Although calcium compounds have been used since ancient times, and metallic compound was isolated by Sir Humphrey Davy way back in 1808, it was only very recently that calcium was used as a dietary supplement to compensate for dietary losses. The Hippocratic adage that all food is medicine is followed with reluctance only. Various myths and misconceptions hinder proper dietary intake that, in turn, exacerbate the diseased condition. One such myth is the ridiculously low RDA, or Recommended Death Allowance, for many minerals and vitamins, including Calcium. In a series of highly documented treatment, Dr. Carl Reich found that extremely high dosage (much above the RDA) of Calcium and Vitamin D were surprisingly successful in treating allergies, Attention Deficit Disorder and even cancer or diabetes. In a famous experiment, some experimenters cut a cancer tumor in half, and put it in two containers of body fluids at 98 degrees F, one of which contained a pinch of calcium salts. After four days the normal beaker had a four times larger tumor, and the calcium beaker had a four times smaller beaker. Miracle? Yes, but it is perfectly rational. The calcium is an alkaline metal, and makes a compound called calcium monoorthophosphate in the blood, something that raises the Ph balance of the blood. Blood with a higher Ph can absorb more oxygen, at times upto twenty times more. Insufficient oxygen results in the blood squeezing calcium out of bones, saliva and body fluids, something that results in calcium deficit disorders, like weak bones and osteoporosis. The bones contain 99% of the calcium in the body, and it is this supply that slowly gets depleted, resulting in some calcium deposits around bone joints (which fool some doctors ignorant of nutrition to advise stopping of calcium ingestion). It was found that many of the traditional cultures took a diet that in popular perception should be very unhealthy, but those cultures did not have any medical history of disease. For example, the Eskimos and the Inuits of northern North America, until very recently, took an exclusively meat diet of which about 80% was blubber fat. Yet, the Eskimos did not have any heart diseases, cancer or diabetes. Most of the indigenous populations in the mountainous regions of South America, Central Asia and Afghanistan, and many places in China and India have a primarily animal diet. Their main water source is glacier water that is saturated with undissolved calcium. In most places their daily calcium intake was dozens of times above the RDA, and yet these people are perfectly healthy. In Okinawa, Japan, the diet includes loads of coral calcium that has a great absorption rate. There too people were completely free of many of the lifestyle diseases that afflict Caucasians. All this goes on to prove that plentiful supplies of minerals and vitamins are always helpful. In fact, Dr. Robert Barefoot, partner of Dr. Reich, mentions that everything god created it good and one may take it without compunction. Such plentiful supplies of natural calcium are not available everywhere, nor individual dietary habits permit such natural calcium intake. In such cases one may take alternative natural dietary supplements like milk, cheese or butter. And if one is averse to such supplements as well, there are many calcium mineral supplements available. Remember, so far is calcium is concerned, there is never too much of it.
