Acupuncture for hypertension – more evidence that it does not work

acupuncture for hypertension

The claims for acupuncture have any clinical usefulness are vastly overblown with evidence ranging from weak to nonexistent to dangerous. As Steven Novella at Science-Based Medicine once wrote, acupuncture is nothing more than “theatrical placebo.” On the long list of ridiculous claims for this pseudoscience is using acupuncture for hypertension treatment – and once again, real biomedical science shows it is worthless.

And now, it’s time to examine a systematic review that debunks the false claim that acupuncture for hypertension is useful.  Continue reading “Acupuncture for hypertension – more evidence that it does not work”

Vitamin D and high blood pressure–probably ineffective

supplementsVitamin D is a group of fat-soluble steroid-like biochemicals that have one known responsibility in human health–enhancing intestinal absorption of calcium and phosphate, minerals which are necessary for bone development and bone health. In humans, the most important D vitamins are vitamin D3 and vitamin D2, both of which can be ingested from dietary sources, including fishes, milk products, and many other foods. However, the body can synthesize vitamin D’s in the skin when exposure to sunlight is adequate. Because humans can produce their own vitamin D, it is not strictly considered an essential dietary vitamin, which are vitamins that cannot be synthesized in sufficient quantities by an organism, and must be obtained from its diet.

Even though supplementation is necessary for people who aren’t receiving adequate levels of vitamin D through either sun exposure or diet, excessive intake of the vitamin causes a condition called hypervitaminosis D. Excessive vitamin D can lead to acute problems, like excess thirst or increased urination, but over a long-term can lead to heart disease and other chronic conditions.  

Despite the understanding that vitamin D has only one real function, regulation of calcium and phosphate uptake, that hasn’t stopped the junk medicine pushers from making all sorts of claims about its usefulness in human health. In fact, recent studies have shown that vitamin D doesn’t reduce the risk of breast cancer, one of the more popular myths about the vitamin.
