7 major nutrients for the human body

Everyone knows that nutrition is indispensable for the human body, because only when nutrition is sufficient can a person have better energy to do other things. There are many nutrients in the human body, and each nutrient plays a different role in the human body. However, some people are not very familiar with these nutrients. Next, I will introduce to you the seven major nutrients in the human body.

1. Protein

Protein is the material basis of all life. It is constantly synthesized and decomposed in the body. It is an important component for the formation, renewal, and repair of human tissues and cells. It participates in the regulation of material metabolism and physiological functions, ensures the growth, development, reproduction, inheritance and energy supply of the body.

2. Lipids

Fat is one of the important sources of energy, assists in the absorption of fat-soluble vitamins, protects and stabilizes internal organs, prevents heat loss and maintains body temperature.

3. Sugar (Carbohydrates)

Carbohydrates are the main energy source for the human body. More than 70% of the energy required by the human body is provided by carbohydrates. It is also an important component of tissues and cells.

4. Water

Water is necessary for maintaining life and is an important component of body fluids in the human body, accounting for about 60% of body weight. It has the functions of regulating body temperature, transporting substances, promoting chemical synthesis in the body, and secreting water to lubricate the skin and organs.

5. Vitamins

Vitamins are substances necessary for maintaining human health. Although the required amount is small, they cannot be synthesized in the body or the amount synthesized is insufficient, so they must be continuously taken in from food. Vitamins are divided into two categories: fat-soluble (vitamins A, D, E, K) and water-soluble (vitamins other than vitamins A, D, E, K). They are essential for maintaining normal growth and development and regulating physiological functions of the human body.

6. Minerals

Minerals are important components of bones, teeth and certain human tissues. They can activate hormones and maintain major enzyme systems, and play a very important role in regulating physiological functions.

7. Cellulose

Fiber refers to the components in plant foods that cannot be digested and absorbed and is an indispensable element for maintaining health. It can soften intestinal contents, stimulate gastric wall peristalsis, assist defecation, and reduce the absorption of cholesterol and glucose in the blood.

The above are the seven essential nutrients for the human body. These seven nutrients are all present in food. Therefore, as long as you maintain healthy eating habits, are not picky about food and try to diversify your food, you can basically ensure the normal intake of the seven nutrients.
