Answer:
Foods that are nutrient-dense give your body more than just calories; nutrient-dense foods provide the body with essential vitamins and minerals, whereas foods that aren’t nutrient-dense give the body only calories.
The body accesses nutrients through digestion, which begins in the mouth. Saliva and chewing break down the food. The esophagus empties into the stomach where protein is digested. Fat, carbohydrates, and leftover proteins are digested in the small intestine. The colon helps to absorb fluid. The pancreas, gallbladder, kidneys, and liver are also involved in digestion.

d. Pizza—It probably contains less fat; the sauce has a small amount of vitamins.
e. Oatmeal—It contains more fiber, probably less fat, and more vitamins and
minerals with fruit.
