Why does tea cause acidity as soon as you drink it?
Does tea directly create acid the moment it reaches your stomach? Not exactly.
Caffeine can stimulate the stomach to release more acid. If stomach pressure increases, acidic contents can also move upward into the food pipe.
Unlike the stomach, the food pipe is not as well protected against acid. When acid comes into contact with it, you may feel burning, chest discomfort, or heartburn.
So, tea-related acidity isn’t always just about “too much acid.” Both acid production and acid reflux can play a role.
