question 6

Multiple Choice

Evaluate the following: Food insecurity, in terms of a healthy diet, is only a problem faced by lower socioeconomic groups-not the middle and upper classes.

• A) Food insecurity takes place at all levels, but in the middle and upper classes it is in terms of how much is spent (e.g. higher-priced natural foods, vegan and raw diets), not in how little food they can get.
• B) This is true, since the middle and upper socioeconomic groups have the income to afford food and insecurity among them would be an anomaly, such as is exhibited by survivalists.
• C) The wealthy also have poor diets-but they have the means to undo the damage (doctor-managed diets, health clubs, Weight Watchers, etc.).
• D) This is true. Diseases such as anorexia are restricted to White, upper-class girls and women, for example.
