A doctor has warned that people taking common medications for high blood pressure or heart failure may be putting themselves at risk by consuming bananas. Dr Chris Steele, speaking on ITV's This Morning programme, explained that bananas are high in potassium and can interfere with ACE inhibitor drugs such as captopril, enalapril, and fosinopril.
ACE inhibitors work by blocking the angiotensin hormone, allowing blood vessels to widen and relax, thereby reducing blood pressure. However, consuming potassium-rich foods like bananas alongside these medications can lead to hyperkalaemia, a condition where potassium levels become too high. Symptoms include irregular heartbeats and palpitations.
Dr Steele advised patients on ACE inhibitors to avoid eating large amounts of high-potassium foods and to inform their GP if they are also taking potassium supplements or diuretics. He also noted that other foods and drinks, such as milk with certain antibiotics, can cause similar interactions.
The doctor emphasised the importance of consulting a healthcare professional about dietary precautions when starting new medications to avoid undesirable side effects.
