Of course mothers should have more information about formula feeding.
HPs are 'not allowed' to recommend brands (although they do, all the time, and it's almost always Milupa because of the massive promotion to hps of this brand - massive because it is less well-established than the other major brands and needs the extra 'boost').
Reason they can't recommend? Nothing to do with suing by the formula makers who would love to be recommended more, but because they do not have the info to recommend one brand above another - there is no independent research that could possibly evaluate the different brands.
I would welcome this research, in fact, because I want mothers who formula feed to be able to choose milks, and not be left floundering, choosing between fluffy-wuffy bunnies on the can, or cutsie-wootsie ducky-wuckies. Or choosing Brand X because that's what their own mum used (even though the formulation might be different nowadays).
There might be some mothers who decide that they don't want synthetic ingredients in their formula - they might prefer prebiotics made from algae rather than fish eyes, for example. Or they might like to know that the high sucrose content of soya formula is probably damaging to their baby's dental health. Or perhaps they might like to know that some speciality formulas have as their main ingredient glucose syrup, or that the 'starch' added to it is actually potato starch. Yum. You can of course check the list of ingredients to get some of this info (that's how I found out about the glucose syrup being the main ingredient in that brand) but the info is not fully there. The potato starch is just 'starch' on the packet list - I know it's potato because I read the manufacturers' info to HPs.
They might like to know the paucity of research that goes into these ingredients, too, and how babies on formula are not followed up to see if these ingredients cause health issues further down the line.
All the advertsing is selective with its facts - that's what advertising does.
Mothers who choose to formula feed are pitifully under-informed and that's a scandal.
Of course there are mothers who have no choice but to formula feed and they deserve as much non-commercial info as they want.
