Q: ive been told i cant eat cherrios or frosted mini wheats during passover because it contains wheat......but what about the whole wheat matzah that ive seen?
A: It's not the wheat which is the issue, but whether the food has leavening in it or has been allowed to be leavened (rise). Matzah, for example, has wheat but is "unleavened bread." Check to see whether Cheerios or Frosted Mini-Wheats have some kind of leavening agent, such as yeast.
