In the 1950s, a surgeon in Topeka, Kansas named Samuel Zelman was operating on a patient at whom he knew personally because the man was an aide in the hospital where he worked. He known for fact, the man did not drink any alcohol. So he was surprised to find out what that his liver was packed with fat just like one of my patients decades later. More than one in four people on this planet have some degree of NASH or it's precursor known as non-alcoholic fatty liver disease. They thought initially that kids were just binge drinking and that they had this fatty liver but it was just because our freaking diet was heinous.
