Energy density is defined as calories per gram of food. Which of the following foods is high energy density?

Explanation:
Energy density is calories per gram of food. Fats and oils provide about 9 kcal per gram, which is more than double the calories per gram of carbohydrates or protein (about 4 kcal/g) and far more than water (0 kcal/g). This means foods rich in fat deliver a lot of calories in a small amount of weight, making them high in energy density. In contrast, water-rich foods like fruits and vegetables, especially non-starchy ones, add weight without many calories, resulting in low energy density. So fats and oils stand out as high energy density.
