"This research was funded through a grant from The Peanut Institute Foundation (TPIF). TPIF did not participate in the study design, data acquisition or analysis, decisions regarding publication, or the writing of the manuscript."

Hmmm...

This is not an argument against trusting the study though.

(Unless the study was not preregistered, then it could be evidence of publication bias.)

You expect The Washing Machine Institute Foundation is going to sponsor it?

> During his time as the Executive Director of the American Peanut Shellers, John helped to found the Peanut Institute and the U.S. Peanut Federation. These two entities have helped to promote the interests of the peanut industry throughout the United States and the world. Moreover, John has worked on eight farm bills during his life, always advocating for those who he represented. Since 2001, John, in association with the National Peanut Board, has helped to steer more than 36 million dollars to food allergy research, outreach and education. Earlier this year, because of his significant contributions to the Peanut Industry, John was inducted into the American Peanut Council Hall of Fame.

The summary has some impressive p-values.

The results are nuts!

Would love to see this reproduced, or more explanation given to what part of the peanut causes this.

Supposedly its the L-arginine.

> In particular, peanuts contain high amounts of L-arginine, a precursor for nitric oxide synthesis, which is essential for vascular function and blood flow regulation [6,11]. Therefore, this may represent a mechanism by which peanut consumption could positively influence cognitive performance through improvements in CBF. Furthermore, peanuts are a rich source of unsaturated fatty acids and polyphenols, both of which have been shown to support vascular health [12].

And there do seem to be papers that associate these two according to a quick google search (plus it's cited of course).

interesting!
