VITAMIN D AS HEALTH MARKER. "Decreases in vitamin D levels are a marker of deteriorating health. Ageing and inflammatory processes involved in disease occurrence and clinical course reduce vitamin D concentrations, which would explain why vitamin D deficiency is reported in a wide range of disorders." https://lnkd.in/dDKztC5 View in LinkedIn

OLD ROOTS. "In the 1930s, a milk fortification program was implemented in the United States to combat rickets, then a major public health problem. Other dairy products made from milk, such as cheese and ice cream, are generally not fortified. Ready-to-eat breakfast cereals often contain added vitamin D, as do some brands of orange juice, yogurt, margarine and other food products." https://lnkd.in/eVmSxuR View in LinkedIn

D FORTIFIED FOODS. "Fortified foods provide most of the vitamin D in the American diet. For example, almost all of the U.S. milk supply is voluntarily fortified with 100 IU/cup. In Canada, milk is fortified by law with 35–40 IU/100 mL, as is margarine at ≥530 IU/100 g." Like all these public health medication programs, one shoe does not fit all. https://lnkd.in/eVmSxuR View in LinkedIn

MUSHROOM VITAMIN D. "The Australian research investigated the vitamin D levels of three standard button mushrooms exposed to direct midday sunlight. Results confirmed that mushrooms generate vitamin D levels in a similar way to humans and an average serve* can provide 100 per cent of an adult’s vitamin D requirement (10 mcg)." https://lnkd.in/eMmdAs5 View in LinkedIn

D3 BETTER THAN D2. "Drisdol is a synthetic form of vitamin D2—made by irradiating fungus and plant matter—and is the form of vitamin D typically prescribed by doctors. This is not the type produced by your body in response to sun or safe tanning bed exposure, which is vitamin D3." https://lnkd.in/ep_VBW6 View in LinkedIn

SUPPLEMENTATION BOOM. "At some point in the last decade, screening blood for vitamin D levels became a routine part of medical care. Feeling a little low this winter? Get a vitamin D test. Think you didn't get enough sun last summer? Check your vitamin D levels. In less than ten years, the amount insurers spent on testing rose from $1 million (in 2000) to $129 million (by 2008). Seventy-five percent of Americans are now on vitamin D supplements." https://lnkd.in/e_BB-rH View in LinkedIn

SUNLIGHT IS GENERALLY SUFFICIENT. "Although the amount of vitamin D adults get from their diet is often less than what's recommended, exposure to sunlight can make up for the difference." Except if obese, taking drugs that interfere, or with other medical conditions. http://www.mayoclinic.org/healthy-living/nutrition-and-healthy-eating/expert-answers/vitamin-d-deficiency/faq-20058397 View in LinkedIn

HOW DID THIS HAPPEN? The new 'crisis' in hypovitaminosis D is sudden and curious. How has it been overlooked by the medical and research community for so long, or is it a new food supplement fad? On searching for an answer, it has not been forthcoming. It is not a lifestyle disease of the spoiled West, but occurring worldwide. The answer remains illusive. View in LinkedIn

WORLDWIDE DEFICIENCY. "Worldwide, an estimated 1 billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups. Indeed, in industrialized countries, doctors are even seeing the resurgence of rickets, the bone-weakening disease that had been largely eradicated through vitamin D fortification." https://lnkd.in/ednKz9W View in LinkedIn

CAUSES OF THE VITAMIN D EPIDEMIC? An engineer's interesting viewpoint. "20 of the 35 reasons for Vitamin D deficiency are new." These include sun avoiding behaviors from various causes. Less cholesterol in food, obesity, increased soft drink consumption (fructose), drugs that interfere with vitamin D. And more. https://lnkd.in/eHHnpna View in LinkedIn
