Asthma Risk and Vitamin C
You’ve probably seen reports that asthma rates in the U.S. are on the rise. Researchers are trying to determine why. I’m heartened to see that diet and, specifically, nutrient intake, are among the factors being considered.
Researchers reported in the May 2006 edition of the journal Thorax that they compared diets of healthy control subjects with those of asthma patients, some experiencing symptoms, and some not having had symptoms for the last year.
What I found most interesting in the Reuters Health account of this research was that compared to asymptomatic asthmatics, “Lower intake of both vitamin C and manganese were tied to an increased risk of symptomatic asthma”. Also, “…symptomatic asthma patients had significantly lower levels of plasma vitamin C than healthy controls.”
