I’ve been collecting examples of conflicted research for the past week or so. These are studies paid for in part by food businesses or trade associations with a vested financial interest in the outcome of the research.
These almost invariably promote the financial interests of the sponsor. To wit:
Cocoa flavanol consumption improves cognitive function, blood pressure control, and metabolic profile in elderly subjects: the Cocoa, Cognition, and Aging (CoCoA) Study—a randomized controlled trial, by Daniela Mastroiacovo, Catherine Kwik-Uribe, Davide Grassi, Stefano Necozione, Angelo Raffaele, Luana Pistacchio, Roberta Righetti, Raffaella Bocale, Maria Carmela Lechiara, Carmine Marini, Claudio Ferri, and Giovambattista Desideri.

Chronic consumption of flavanone-rich orange juice is associated with cognitive benefits: an 8-wk, randomized, double-blind, placebo-controlled trial in healthy older adults, by Rebecca J Kean, Daniel J Lamport, Georgina F Dodd, Jayne E Freeman, Claire M Williams, Judi A Ellis, Laurie T Butler, and Jeremy PE Spencer.

Dairy consumption and risk of cardiovascular disease: an updated meta-analysis of prospective cohort studies, by Li-Qiang Qin PhD, Jia-Ying Xu PhD, Shu-Fen Han PhD, Zeng-Li Zhang PhD, You-You Zhao PhD, Ignatius MY Szeto PhD. Asia Pac J Clin Nutr. 2015 Mar;24(1):90-100. doi: 10.6133/apjcn.2015.24.1.09.
In each of these cases, the sponsors got what they paid for. Recent sponsored studies have not come to conclusions contrary to the interests of the sponsor.
