If you are worried about your cardiovascular health, one of the things you want to avoid is salt. This was based on ancient research that seems to show even moderate salt intake could do all kinds of bad things for your cardiovascular system.
I was always skeptical of these claims because if you’ve got a healthy set of kidneys, the body has an amazing ability to regulate salt levels in the body. Of course, maybe there is some level of salt consumption that increases the blood pressure, cause retention of water, and other issues that lead to cardiovascular issues.
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.
Vitamin 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.
