We're gobsmacked.
They're delicious, potassium-rich and the perfect option when you're in a rush - but it turns out bananas are actually one of the worst things you can eat for breakfast.
A nutritional expert claims the fruit is too sugary and acidic to be eaten on its own, and will leave you feeling tired and hungry.
Speaking to Byrdie, Dr Daryl Gioffre, creator of the AlkaMind diet, said:
"Bananas seem like the perfect option to grab and go in the morning, but with a closer look, you'll find that bananas eaten alone aren't the best option because they're 25% sugar and moderately acidic."
"Without balancing this banana breakfast with a healthy fat, many of banana's benefits are lost, while spikes in blood sugar and acid are gained."
He explained that they'll give you a quick boost but in the long run, eating bananas on their own will set you up for cravings, fatigue, weight gain and inflammation.
You don't have to skip the fibre-rich fruit altogether though - Dr Gioffre advises pairing them with a healthy fat and/or spice.
His favourites include raw almond or coconut butter, chia, hemp, flax, cinnamon and turmeric.
"Because bananas are acidic, you'll have to neutralise the acid to get the benefits of potassium, fibre, and magnesium without the sugar rush."
