Answers

  1. D. The Center for Disease Control reports that 34% of adults over the age of 20 are obese; another 34% of adults are overweight. About 20% of American adults are in the normal weight range.
  2. • CDC/National Center for Health Statistics, June 18, 201-, Accessed at http://www,cdc.gov/nchs/faststats/overwt.htm on 3/23/11
  3. B. Only 22% of Americans consume 3 or more vegetables per day consistently. Vegetable intake is lower in young adults. Overweight individuals tend to choose fruit and fruit juices instead of vegetables. Retired Americans and women eat more vegetables than younger adults and men. Source ERS, USDA 2008
  4. A. One serving per day, on average. In fact, in 2000, 36% of Americans averaged less than one serving of whole grains per day in one USDA study. • Cleveland LE, Moshfegh AJ, Albertson AM, Goldman JD, Dietary Intake of Whole Grains, J Am College of Nutrition 19 (90003): 331S-338S.
  5. D 142 lb. of sugar per person per year in 2005 per USDA data. This is 14 Tbsp sugar per day. Sugar intake is up 29% from 1970. 48% of our sugar intake in the United States is from soda, fruit drinks and sweet tea. 19% is consumed as grain and dairy desserts. Only 3.5% of the sugar intake comes from sugar and honey added at the table.
  6. Myth. Both breads contain about 2 Tbsp flour per slice and about 14 gm carbohydrate. Whole grain breads contain 2-4 gm fiber per slice but the difference in carbohydrate content is insignificant.
  7. Myth. Both table sugar and high fructose corn sweeteners (HFCS) are about 42% fructose by weight. In large amounts, both have been linked to dental caries, lower nutrient-density diets, and increased triglyceride levels, which can increase heart attack risk. There is no evidence today to suggest that HCFS create a higher risk for health problems than other refined sweeteners.
  8. C. 34% of Calories is derived from fat and this is unchanged over the past 30 years, at least as a percentage of Calories. However with 500 extra Calories per day consumed today (above typical intake 30 years ago), the total fat intake is up 25 lb. per year.
  9. Myth. Sea salt is up to 2-4% other minerals (in place of sodium) by weight, depending on the sea water that is used. The practical fact is that both are high salt foods.
