People are not aware that whenever they eat out, whether at a fast-food outlet or a full-service restaurant, they end up consuming about 200 additional calories than eaten at home, says new study. Besides, you also take in more saturated fat, cholesterol and sodium than those who prepare and eat their meals at home.
"People who ate at full-service restaurants consumed significantly more cholesterol per day than people who ate at home," said Professor Ruopeng An, University of Illinois.

While people who eat at restaurants tend to take in more healthy nutrients - including certain vitamins, potassium and omega-3 fatty acids than those who eat at home or at a fast-food outlet. The restaurant diners also consume substantially more sodium and cholesterol - two nutrients that Americans generally eat in excess, even at home.
Fast-food and restaurant diners consumed about 10 grams more total fat, and 3.49 grams more saturated fat than those who dined at home.
"The American Heart Association recommends limiting the amount of saturated fats one eats to less than 5 to 6 percent of one's total daily calories. That means that if one needs about 2,000 calories a day, less than 120 calories, or 13 grams, should come from saturated fats," An said.
"Eating at a fast-food outlet adds about 300 milligrams of sodium to one's daily intake, and restaurant dining boosts sodium intake by 412 milligrams per day, on average," An added.
Recommendations for sodium intake vary between 1,500 and 2,300 milligrams per day, but Americans already consume more than 3,100 milligrams of sodium at home, An found.
"The additional sodium is even more worrisome because the average daily sodium intake among Americans is already so far above the recommended upper limit, posing a significant public health concern, such as hypertension and heart disease," he said.
