Skip past the enriched flour and water on the ingredient list and here's what you get: – animal shortening, corn syrup, high-fructose corn syrup, sugar, modified

corn starch, butter, chocolate liqueur, and so on.

– Any one of these ingredients alone might prompt you to raise an eyebrow, but taken together they should invoke a gag reflex and a sprint for something far healthier.

Food Contains These Three

Learning Objectives for Class:1. Differentiate between carbohydrates, lipids (fats), and

proteins, by what molecules they contain.2. Give examples of the function of each type.3. Use knowledge of function to deduce foods that contain

these macromolecules based on description of a food. (Enriched flour comes from wheat. Wheat is a seed and contains long term stored Carbs for energy and structure, so it contains starch.
