Fortification means adding vitamins and minerals to foods. The government regulates the addition of certain nutrients to foods to ensure Canadians do not fall short. Some examples include:
• Adding vitamin D to milk
• Adding iron to cereal
• Adding folic acid to flour
• Adding iodine to salt
• Adding Vitamin C to apple juice
• When we eat some organic foods we miss some of these things. Read your labels.
