On the other hand, you may instead argue: What right has the federal government to propose that the American people conduct a vast nutritional experiment, with themselves as subjects, on the strength of so very little evidence that it will do them any good?

Mr. Chairman, resolution of this dilemma turns on a value judgment. The dilemma so posed is not a scientific question; it is a question of ethics, morals, politics. Those who argue either position strongly are expressing their values; they are not making scientific judgments.

Though the conflict-of-interest accusations served to discredit the advice proffered in Toward Healthful Diets, the issue was not nearly as simple as the media made it out to be and often still do. Since the 1940s, nutritionists in academia had been encouraged to work closely with industry. In the 1960s, this collaborative relationship deteriorated, at least in public perception, into what Ralph Nader and other advocacy groups would consider an “unholy alliance.” It wasn’t always.

As Robert Olson explained at the time, he had received over the course of his career perhaps $10 million in grants from the USDA and NIH, and $250,000 from industry. He had also been on the American Heart Association Research Committee for two decades. But when he now disagreed with the AHA recommendations publicly, he was accused of being bought. “If people are going to say Olson’s corrupted by industry, they’d have far more reason to call me a tool of government,” he said. “I think university professors should be talking to people beyond the university. I believe, also, that money is contaminated by the user rather than the source. All scientists need funds.”

Scientists were believed to be free of conflicts if their only source of funding was a federal agency, but all nutritionists knew that if their research failed to support the government position on a particular subject, the funding would go instead to someone whose research did. “To be a dissenter was to be unfunded because the peer-review system rewards conformity and excludes criticism,” George Mann had written in The New England Journal of Medicine in 1977. The NIH expert panels that decide funding represent the orthodoxy and will tend to perceive research interpreted in a contrarian manner as unworthy of funding. David Kritchevsky, a member of the Food and Nutrition Board when it released Toward Healthful Diets, put it this way: “The U.S. government is as big a pusher as industry. If you say what the government says, then it’s okay. If you say something that isn’t what the government says, or that may be parallel to what industry says, that makes you suspect.”
