Human beings must feed adequately to receive the food they eat, the necessary nutrients that allow them to maximize their vital functions and in this way, maintain adequate health. A healthy life is more than eating healthy, it’s worrying about your entire body, from the teeth to the toenails, that’s why you have to go to a dental clinic in Tijuana Mexico for dental implants.
In this sense, food and nutrition are two key and fundamental elements for the life cycle of humans and also, they are two related terms but differ in their implications for the individual.
In this article we will start with the definitions of food and nutrition to later, point out the basic differences that are derived from each one of them.
First of all, the word food comes from the Latin -alimentum- which refers to food and is known as the action by which the food necessary for its subsistence is provided or supplied to the organism. The feeding is a process that includes the selection of foods, the preparation or cooking and the ingestion of the same ones.
Therefore, it can be said that food is a voluntary and conscious process, since each person chooses what they want to eat. In the same way, this process is directly influenced by the place or region where the person lives, the culture and even religion, since for some religions the intake of certain foods such as meat is not allowed.
In this order of ideas, living beings need a balanced diet that includes water as a vital support, in addition to nutrients such as proteins, lipids, carbohydrates, vitamins and minerals essential for good health and life.
Therefore, there is a food pyramid that has changed over the years, which has the function of making known the nutrients in the food, dividing them by group and pointing out the importance of them for human life.
Nutrition is the biological process by which the organism assimilates the nutrients coming from the food that it ingests and that are necessary for the growth, functioning and maintenance of the vital functions of the organism. Adequate nutrition is one that covers the energy requirements through the metabolization of nutrients (carbohydrates, proteins and fats), vitamins, minerals and hydration, thanks to the consumption of water.
There are six classes of essential nutrients that the body needs for proper functioning, such as fats, vitamins, proteins, carbohydrates, water and minerals. An imbalance of these can cause serious health problems.
Similarly, nutrition is a process that consists of several stages, first of all is the food or ingestion that consists of the incorporation into the body of the food that is in the external environment. Later, there is the digestion that is the chemical transformation or splitting of the ingested materials. Then, there is the absorption, which consists of the passage of digested substances to the cells and finally, there is the elimination that consists in the excretion of substances not absorbed and unnecessary for life.
During all these stages, the transport process is also developed, which refers to the physical phenomenon of passage of food and nutrients from the mouth to the stomach and to the excretory and chemical apparatus, from the passage of nutrients to the body’s cells.
