The pH of human body and the acidity of food are two completely different concepts. The pH of human body is regulated by lung, kidney and blood, not food, and food can't change the pH of human body. Long-term, large and single intake of a certain food will only increase the physical load and ultimately affect the acid-base metabolic balance.

There is a concept of stealing that alkaline food can fight cancer. Whether the food you eat is acidic or alkaline, the result is the same, first becoming "acidic" and then becoming "alkaline". Eating more fruits and vegetables is not because of their acidity and alkalinity, but because of their own nutritional value, which cannot shake the normal pH range of the human body.

Everyone should make their own health plan to prevent cancer according to different physical fitness, gender, age and other factors, and improve the "cancer probability" with lifestyle. Constantly change the recipes, diversify the varieties as much as possible, eat moderately fried and pickled foods and salt, and avoid eating processed meat products. Avoid alcohol, sugary drinks, nutrients and alcohol, and limit the intake of high-calorie foods.

Extended data:

The theory of acid-base constitution is a false proposition, but you can't ignore your constitution for health preservation. Constitution consists of congenital factors and acquired factors. Congenital factors come from parents and are inherited, and acquired factors are formed by living environment and living habits. In different environments, people's physique can also be adjusted accordingly.

For example, people's diet structure and living habits are different when they live in an oxygen-deficient environment on the plateau and in an environment with high humidity in the south. Traditional Chinese medicine divides constitution into nine types. For example, people with yang deficiency will have diarrhea if they eat sea cucumber, so they should eat warm food. People with yin deficiency eat nosebleeds, and eat food that nourishes yin. Therefore, physical fitness varies from person to person.
