During the day we carry out many activities such as study, work, walk, run, jump. They all energy spent, that’s why we need to feed the body to function properly. Remember that food gives us energy, allow us to grow, increase our resistance to disease and give us the elements that our body needs to stay healthy.

After eating breakfast, lunch or any meal, spend some time in which the body makes digestion of the food. In this way food is processed in the necessary nutrients for the body to perform vital functions. But not every food we eat has a nutritional value, so it becomes necessary to exchange ideas about the nutritional value of foods and their roles in the body.

This is determined by the amount of nutrients that contribute to our body when it is consumed. These nutrients may be fat, carbohydrates, proteins, vitamins and minerals. The nutritional value is different in each food group, some foods have more or less nutrients than others. That’s why, for sorting should be taken into account the nutrient that most abounds in its composition.

The food also plays different roles in the body.

According to its role foods are classified as:

Energy

Repair

Regulators

Food energy : There are those who give us the energy required to perform various activities and also provide us with heat. The energy value or caloric value of a food will depend on the amount of energy that can provide burned in the presence of oxygen. This value is measured in calories is the amount of heat needed to increase by one degree the temperature of a gram of water. These foods are carbs that are found in corn, rice, bananas, vegetables, sweets, etc.. and lipids that are derived from oil, sausages, butter, etc..

Food repairers : Not all the food we eat is burned to produce energy. There is a type of food called repairers, plastics or builders they help us to grow rebuild and repair the damaged tissues of our body and facilitate chemical reactions necessary for the maintenance of life. The most important foods in this group are proteins that are found in all kinds of meats, fish, eggs, milk, nuts, grains, legumes, whole grains, etc..

Food regulators : These foods contain substances that use the body in very small quantities to digest food properly and help coordinate the functioning of the body. It is believed that these foods do not add calories to the body. In this group are vitamins A, C, D, E, K and B complex to be found in vegetables, vegetables, fruits, milk, eggs, fish, etc.. Also includes minerals such as iron, phosphorus, Calcium, zinc, iodine, etc.., and water.

As, we have seen so far, the person with diabetes can and should make a free diet plan, once received adequate training, so you can share some daily food for others to make the appropriate menu to its potential or imperatives. This is what we call the strategy of equivalence or exchanges, which is planning a daily quantities of food “generic”, representatives of the group, chosen as the calories and caloric pre-sharing, and attach a few tables to replace those equivalences generics, for other foods that, combined, would allow the drafting of a menu according to taste patient, and possibilities.

This dietary planning system is the result of work and consensus of several years, various medical and scientific equipment and Societies, in order to achieve a unified system of reference accepted by all, similarly to other countries so that serve as a basis for any publication, and for all diabetics of all communities and cities have diets, more or less personalized, with a unique system developed and approved, to avoid confusion .

The equivalence can be expressed in units of exchange or in grams. As den listings replacement:

Grams, we have subsistence allowance equivalent.

Units exchange or rations, we allowances for units of exchange or rationing  .

For exchanges and equivalents are grouped foods:

1) milk

2) food protein

3) hydrocarbon food: cereals and pulses and tubers

4) fruit

5) vegetables

6) fats, equivalent to 7 groups food diet balanced, as we saw at the beginning, except that unifying groups 3 and 6 in one, the group called hydrocarbons or Starchy.

Concept of (ration)

An exchange is the amount of food that contains 10 grams of one of the energy nutrients: protein, fats or carbohydrates.

1 exchanges CR = 10 grams of carbohydrates or

10 SW of proteins or

10 GR fat

Diabetes education in this same concept has been called long intake, but we prefer to replace it with the term exchange, because ration is also a culinary term or trade shows that the normal portion of a food that usually consume an adult, so as confusing.

Diet exchange: the possibility of eating a personalized and tailor.
