For healthy eating fans, it was the All-Star Game. Pick your preferred diet — vegan, paleo, Mediterranean, you name it — and the scientist, clinician or academic behind it was at the table in Boston this week. Think Dean Ornish, S. Boyd Eaton and T. Colin Campbell.
They all gathered at the Finding Common Ground Conference, convened by the nonprofit Oldways, to hammer out a consensus on healthy eating — an antidote to what can seem like endless flip-flops on dietary research. And amazingly enough, they did.
What they found was that despite all the food fights, the prevailing theories of nutrition and healthy eating actually have more in common than you’d think. (Though it’s a bit more complex than Michael Pollan’s classic, “Eat food. Not too much. Mostly plants.”)
After two days of presentations on the latest research, debates over ethics and attempts to differentiate between nit-picky nuance and important distinctions, Harvard’s Walter Willett sums up the consensus like this in a press release: “The foods that define a healthy diet include abundant fruits, vegetables, nuts, whole grains, legumes and minimal amounts of refined starch, sugar and red meat, especially keeping processed red meat intake low.”
So there you have it. But for a more granular look, here’s my take on the 11 principles these top scientists and nutritionists agreed should be the guiding principles when thinking about what and how we eat:
1. Yes to the federal guidelines
From the consensus statement:
The Scientists of Oldways Common Ground lend strong, collective support to the food-based recommendations of the 2015 Dietary Guidelines Advisory Committee, and to the DGAC’s endorsement of healthy food patterns such as the Mediterranean Diet, Vegetarian Diet and Healthy American Diet.
The overall body of evidence examined by the 2015 DGAC identifies that a healthy dietary pattern is higher in vegetables, fruits, whole grains, low- or non-fat dairy, seafood, legumes, and nuts; moderate in alcohol (among adults); lower in red and processed meats; and low in sugar-sweetened foods and drinks and refined grains.
Additional strong evidence shows that it is not necessary to eliminate food groups or conform to a single dietary pattern to achieve healthy dietary patterns. Rather, individuals can combine foods in a variety of flexible ways to achieve healthy dietary patterns, and these strategies should be tailored to meet the individual’s health needs, dietary preferences and cultural traditions. Current research also strongly demonstrates that regular physical activity promotes health and reduces chronic disease risk.
The Dietary Guidelines Advisory Committee is a group of scientists handpicked by the government to create a report detailing nutritional and dietary guidelines. Every five years, their report is reviewed by the USDA and the Department of Human Health Services before being voted on by Congress and implemented as the American Dietary guideline — the public policy informing public school lunches, military food and food industry regulations. The official vetted guidelines are due out by the end of the year.
Along with endorsing that committee’s report, the Oldways Common Ground Committee also backed Mediterranean and vegetarian diets.
2. We have to think about the planet when we eat
Form the consensus:
We emphatically support the inclusion of sustainability in the 2015 DGAC report, and affirm the appropriateness and importance of this imperative in the Dietary Guidelines for Americans because food insecurity cannot be solved without sustainable food systems. Inattention to sustainability is willful disregard for the quality and quantity of food available to the next generation, i.e., our own children.
Background: The DGAC recommended to Congress, for the first time, that nutritional policy should take into account environmental impact. Continue reading
