Cholesterol Lowering Yogurt

I want to change the fiber because it has fewer calories and more fiber per serving. Oats dropped my cholesterol LOT. Will I get the same benefit of Fiber One? I like the mixture of nonfat yogurt for breakfast. Thank you!

tried many products and so looked at the food, never worked, ended up having to go on medicine.
Ultimately we are all different, try these things, then a blood test.
