Question

If someone you know is very sensitive to acid foods, which foods would you recommend he or she avoid?

Answer 1

Most fruits, like oranges, lemons, limes, etc. contain citric Acid. So...tell them to stay away from that stuff.

I believe milk contains lactic Acid, I.e. lactose/lactate. That could probably be avoided. (Although, the amount may not be high enough to be relevant)

There’s no telling how many other foods contain Acid.
