So there are some possibilities for an investigation on the amount of Vitamin C in various fruits, vegetables, and juices. Without Vitamin D, calcium is just not absorbed. When young children are deprived of Vitamin D they develop a disease called rickets. It is very easy to understand this because you already know that calcium is needed for growth of teeth and bones. If you have rickets, your bones do not grow properly.
Adults deprived of Vitamin D develop a similar disease called osteomalacia.
What is more interesting about Vitamin D is that it can be made in our skin providing that we get enough sunlight. However, this depends upon how much sunlight we get and how much pigmentation there is in our skin.

Similarly there are essential amino-acids which must be present in the protein which you eat. Copyright 1997 - 2000 Gondar Design.
