Characteristics of a healthy diet
Food is the basis to achieve a good health. Food provides vitamins, minerals, proteins and other components needed for the body not to be sick. A healthy eating is that one that comes closer to a natural food ingestion, that's to say, the one that provides nutrients offered by nature in its most simple state.
Throughout history there has been a negative trend in eating habits. The first men ate fruits, vegetables and seeds collected from the wild. However, over time, there has been a change in this tendency.
Commercial reasons have replaced common sense, so today diet has derived from the ingestion of natural food to an increasingly intake of artificial and less healthy food.
