A recent study conducted by the University of Waterloo suggests that incorporating bananas into one’s diet to increase dietary potassium levels could play a crucial role in lowering high blood pressure, surpassing the impact of simply reducing sodium intake.
With approximately a third of adults worldwide experiencing high blood pressure and its associated health risks such as heart disease, stroke, kidney issues, and dementia, conventional medical advice has typically steered individuals towards a low-salt diet to manage sodium levels in the body.
Published in the American Journal of Physiology-Renal Physiology, the study recommends the addition of bananas to one’s daily food intake, along with moderating salt consumption, as a potentially more effective approach to managing blood pressure.

Anita Layton from the University of Waterloo, a co-author of the study, explains, “Usually, when we have high blood pressure, we are advised to eat less salt. Our research suggests that adding more potassium-rich foods to your diet such as bananas or broccoli might have a greater positive impact on your blood pressure than just cutting sodium.”
According to Surrey Live, electrolytes like sodium and potassium are critical for various bodily functions, including muscle movements, maintaining fluid balance, and transmitting electrical signals throughout the body.
The findings propose that a higher ratio of potassium to sodium intake could be a more beneficial strategy for reducing blood pressure than simply reducing sodium consumption.
While previous research has highlighted the positive effects of a potassium-rich diet on blood pressure control, recent findings provide new insights into the significant advantages of a balanced electrolyte strategy. However, the optimal potassium-sodium balance for health is yet to be determined.
The study employs a gender-specific mathematical model to examine how the potassium to sodium ratio impacts physiology, simulating different body levels of these minerals and their influence on blood pressure.
Men are shown to be generally more susceptible to hypertension than premenopausal women, but it is also suggested that they might derive substantial benefits from increased potassium consumption relative to sodium intake.
The innovative modelling technique used in the study has the potential to facilitate swift and ethically responsible research into the effect of various factors on bodily functions, as highlighted by the study’s authors.
“Early humans consumed a lot of fruits and vegetables, and as a result, our body’s regulatory systems may have evolved to function best with a diet high in potassium and low in sodium,” notes Melissa Stadt, a contributing researcher.
Stadt further points out that the high prevalence of hypertension in industrialized societies, as opposed to isolated ones, may be attributed to modern Western diets, which often feature an inverse balance—high in sodium and low in potassium.
