Even if you eat your 5 a day, that is no guarantee that you are getting all your body needs.
The problem begins with soil.
The soil dictates the mineral and vitamin content of the food we eat, and the animals we eat that have grazed.

Unless you grow your own fruits and vegetables and eat them raw the same day you pick them, you're not getting what nature intended.
Although they look great and taste fresh you just don't know what's in there.

Soil Depletion -- Continuous cropping; fertilization with only nitrogen, phosphorous and potassium; soil erosion; and other factors have decreased the minerals in topsoil. We are now growing large amounts of food that in many cases are lacking some of the basic minerals needed to sustain life. Lacking vitamins, the body can make some use of minerals, but lacking minerals, vitamins are useless!

Transport & Storage -- Dr. Michael Colgan tested oranges that had been picked the same day, and their vitamin C content was 180 mg. He then tested oranges from the same grower which had been in storage at a local supermarket. They looked and tasted the same, but the vitamin C content had dropped to zero. How much vitamin C is in your orange?
