So are you talking about cancer or living longer/healthier?
Look, no one will argue with you that eating well will make you healthier and less prone to disease (possibly even some forms of cancer) but you're jumping all over the place and making claims that have no scientific evidence to support. In fact, most of the things you post about here I don't completely disagree with. You just have a tendency to go way overboard with it.
What i'm saying is all based on the premise of my opinion that it's all tied together. Building a healthy foundation in itself will prevent cancer from materializing. It's all about the alkaline versus acidic bodily state.
