Nutrients are parts of food that are needed for one of many functions in the body. Nutrients can be broken down into two major categories, macronutrients and micronutrients. Macronutrients are carbohydrates, fats, protein, and water. Micronutrients include all vitamins and minerals as well as a newly discovered class of nutrients called phytonutrients or phytochemicals.
