Vitamins and Minerals: Sources and What They Do

vitaminsminerals

 

Water soluble vitamins and fat soluble vitamins are nutrients your body needs in your diet for you to stay healthy.  For optimal health, it is important to get the vitamins and minerals your body needs—either through a healthy diet, health supplements, or both. Your body requires two kinds of vitamins: fat soluble vitamins (A, D, E and K) and water soluble vitamins (B-complex and C).

Water soluble vitamins, which are highly soluble, require daily replenishment in your body. Fat soluble vitamins, which are also essential for your health and stored in your liver, do not need to be replaced every day.

There is a misconception out there that people should avoid fat all together, this is false.  We NEED fat in our diet for a variety reasons, as our digestion needs it to work properly.  Also, certain vitamins (A, D, E, and K) require fat for our system.  Without fat, these vitamins would be useless.  The key is to choose the healthier fats, such as butter or light butter, safflower, sunflower, or coconut oils, and extra virgin olive oil.
