Understand the concept of nutrient density and state how it can be used to determine the healthfulness of foods - Answer-A measure of nutrients provided per calorie of food Foods rich in nutrients relative to their energy content (calories) usually whole foods; lower calroies and higher nutrient foods ex: fruits & veggies = energy dense; spam & candy - not energy dense; whole foods = energy dense Identify the six classes of nutrients. Recall the energy yield (kcal/gram) for carbohydrate, pr...

Protein - Compounds composed of carbon, hydrogen, oxygen, and nitrogen and arranged as strands of amino acids. Some amino acids also contain the element sulfur. Amino Acid - The building blocks of protein. Each has an amine group at one end, an acid group at the other, and a distinctive side chain. Essential Amino Acid - Amino acids that either cannot be synthesized at all by the body or cannot be synthesized in amounts sufficient to meet physiological need. Also called indispensable amino ...
