I know this is an older post but I am glad that I found this thread in an internet search. I am finally realizing that my months of vertigo are related to eating white rice hot cereal each morning. I even went to a vertigo specialist who did Epley Maneuvers which did not help.
When I took a break by eating grain-free and then resumed by eating a bowl of white rice hot cereal (hey, it’s comfort food for me), I had a bad spell of dizziness. The next day (still not making the connection), I ate a snack of black rice crackers. Awful vertigo. Found out this morning that individuals w/ sensitivity to oats and even gluten-free oats are very likely going to have issues with black rice due to the special ‘bran” shared by black rice and oats. So the answer for me is yes, rice can cause dizziness or vertigo.
