Nutrition

Nutrition provides the cells of an organism with food, in a form they can use. Organisms need food to be able to keep their bodies working properly. They also need food to be able to do certain things. Malnutrition can happen when a person does not eat the right amount of nutrients. They can get better by changing their diet to have the right amount of the various nutrients. Different organisms have different food requirements, and they eat different things in order to meet those requirements. Animals that do not eat meat, for example, will have to get certain nutrients like protein from other foods. A nutrition expert is called a dietician. Nutritionists are different because they do not need the government to recognize them as experts. Anyone can call themselves a nutritionist. `
