Vitamins and minerals play a role in regulating bodily functions. Vitamins and minerals are micronutrients second only to carbohydrates, fats and proteins, which can promote the energy metabolism of carbohydrates, fats and proteins, and are indispensable substances for the human body.
Compared to the three major nutrients, vitamins and minerals are very limited in number, so they are called micronutrients.
There are 13 kinds of vitamins, which can promote the absorption and metabolism of other nutrients, and protect the healthy growth of blood vessels and tissues.
There are 17 types of minerals, which are important materials for various body tissues such as bones and blood, and play a role in regulating body functions.
Most vitamins and minerals cannot be synthesized in the body and can only be obtained from food. Different types of foods contain different amounts of vitamins and minerals. Insufficient or excessive intake can have adverse effects.
1. The definition of vitamins requires that vitamins meet the following four characteristics before they can be called essential vitamins:
Exogenous: the human body cannot be synthesized by itself, and needs to be supplemented by food;
Traceability: The amount required by the human body is very small, but it can play a huge role;
Modulative: Vitamins must be able to regulate the body's metabolism or energy transition;
Specificity: When a certain vitamin is deficient, the person will present a unique pathology.
According to these four characteristics, the human body needs a total of 13 vitamins, which are commonly referred to as 13 essential vitamins:
Vitamin A, Vitamin B, Vitamin C, Vitamin D, Vitamin E, Vitamin K, Vitamin H, Vitamin P, Vitamin PP, Vitamin M, Vitamin T, Vitamin U, Water-soluble vitamins.
2. Common points of vitamins:
Vitamins are found in food in the form of provitaminostats;
Vitamins are not components of the body's tissues and cells, and it does not produce energy, its role is mainly to participate in the regulation of the body's metabolism;
Most vitamins cannot be synthesized by the body or are not synthesized in sufficient quantities to meet the needs of the body, and must be obtained frequently through food;
The human body's need for vitamins is very small, and the daily requirement is often calculated in milligrams or micrograms, but once the deficiency occurs, it will trigger the corresponding vitamin deficiency and cause damage to human health.
3. Characteristics of minerals:
It cannot be synthesized in the body and must be ingested from food and drinking water;
uneven distribution of minerals in tissues and organs in the body;
There are synergistic or antagonistic effects between mineral elements;
The requirement of some minerals is very small, and the range of physiological requirements and toxic doses is narrow, and excessive intake can easily cause poisoning.
4. Uses of minerals:
As a component of cells and tissues.
as a component of functional proteins.
Maintain osmotic balance in the body.
as an activator of enzymes.
Involved in the transmission of nerve impulses.
Maintain pH balance in the body.

Sugars (especially glucose, which is the main energy supply substance in the organism, oxidizes quickly and provides more energy) and fats (the main energy storage substance in the organism, containing more "hydrogen" atoms, slower oxidation, but more energy), and under extreme conditions, proteins can also be converted into sugars through deamination to provide energy.
The energy supply sequence of the three is 1Sugars 2Fat 3. In addition, hormones (generally proteins, amino acid derivatives or sterols) have a regulatory effect on arthrionic activities, and antibodies (immunoglobulins) and immunoactive substances (such as lymphokines) produced during the action of the immune system can also regulate vital activities.

It should have at least 10 functions that regulate human body functions, such as immune regulation; Delay aging, improve memory, **, regulate blood lipids, regulate blood sugar and other functions.
1.Immunomodulatory function 2Anti-aging function 3Improves memory function 4Regulates blood lipid function.
5.Regulate blood sugar function 6Regulate blood pressure function 7Improves visual function 8Improves sleep function.
9.Promotes lead removal 10**Feature 11Cosmetic features 12Anti-fatigue function.
13.Anti-radiation function 14Anti-mutagenic function 15Hypoxia tolerance function 16Throat clearing and moisturizing function.
17.Improves gastrointestinal function 18Improves osteoporotic function 19Promotes growth and development.
20.Improves the function of nutritional anemia 21Protective function against chemical liver injury 22Promotes lactation.

The pH of a normal person is usually in between, and the range of variation is very small, because there are substances in the blood that act as a buffer for pH, which are composed of a weak acid and a corresponding strong alkaline salt, such as carbonic acid|Sodium bicarbonate, sodium monobasic phosphate|Sodium phosphate monobasic. They are acidic and alkaline buffers, which work together to regulate the body's acid-base balance!

There are two ways: neuromodulation and humoral modulation.
Neuromodulation is the most important mode of regulation in the human body, which is completed by nerve fibers emitting nerve impulses, and the effect is fast and precise, the scope is small, and the duration is short.
Fluid regulation is a more primitive way of regulation, mainly through the blood circulation to transport some chemicals to organs and tissues, so that tissue cells undergo functional changes, the effect is slow, long-lasting, and wide-ranging. The two modes of regulation are interconnected and coordinated, so that the human body becomes a unified whole to adapt to changes in the internal and external environment.

Vitamins and minerals. Bodily function refers to the life activities expressed by the whole human body and its various organs and systems. The whole composed of the physiological tissues of the spine or animal. Refers to the entire physiological tissue of a person or animal, and sometimes specifically the trunk and limbs. <

Vitamins and minerals are second only to carbohydrates.
Micronutrients for fats and proteins.
It can promote the energy metabolism of carbohydrates, fats and proteins, and is an indispensable substance for the human body. Vitamins and minerals are very limited in content compared to the three major nutrients, hence the names of micronutrients.

There are 17 kinds of minerals in the human body, which are important substances for bones, blood and other human tissues, and play a role in regulating body functions. Most vitamins and minerals are not homemade in the human body and can only be obtained from food.
Different foods contain different amounts of vitamins and minerals. Inadequate or excessive intake can have adverse effects.
I think this kind of thing varies from person to person. Some elderly people have drunk alcohol all their lives and suddenly let it stop all the functions of the body, which may make the body uncomfortable. Some older people don't drink alcohol when they're young. >>>More
In the normal metabolic process, the human body constantly produces acidic substances and alkaline substances, and also ingests acidic substances and alkaline substances from the daily diet, and acidic substances and alkaline substances are constantly changing in the human body, and this change must rely on the body's regulatory function to maintain relative balance. This equilibrium is the acid-base balance, and the range of the equilibrium is the pH value. This pH is best suited for cellular metabolism. >>>More
