Ans: Acidity is quite a common disorder these days, and we have learnt to live with it and usually find cures rather than precautions.
There are multiple reasons for acidity, sometimes so severe that it leads to heart burn. It is named so, as the oesophagus, where the burning sensation is felt, lies just behind the heart.
The first step is to better understand your body type -- what agrees with your digestive system and what doesn’t.
Secondly, it’s the quantity. Always eat so your stomach is half full. And it is about timing -- heavy meals during the day and light or no food after sunset.
Once you understand these principles, you will be able to balance the acid refluxes and avoid severe acidity or heartburn.
