The FDA is proposing a new “Nutrition Info” box for the front of packaged foods — a small label rating saturated fat, sodium, and added sugars as “Low,” “Med,” or “High.” But a landmark trial published in March 2026 reveals a serious flaw: the format causes shoppers to misidentify candy bars and processed meat as healthy choices. If you want to make genuinely informed choices at the store today, knowing how to read a full nutrition label — not just the front-panel shortcut — still matters.
What the Study Found
Researchers at UC Davis tested more than 13,000 U.S. adults across multiple label formats. Participants shown the FDA’s proposed “Nutrition Info” box — which displays “Low” ratings for whichever of the three nutrients falls below thresholds — frequently rated products like candy and processed meats as healthier options overall. The effect, which the researchers call a “false health halo,” appears to stem from the prominence of multiple “Low” badges: seeing even one or two “Low” ratings primes shoppers to view the entire product favorably, regardless of what else is in it. The study was published on March 24, 2026, in the journal The Lancet Public Health, according to UC Davis.
What Researchers Recommend Instead
The UC Davis team, led by epidemiology Ph.D. candidate Brittany Lemmon and associate professor Jennifer Falbe, found that a simpler “High In” design outperformed the FDA proposal for helping shoppers identify less healthy options. Under that approach, a label would only appear on a product when a nutrient exceeds a concerning threshold — for example, “High in Added Sugars” or “High in Sodium” — rather than displaying a grid of Low/Med/High ratings for all three nutrients at once. The absence of any label would signal a product is not problematic on those dimensions, which participants found easier to interpret correctly.
Why This Matters for Shoppers Now
The FDA’s final rule on front-of-package labeling had been projected for spring 2026, but as of this writing remains pending, with tens of thousands of public comments still being reviewed. Large food companies would have three years from any final rule to comply. Until a well-designed label reaches store shelves, shoppers navigating packaged foods are on their own — and a “Low Sodium” badge on the front tells you nothing about added sugars, refined carbohydrates, or ingredient quality hiding further down the panel.
