How much funding is provided by the coffee industry for research on the health benefits of coffee?
I came across a statistic that surprised me by its meagerness. According to their website, the National Coffee Association USA has spent $6 million on research funding over the last 20 or so years. The NCAUSA cites 80 specific investigations that they funded. (I don't know if the trend is up or down over the two decades.)
From reading Antony Wild's Coffee: A Dark History a few years ago, it was my impression that the coffee industry sets great importance on demonstrable health benefits. See in particular Chapt. 14, Coffee, Science and History.
The book mentions specifically the Vanderbilt Institute for Coffee Studies as funded by "a $6 million grant from the coffee industry" to Vanderbilt University Medical Center in 1999. (In 2007 the Institute moved its affiliation from the Medical Center to the Vanderbilt Center for Latin American Studies, but continues investigating "the health effects of coffee consumption, including potential therapeutic uses".) While some of this funding came from NCAUSA, it appears the bulk came from the Association of Coffee Producing Countries (ACPC), with additional funding by the All Japan Coffee Association and the International Coffee Organization.
The global coffee commodity market has annual sales well-up in the tens of billions($), so I would expect more in annual research funding than the average $300K/yr reported by NCAUSA.
Added: Apparently it is difficult for coffee trade associations to survive. The NCAUSA cited above is ancient in comparison to other organizations mentioned. The Association of Coffee Producing Countries (ACPC) began in 1993 with a model of OPEC-like price supports through agreed upon limitations of exports, but dissolved at the beginning of 2002. So a dimension of this topic is the limited degree to which coffee producers and manufacturers are able to cooperate.
