Rice Allergy - Is Rice Allergy Becoming A More Commonly Seen Allergy?

Both my son and daughter have food allergies and my son also has FPIES (food protein-induced entercolitis syndrome). One allergy of his that we became aware of this past week is rice. It is not usually a common food for people to be allergic to, but according to this link it is on the rise:

Rice Allergy - Is Rice Allergy Becoming A More Commonly Seen Allergy?

Although I am glad to have figured out which food was the culprit, it is not an easy allergy to deal with when he already can't consume dairy, eggs, peanuts, almonds, and soy. It is a good thing he mostly drinks hemp milk! So many of the products for people with dairy, gluten, and soy allergies have rice flour as the substitute.

If you have some favorite products for people who suffer from these same food allergies, I would love to hear about it!
