Calories provide energy for everyday life
- Body organs eg, brain, heart, liver, ovaries, testes, thyroid, and kidneys, and tissues eg, nerves, bone, muscle, skin, gut, and immune system need energy provided by the molecule adenosine triphosphate (ATP) for normal healthy everyday function.
- Malnutrition due to a chronically inadequate calorie intake and supply of energy is characterized by a deterioration in all organ and tissue functions and associated ill-health and disease.
