Food companies distort nutrition science by funding studies. That's why we have very specific titles like "Concord grape juice, cognitive function, and driving performance," or, "Walnut ingestion in adults at risk for diabetes." Usually the results are positive. http://www.vox.com/2016/3/3/11148422/food-science-nutrition-...
That has absolutely nothing to do with this study.
It's the only reason this study exists, or got the results it did.
