Diet and nutrition is a category which encompasses how and what a person eats, and the associated nutrition derived from this intake. It is a factor of a person’s health, as one must have a proper diet, and also proper nutrition, to give their body what it needs.

Diet includes not only what a person eats, but how much they eat, and when they eat. Some people think of a diet as restricted eating with the goal to lose weight, however, a diet is simply your intake of food in general. http://www.healia.com/healthguide/guides/diet-and-nutrition/what-is-a-diet http://www.theindychannel.com/health/3555485/detail.html Special diets can be used for weight gain, weight loss, to decrease sodium, or to achieve other goals. http://www.theindychannel.com/health/3555485/detail.html Many countries also have more specific diets, such as the people in Japan whose diets are comprised mainly of rice and seafood, where as other regions have drastically different diets. http://wordnetweb.princeton.edu/perl/webwn?s=diet

Nutrition comes from what is in the food and drinks a person consumes. http://wordnetweb.princeton.edu/perl/webwn?s=nutrition This includes calories, sodium, protein, vitamins and minerals. A person must have a balanced diet in order to obtain the proper nutrition their body needs. A lack of nutrition (such as a limited calorie intake) or poor nutrition (such as a restrictive diet) can lead to serious problems and poor health. Each of these things serves its own purpose in the human body, to provide energy, aid in repair, and help the body grow. http://www.medicalnewstoday.com/articles/160774.php http://www.eguruguide.com/ Nutrition as a whole is the scientific study of food in humans. http://wordnetweb.princeton.edu/perl/webwn?s=nutrition
