I have a terrible burn feeling in my chest after I eat certain foods.

Best to search for the root cause. If it is acid reflux, what is causing the acid: Too much acid or NOT enough or not at the right time. Acid reflux might be masking a different condition. For example, taking anti-acids may actually be making the situation worse. Your body is generating acid for a reason (it thinks there food in your stomach or upper GI). Or you may have bad stomach flora. Or those tomatoes were not properly washed/prepared. Or you may have some unresolved emotional tension. Or . . .

In my case, at times, when I get that feeling, it's my body trying to generate acid to digest the food, but doesn't generate enough at the time the food was eaten. So I help it along by drinking a mild vinegar solution (1 vinegar to 4 water) and in about 10 min food is digested and I'm back to normal. P.S. In addition, vinegar helps give you a full -- eaten enough -- feeling so you don't want more food.

Are you drinking any kind of non-water products (i.e. colas, coffee with non-dairy creamer, or especially diet drinks), they could be triggering the reaction.

Find our the root cause and correct it.

Try unsweetened almond milk, soy, dairy,gluten free. 1 carb per cup and it's alkaline which is good you.
I use it as creamer in my low acid coffee in the morning. Great in Cheerios too!
