TerriLynn, it was actually my sister who discovered this. She was going thru an issue and she HAD to eat a bowl of cheerios every day so the oat fiber would kickstart her (clears throat) "system" each day. Without the cheerios, she became .... oh heck let's get it in the open..... constipated. She bought the generic ones in the bag and her system didn't work right. that's when she discovered she was only getting about half of the oat fiber because the generics were mostly air.
The things we learn in life, huh!
I don't care how much they try to tell us, generics are different. There has to be a reason why they can make it cheaper, not just because you are paying for the brand.
For example, Rice Krispies are made with sugar, the store brand I can get uses HFCS. I have a box of the generic waiting to be tossed because I won't use it and I won't let my family eat it. I should have read the ingredient list first, which I do now!
