Meaning of Nutrient

What is Nutrient:

As a nutrient it is understood as everything that nourishes or feeds in order to guarantee the conservation and development of an organism. The word nutrient is of Latin origin and derives from the participle of the verb otter, nutris whose meaning is “nourish” or “feed”.

Nutrients originate from outside the cell that it needs to fulfill its vital functions. Nutrients are taken or absorbed by the cell and transformed through a metabolic process of biosynthesis called anabolism or, degraded to obtain other molecules.

for ecology the basic nutrients are: oxygen, water and essential minerals for the life of plants and through photosynthesis they incorporate living matter constituting the base of the food chain since these plants will serve as food for animals.

By virtue of the photosynthetic incapacity on the part of living beings such as animals and others, the substances that food possesses are essential for life, the preservation of health in living beings. By virtue of it, Nutrients are organic and inorganic chemical compounds contained in food and are necessary for the metabolism of a living being.. In reference to this point, foods are classified according to their chemical nature: proteins, carbohydrates, vitamins, lipids and mineral salts.

For a better understanding of the above, organic nutrients They are characterized because in their composition they contain large amounts of carbons, the main organic nutrients are: sugars, fats and proteins. At the same time, inorganic nutrients They do not have carbons, such as: water, mineral salts.

Nutrients are classified depending on their functions and the amount needed by cells, therefore nutrients can be essential and non-essential. essential nutrients As their name says, they are essential for the organism and cannot be synthesized, they are obtained from the environment and, non-essential nutrients they are not vital for the organism and can be synthesized through precursor molecules, generally essential nutrients.

Likewise, depending on the amount needed by plants and living organisms, they are grouped into: macronutrients needed in large quantities and participate as substrates in metabolic processes, in turn, the micronutrients It is not required in large quantities and participate as regulators of energy processes.

It is of the utmost importance that the diet of a living being be balanced and contain a combination of all foods, it is what is known as a balanced diet since each nutrient has an essential function on the health and organism of a living being.

energetic nutrients

Food is vital to provide the body with the energy it requires to carry out its functions, which is known as energy nutrients. The energy is found in the form of calories in the nutrients of the food, essentially in the carbohydrates found in potatoes, legumes, cereals, bread, pasta, in the fats that are observed in foods such as: butter, oils , is also observed in meat, fish, among others. Therefore, the higher the intake of these nutrients, the higher the energy value of the diet.

Regulatory nutrients

In addition to the above, there is regulatory nutrients They are characterized by controlling the chemical reactions of metabolism such as: blood circulation, digestion, proper functioning of the intestines and strengthen the immune system. The regulatory nutrients are: vitamins, some foods rich in vitamins are: carrot, tomato, broccoli, lettuce, banana, orange, grape, etc., and certain minerals such as: sodium, potassium.

structural nutrients

structural nutrients They help in the formation of the structure and growth of the organism, some nutrients of this type are: proteins, carbohydrates, minerals such as: calcium, phosphorus, among others.
