DB 222 個未讀回復。22 個回復。Now for the DB topics related to your reading (Chapters 1,2)– A response is required for both topics I and II;  for your third response, you can choose among topics 1-3. I. The first two chapters explain the fundamental of nutrition. The different nutrients, their functions and the old and ongoing research on the science of nutrition. As we all know, there are many existing myths and conflicting facts about nutrition. It will therefore be helpful to everyone to reflect upon how we get our nutrition information. How do you know that what you read in the newspaper or Internet is scientifically sound and accurate? Can we really detect good nutrition information from misinformation? How? What should we look for? Discuss. Also– Find an article or YouTube on Nutrition Quackery, share it with your classmates, and briefly review.II.  Chapter 2 discusses the tools available for designing healthful diets. The USDA’s ChooseMyPlate (formerly MyPyramid (FGP) is explained and illustrated in this chapter. Harvard also has a pyramid and plate:  “Healthy Eating Plate and Pyramid” is (To see it, click on http://www.hsph.harvard.edu/nutritionsource/pyramid (連結到外部網站。)連結到外部網站。.  (Scroll down past the plate to view the pyramid.)  Which do you prefer? Why? Explain……   Also: Google: ‘Food Pyramids from around the world’, or ‘Food Guidelines from around the World’– and click on a link, or click on images, and then select a food guide from another country. Include a picture of the pyramid/guideline, or include the link, and then discuss and compare to our U.S. guidelines…. (There are all sorts of them out there- from India to Bahamas to Belize to Benin, a variety of European, African and Asian countries, etc). You could also select a country of interest, and then type in the country’s name and food guide pyramid, to see what comes up…..)III. Choose one of the following for your third discussion:  1. What do you think of the serving sizes and portion sizes suggested by the FGP? Are they reasonable? Can you visually estimate the serving and or portion sizes?   2. What do you think of the labels on food products? Are they informative? How often do you read food labels? What do you look for in a food label? Are they user friendly?    3.  Anything else you want to talk about from these first two chapters?Your minimum of three responses (Topics I-III must all be addressed for full credit) are due by midnight on Sunday.I encourage you to respond to each other so as to get discussions going- these are a lot of fun and a great way to learn and share ideas…
