Am I allergic to Grape Nuts?


I ate a bowl of Grape Nuts with water to drink and milk.

I felt my chest get tight like heartburn…..but Grape Nuts gives no such burn?

So what of the 3 things I ate caused this? Water - nope, drink it often without ill result. Milk? Good guess, but i had the milk with my coffee 2 hours before the cereal, no ill result.

Therefore, I’m down to the Grape Nuts. I recall that after eating them at night I’d wake up with that tight feeling – I’m wondering if it’s a celiac sprue type thing.
