Today we're going to dive into a touchy subject: Body odor. We are not going to dance around the subject, either, because body odor can actually be an important indicator of your overall health and dietary habits. What you exhale through your breath and your skin is a good indicator of what's going on inside your body. If you start to stink within hours of not using deodorant, rest assured there is putrefaction or fermentation going on inside your body, and that indicates a poor diet, usually.
