Bioavailability refers to the extent to which nutrients in food are absorbed and utilized by the human body. Generally speaking, the higher the bioavailability, the better the human body can absorb and utilize the nutrients in food, which helps to improve the nutritional value of food and thus promote health.

Bioavailability is influenced by many factors, such as food types, processing methods, cooking methods and individual differences. For example, the bioavailability of protein is higher than that of carbohydrate and fat, and the bioavailability of animal protein is higher than that of plant protein. In addition, some nutritional supplements also need to consider bioavailability, because bioavailability will affect the effect of drugs.

It should be noted that the higher the bioavailability, the better. When choosing food or nutritional supplements, it is necessary to comprehensively consider factors such as bioavailability, such as balanced nutrition and appropriate intake. In addition, different people have different needs for different nutrients, so they need to choose appropriate food or nutritional supplements according to their personal situation.
