We all know that one of the key nutrients provided by an orange is vitamin C. The health benefits of vitamin C have been promoted for decades. Vitamin C is so important that hundreds of companies now manufacture vitamin C to their food products. That seems like a good thing. In fact it is a huge mistake.
An orange contains so much more than vitamin C. It contains hundreds of nutrients, minerals, and phyto-chemicals. These co-factors work synergistically with each other. Without them vitamin C is not nearly as effective. Vitamin C needs all of these other beneficial compounds in order to work as effectively as possible. When you isolate vitamin C from all of the other nutrients in an orange you severely limit its potency.
This is the basis for whole food nutrition. Food consumed in a state as near to nature as possible is far healthier than food that has been processed, isolated and fractionated into its individual nutrients.
