Personally, I see the acid vs alkaline factor more as a piece of a complicated puzzle than a complete picture. You are so right that some experts become so fixated on a certain cleanse, diet or supplement that they loose sight of the whole body. This is more of an allopathic approach to health where individual symptoms are treated instead of taking a holistic approach. I believe proper diet, pure water, supplements and cleanses when indicated all help bring the body into balance and that is what leads to overall good health. Sometimes we do need to focus on a particular problem and make it our priority, but the welfare of the whole body should never be neglected or overlooked. Some organs need to be on the acidic side, a balanced body will allow this, an artificially alkalized body may not be as healthy as some claim it would be.
