I don’t recommend it per se, but Dr William Davis’ HeartScan blog makes the testable claim that there is a relatively cheap noninvasive scan which gives a good proxy measure of calcium buildup in the heart, and that using it he has interventions which measurably reduce such buildup, and they overlap with common alternate diets like reduced wheat, carbs, I forget what else. I’m not claiming this is right, but if it is both testable and measurable and not just unsupported claims, it seems it should get more attention. He’s also a cardiologist not an internet tree doctor. I don’t know if he’s a quack. [Edit: https://drdavisinfinitehealth.com/2019/03/why-you-should-get-a-ct-heart-scan/ https://drdavisinfinitehealth.com/2019/03/why-you-should-get... saying "When you get a CT heart scan [...] you’re given a score. What that score is, is the volume of calcium in your heart’s arteries. People go “Why are we measuring calcium?” One, it’s easy to see on a CT scan, so is thereby easy to quantify. [...] Calcium occupies 20% of total atherosclerotic plaque volume. So it’s a gauge, a dipstick, for the amount of plaque you have in your arteries. It doesn’t tell you about blockage [...] A heart catheterization would tell you stuff like: there’s a blockage halfway down, that’s blocking 70 percent of flow. [...] A heart scan tells you something like this: in this 1 foot long piece of iron pipe, there’s 273.85 cubic millimeters of rust — two different perspectives on the same disease. A heart scan gives you a score, a calcium score. Normal is zero. The higher the score, the more plaque you have, and the more likely it is that can lead to heart attack and abnormal symptoms. There’s no specific cutoff. You can’t say “at a score of 500 you likely have a 70% block”. You can’t say things like that. Though, the higher it does go, it does indeed suggest greater potential for a blockage, that blocks flow." "Let’s say you have a score of 500, what now? Well, those of you who have been following along my programs, know that all the things that I do: the Wheat Belly Total Health program, the Undoctored Wild-Naked-Unwashed program — all those programs, the prescriptive part of the programs, came from my efforts to reduce heart scan scores, or at least stop them from increasing. If we do nothing, if you have a heart scan score, say, of 500, and you do nothing, the score goes up 25% per year. What if you take a statin drug, an aspirin, and cut the fat in your diet — cut the saturated fat, and exercise? How fast does your heart scan score go up? 25% per yearThose conventional solutions do nothing to prevent plaque from growing. [...] Those strategies that I put together over the years, and we showed that you could reduce heart scan scores, or at least put a stop to the continual rise. [...] You can actually see on the heart scan images, you see can see the plaque has shrunk (at least the calcium part of it has shrunk)." ] Where else have you seen claims of lifestyle interventions that will stop the growth of calcium buildup/atherosclerotic plaque, or even reduce it, that aren't just backed by argument but by a $150 common proper hospital non-woo test that can show whether it's working or not?
