There was a report last week casting doubt on advisability of using antioxidant supplements and perhaps even a diet that incorporates quantities of antioxidant foods.....
"Though researchers only examined the effects of vitamin E and NAC, they cited a body of evidence that suggests that other antioxidants may also fuel cancer cells, not thwart them. According to the National Center for Complimentary and Alternative Medicine (NCCAM), clinical trials of antioxidant supplements have repeatedly failed to prove claims that they help prevent conditions like heart attacks, strokes, dementia, or cancers.
'If anything, if you look at all of them, antioxidants do not protect against cancer. They may increase the risk,” lead researcher Martin Bergo of the Sahlgrenska Cancer Center told reporters this week.
The researchers say their findings suggest that antioxidant therapy is unsafe for smokers, patients with early-stage lung cancer, and people with COPD. However, they said their study only addressed the impact of antioxidants on tumor progression, not initiation or prevention.'
Acknowledging that more studies are needed, Bergo agreed that antioxidants should be used with care in persons with lung cancer or those at a high risk of developing it."

Many friends have offered 'dietary' advice for my wife's lung cancer treatment, almost all of which suggests use of antioxidants. Is all the green tea and kale she's ingesting not only useless, but perhaps even dangerous?
