What are the seven major nutrients of the human body and what role do they play in the human body?

The six major nutrients are: fats, proteins, sugars, inorganic salts, vitamins, and water. Among them, sugars, fats, and proteins are metabolized in the human body to produce energy, so they are also known as energy-producing nutrients, and their main role is the composition of the body and providing energy.

Sugar, also known as carbohydrates, is the most important calorie in the human body**, and the decomposition and absorption of sugars will participate in many life activities; Fat is an important component of tissue cells, and it can provide twice as many calories as the same amount of protein or sugar.

In addition, fat is also an important form of energy storage in the human body; In addition to production capacity, protein is also a component of important parts of the human body.

Six Nutrients:The six major nutrients required by the human body usually include water, proteins, lipids, sugars, vitamins and minerals, among which proteins, lipids and sugars are the main substances that provide energy for the human body, and their effects are as follows:

1. Water: 70% of the body of a normal adult is water, which participates in the transportation and excretion of nutrients and wastes in the body, and plays a role in maintaining the stability of blood pressure and body temperature;

2. Protein: it can provide energy for the body, participate in the growth and development of tissues and organs, and promote wound healing;

3. Lipids: including fats, cholesterol, phospholipids, etc., in addition to supplying energy to the body, they also participate in the composition of various biofilms, protect internal organs, and maintain body temperature;

4. Sugars: 65% of the body's energy depends on sugars**;

5. Vitamins: usually participate in the mediation of the metabolism process of various substances in the human body in the form of coenzymes, and the more common vitamins are vitamin A, vitamin C, vitamin B, vitamin D, etc.;

6. Minerals: such as potassium, sodium, calcium, iron, zinc, etc., can maintain the balance of water and electrolytes in the body and maintain the stability of neuromuscular excitability.

There are more than six kinds of nutrients that the human body needs, but there are actually seven kinds of nutrients, which are proteins, fats, minerals, vitamins, carbohydrates, water, and glucose.

These nutrients play an important role in the metabolism of the human body and the operation of tissues and organs. If any of these nutrients are deficient, it can have adverse effects on the body.

Among them, protein is an important component of the human body, which not only participates in the structure of various tissues of the human body, but also has the function of repairing and renewing cells, and can improve the body's immunity and regulate the activities of the human body.

In addition, the oil in it is also a component of the human body, which can provide heat for the human body, and has the effect of thermal insulation, which can protect various organs in the body.

Water can help transport various nutrients needed by the human body, and has a variety of functions such as regulating body temperature and lubrication.

The six major nutrients in the human body: carbohydrates (sugars), oils, proteins, vitamins, water and inorganic salts (minerals) are the six major nutrients required by the human body. The main role is the composition of the body, providing energy.

Among them, macronutrients, in addition to fiber and water, mainly provide energy for the human body, measured in joules or calories. Each gram of carbohydrates or protein provides 4 kcal of energy and 9 kcal per gram of fat. Other nutrients, including fiber, water, minerals, and vitamins, do not provide energy but play an important role in the body's physiological activities.

1. Sugars. The main calorie** of the human body is to maintain normal nerve function; Promote the metabolism of fats and proteins in the body.

2. Grease. Oils and fats facilitate the absorption of fat-soluble vitamins; Maintain the normal physiological functions of the human body; Body surface fat can be insulated to reduce body heat loss.

3. Protein. Proteins are involved in the renewal and repair of tissues; Regulate the physiological activities of the human body and enhance resistance; Protein also produces energy for children's growth and development, so it is also a productive nutrient.

4. Vitamins. Vitamins are a class of compounds necessary for the maintenance of normal physiological functions of the human body, they do not provide energy, nor are they the structural components of the body, but they are absolutely indispensable in the diet, such as a long-term deficiency or insufficiency of a certain vitamin, namely.

Carbohydrates (sugars), fats, proteins, vitamins, water and inorganic salts (minerals) are the six major nutrients needed by the human body, and the first three produce energy after metabolism in the body, so they are also called energy-producing nutrients.

The main role is the composition of the body, providing energy. The six major nutrients come from eight major food groups: cereals, eggs, milk, roots, meat, fish, shrimp and shellfish, beans and dried fruits, vegetables and fruits.

Nutrition is the rational food that human beings need to repair old tissues, proliferate new tissues, produce energy, and maintain physiological activities. The substances in food that can be absorbed and utilized by the body are called nutrients. Sugars, fats, proteins, vitamins, water, and inorganic salts (dietary fiber is called"The seventh largest nutrient") is the six major nutrients required by the human body, and the first three are metabolized in the body to produce energy, so they are also called energy nutrients.
