What you we need to follow a balanced diet?

I always think it's very important to eat in a balanced way and especially eating the things our body needs for proper functioning moderately, without excess. Good nutrition is essential as we are what we eat.

In the food pyramid there are five levels which in turn contain seven groups which shows the variety, number and proportion of foods that should be consumed by individuals in order that their body performs all its functions and stay in good shape .

In this sense, the groups could be the following:

•       First:  milk and derivatives.
•        Second: Meat, fish and eggs.
•         Third, potatoes, legumes and nuts.
•        Fourth: Vegetables.
•               Fifth: Fruits.
•        Sixth: bread, pasta, cereals and sugar.
•         Seventh: Fats, oils and butter.

Junk food tends to be high in fat, salt and calories and low in dietary fiber. These dietary factors can lead to health problems

Studies in the different universities, in February 2006 it is estimated that 66 percent of people consume junk food  daily, the daily consumption of sugar, fat and other substances that contribute to overweight. This type of food is detrimental to health and makes us gain an excessive way for our weight.

One of the most common myth is: "Potatoes are fattening"; The truth is that they have 75-80% water, and the rest is carbohydrate which contributes only 85 kcal. per 100 g. and finally the other common myth of all is: "The bread fattening"; The caloric content of 100 g of white bread is very small: about 250 kcal. But bread doesn't fat because the accompanied food is that has high fat.

In conclusion it is always necessary to control all the food we eat to keep fit and stay healthy. What do you think?
