Ever noticed that restaurants don't post nutritional information? Some do, but by and large, they don't. Well, a recent American Journal of Public Health study shows how far off we can be in estimating the calorie and fat content of common restaurant choices. And, sadly, the less "healthy" the choice, the greater we underestimate calorie and fat content.
Approximately 200 individuals (80% college graduates) who ate out at restaurants (14 meals eaten out in past month) were asked about the nutritional content of common food items encountered in restaurants (keep in mind average daily nutritional intake should for most of us be at 2000 calories and no more than 65 grams of fat - lower is better).
Consumer estimate Actual
Hamburger and fries 777 calories, 37 grams fat 1240 calories, 67grams fat
Chef salad 452 calories, 21 grams fat 930 calories, 71 grams fat
Fettuccine alfredo 704 calories, 31 grams fat 1500 calories, 91 grams fat
Cheese fries with ranch 869 calories, 40 grams fat 3,010 calories, 217 grams fat
I included the last option from the study due to football season! In general, consumers estimates were HALF the calorie and fat content. No wonder why restaurants aren't keen on labeling food content or portions the way the FDA requires food in our grocery stores.
Ironically, consumers estimated more-healthful items (turkey sandwich, chicken) much more accurately - so its not as if they don't at some level, "know" the difference.
Bottom line - enjoy "eating out" but generally speaking, doing so less often, asking about nutritional info if not posted, and becoming more informed will prevent adding the usual 1-2 pounds per year!
