People talk a lot about the word “nutrition.” So, what is nutrition? Nutrition is the study of how food and drink affect our bodies, our health,and our wellness. Food can either be a good natural medicine for your body, or a slow poison that leads to the development of chronic diseases such as diabetes, autoimmune disease, MS, Alzheimer’s, and even cancer. There’s really no in between. It’s either good for you or bad for you.
