A controversial article on red meat had an unintended consequence: it unmasked the ties between science and industry. Not the meat industry, but the "anti-meat" health-advocacy industry, which reaches into academia and commercial interests. JAMA takes a stance. Good for them, which is good for us.

Errors in our scientific beliefs are not always due to Big Industry and its evil intent. Science is a human enterprise, constrained by human foibles. Sometimes we just get it wrong.
