HUMAN NUTRITION

Detailed explanation-1: -Fast foods are typically high in fats, thus they have more calories as a result. They also tend to be high in sugar and salt, but sugar doesn’t typically add more calories than other carbohydrates or proteins and salt doesn’t add any calories at all. So the main cause for high calories in fast food is fat content.

Detailed explanation-2: -Thus a single fast-food entree has nearly half of an entire day’s allowance of salt. Sides increased from 14% of the RDA to 26%, which means that if you have an entree and a side (fries!), you’re getting 75% of your daily salt allowance.
