It refers to the group of foods that make up the nutritional behavior of living beings.
The eating habits of living beings will depend on our way of life, habitat and other factors.
A diet does not translate into eating little, it is a diet. There are diets to lower, raise or maintain weight and there are also to improve our health.
The feeding of human beings is governed by social, biological, psychological, hormonal, economic, political and cultural factors.
Geography and weather conditions also restrict the availability of food. As well as customs, tradition, personal factors, preferences, advertising influence, eating disorders among others, are also conditioning factors of the food we consume.

How much food do I need to have a healthy diet?A healthy diet should provide us with the right amount of energy (calories), food and beverages to maintain energy balance.
The energy balance is where the calories taken from the diet are equal to the calories used by the body. We need these calories to carry out daily tasks, such as walking and moving, but also for all body functions that we may not even think about.
Influence of diet in our lifeProcesses like breathing, pumping blood around the body and thinking also require calories. Therefore, foods and beverages provide the calories we need for our daily lives, but consuming more calories than we need over a period of time will cause weight gain.
This is because the extra calories we consume but do not use will be stored as fat.
More than 50% of adults in the world are overweight or obese. There is also a great concern about childhood obesity, where 1 in 3 children between 4 and 5 years old and 1 in 5 children between 10 and 11 years old are overweight or obese.
Being overweight as a child increases the risk of developing type 2 diabetes, heart disease and some cancers in adulthood.
Therefore, maintaining a healthy weight is really important for health. The amount of energy you need from food and beverages depends on many different things, such as how active you are.
But, on average, eating only as many calories as you need will help you maintain a healthy weight. However, the foods and drinks you choose should be the right ones and in the right proportions to stay healthy.
