Is it true that if you eat too many bananas, they can make you nauseous?

Yes, it is true that eating too many bananas can cause nausea. Banana contains a chemical called cyanide which causes the body to produce an enzyme called rhodanase which breaks down cyanide into thiocyanate. Thiocyanate is toxic to the body and can cause nausea when ingested in large amounts. So it is true that eating too many bananas can cause nausea.
