Certainly any great building must be constructed upon a solid foundation. So let us go ahead and commit ourselves to building a solid scientific foundation to explore nutrition. So, before we begin to learn how to nourish our body, we need to have a better understanding of what needs to be nourished. Our body is the product of nature and as such it must adhere to the basic laws of nature. In fact, you can think of nutrition as the scientific offspring of more basic sciences such as chemistry and biology. Therefore, understanding the what's, why's, and how's of nutrition will be a lot easier once a few basic areas of chemistry and biology are appreciated. What follows are some fundamental principles of chemistry and biology and a description of their relevance to nutrition and the body.
