Do we need a big intervention study on whole grains?
Simin Liu, professor of epidemiology & medicine at Brown University, said it would be perfectly possible to design an intervention study to determine if whole grains were as beneficial as the observational data suggests, noting that it would probably cost $350-400m to put together a four year study with 5,000-10,000 participants. However, others in the room reckoned the money would be better spent on trying to increase whole grain consumption.
