Allergy to sweet potato equal allergy to any potato products?

[Guest guest]

Hi.

Does an allergy (per OATS):

- to sweet potato mean we should avoid all potato products too?

- to lemon mean to avoid all orange products too?

- to cane sugar mean to avoid honey too?

Is there a different between bakers yeas and just yeast?

I haven't had a straight answer from anyone so far. Please help. My son is

allergic to so

many things I don't know what to feed him anymore.

Thanks.
