Dear Friends:
There are studies, new to me, that link development of peanut allergy
with the use of soy formula. Many feel that if a mother is breastfeeding and
wants to use formula, that she should use soy-based formula. I don't why or where
that attitude came from.
Here's one of those studies:

BACKGROUND: The prevalence of peanut allergy appears to have increased in
recent decades. Other than a family history of peanut allergy and the presence of
atopy, there are no known risk factors.
RESULTS: Forty-nine children had a history of peanut allergy; peanut allergy
was confirmed by peanut challenge in 23 of 36 children tested. There was no
evidence of prenatal sensitization from the maternal diet, and peanut-specific
IgE was not detectable in the cord blood. Peanut allergy was independently
associated with intake of soy milk or soy formula (odds ratio, 2.6; 95 percent
confidence interval, 1.3 to 5.2), rash over joints and skin creases (odds ratio,
2.6; 95 percent confidence interval, 1.4 to 5.0), and oozing, crusted rash
(odds ratio, 5.2; 95 percent confidence interval, 2.7 to 10.2). Analysis of
interview data showed a significant independent relation of peanut allergy with the
use of skin preparations containing peanut oil (odds ratio, 6.8; 95 percent
confidence interval, 1.4 to 32.9).
CONCLUSIONS: Sensitization to peanut protein may occur in children through
the application of peanut oil to inflamed skin. The association with soy protein
could arise from cross-sensitization through common epitopes.
