Short answer: not exactly — but here’s what the science actually shows.
There is no current USDA designation that formally ranks foods as “#1.” However, in USDA-published antioxidant research, aronia (black chokeberry) was found to have among the highest antioxidant levels of any fruit tested.
In a large antioxidant survey conducted by USDA scientists, aronia measured nearly four times the antioxidant capacity of blueberries using the ORAC (Oxygen Radical Absorbance Capacity) method.
Because ORAC is a laboratory measurement — and not a health claim — the USDA later removed it from consumer databases to prevent misuse in marketing. The underlying research, however, remains peer-reviewed and scientifically valid.
What this means:
Aronia was not “officially crowned” #1 by the USDA, but USDA-affiliated research consistently places it at the very top of antioxidant-dense fruits ever measured.
