The essential amino acids are 14 kinds of vitamins, including fat-soluble vitamin A, vitamin D, vitamin E, vitamin K, and water-soluble vitamins B and C. There are seven kinds of macronutrients in minerals, such as potassium, sodium, chlorine, calcium, phosphorus, magnesium and sulfur, and 14 kinds of micronutrients, so there are about 40 kinds of essential nutrients for human body.
Extended data:
Besides vitamins and minerals, there are also essential amino acids and essential fatty acids. Some nutrients needed by human life activities are digested and decomposed into small molecular monomers in the body through absorbed nutrients, and then transformed and synthesized into biochemical substances needed by the human body.
However, there are some small molecular substances that the human body cannot synthesize, or the synthesis speed is too slow to meet the needs of the body and must be supplied by the outside world. Such small molecular substances are called "essential nutrients".
