SAN DIMAS, Calif., Jan. 11 LifeSpan Nutrition offers thenewly released "Uncensored Family Guide To Vitamin D", which reveals the newunfolding science on this essential nutrient that will forever change yourhealth and the health of your loved ones.
Written by health journalist Bill Sardi, the 16-page guide says achievingadequate levels of vitamin D will do more to improve health than loweringcholesterol, taking an aspirin tablet, exercising or taking a multivitamin.
The guide says the public is going to have to disregard outdated advicegiven by their doctors, dieticians, medical textbooks and even The NationalAcademy of Sciences, in order to obtain the amount of vitamin D needed foroptimal health.
Clearly, the textbooks and doctors provide outdated information concerningvitamin D. "There is no way a one-size fits all recommended intake level ofvitamin D can ensure adequacy levels for this essential nutrient when the needappreciably increases during childhood growth, pregnancy and lactation, amongdark-skinned individuals, among those who don't get outdoors during the middayhours, and during winter months, particularly in northern climates," says BillSardi. The guide helps readers determine the right amount of vitamin D fortheir family.
Calling the current recommended "Adequate Intake" (AI) for vitamin D the"Inadequate Intake" level, the guide notes that the AI ranges from 200international units (IU) for children to 600 IU for senior adults(the "Inadequate Intake"), which wouldn't even provide the amount of naturalvitamin D produced from two minutes of total-body midday summer sun exposure.Over the years many health authorities have recommended 20-30 minutes of dailysun exposure to ensure good health.
The guide says 2000 IU "safe upper limit" is absurd -- it represents onlyabout six minutes spent in the sun. There has never been a toxic level ofvitamin D from prolonged sun exposure reported, and total-body summer sunexposure will make about 10,000 IU of natural vitamin D3 in just 20-30minutes, so the 2000 IU upper limit appears to be too low to achieve optimalhealth. Optimal blood levels to prevent bone fractures in senior Americans,provide adequate vitamin D during pregnancy and lactation, far exceed thecurrent upper safe limit.
