Last year, when she was just 23 years old, Carmen Johns was diagnosed with multiple sclerosis. MS is a degenerative disease that slowly, and permanently, damages the central nervous system. There is no known cure. There are drugs to treat the symptoms, but the side effects can be harsh. So Carmen’s mom, journalist Maria Bustillos, decided to investigate. She looked into a lot of academic studies and discovered one that seemed deceptively uncomplicated….and effective: a simple vegan-plus-fish diet could dramatically relieve MS symptoms. The study took place in the 1950s but few doctors today either recommend this diet or even know about the study behind it.
