Not sure PZ, I read it as it's good to avoid saturated fats in our diets wherever we can and that is why they have made the recommendation. My understanding has always been that before 2 fat is essential for brain development, so their bodies use it differently, but after that age the fats don't get processed the same way

I also don't really get where this whole thing about low/reduced fat milks having heaps of sugar in them comes from. I drink Physical No fat and it has 13.5g of sugars per 100ml, while DS's full cream organic milk has 12g. Yes the no fat one has a little more, but 1.5g isn't that much.
Okay I definitely admit I don't know anything on the subject Very interesting to read though, I had never heard about switching so I guess it's just another one of those parenting choices down the line, I'll need to read more about it Good to know though!
