Nutrition, according to Wikipedia is the process of providing or obtaining the food necessary for health and growth. Diet is the kinds of food that a person, animal, or community habitually eats.
The modern concept of diet often implies the use of a specific intake of nutrition for health or weight-management reasons. In our days everybody is on some kind of diet dictated by the latest publication or book. The question goes: does an universal diet exist?
Diet is not about if one or another food is good or bad for you because a diet book says so, but in identifying what impact that recommended “healthy” food has on an individual’s body.
Research shows that consumption of the same foods can have different impact on different people. The conclusion is that there no universal rules of dieting. The key is finding out what is good for YOU with respect of food choices. This can be obtained through identifying food sensitivities and nutritional deficiencies.
