high IQ.
