Raising agents - bicarb and baking powder

Now if I have this right, Americans call it baking soda and Australia calls it bicarbonate of soda (bicarb for short). And baking powder is bicarb with something else, usually cream of tartar.

Are any of those things to avoid as migraine triggers?

What about self-raising flour? That’s just flour with baking powder, isn’t it?


I know of no reason to be concerned about them. Now if you had Meniere’s, you might seek a sodium free alternative.
