Nancy, you don't know how to read or assess research, that much is clear.
You have moved from diabetes to the debate on intelligence and breastfeeding - the study you quoted from the Independent report is one of many, and the research on bf and intelligence is fraught with pitfalls because intelligence, unlike diabetes, is hard to measure. There are many studies - including ones more recent and more powered (in the statistical sense) than the one you quote - that show a strong link, in fact, but because of the slippery and culture-bound nature of intelligence, you'd expect variable results between studies. There are no studies that show intelligence is lowered by breastfeeding of course, and plenty that show the opposite effect. If we're weighing research, then it's pretty obvious which way the scales are tipped.
Nevertheless, it's a lot easier to demonstrate a consistent link between something that's medically diagnosable.
Obesity and type 2 diabetes have both been shown in many studies to be linked with how people are fed at 3 mths. But clearly you prefer not to accept this link, though I don't know why.
