Difference between food and nutrition

The food it is the action of living organisms to ingest any type of food, solid or liquid, to satisfy their biological needs.

The nutrition it is the obtaining and taking advantage of those components or nutrients present in food, and which are vital for the growth and/or life of the organism.

The difference between food and nutrition is that the first action refers to the actions involved in obtaining and choosing foodand the second involves the food processing and digestion inside the organism.

Food begets a process of nutrition, and nutrition depends on food to do so.

definition It is the obtaining and selection of food that will be ingested. It is the process of breaking down the food consumed to obtain its nutrients.
  • It depends on the geographical environment.

What is nutrition?

Food is the obtaining, selecting and preparing food in order to ingest them. In the case of human beings, food may be natural or man-made, solid or liquid, may or may not require prior processing (cleaning, boiling, cooking, etc.).

Eating is an act that depends on many factors:

  • learning,
  • the geographical environment,
  • the social group,
  • the habits,
  • socioeconomic factors,
  • personal preferences,
  • health conditions, etc.

Hence, although it is a universal act, it is not done in the same way all over the world, not even within the same social group.

On the other hand, eating is an individual and voluntary act, since everyone can decide how and when to eat.

It is important to note that the terms diet and nutrition they refer to the act of choosing the foods to be consumed. When food selection must be specific (whether due to illness, as part of a weight loss program, food allergies, etc.), then it is a food plan

Type of food

Since obtaining and selecting food depends on multiple factors, the types of food can be very varied. However, there are general classifications that allow identifying the most popular types of food.

Balanced diet

balanced diet

It includes a selection of foods from all food groups (milk, meat, vegetables, plants, fruit, cereals and fats) in moderate amounts, which must be present at all meals.

Vegetarian food

vegetarian food

It is a type of diet based on the consumption of vegetables, legumes, cereals, fruits and fats of non-animal origin. Within vegetarianism there are some sub-classifications, such as:

  • Ovolactovegetarianism: includes eggs and dairy.
  • lactovegetarianism: includes milk and other dairy products.
  • veganism: excludes any food of animal origin. More than a type of food, it is a practice where the consumption and use of products made from animals is avoided.

Mediterranean food

Mediteranean diet

Also known as the “Mediterranean diet”, it is a food selection based on the eating habits of the inhabitants of the Mediterranean region (Spain, Portugal, Italy, France, Greece, Morocco, Cyprus and Croatia).

This type of diet includes large amounts of vegetables, grains, fruits, legumes, and monounsaturated fats (such as found in blue fish and nuts), while consumption of red meat is low.

What is nutrition?

Nutrition is the process by which living organisms transform food into energy and matter, to be able to fulfill their vital functions. This process takes place after the food is cooked to obtain the nutrients they need.

Nutrition includes the absorption of food, digestion, metabolism and excretion of waste or elements that are not nutritional or that were already used by the organism.

In order for an organism to be able to nourish itself, in the sense that it can obtain the energy it needs, it is necessary that the selection of food is appropriate for its needs, therefore, the type of food directly influences the quality of nutrition,

However, nutrition is one biological, physiological and involuntary processtherefore, it will take place once the food is ingested and regardless of its type, quality or quantity.

Type of nutrition

According to their type of nutrition, living things can be autotrophs or heterotrophs, depending on the primary food source.

Autotrophic nutrition

autotrophic nutrition

It is the absorption of nutrients from inorganic substances. Autotrophs produce their own food from carbon dioxide, which they obtain in one of these processes:

  • photosynthesis: is the obtaining of organic matter from light energy. Most plants are photosynthetic autotrophs.
  • chemosynthesis: in this case, the nutrients are obtained after an oxidation-reduction process of inorganic components. Bacteria, for example, are chemosynthetic autotrophs.

Heterotrophic nutrition

heterotrophic nutrition

It is the process of synthesizing nutrients from organic substances. Heterotrophs cannot produce their own food, so they depend on another organism for nourishment, either autotroph or heterotroph.

Humans, animals, fungi and some microorganisms are heterotrophs. And at the same time, they are subclassified into three types.

  • herbivores: refers to living things that feed only on plants. In this case, the digestive system cannot process another type of organic matter. They depend directly on autotrophs, which provide them with food by converting inorganic matter into organic matter. The rabbit, horse and elephant are examples of herbivorous animals.
  • carnivores: they are the organisms that feed only on meat. To be able to do this, they evolved to develop teeth, which are what allow them to obtain and grind food. the coyote, dolphin and crocodile are some carnivorous animals.
  • omnivores: in this case, the food source is herbivore and carnivore. They are not adapted to feed on plants or meat exclusively, so they combine the two sources. Mammals (including humans), birds, and some species of fish and reptiles are omnivores.
