Many fad diets claim we should eliminate dietary carbohydrate in order to lose weight. The truth is that calories from all sources need to be managed for weight control For this discussion, read the following article: Rodriquez, D. (2013 Mar 27) Good vs.Bad Carbohydrates. Retrieved from http://www.everydayhealth.com/diet-nutrition/101/nutrition-basics/good-carbs-bad-carbs.aspx Next create a post that answers the following questions in your own words based on what you learned. 1) How does the information in the article compare to what you have heard about different types of carbohydrates? 2) Identify two specific choices (food or beverage) you might make in order to replace a âbad carb' with a âgood carb' in your own diet. (Choose examples beyond those listed in the article and from two different food groups) 3) The average American tends to consume excessive simple and added sugars (âbadâ carbs), while lacking in âgood carbsâ from dairy, whole grains, fruit and starchy vegetables. Do you agree? Have you observed this? Think about a time when you have observed others eating at a restaurant, cafeteria, or even family members at home. Discuss your observation and thoughts about carbohydrate consumption of others.
