I recall advice that I was given from an Endocrinologist that if it originated from an animal moderate or stay away from it.

I ask him "what about fish"?

His reply; "Do fish swim"?

A bowel of oatmeal has been the norm for the past year or so. Very little bread or red meat.

Salt (sodium) is very restricted!

Hard to leave the mooo out of the mix!

Oatmeal was once referred to as wall paper paste! You will have to work past that!

Remember Ellis's A,B C's, it isn't what it is, but rather your "B" (belief) about it.
