True and important. But this particular study doesn't seem to be an instance of that phenomenon. So far as I can tell, no one involved was funded by the food industry, and what they did was to look broadly for connections between diet and cognitive function and this turned up. Now, there are other problems with that sort of data-mining and determining whether they've successfully avoided them all is highly nontrivial (and I haven't tried). So this might still be bad science. But it doesn't appear to be funded-by-vested-interests bad.
