In an international review published in Hypertension led by Monash University scientists, biologists have highlighted the pivotal role of dietary fibre in managing hypertension and reducing cardiovascular disease (CVD) risk. Researchers are calling for the inclusion of dietary fibre in clinical guidelines for hypertension.
“Despite numerous guidelines recommending lifestyle modifications as first-line treatment for hypertension, specific recommendations regarding fibre intake have been notably absent,” said lead study author Associate Professor Francine Marques from the Monash University School of Biological Sciences.
“Dietary fibre has emerged as a crucial yet underappreciated part of hypertension management,” she said.
“Our comprehensive analysis emphasises the evidence supporting the effectiveness of dietary fibre in lowering blood pressure and reducing the risk of cardiovascular events.”
The findings of the review have significant implications for public health initiatives and future hypertension guidelines.
By recognising the vital role of dietary fibre, healthcare professionals can take proactive steps to address hypertension and promote cardiovascular health.
The study found that a higher intake of dietary fibre is associated with a significant reduction is systolic acid and diastolic blood pressure, independent of pharmacological interventions. Each additional 5 grams of fibre per day is estimated to reduce systolic blood pressure by 2.8 mmHg and diastolic blood pressure by 2.1 mmHg.
The review also provides resources for medical teams and patients of what foods to prioritise to increase fibre intake and reach their recommendations.
“Our study highlights the urgent need for healthcare providers to prioritise dietary fibre as vital for hypertension management,” Associate Professor Marques said.
“By incorporating dietary fibre into treatment plans and empowering patients to increase their intake, we can significantly reduce the burden of hypertension and improve cardiovascular outcomes.”
