The current issue of the blue journal<\/a> has more stuff on the vitamin D hypothesis<\/a> (that has been shifted recently<\/a> into the opposite direction). I agree with the editorial that<\/p>\n

\nIntervention studies of vitamin D in the primary prevention and treatment of asthma raise a number of difficult scientific, ethical, and regulatory issues.\n<\/p><\/blockquote>\n

That may be true while the editorial includes the widely quoted myth that immunological effects occur only at high doses (at least it provides no good reference). And sure, I am misquoted with effects on Th2 (never said that) as well as on asthma (so far I talked only about sensitization).<\/p>\n

\nWithout dietary supplementation, humans obtain about 90% of their vitamin D from sunlight exposure and 10% from diet\n<\/p><\/blockquote>\n

is also not correct as a newborn will get 99,5% from sunlight. On the other hand I liked the note that<\/p>\n

\nhumans cannot overdose on vitamin D from sunshine because excessive pre\u00e2\u20ac\u201cvitamin D is destroyed by sunlight to inactive photoproducts, and repeated exposures stimulate tanning. This does not happen with dietary vitamin D, where there is clear potential for overdosing.\n<\/p><\/blockquote>\n

For those who have not attended the recent session of the AAAAI in Washington, here is a possible and rather simple explanantion of the Weiss et al. findings. Supplements may be more effective in hypovitaminic individuals, yea, yea.<\/p>\n
