Document Summary
Chapter 2: guidelines for designing a healthy diet. Nutritional claims- standard of food, moderation is daily value: closely regulated by fda, what the vocabulary really means. Good source- a serving contains 10-19% of the daily value for that nutrient (calcium) Excellent source- a serving contains 20% or more of the daily value for that nutrient (vitamin d) Fat-free- contains less than half a gram of fat per serving (so not actually truly fat-free) Low-fat- contains 3 grams or less of fat per serving. Reduced fat- contains at least 25% less fat per serving than the reference. Research: the scientific method, observation, hypothesis- educated guess based on observations, experiment. Epidemiological- making associations between things: example: fat and colon cancer shows a relationship but does(cid:374)"t prove cause a(cid:374)d effect. Case-control- looking at someone with a nutritional deficiency compared to someone without one. Chapter 3: the human body: a nutritional perspective.
