What’s happening with the dietary guidelines

I get asked all the time about what’s happening with the dietary guidelines.  I have no inside information, but am exhausted at the thought that we have to go through all this again.

By law, dietary guidelines have to be re-done every five years, even though they always say the same things: eat more fruits, vegetables, and whole grains; eat less sugar, salt, and saturated fat; balance calories.  OK.  They take take more than 150 pages to say that, but that’s what it all boils down to.

Will they be different in the new MAHA (Make America Healthy Again) era?  I can only speculate.

To review the process:

  • A scientific advisory committee reviews the research and writes a report.  This one released its report in December.
  • Now, the Departments of Agriculture and Health and Human Services appoint a committee—or somebody—to write the actual guidelines.

USDA Secretary Brooke Rollins says the two departments are working on them and they will come out “hopefully early fall.”  If they do, this will set records.  The guidelines typically are released in late December or early January.

The secretaries have promised they will not continue the tradition of “leftist ideology”  I’m not sure what tradition that is, exactly, although I suspect it means “plant-based.”

I can’t wait to see what happens with:

  • Beef: USDA has always been sensitive to the demands of beef, corn, and soybean farmers.  Suggestions to eat less beef are typically phrased euphemistically (“eat lean meat”).
  • Fats: RFK Jr wants seed oils replaced with beef tallow.
  • Sugar: USDA has always been sensitive to the concerns of sugarbeet and sugarcane producers, historically a powerful lobby.  RFK Jr says sugar is poison.
  • Ultra-processed foods:  The scientific advisory committee ducked the issue.  The MAHA folks are concerned about them.
  • Emphasis on plant foods: Will the guidelines continue to promote their health benefits?
  • Calories: The “C” word.  Will the guidelines bring back a discussion of calories, their principal food sources, and how their intake is affected by ultra-processed foods?
  • Sustainability: The “S” word.  I would guess this one stays off the table, but you never know.

This one will be fun to watch.
