According to doctors, bananas, although they are full of potassium and vitamin B6, as well as being free of cholesterol and sodium, are not ideal as their first meal.

Nutritionist Daryl Geoffrey explained that while bananas seem like a good option in the morning, they're not good for maintaining your energy levels throughout the day.

"Bananas are not the best option because they contain 25 percent sugars and moderate acidity, they will give you a quick boost, but you will soon get tired and feel hungry."

"Without balancing a banana breakfast with healthy fats, many of the benefits of bananas will be lost, while blood sugar and acids are increased," Jeffrey continued.

"It is advisable to combine bananas with something that will neutralize the acid to get the benefits of potassium, fiber and magnesium, and slow down sugar metabolism, which should prevent high blood sugar."
