Intro
The seeming simplicity of our daily activities is greatly contrasted by the complexity of our true nature—quite a paradox, no doubt. It is simple in that, on the outside, the goals of our body may appear few. We internalize food, water, and oxygen while at the same time ridding ourselves of carbon dioxide and other waste materials. These operations support reproduction, growth, maintenance, and defense. Yet on the inside our body may seem very complex as various organs participate in a tremendous number of complicated processes intended to meet the simple goals previously mentioned. Nutrition is just one part of this paradoxical relationship. The objective of nutrition is simple: to supply our body with all of the necessary nutrients, and in appropriate quantities, to promote optimal health and function. However, in practice, nutrition is far from that simple. There seem to be too many nutrients, controversial nutrients, and different conditions, such as growth, pregnancy, and exercise, to allow nutrition to be a simple topic. Although we have long appreciated food, it has only been in the more recent years that we have really begun to understand the finer relationship between food and our body. Most nutrients have been identified within the last century or so and right now nutrition is one of the most prevalent areas of scientific research. This is to say that our understanding of nutrition is by no means complete. It continues to evolve in conjunction with the most current nutrition research. It seems that not a week goes by without hearing about yet another discovery in nutrition. It is hard to believe that just a few decades ago the basic four food groups were pretty much all the nutrition known by most people. Today nutrition deeply penetrates into many aspects of our lives, including preventative and treatment medicine, philosophy, exercise training, and weight management. Our diet has been linked to cardiovascular health, cancer, bowel function, moods, and brain activity, along with many other health domains. We no longer eat merely to satisfy hunger. Without doubt, nutrition has become a matter of great curiosity and/or concern for most of us today.
