What are the main nutrients required by the human body?

There are seven main categories of nutrients that the human body needs: carbohydrates, fats, proteins, vitamins, inorganic salts, water, and dietary fiber. The seven nutrients in the human body can play a physiological role in three ways:

One is as an energy substance, which supplies the energy (mainly proteins, carbohydrates and fats) needed by the human body; The second is as a "building" material for the human body. The energy needed by the human body is mainly protein: the third is used as a regulating substance to regulate the physiological functions of the human body, mainly vitamins, inorganic salts and cellulose.

These nutrients are distributed in a variety of foods and can be obtained as long as you can eat widely. Elements: iron, zinc, selenium, iodine, copper, manganese, chromium, fluorine, molybdenum, cobalt, nickel, tin, silicon, vanadium In addition, there is also information that strontium, arsenic and boron have the ability of various trace elements and supplementary nutrients to penetrate into cells in humans or animals, so they play a role in health and fitness.

The nutrients that the body needs include proteins, fats, carbohydrates, vitamins, inorganic salts, and water.

The human body needs more than 40 kinds of nutrients, of which six groups of substances are the most important, known as the six major nutrients, namely proteins, lipids, carbohydrates, vitamins, inorganic salts (minerals), and water. Among them, carbohydrates, fats and proteins are present and consumed in large amounts in food, which are called macronutrients or macronutrients, while vitamins and minerals only need a small amount in a balanced diet, so they are called micronutrients. Many scholars have also classified dietary fiber as a nutrient and has become a Category 7 nutrient.

Essential nutrients often refer to nutrients that are necessary for human growth and development, and cannot be synthesized or not synthesized in the body. In addition to vitamins and minerals, there are also essential amino acids and essential fatty acids. Some of the nutrients required for human life activities are digested and decomposed into small molecular monomers in the body through the absorbed nutrients, and then transformed and synthesized into biochemical substances required by the human body.

However, there are some small molecule 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 molecule substances are called "essential nutrients".

Among the essential minerals for the human body, there are essential macroelements such as calcium, phosphorus, sodium, potassium, magnesium, chlorine, sulfur and trace elements such as iron, iodine, zinc, selenium, copper, chromium, molybdenum, and cobalt. Vitamins can be divided into fat-soluble vitamins and water-soluble vitamins. Vitamin A, vitamin D, vitamin E, vitamin K are fat-soluble vitamins, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C, pantothenic acid, folic acid, niacin, choline, and biotin are water-soluble vitamins.

In addition to these nutrients, water is also essential for the human body. In addition, dietary ingredients such as dietary fiber and other phytochemicals are necessary for maintaining health.

There are many nutrients that the human body needs, such as carbohydrates, proteins, vitamins, oils, minerals, water, dietary fiber, etc. These nutrients are important for maintaining the normal functioning of the human body, and a lack of any one of these nutrients can lead to the occurrence of diseases. Now many people know that to increase nutrition, when it comes to what nutrients the human body needs, not everyone knows, in fact, the nutrients required by the human body are generally divided into six categories:

Proteins, fats, carbohydrates, vitamins, minerals and water. These six categories of nutrients, proteins, fats, and carbohydrates are functional substances that are essential for the human body.

What are the essential nutrients for the human body? How much you need to consume per day.

Carbohydrates (sugars), fats, proteins, vitamins, water, and inorganic salts (minerals) are the six major nutrients that the body needs.

1. Carbohydrates.

It is the main source of energy, and cells are able to convert carbohydrates into glucose. Be aware that when we eat fruit, we are getting our daily vitamins, minerals, fiber, and water needs. Carbohydrates are found in grains such as fruits, vegetables, sugar, flour, milk, wheat, corn, oats, and rice, as well as nuts and grains.

2. Fat. It can provide us with a lot of energy, including fatty acids needed to coordinate the body's activities, and it also transports some fat-soluble vitamins to various parts of the body. Saturated fats are found in foods such as beef, pork, chicken, fish, dairy products, eggs, and tropical cocoa butter, and unsaturated fats can be found in pure olive oil, vegetable oils, peanuts, and avocados.

3. Protein.

Modern nutritionists believe that foods containing animal protein are more beneficial to health. The main animal protein comes from poultry and fish.
