The
antioxidant effect of pomegranate juice: There is a great deal written about the protective effect of antioxidants these days. Because of high levels in fruits and juices their consumption tops the list of those with the most benefit. One fruit juice with an abundance of antioxidants is pomegranate juice (PJ). In the test tube pomegranate juice has over three times the antioxidant activity of red wine or tea.
The
stress of oxidation plays a large role
in the decline of lung function in people
with emphysema. To evaluate whether the
antioxidants in pomegranate juice are effective for patients
with this high stress condition, scientists had two groups drink
either PJ or a PJ flavored placebo for 5 weeks (Eur.
Journ. Clin. Nutr. 2006; 60: 245 - 253). They then evaluated lung function
as well as total antioxidants in the bloodstream.
No difference was found between those drinking juice and those using placebo. Not only were there no differences in lung function but there wasn’t a significant rise in antioxidants in the blood stream of participants. It appears that the most important of the antioxidants was processed in the intestine and never absorbed.
What this means for you: Pomegranate juice tastes good and the antioxidants in it may be effective for some conditions--but not for emphysema.
