swmum If I have understood this correctly, the report you linked to was mis-reported, and here's how.
The study (full text of the study, not an article misunderstanding it is here for you to read exactly what it really does say)
It compared two groups not three. The ' High nutrient group' had enriched formula. The 'Standard nutrient' group was a mixed bag of babies who had been fed either unsupplemented donated banked breast milk or a standard term formula. Note - they didn't actually distinguish between the two!!!! They just chucked the standard-formula-fed and banked-milk-fed results together, to compare against the enriched formula results!
You can see how this is a bit right?
It's like feeding one group a diet of apples and onions, and the other a diet of oranges. And then concluding that oranges are better than apples. Not possible to conclude that unless you can seperate out the apples from the onions, IYSWIM?
Oh, and they only used 76 babies (in comparison to the many many studies out there that use thousands of babies.)
The journalist who wrote the BBC article should have been able to understand what the conclusion actually was, and the flaw in the construction of the study. They did not understand, frustratingly.
I agree with you that reporting like this is really confusing and can lead to scepticism about who to believe. The only way to really be sure is to either read the research yourself, or decide who you are going to trust to read up and convey that message to you on your behalf.
Hint; Tiktok, Hunkermunker and Welliemum are three reliable sources that I shamelessly rely upon to do my dirty work for me . They really know their onions.
I wish you luck in your research, and more importantly, with your wee bub!
