kJ, kilojoules is a unit of energy widely used in nutrition. Kilojoules are the metric measurement of calories. When we eat and drink, we put energy into our bodies. Our bodies use up that energy through everyday movement.
Every cell in our body requires energy to function in its optimal capacity. We need to nourish our bodies right. If we don’t get enough nutrients that calories provide, there will be negative consequences.
