Why Is Nutrition Important?


Why Is Nutrition Important? – A Short Read For Beginners

This blog post, “Why is nutrition important?” was written for you. Whether you are a a high schooler, college student, or nutritionist – I hope that you will receive some benefit after reading this.

Nutrition is the set of actions and processes by which a cell or a living being absorbs and transforms food to ensure its survival. It is the set of physiological functions that ensure the processes of assimilation and dissimilation. Biological nutrition is the set of processes of food, digestion, respiration, circulation and excretion. Nutrients are molecules produced during the digestion of food consumed Proteins, lipids and carbohydrates are the three major groups of nutrients that allow the body to build itself, to renew itself, and to provide the energy necessary for metabolism . However, they can be divided into two groups: essential nutrients and non-essential nutrients. Indeed, proteins and lipids are said to be essential because our body is unable to manufacture them and they must therefore be transported through food, unlike carbohydrates which can be synthesized from other nutrients.


  • Proteins are made up of amino acids which, once released during digestion, will be used by the body to produce its own proteins. The latter enter into the composition of the human body, in particular the muscles, the bones, the skin, the hair or the nails. In addition, they are essential for certain physiological processes such as the immune response (antibodies) or the production of hormones. They are also the body’s only source of nitrogen.


  • Lipids are the most energetic nutrients. They are the constituents of the membrane of our cells (bilayer of phospholipids) and therefore ensure their proper functioning, and that of the organs. We can add to this that lipids have an essential role in the transport of certain proteins and hormones in the blood, as well as a good number of vitamins. For hormones, they not only transport them, but they also participate in the development of some of them


  • Carbohydrates, unlike proteins and fats, are not essential, and can be produced from other nutrients. Carbohydrates are used in the form of glucose. This glucose will be used by all cells, whether muscle or nerve, including brain cells. It can also be, to a lesser extent, transformed into glycogen to serve as an instant energy reserve for the muscles.


  • Water is a reference polar solvent that dissolves many compounds such as salt and sugar most foods naturally contain water, it is an essential nutrient that allows many reactions to take place, so it is essential for the functioning of living organisms. It also allows the transport of nutrients and the hydration of the body’s tissues, the human body contains on average 60% water, Humans are able to live without food for several weeks but cannot live without water for more than a few days.

A Balanced Diet

A balanced diet is a diet that is sufficiently varied and well distributed throughout the day. It is the one that provides the body with the calories necessary for the functioning of the human body. Apart from breast milk, no other food manages to bring together all the nutrients necessary for the proper functioning of the human body: proteins, lipids, carbohydrates, vitamins, minerals, trace elements, fibers. This is why a balanced diet (varied and diversified) is essential to cover all needs and keep the body in shape.

Thus, a balanced diet requires…

  • The consumption of fruits and vegetables
  • The choice of fats
  • A varied and diversified diet
  • Moderate consumption of industrial sugars
  • Constant hydration
  • A balanced plate

A balanced plate is one that contains protein, vegetables (2/3 of the meal) and starches (1/3 of the meal). Proteins such as meat, fish, eggs, cheese; raw or cooked vegetables and starches such as pasta, rice, potato, and cereals.

Procedure for a healthy diet

A balanced diet can help prevent health problems. Therefore, it is important to pay attention to a wholesome, healthy diet.

  • Varied, predominantly plant-based foods
  • Five servings of vegetables and fruits a day
  • Low salt and sugar
  • Animal-based fats (no trans-fats)
  • Whole grains every day
  • No more than 600 grams of meat per week
  • Fish once or twice a week
  • About 1.5 liters of water every day
  • Gentle preparation, time and enjoyment when eating and drinking

What is Food? | Why Is Nutrition Important

Food is the ingestion of food by organisms to obtain the necessary nutrients and energy to achieve balanced development. Food is the action and effect of eating, that is, a process by which living things consume different types of food to obtain from them the nutrients necessary to survive and perform all the necessary activities day by day. Depending on the mode of feeding, living things can be either autotrophs or heterotrophs. They are autotrophic when they themselves manufacture the food they consume, this is the case of plants which, from inorganic elements such as energy from the sun, water and mineral substances (carbon dioxide, mineral salts, etc.), manage to make their own organic matter through photosynthesis. They are then called primary producers.

  • Heterotrophs are living beings that feed by ingesting other living beings. Thus, heterotrophs are entirely dependent on other beings that they consume to manufacture their own substances.

A Varied Diet

Foods are divided into 5 main categories: meat, fish, eggs; dairy products; cereal and starch products; vegetables; fruits.

A diversified diet must include at least one food from each category every day, respecting a few simple rules:

  • Consume at least 2-5 servings of fruits and vegetables per day.
  • Limit the consumption of fats, especially saturated fats (pastries, pastries, cold meats, butter, sauces, cheeses, whole milk, fatty meats, etc.).
  • Increase the consumption of carbohydrates, in the form of whole grains (whole meal or cereal bread, rice, pasta, whole meal, etc.).
  • Consume meat, fish and other seafood products or eggs 1 to 2 times a day, favoring lean meats and fish consumption.
  • Limit the consumption of pastries, sweets and sugary drinks.
  • Limit wine (if not formally advised against) to one glass per day
  • Water is the only essential drink, to be consumed without moderation: at least a liter and a half a day, as it is or in the form of hot drinks
