Whilst we all love a good cup of tea in the morning, drinking tea on a completely empty stomach is not the best idea. Tea is slightly acidic and drinking tea on an empty stomach is thought to potentially affect the balance of acids and alkalis in your stomach.
Tea leaves contain tannins, which are the source of the slightly bitter taste associated with tea. However, tannins on an empty stomach may potentially make you feel a bit nauseous.
The bottom line is that you can absolutely enjoy your morning cuppa – just make sure you eat something alongside it.
