May 31st, 2008 -- Posted in Carbohydrates, Cereals, Grains & Derivates, Nutrients, Nuts, Protein | No Comments »

There is no food that contains all the essential nutrients. For example, wheat flour and comprehensive lack of vitamins A, B12, C and D, and contain very little calcium. However possess a lot of dietary fiber. The calf contains very little or nothing of calcium, vitamins A, C and D and fiber but possesses iron and vitamin B12. In making both food groups, we received the elements from both, but we need to add citrus salads or make vitamin C, and milk or cheese containing vitamin D and calcium. So, combining the completion of various food groups to form a balanced diet.

According to the role in the body, foods are classified as:

Foods rich in plastic or trainers substances essential for the formation and maintenance of our structure: protein and calcium.

Food energy-rich substances that provide energy to the body: fat and carbohydrates.

Food regulators rich in vitamins and minerals essential for occurring chemical reactions of metabolism.

From a practical point of view, the classification of functional foods is not possible to establish guidelines or patterns of simple food for the general population. It is necessary to group the foods they share responsibilities and provide similar amounts of nutrients. In Spain, since the education programmed in Food and Nutrition (EDALNU) in the sixties, was adopted a model for classifying foods based on 7 groups.

Group 1: milk and dairy products: cheeses and yogurt.

Group 2: meat, eggs and fish.

Group 3: potatoes, vegetables and nuts.

Group 4: vegetables.

Group 5: fruit.

Group 6: bread, pasta, cereal and sugar.

Group 7: fats, oils and butter.

A balanced diet should provide:

4-6 servings per day of food groups 3 and 6: bread, pasta, cereals, potatoes, vegetables

3-4 servings per day Group 4: vegetables

2-3 servings per day of group 5: fruit

2-3 servings per day of Group 1: Milk

2-4 servings per day in Group 2: meat, eggs, fish

40-60 grams per day of fat

We must not take the same daily rations of food each group but there are several those for two reasons:

1. Nutrients are characteristic of each group vary widely among the same foods.

2. The natural toxins and pollutants are distributed in all groups. The more varied the food is, the lower the possibility of taking in harmful quantities.
