It appears that Vitamin D, like the Tea Party and all white people, is racist. It refuses to help blacks counter heart attacks:
Low levels of vitamin D, the essential nutrient obtained from milk, fortified cereals and exposure to sunlight, doubles the risk of stroke in whites, but not in blacks, according to a new report by researchers at Johns Hopkins.
Stroke is the nation's third leading cause of death, killing more than 140,000 Americans annually and temporarily or permanently disabling over half a million when there is a loss of blood flow to the brain.
Researchers say their findings, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Chicago, back up evidence from earlier work at Johns Hopkins linking vitamin D deficiency to higher rates of death, heart disease and peripheral artery disease in adults.
The Hopkins team says its results fail to explain why African Americans, who are more likely to be vitamin D deficient due to their darker skin pigmentation's ability to block the sun's rays, also suffer from higher rates of stroke. Of the 176 study participants known to have died from stroke within a 14-year period, 116 were white and 60 were black. Still, African Americans had a 65 percent greater likelihood of suffering such a severe bleeding in or interruption of blood flow to the brain than whites, when age, other risk factors for stroke, and vitamin D deficiency were factored into their analysis.
No word on Vitamin D's attitude toward women, homosexuals, Muslims, or Hispanics.
