After having a mild heart attack, my Dad started drinking his coffee black. He would swear omitting cream & sugar from his coffee caused him to lose weight, completely disregarding other changes to his diet and lifestyle.
But, in Clod's case she has been closely monitoring every god damn molecule that her kids ingest, for a long time. She's also been monitoring output and behavior.
So unlike my Dad, and unlike UT's examples, Clod has valid results of what works for her kids. And that's what this is about, not medical research, just what works for her kids. Go Mom.
