BPA exposure by infants may increase later risk of food intolerance

If it seems like more people are allergic to, or intolerant of, more and
different kinds of foods than ever before, there might be a reason why.
A new research published in November 2014 issue of The FASEB Journal,
scientists show, for the first time, that there is a link between
perinatal exposure to Bisphenol A (BPA) at low doses and the risk to
develop food intolerance in later life. This research involving rats
suggests that early life exposure at a dose significantly below the
current human safety limit set by the FDA affects developing immune
systems, predisposing offspring to food intolerance in adulthood.

Geographic Variability of Childhood Food Allergy in the United States

The aim of this study was to describe the distribution of childhood food allergy in the United States. Methods. A randomized survey was administered electronically from June 2009 to February 2010 to adults in US households with at least 1 child younger than 18 years. Data were analyzed as weighted proportions to estimate prevalence and severity of food allergy by geographic location. Multiple logistic regression models were constructed to estimate the association between geographic location and food allergy. Results. Data were analyzed for 38 465 children. Increasing population density corresponded with increasing prevalence, from 6.2% in rural areas (95% confidence interval [CI] = 5.6-6.8) to 9.8% in urban centers (95% CI = 8.6-11.0). Odds of food allergy were graded, with odds in urban versus rural areas highest (odds ratio [OR] = 1.7, 95% CI = 1.5-2.0), followed by metropolitan versus rural areas (OR = 1.4, 95% CI = 1.2-1.5), and so on. Significance remained after adjusting for race/ethnicity, gender, age, household income, and latitude. Conclusions. An association between urban/rural status and food allergy prevalence was observed.
