Individual cases don't have the validity of long-term studies. It is incredibly important to look at the data, examine the studies and see what 'works.' Many times, we discover a piece of information that catches our attention and can lead us to look further - and we may discover a plethora of information that can successfully help control or cure disease. One of my favorite examples is that of Dr. Saray Stancic, who was diagnosed with multiple sclerosis. She noticed an article in a medical journal about improvement in some people with MS symptoms who consumed blueberries. This led her to research further about diet and MS. She discovered literature showing that whole food, plant-based eating brings great improvement and even elimination of symptoms of the disease.
