I used SmartFOOD to prepare for a marathon to ensure a varied and balanced daily diet. It is especially important to me that SmartFOOD foods are free of preservatives and any flavor enhancers. There is no white sugar or salt. This is generally quite rare in today’s food market in my opinion. I believe that although I made above-average choices in my diet before, the new experience with SmartFOOD took my daily diet to a new level.
