Explanation of the term nutrient

Explanation of the term nutrient. Human beings must obtain the substances they need from food to survive and reproduce. These substances are collectively called nutrients and are what our body maintains. Key factors in health status, learn about the terminology of nutrients below. Explanation of the terminology of nutrients 1

Nutrients (nutrients) are substances that need to be taken in from the external environment to maintain all life activities and processes such as reproduction, growth, development, and survival of the body.

What substances do nutrients include?

Describe the substances included in nutrients and their sources.

There are seven main categories of nutrients needed by the human body, namely protein, lipids, sugars, vitamins, inorganic salts, dietary fiber and water. The source is as follows.

1. Protein: derived from animal foods and plant foods. The former's main food comes from fish, meat, poultry, eggs, milk, etc., while the latter's main food comes from rice, flour, corn, beans and soy products, potatoes, etc.

2. Lipids: derived from animal fats and vegetable fats. The former is mainly derived from various animal fats, fats and butter, while the latter is mainly derived from soybean oil, peanut oil, sesame oil, tea oil, cottonseed oil and coconut oil.

3. Carbohydrates: derived from cereals, potatoes, beans and other foods.

4. Vitamins: divided into two types: fat-soluble vitamins and water-soluble vitamins. The former is derived from animal foods and edible oils, while the latter is mainly derived from vegetables, fruits and cereals

5. Inorganic salts: divided into macroelements and trace elements, derived from various foods.

6. Dietary fiber: mainly derived from vegetables. Explanation of terminology of nutrients in fruits and whole grains 2

The seven nutrients necessary for the human body can be divided into seven categories:

1. Protein

Protein is the substance of all life. Foundation, it is continuously synthesized and decomposed in the body. It is an important component that constitutes, renews, and repairs 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. It assists in the absorption of fat-soluble vitamins, protects and fixes internal organs, prevents heat loss and maintains body temperature.

3. Sugar (carbohydrate)

Sugar is the main energy substance of the human body. More than 70% of the energy required by the human body is supplied by sugar. It is also an important component of tissues and cells. Composition.

4. Water

Water is necessary to maintain life. It 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, and promoting body chemistry. Synthesizes and secretes functions in the body to lubricate skin and organs.

5. Vitamins

Vitamins are substances necessary to maintain human health. Although they are required in small amounts, they must be synthesized because they cannot be synthesized in the body or are not synthesized in sufficient amounts. Consistently get it from food. Vitamins are divided into two categories: fat-soluble (vitamin ADEK) and water-soluble (other vitamins except vitamin ADEK). They are essential for maintaining normal growth and development of the human body and regulating physiological functions.

6. Minerals

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

7. Cellulose

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

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

What are the functions of nutrients

Nutrients can balance the nutrients in the body and maintain the balance of the body. The process of food being digested, absorbed, and excreted in the body is the substance in which food energy is converted into human vitality. "Nutrient" refers to the ingredients contained in food that are necessary to sustain life.

What are nutrients

Understanding what nutrients are is actually not complicated. The food that organisms need to survive is made up of a variety of chemical compounds. These compounds are also called nutrients and include fats, minerals, carbohydrates, vitamins and water. Essential nutrients allow organisms to survive and grow by stimulating and maintaining body processes. These compounds have multiple functions in the body. Some help repair and build body tissue, others produce heat and energy.

Macronutrients are nutrients that are needed in large amounts by organic matter, including fats, carbohydrates, water, and proteins, and most organisms depend on them for survival. Numerous elements are responsible for the daily functions of the body, such as building and repairing tissues, producing energy and heat, regulating hormones, and maintaining normal brain and nerve functions.

Salt, magnesium, calcium and potassium are also nutrients needed in large quantities and they are also known as macronutrients. These minerals ensure healthy teeth, bones and muscles. In addition, they have a role in balancing fluids in the body.

Trace elements are compounds that are only needed in small amounts. The trace elements needed by the human body include 13 vitamins and 12 minerals. They are vitamins A, B1, B2, B3, B5, B6, B7, B9, B12, C, D, E, and K, as well as potassium, sodium, calcium, phosphorus, chlorine, zinc, copper, magnesium, iodine, and manganese , molybdenum, selenium and other minerals.

Most of these vitamins and minerals can be obtained from the daily diet. While vitamin D is synthesized through sunlight exposure, vitamin K can be produced by microorganisms living in the gut. Lack of vitamins can lead to different diseases such as scurvy, rickets, or pellagra. But it should also be noted that excessive amounts of some nutrients can also cause damage to health.

Nutrients can also be determined based on whether they are necessary. Essential nutrients are not produced naturally in the human body and must be obtained through food. There are more than 40 types of nutrients in this category. Non-essential nutrients can be produced by the body itself, cholesterol being a prime example.

Phytonutrients are found only in plants. When consumed by humans, they act as antioxidants to protect cells from damage. Such nutrients include lycopene, zeaxanthin, beta-carotene, lutein, and various flavonoids.
