Worst Food in America Can you decide?

Worst Individual Snack 520 calories 45 g sugars 24 g fat (14 g saturated, 1.5 g trans) 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. –Saturated Fat Equivalent: 2 McDonald's Quarter Pounders

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.

Learning Objective 1: Organization Chart Your group will be organizing these items from the macromolecules assessment into Carbs, Lipids & Proteins monosaccharide disaccharides glucosefructose sucroselactose polysaccharide glycogen starch cellulose fatty acid glycerol phospholipidphosphate steroidcholesterol testosterone triglyceride amino acid Simple sugar
