Myth-buster
Anthocyanins showed no link to lower obesity odds in a meta-analysis of 302 people — even as total flavonoids and isoflavones did in a much larger analysis.
This tells us that, so far, the evidence for anthocyanins specifically is weak and inconclusive; don't treat this single small meta-analysis as the final word, but it does pop the bubble of any hype that 'all polyphenols work the same' for weight.
Researchers pooled data from 10 studies covering over 106,000 people and found that higher intakes of total flavonoids and isoflavones were tied to lower odds of obesity. But when they zoomed in on anthocyanins, flavones, flavanones, and flavanols, no statistically significant association emerged — the analysis for anthocyanins involved only 302 participants, so the null result may reflect low statistical power rather than a definite absence of effect.
Where this fits in the evidence
This is among the first studies we've indexed on Anthocyanins for Reduced Obesity — treat it as an early signal until more research accumulates.
