Correct! A unit of energy. A calorie is a unit of energy, heat energy to be exact. Calories are found in certain food components: protein, fat (or lipid) and some carbohydrates. Vitamins, minerals and water do not contain calories. Alcohol also contains calories. Which of the following foods is naturally a good source of calcium? A. Orange juice B. Milk C. Spinach D. All of the above E. B and C only Correct answer: E. Both milk and spinach are natural sources of calcium. Calcium is an essential nutrient in the diet. At roughly 300 mg of calcium per cup, milk is an excellent source of this nutrient. Non-dairy foods don't pack the calcium punch, but spinach (146 mg calcium cup per cooked spinach) isn't so bad. Food companies promote orange juice as a source of calcium and vitamin D, but both are added to orange juice before it is pasteurized in a process known as fortification
