As a fellow resveratrol researcher, I can add the following comments.
The biggest name in the field, David Sinclair of Harvard Medical, when
asked to comment on the scandal, responded that he'd never heard of Das.
This is indicative of his niche status within the field. His data,
now completely discredited, bore on the role of resveratrol in
preventing heart disease. OTOH, the role of resveratrol in combating
Alzheimer's, Parkinson's, cancer and diabetes has not, to my knowledge,
been in the least affected. Parenthetically, Dr. Sinclair's famous
results showing that resveratrol increased the activity of SirT1, an
enzyme implicated in life extension, has been shown to be artifactual,
too (but not fraudulent).
