Higher dietary resistant starch intake is NOT significantly associated with reduced cardiovascular disease (CVD) mortality.

Do not rely on resistant starch alone to protect your heart. This study found no significant link between RS intake and reduced cardiovascular mortality. While RS may offer other benefits, managing overall cardiovascular risk requires a holistic approach including blood pressure, lipid management, and overall diet quality, not just increasing RS.

GoodRefutesHIGH confidence
The multivariable-adjusted HRs for CVD mortality... per quintile increase in RS intake were 1 (95%CI, 0.97–1.04)... The associations remained similar in the subgroup and sensitivity analyses.

Why this rating

Large sample and rigorous methods, but the null result might be due to insufficient RS intake levels in the population rather than a lack of efficacy.
