That is a very strong point with the argument. What I would want to see more of is some analysis of the kind of studies that are cited like was the study observational or experimental? Was it done on large groups or small groups? That would impact just how solid the evidence really is. Also, since Abbott is a health firm with a stake in nutrition products, a little extra skepticism about potential bias in how they present conclusions would strengthen your fact-check. Overall, though, this is a good, thought out and well-documented analysis!
