Balanced Diet

A balanced diet includes eating enough food, strictly dosed and in the right proportions of protein, fats and carbohydrates. The diet provides the body with all the necessary nutrients for growth, regeneration processes and, in theory, allows to get rid of a few extra pounds.

A balanced diet means getting the right types, and amounts of food and drinks to supply nutrition and energy for maintenance of organs, tissues and cells of the body, as well as to support the growth and development. A well balanced diet provides enough energy and nutrition for optimal growth and development. A balanced diet is one that contains all the nutrients needed to achieve optimal nutritional status (Sperduto, 1994, 1413).

Components of Balanced Diet

A balanced diet must contain essential minerals, vitamins, pectin - that is, all the components that allow the body to function normally. The proportions of the main components of the diet should be as follows: 15% protein, fat 30%, including no less than 3% should be unsaturated fatty acids, carbohydrates, 50-60%, including about 10% sugar. The feed covers the purposes to contribute an amount of energy nutrients (calories) that are sufficient to carry out metabolic processes and physical work necessary. Also, to provide sufficient nutrients plastic and regulatory functions (proteins, minerals and vitamins).


The quantities of each of nutrient are balanced against each other. The group of experts established the following proportions:

Protein should make up between 12-15% of total caloric intake, never being less than the amount of protein intake to 0.75 g / day and high biological value.

Carbohydrates should represent at least 50-60% of total caloric intake.

Lipid will account for 30-35% of total calories consumed (Glewwe , 2001, 345).

Dietary Reference Values (DRV)

Balanced diet is one that ensures a demand-supply of energy and nutrients for health and wellbeing. Dietary reference values (DRV) means all nutrient recommendations and reference values for the absorption of nutrients such as reference intakes for the population, the average nutrient requirements, the adequate intake level and the lower recording limit. Dietary Reference Values (DRV) indicates the amount of an individual nutrient that people need for good health according to age and sex. The Dietary reference values can, for example, as a basis for reference values for food labeling and the creation of food-based dietary guidelines (Food-Based Dietary Guidelines - FBDGs) are used. Using such nutritional guidelines can be implemented; the recommended nutrient intakes into practical recommendations for nutrition and the consumption of certain foods that provide consumers with valuable guidance and help them eat healthily (Mauro, 2008, 73).

Reference Nutrient Intake (RNI)

The RNI value is the amount of a nutrient intake per day, which meets the needs of all members of a population group to which it is not a minimum value. In other words, it is the estimated amount of a nutrient required to meet the needs of most of the group implementing the estimate is not a minimum dose.

It is an estimated of the dietary Reference Value (DRV) to maintain good ...
