Needless to say my grandad had a life time of eczema, my grandmother had milk intolerance and couldnt eat a warm loaf of bread!
Wow, sounds like I dodged a bullet.
Hmm. I am not so sure it makes that much difference in the end. There will always be people who are living embodiments of that theory, but for every handful there are probably thousands more who aren't.
BFing was pretty unfashionable and increasingly uncommon in the UK throughout most of the 20th century. Formula is blamed for an awful lot of illnesses and allergies and of course obesity and while I don't doubt there is a connection, I do think it tends to be overplayed by staunch BFing advocates. Likewise I think the apparently proven benefits of BFing are vastly overplayed, once the problem of poor hygiene in FF is taken out of the equation.
There are several generations of adults walking around now in the UK for whom the majority were probably FF (or given some early version/vague approximation of modern formula according to whatever was available and considered suitable at the time) as was the cultural norm. The majority of them don't have allergies or serious intolerances, the majority haven't carried obesity with them from early childhood, the majority don't have diabetes and we know that the burgeoning problem with type 2 diabetes is much more to do with an over-reliance on a ready supply of high carbohydrate processed junk foods and poor lifestyle choices, lack of exercise etc., in later life rather than how our mother fed us as a newborn.
Some of the countries seeing the sharpest rises in obesity and diabetes rates now are developing countries where BFing is and always has been the norm for the majority.
In addition, I'll bet there are still plenty of children who have been EBF and weaned onto solids just in time to take their driving test by well educated, well intentioned, middle class mothers who pride themselves on doing it all 'properly' who still go on to develop asthma, eczema, reflux, lactose intolerance, chronic constipation, IBS and a whole gamut of food allergies and intolerances. And while FF children are more likely to end up overweight than BF children, I really do think that far more about education levels and class bracket of the parents than it is as a result of the formula itself. On the flip side, even these days, a dogged and unwavering determination to EBF for reasons of principle will sometimes result in a baby being underweight and failing to thrive to the point that HCPs will need to step in and monitor the situation.
And I truly believe that the recent trend for extending Bfing and weaning onto solids post 6 months or even later, and a reluctance to give a baby a bottle at all, instead going from breast to cup, is possibly a factor in many children/toddlers developing up with sensory issues over different tastes and textures and will result in more cases of very fussy eating and food related anxiety.
