Nutrients are substances found in food that are needed for good health.
Your body can't make nutrients, so they must be supplied by food. During digestion, food is broken down into nutrients, which are absorbed into your bloodstream and carried to every cell in your body. Each nutrient has a specific function and they all work together for your good health. Carbohydrates- are the body's main source of energy or calories. Fiber, which is another carbohydrate, aids digestion and helps fight some diseases but is not a nutrient because it is not digested and absorbed by the body.
