The Claim

In middle-aged women with metabolic syndrome risk factors, high resistant starch intake for 8 weeks is associated with a modest but statistically significant reduction in systolic blood pressure, independent of changes in body weight or caloric intake.

In plain English

Middle-aged women with metabolic syndrome risk factors who consume high amounts of resistant starch for 8 weeks experience a small but measurable decrease in systolic blood pressure, even when their weight and calorie intake do not change.

See the scientific wording

In middle-aged women with metabolic syndrome risk factors, high resistant starch intake for 8 weeks is associated with a modest but statistically significant reduction in systolic blood pressure, independent of changes in body weight or caloric intake.

Why this might work

Eating more resistant starch feeds gut bacteria that produce short-chain fatty acids. These fatty acids enter the blood and bind to receptors on blood vessel walls, causing the vessels to relax and widen. This lowers the pressure inside the arteries.

  1. Study: Effects of Resistant Starch on Metabolic Markers and Gut Microbiota in Women with Metabolic Syndrome Risk Factors: A Randomized, Double-Blind, Pilot Study

    In a study, women who ate more resistant starch for two months had slightly lower blood pressure, even though they didn’t eat fewer calories or lose weight. So yes, the starch helped lower blood pressure on its own.
