A recent study (J Ma et al. Gastroenterol 2018; 155: 107-17) shows that a “better diet” was associated with less liver fat.
Among the 1521 participants form a Framingham Heart Study cohort (Mean age 51 years at start of study), the authors assessed diet with a 125-item Harvard food frequency questionnaire and liver fat using liver-phantom ratio (LPR) on CT images between 2002-2005 and then again 2008-2011. They specifically looked at 2 diet scores:
- Mediterranean-style diet score (MDS)
- Alternative Healthy Eating Index (AHEI)
- For each 1 standard deviation increase in MDS, the LPR increased (less liver fat) by 0.57 and the odds for incident fatty liver decreased by 26% (P=.002)
- Similarly, for each 1 standard deviation increase in AHEI, LPR increased by 0.56 and the odds for incident fatty liver decreased by 21% (P=.02)
My take: This study shows that Improved diet quality over 6 years was associated with reduced liver fat accumulation
- Proof that diet change improves fatty liver
- Six years later -Mediterranean diet comes out on top
- Heart-healthy Mediterranean Diet
