Fat-soluble vitamins have more kilojoules than water-soluble vitamins

False. Neither the fat-soluble vitamins A, D, E and K nor the water-soluble vitamins B and C add significant kilojoules (energy) to our diet. All vitamins are essential nutrients and although not every vitamin is needed daily in our diets, it is sensible to eat a variety of foods to ensure that, over the longer term, the full range of essential nutrients is provided.
