Dan, I appreciate your point. However, I would underscore the importance of #1 healthy lifestyle, healthy eating which would go a long way towards preventing these conditions in the first place (this is not about blaming or judging, but lousy food and exercise habits have a huge impact on these issues) and the other point is that we have to know our own bodies. This was a general article, and if we have the slightest bit of common sense, we do our own research, question our doctors, and learn our bodies. After all, we inhabit them, and they are our responsibility. As for how much is too much? As with all things, it depends on everyone’s individual physiology. We have to know ourselves, know our bodies, and make decisions based on what we see, know and experience. A doctor cannot do that for us. I would be more focused, if I were ill, on how more movement and overall healthier eating could make significant improvements in my conditions. Because study after study does show that those two things do more for us than just about anything else. Salt intake? I’d worry more about whether or not I get out and walk. Am I eating my fruits and veggies. I’d take vacuum to the tons of crackers and Cheetos and Oreos and all that other handy junk that lives in the middle aisles of the store and focus my attention on the beauty of just good fresh food. But that’s just me. Our hearts fail for good reason. Largely because we didn’t respect them enough to take good care of them. Remarkably, the body loves to be healthy, and when we gently, carefully begin to do just that, so-called medical miracles happen. They’re not. It’s just the body doing what it is infinitely well-designed to do. Thanks for your comments.
