WASHINGTON, D.C. (WPVI) --Americans have a lot of mistaken information on their health, especially on food and nutrition.
A new survey by ORC International says most would flunk a high school health class.
Only one out of 10 questions were answered correctly by a majority of those responding.
Here are some of questions -
What does a calorie measure?
1) The health value of food (19%)
2) The smallest unit of energy humans can derive from food (16%)
3) Whether food is fattening or not (23%)
4) The energy value of food (42%)
Only 42% had the correct answer - the energy value of food.
How many calories are recommended per day for men and women?
1) Men: 1500 to 1800; women 1200 to 1500 (25%)
2) Men: 1800 to 2100; women 1500 to 1800 (47%)
3) Men: 2200 to 2800; Women 1800 to 2200 (24%)
4) Men: 3000 to 3300; women 2700 to 3000 (3%)
Less than 1 in 4 knew that it's 2200 to 2800 calories for men, and 1800 to 2200 calories for women.
The worst response was to this question: Which has more sugar - 8 ounces of orange juice or 8 ounces of Italian dressing?
Only 28 percent knew that it's the Italian dressing.
The best response was to the question: Do 'superfoods' have an official definition from the FDA?
62 percent correctly said 'no.'
