Why mainstream researchers think the U.S. Dietary Guidelines lack scientific rigor
By Peter Whoriskey January 13
Eat this. Don’t eat that. Five cups of coffee a day is fine. Like most retail nutrition advice, the new issue of Dietary Guidelines for Americans is presented as if there were scientific certainty about what we ought to eat.
Here is the way the Dietary Guidelines, which federal government published last week, touts its credentials: “A growing body of research has examined the relationship between overall eating patterns, health, and risk of chronic disease, and findings on these relationships are sufficiently well established to support dietary guidance.”
Yet what many experts in nutrition research will admit is that scientific certainty on these topics is often elusive, even on the health effects of some very common foods.
Now a new paper gives some insight into the unsettled state of the science. And although this may sound like an attack on the nutrition establishment by some marginal players, it is not. It comes from the mainstream: The paper appears in the journal Circulation, published by the American Heart Association. The author is Dariush Mozaffarian, the dean of the nutrition school at Tufts University. It was funded by the National Institutes of Health.
The paper lists key ideas in nutrition concerning the links between diet and heart disease, and for each idea, describes the level of scientific consensus that underlies it. There are four levels of scientific consensus, ranging from the highest -- “broad concordance and less controversy” -- to those suggesting turmoil -- “substantial controversy and/or uncertainty” and “insufficient evidence for meaningful conclusions.”
Take, for example, the idea, included in the new Dietary Guidelines, that Americans ought to limit their intake of saturated fats to 10 percent of all calories. Saturated fats are those characteristic of animals products. Although the authors of the Dietary Guidelines argue that this is based on established science, Mozaffarian describes the the alleged harms of saturated fats as uncertain. He lists the science on that topic as having “substantial controversy and/or uncertainty.”
