Featured article prose?[edit]

Diets containing foods high in antioxidants have been shown to improve health. However, in supplement form, the prevention of diseases such as cancer or coronary heart disease and the general promotion of health has not been confirmed experimentally. Trials including supplements of beta-carotene, vitamin A, and vitamin E singly or in different combinations found no effect on mortality or might increase it.

Is there much more like this? --John (talk) 19:20, 13 May 2016 (UTC)

The first sentence John quotes is uncited and, as best as I know, a mistake. No diet high in vitamins A-C-E, the only confirmed dietary antioxidants, has been shown to improve health. The section under Health effects, Relation to diet (which is poorly organized around intake of supplements, not food), does not discuss any diet with positive health effects. Neither is there any quantitative proof that a polyphenol-rich diet improves health: polyphenols are not accepted as dietary or in vivo antioxidants, as their bioavailability is poor, their fate in vivo cannot be measured and they are rapidly excreted, i.e., the body doesn't want them in the same way it does vitamin C (water soluble, widely dispersed in high retained content) and vitamins A and E (stored in lipids). --Zefr (talk) 19:44, 13 May 2016 (UTC)
Yes, the science is wrong and the writing sub-literate. If there is a lot like this in the article it had better be improved or we would need to consider reviewing its status. --John (talk) 19:50, 13 May 2016 (UTC)
