oilk is often suggested as a remedy for heartburn as its alkaline content was thought to neutralise the acid that causes burning in the oesophagus.
However, researchers say that while it may help to ease that burning sensation when you drink it, the relief is only temporary. It can actually have a rebound action that may encourage your stomach to produce extra acid. If you drink it before bed, it could end up causing acid reflux while you’re asleep.
