Diet quality attenuates the association between flavonoid intake and hepatic steatosis risk in the Framingham Heart Study

< 0·05), with up to 40 % reduced odds at the highest quartiles before adjustment for diet quality. After adjustments, associations attenuated and lost statistical significance. The attenuation does not rule out a potential protective role of flavonoids; it may indicate that higher flavonoid intake is an important element of a broader healthy diet. Alternatively, the associations could be confounded by other components of diet which may independently reduce steatosis risk. Nonetheless, these findings underscore the importance of promoting flavonoid-rich diets in the context of overall healthy diet and support further investigation in prospective and interventional studies targeting MASLD prevention.
