A body that is improperly fueled, or overweight but undernourished, cannot sustain health over the long term. Macro- and micro-nutrients, like proteins, carbohydrates, vitamins, minerals and enzymes, all affect cellular nutrition; cellular nutrition affects the entire body. Some foods like sugar, alcohol, and refined carbohydrates can actually damage health, especially when taken in excess. Nutritional counseling can help correct all of these problems.
