Answer to Question 1

The extent to which a nutrient or other food component is absorbed is called its bioavailability. The bioavailability of a particular nutrient can be influenced by physiological conditions, other dietary components, and certain medications. Nearly all the products of carbohydrate, protein, and lipid digestion are 100 bioavailable; however, the absorption of other nutrients (such as calcium and iron) is dictated by the physiological needs of the body. Usually, the body absorbs only the amount of iron and several other nutrients that it needs, and excretes the excess in feces. This regulatory step helps protect us from toxicities that could result from having too much of some nutrients.
