Meaning of Food
What is Food:
A food is a substance that has the property of giving a certain organism the nutrients and energy necessary for it to fulfill its basic functions.
All living things require food: people, animals and plants. However, each of the living things requires different types of food. Plants, for example, feed on sunlight, through the process known as photosynthesis.
Because the human body requires a great complexity of nutritional elements, such as proteins, minerals, vitamins, etc., the foods that humans require are of very varied types, since they collaborate in different processes.
Types of food
Food suitable for human consumption is classified by group:
- Group 1: milk and its derivatives (cheese, yogurt, whey, cream);
- Group 2: meat, eggs and fish;
- Group 3: legumes, tubers and nuts;
- Group 4: vegetables and greens;
- Group 5: fruits;
- Group 6: bread, cereals, pasta and sugar;
- Group 7: fats, oil and butters.
It is worth saying that no diet is complete without adequate hydration. Therefore, water is a fundamental component of a good diet.
Types of nutrients in foods
Food has a set of nutrients that are essential for health. Among them we can mention:
- Macronutrients, among which are proteins, carbohydrates, and fats and lipids.
- Micronutrients: minerals, vitamins, mineral salts and inorganic compounds.

In the case of humans, food is not only responsible for nutrition, but also affects the psychological and social development of individuals. Let's look at those functions separately:
Nutrition: the first function of food is to nourish the body from a physiological point of view. Adequate nutrition allows the development of tissues and the capture of energy for the functioning of the body.
- Psychological development: food has the power to influence the development of cognitive and emotional processes. Therefore, proper nutrition is essential for the development of intelligence, as well as motor skills. In addition, since eating is a pleasure that stimulates smell and taste, it brings satisfaction.
- Social development: food is usually shared in community. This makes the ties become closer and quality affective relationships are established.
