our food, globally has changed dramatically, the last 100 yrs of advice re weaning has also changed.
formula, has been and still is a form of human experiment, its a fab invention that saves lives , but is over used, so you could ? the over use of non human protein in early diets.
For instance during the '70s a new formula for babies came out, and they had a crop of infants with kidney failure. it was only then they realised that over fed infants, got too much salt from the milk, and then they thought to remove it...
As for the growth of those with true problems with milk has risen dramatically.
Then there was the advice to avoid peanuts while pregnant and breastfeeding, which was advice for those with atopic disease in family, but everyone seem to grasp this idea, and the rate of peanut allergy in infants without parental atopic history, has risen 200% since the nhs put this advice in to place.
Hence the LEAP study, which is taking the idea of early introduction of peanut /egg halting the onset of allergy developing.
i suspect that my own grandchildren will be born, and weaned early on to egg and peanut to halt allergy development.
Its interesting that a great deal of atopic disease is inherited, however, in the mix, if its atopic mother there is a higher risk of the children inheriting, if its just the father, there is less chance, but of course with both being atopic in some form, the risk of allergies developing is high.
Asthma is by far the biggest global allergic disease, which kills in uk alone 1500 people a year.
Environmental allergies are also very high, and that is a new thing, what is causing that? is this linked to the change of farming of our food? the global warming that traps the layer of pollen/mold in the air for longer?
the double glazing, carpets keeping the rate of dustmite very high in our homes? so many changes, and so many people living longer, unhealthy lives.
its a scary really when you think about it.
