Key result
A healthy diet reduced systolic blood pressure by 9% compared to a control diet at 12 weeks in overweight and obese individuals, while psyllium fibre supplementation did not significantly improve blood pressure at 12 weeks.

Prioritize healthy diet for SBP reduction in overweight/obese adults; confirms dietary efficacy while challenging psyllium benefits.
Pal et al. (2011) conducted an RCT in Overweight and obesity (n=72). Psyllium fibre supplementation or healthy diet vs. Placebo with usual diet was evaluated on Systolic blood pressure at 12 weeks (Healthy diet vs Control) (9% reduction, p=0.02). A healthy diet reduced systolic blood pressure by 9% compared to a control diet at 12 weeks in overweight and obese individuals, while psyllium fibre supplementation did not significantly improve blood pressure at 12 weeks.
