A recent study suggests that increasing potassium intake from foods like bananas and broccoli, rather than just reducing salt consumption, could be more effective in reducing high blood pressure.

A new study conducted at the University of Waterloo in Canada revealed that increasing the ratio of potassium to sodium in the diet may be more effective in lowering high blood pressure compared to only reducing sodium (salt) intake. The research team highlighted that potassium-rich foods such as bananas and broccoli could positively impact blood pressure. HIGH BLOOD PRESSURE, A GLOBAL ISSUE

Affecting more than 30% of the adult population worldwide, high blood pressure is a major contributor to serious health problems like heart disease and stroke. Additionally, it can pave the way for conditions such as kidney failure, heart rhythm disorders, and dementia. “REDUCING SALT MAY NOT BE ENOUGH”

Anita Layton, a Professor of Applied Mathematics, Computer Science, Pharmacy, and Biology, stated, “When facing high blood pressure, we are usually advised to consume less salt. However, our research suggests that adding potassium-rich foods to the diet may be more effective.” AN EVOLUTIONARY APPROACH: OLD DIETS, NEW ISSUES

Lead author of the study, Melissa Stadt, mentioned, “Early humans consumed plenty of fruits and vegetables. Therefore, our bodies may have evolved to function based on a high potassium and low sodium ratio.” According to Stadt, modern Western diets often contain high sodium and low potassium levels, which could explain why high blood pressure is more prevalent in industrialized societies. MEN AT HIGHER RISK BUT MAY EXPERIENCE GREATER BENEFITS

Using mathematical models, the study demonstrated that gender also plays a role in this interaction. The findings indicate that men are more susceptible to high blood pressure but can benefit more from an increase in potassium/sodium ratio compared to women.

Researchers emphasize that these mathematical models allow for a rapid, cost-effective, and ethical examination of the effects of different factors on the human body.
