The lower the vitamin D level, the more allergies each child had
OBJECTIVE: To investigate the association between serum vitamin D levels, sensitization to food allergens, and the severity of atopic dermatitis in infants.
STUDY DESIGN: We investigated serum 25-hydroxyvitamin D (25[OH]D) and specific immunoglobulin E levels to common or suspected food allergens in 226 infants with atopic dermatitis or food allergy. The severity of atopic dermatitis by the Scoring Atopic Dermatitis index and amount of vitamin D intake was measured in subcohort children. Sensitization to food allergen was categorized by the number (non-, mono-, and poly-) of sensitized allergens and the degree (undetected-, low-, and high-level) of sensitization.
RESULTS: Significant differences in 25(OH)D levels were found between groups on number (P = .006) and degree (P = .005) of food sensitization. The polysensitization group had significantly lower levels of 25(OH)D than the nonsensitization (P = .001) and monosensitization (P = .023) group. High-level sensitization group had significantly lower 25(OH)D levels compared with undetected (P = .005) and low-level (P = .009) sensitization group. Vitamin D deficiency increased the risk of
- sensitization to food allergens (OR 5.0; 95% CI 1.8-14.1), especially to
- milk (OR 10.4; 95% CI 3.3-32.7) and
- wheat (OR 4.2; 95% CI 1.1-15.8).
In addition, the Scoring Atopic Dermatitis index was independently related to 25(OH)D levels after adjusting for the level of sensitization (adjusted R(2) = 0.112, P = .031).
CONCLUSIONS: Our results suggest that vitamin D deficiency increases the risk of sensitization to food allergens and that atopic dermatitis may be more severe in infants with vitamin D deficiency.

10X more likely to have multiple food allergies if low vitamin D - Sept 2013
Vitamin D levels and food and environmental allergies in the United States - May 2011
Results from the National Health and Nutrition Examination Survey 2005-2006
The Journal of Allergy and Clinical Immunology, Volume 127, Issue 5 , Pages 1195-1202, May 2011

Background: Previous research supports a possible link between low vitamin D levels and atopic disease.
However, the association between low vitamin D levels and total and allergen-specific IgE levels has not been studied.
Objective: We sought to test the association between serum 25-hydroxyvitamin D (25[OH]D) deficiency (<15 ng/mL) and insufficiency (15-29 ng/mL) and allergic sensitization measured by serum IgE levels in a US nationally representative sample of 3136 children and adolescents and 3454 adults in the National Health and Nutrition Examination Survey 2005-2006.
Methods: The association of 25(OH)D deficiency with 17 different allergens was assessed after adjustment for potential confounders, including age; sex; race/ethnicity; obesity, low socioeconomic status; frequency of milk intake; daily hours spent watching television, playing videogames, or using a computer; serum cotinine levels; and vitamin D supplement use.
Results: In children and adolescents allergic sensitization to 11 of 17 allergens was more common in those with 25(OH)D deficiency. Compared with sufficient vitamin D levels of greater than 30 ng/mL, after multivariate adjustment, 25(OH)D levels of less than 15 ng/mL were associated with
- peanut (odds ratio [OR], 2.39; 95% CI, 1.29-4.45),
- ragweed (OR, 1.83; 95% CI, 1.20-2.80), and
- oak (OR, 4.75; 95% CI, 1.53-4.94) allergies (P < .01 for all).
Eight other allergens were associated with 25(OH)D deficiency, with P values of less than .05 but greater than .01.
There were no consistent associations seen between 25(OH)D levels and allergic sensitization in adults.
Conclusion: Vitamin D deficiency is associated with higher levels of IgE sensitization in children and adolescents.
Further research is needed to confirm these findings.

Current evidence supports a role for gut colonization in promoting and maintaining a balanced immune response in early life. An altered or less diverse gut microbiota composition has been associated with atopic diseases, obesity, or both. Moreover, certain gut microbial strains have been shown to inhibit or attenuate immune responses associated with chronic inflammation in experimental models. However, there has been no fully adequate longitudinal study of the relation between the neonatal gut microbiota and the development of allergic diseases (eg, atopic asthma) and obesity. The emergence of promising experimental studies has led to several clinical trials of probiotics (live bacteria given orally that allow for intestinal colonization) in human subjects. Probiotic trials thus far have failed to show a consistent preventive or therapeutic effect on asthma or obesity. Previous trials of probiotics have been limited by small sample size, short duration of follow-up, or lack of state-of-the art analyses of the gut microbiota. Finally, there is emerging evidence that the vitamin D pathway might be important in gut homeostasis and in signaling between the microbiota and the host. Given the complexity of the gut micriobiota, additional research is needed before we can confidently establish whether its manipulation in early life can prevent or treat asthma, obesity, or both.

Objective 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.
