The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius.

Micronutrients are essential dietary elements required by organisms in varying quantities to regulate physiological functions of cells and organs. [1] [2] Micronutrients support the health of organisms throughout life. [3] [4] [5] In varying amounts supplied through the diet, micronutrients include such compounds as vitamins and dietary minerals.
