Discretionary calories: extra calories leftover from food budget Examples: candy, cupcakes, cookies, chips, snacks 5. What are the key things you should look for on the food label when choosing a healthy food? The top ingredients (most abundant by weight) % DV of listed nutrients (5% = low, 20% = high) Size of serving and calories per serving (nutrient density) Sugar, partially hydrogenated oil (0 g trans fat means <.5 g trans fat so sometimes they make the serving size smaller so that trans fat is absent. Always look at sugar for partially hydrogenated oils, which indicates that there is sugar). Sodium should be less than 2300 mg (<2300 mg) 6. What are the differences between structure/function, health and nutrient claims? What are the requirements for nutrient claims? Structure/ function claim: names nutrient and its function in the body. For example, “calcium builds strong bones.” - Structure/ function claims are not regulated by the FDA. It is the manufacturers responsibility to ensure the quality and safety of the food product. Health claim: Names a nutrient and states how it can prevent a disease - The FDA does approve of these health claims and the health claim is backed up by a general scientific consensus and research. The health claim must say that it “may” or “might” reduce the risk of a chronic disease, because people’s genes can prevent a food product from working properly. No Health Claim can say that it will prevent the risk of a chronic disease.
