There are many medium and weak bases. Basically, vegetables and fruits are alkaline, such as beans, tomatoes, spinach (very good for people's health), cabbage, potatoes, apples, bananas and strawberries.

Now many people are sub-healthy, so they should eat less acidic food, mainly meat, egg yolk, cheese, cream and so on.

I have recently studied health care after work, hehe, I wish you happiness and health.
