Prevent and Reverse Heart Disease by Caldwell Esselstyn is WOW! My wife and I have been following a vegan diet for quite a few months now but used olive oil liberally. After reading this book, we have cut back on its use. This diet has helped us to reduce weight, and when the labs returned, all our parameters are well within the reasonable limits. This book just validated our approach to a healthy diet. I’d say this book should be a must read for every individual.
