Objective To systematically review and meta - analyze evidence that
timing of allergenic food introduction during infancy influences risk of allergic or autoimmune disease.
Peanut allergy develops early in life and is rarely outgrown.7 - 9 Clinical practice guidelines from the United Kingdom in 19989 and from the United States in 200010 recommended the
exclusion of allergenic foods from the diets of infants at high risk for allergy and from the diets of their mothers during pregnancy and lactation.
It is reported to detect allergenic peptides from five of the major
classes of allergenic foods at a detection limit of 10 ppm in a variety of food matrices.
For those with severe food allergies, eating even the slightest
trace of an allergenic food can cause a potentially life threatening or fatal reaction.
If your baby has tried and done well with a few of these, start giving her
tastes of allergenic foods such as peanut products and eggs.
To systematically review and meta - analyze evidence that
timing of allergenic food introduction during infancy influences risk of allergic or autoimmune disease.
In fact, there is growing evidence that early
introduction of allergenic foods has a protective effect against food allergies and that delaying the introduction of them could increase the risk of food allergies (beyond 10 months for eggs was the only specific age I could find).
Timing
of allergenic food introduction to the infant diet and risk of allergic or autoimmune disease: a systematic review and meta - analysis.
In fact, delaying the introduction
of allergenic foods may actually raise the risk of food allergies.

of allergenic food introduction to the infant diet and risk of allergic or autoimmune disease: A systematic review and meta - analysis.
Early introduction
of allergenic foods may prevent food allergy in children.
First, let me quash the widely held notion that delaying the introduction
of allergenic foods to babies is a good idea.
Old Rule Avoid giving your child eggs, wheat, nut butter, and dairy until after age 1 New Rule Offer these allergenic foods carefully at 6 months With some food allergies almost doubling between 1997 and 2011, pediatricians thought that delaying the introduction
of allergenic foods would help keep these numbers down.
«The clinical implications of our findings are that early introduction
of allergenic foods (egg, cow's milk products, and peanut) before age one should be encouraged and is better than food avoidance for reducing the risk of food sensitization,» said Mr. Tran.
Dr Louisa James, British Society for Immunology spokesperson, says considering the increased prevalence of food allergies over recent decades, new guidelines on the timing of introduction
of allergenic food to the infant diet are warranted.
«It is not clear that it is the specific early introduction
of an allergenic food that renders immunological protection, rather than the accompanying increased diversity in the diet that occurs as a by - product,» writes Dr. Matthew Greenhawt, an allergy and immunology specialist at Children's Hospital Colorado, in the accompanying editorial.
Question Does the timing
of allergenic food introduction to infants affect their risk of developing allergic or autoimmune disease?
