The key to obtaining all the nutrients that your body requires is eating the right mix of foods: a balanced diet. This means eating a variety of foods from different food groups that together contain all the vitamins, minerals, and fuel – in the form of the macromolecules carbohydrates, proteins, and fats – your body needs. However, there is not one particular diet that is the best for obtaining all these required nutrients. Vegans, vegetarians, people with diabetes, those with food allergies or celiac disease all have very different diets but can all obtain proper nutrition from what they eat.
