The amount of energy they provide is measured in kilo-calories (kcal) 1 calorie is the amount of energy it takes to warm 1 gram of water up by 1 degree celsius. Food energy is measured in kilo-calories (kcal) but its oten called calories. I think of kcals as fuel for a car. You might put 60 kcals of food fuel in your body. You burn the calories so you can live and move. You might put 60 l of gar in your car. The car burns the gas so it can move. Diference is you cannot tell how many calories are enough for you but a car tells you when you have enough gas. Carbs give you 4 kcal of energy per gram. Protein gives you 4 kcal of energy per gram. Fat gives you 9 kcal of energy per gram. Minerals are elements from the periodic table that our body needs to funcion ex iron.
