Document Summary
Nutrients: substances in food that provide structural materials or energy. Macronutrients nutrients that are required in large amounts such as water, proteins, fats, carbs. Can be stored for later use by the body. Body digests complex carbs more slowly than it does simpler sugars because they have more chemical bonds. Roughage is a dietary fiber composed many of complex carbs that cannot be digested by humans. Bio quiz 3 notes: essential fatty acids: fatty acids that cannot be synthesize by the body and must be obtained through diet such as omega 3 and omega 6 through fish consumption. Saturated fat: when the carbons of a fatty acid are bound to as many hydrogen as possible (fats found from animals typically such as butter: pack more tightly together to make a solid structure. Unsaturated fat: when there are carbon-to-carbon double bonds, the fat is not saturated in hydrogen (fats found from plants typically such as cooking oils)
