Nutrition - great or poor - has a direct correlation to whether or not we as human beings will develop health issues, certain disease, cancer and possibly death. Without a good balance of the nutrients we require, we can't expect our body's chemical and mechanical response to be that of positive nature. And to curb the onset of disease such as diabetes, heart disease, etc. it is imperative that we all understand the impact our food choices will make. While genetics for certain diseases may not be in our favor, we can still improve our chances of deflecting them by making the right choices in what we consume. In a 2011 case study on prostate cancer by Hardin, Cheng, and Witte, they solidified the theory that a diet rich in vegetables and low in high glycemic foods "decrease [the] risk of aggressive prostate cancer." (Hardin, Cheng & Witte, 2011) Additionally, of all causes of death in the United States, four of them - most importantly the top three - are all a result of nutrition and they are heart disease, cancers, strokes and diabetes. (Sizer & Whitney, 2011)
"The nutrients in food support growth, maintenance, and repair of the body. Deficiencies, excesses, and imbalances of energy and nutrients bring on the diseases of malnutrition." (Sizer & Whitney, 2011, p. 2)
