Food labels often contain the word “fortified”. This means that one or more ingredients have been added that are not normally found in that food item. The purpose is to increase the amount of that mineral or nutrient to serve a dietary purpose. Table salt is fortified with iodine (to help prevent hypothyroidism, which can lead to goiter which is the abnormal enlargement of the thyroid gland), and many breakfast cereals are fortified with fibre (to improve digestion) and iron.

The purpose of this demonstration/activity is to illustrate the importance of proper labeling and identification of substances and the presence and form of iron in breakfast cereals.
