You can eat bananas. Some people think that because bananas contain more magnesium, if they are eaten on an empty stomach, the magnesium content in the blood will suddenly increase, leading to imbalance of magnesium and calcium in the body and affecting heart function. In fact, it is leafy vegetables that contain more magnesium than bananas. No one has ever said that eating leafy vegetables on an empty stomach will lead to excessive magnesium intake and affect heart function. Therefore, this statement has no corresponding scientific basis and is incorrect.
