If it's an excess of acid that's causing inflammation in the oesophagus or stomach, then milk may help. That’s because milk coats the lining and buffers the acid inside your stomach.
Milk can also help to quell the burning sensation of spicy foods like chilli. The chemicals in spicy foods like capsaicin (chillies) or piperine (pepper) activate pain receptors that send signals to your brain, allowing you to interpret the spicy sensation of chilli.
Therefore, spice not only affects the taste buds but also certain exposed membranes like your nose, under your fingernails or the surface of your eyes. That’s when milk can help, by slowing down the chemicals and allowing the receptors to go back to normal.
