Bananas are relatively high in carbohydrates and natural sugars, and can contribute to weight gain if consumed in excess without adequate physical activity to burn off the calories.
Due to their natural sugar content, eating too many bananas can cause a spike in blood sugar levels. And, if you have diabetes, it’s important to keep your blood sugar levels as stable as possible.
Bananas are rich in fibre, which is beneficial for digestion when eaten in moderate amounts. However, consuming excessive amounts of fibre can lead to digestive discomforts such as bloating, gas, and diarrhoea.
Bananas are a significant source of potassium, and consuming too many can lead to a condition called hyperkalemia, characterised by high levels of potassium in the blood. Symptoms may include irregular heartbeat, muscle weakness, and fatigue.
Bananas contain natural sugars, which can contribute to tooth decay and cavities if proper oral hygiene is not maintained.
