General Information

America's Top Allergy Capitals “Louisville, Ky., is the most challenging place to live for people with spring allergies, according to the Asthma and Allergy Foundation of America's 2009 list of top 100 Spring Allergy Capitals. The list, released Wednesday, is based on the impact that key environmental and medical factors have on people with allergies. The rankings are published annually to help allergy sufferers recognize, prevent and treat symptoms. Other cities in the top 10 are: Knoxville, Tenn.; Charlotte, N.C.; Madison, Wis.; Wichita, Kan.; McAllen, Texas; Greensboro, N.C.; Dayton, Ohio; Little Rock, Ark.; and Augusta, Ga.”

Food, Cosmetic Labels to Note Dye Derived From Bug “Foods and cosmetics containing the color additives carmine and cochineal extract, which are made from an insect, must list those ingredients on their labels starting on Jan. 5, 2011. The FDA published that new rule in yesterday's edition of the Federal Register, citing reports of "severe allergic reactions, including anaphylaxis" in a "small subset" of people with allergies.”

Fresh fruit allergies on the rise “It used to be an apple a day kept the doctor away but it seems the reverse can sometimes happen. Immunologists in the UK say fruit and vegetables are replacing the peanut as a major cause of allergies in children. Doctors in Australia agree that more and more people are reacting to fresh produce, particularly bananas.”

'Hygiene Hypothesis' Challenged: Day Care Doubles Early Respiratory Problems, Does Not Prevent Later Asthma And Allergy

Low Folate May Be Linked to Allergies “But she warns that it is too soon to recommend that people take folic acid -- the synthetic form of folate used in supplements -- in an effort to reduce their risk for allergy and asthma or to treat symptoms. "That would be premature," she says. "Our findings are a clear indication that folic acid may indeed help regulate immune response to allergens, and may reduce allergy and asthma symptoms. But we still need to figure out the exact mechanism behind it, and to do so we need studies to follow people receiving treatment with folic acid." Few Are Folate Deficient Less than 5% of Americans have so little folate in their blood that they are considered deficient in the B vitamin, Matsui says. That's because since 1996, the U.S. government has required folic acid to be added to cereals, flours, pastas, rice, and other grain products in an effort to ensure that pregnant women get enough of the vitamin to protect against certain birth defects. Folate is also abundant in leafy green vegetables like spinach and turnip greens, citrus fruits, dried beans, liver, and many other foods.”

Allergies and asthma: They often occur together

Try This Laundry Trick for Allergy Relief “You may be able to turn your allergy symptoms down a notch by turning up the heat. Yep, set your washer temp on "hot." And the rinse cycle on "extra." Studies show these settings remove way more symptom-provoking dust mites, dog dander, and tree pollen from laundry than cold-water, single-rinse cycles.”

JOURNAL ARTICLES:

Air Pollution and Childhood Respiratory Allergies in the United States. (Environ Health Perspect. 2009) “CONCLUSIONS: These results provide evidence of adverse health for children living in areas with chronic exposure to higher levels of O(3) and PM(2.5) compared with children with lower exposures.”

Household peanut consumption as a risk factor for the development of peanut allergy. (J Allergy Clin Immunol. 2009) “CONCLUSIONS: High levels of environmental exposure to peanut during infancy appear to promote sensitization, whereas low levels may be protective in atopic children. No effect of maternal peanut consumption during pregnancy or lactation is observed, supporting the hypothesis that peanut sensitization occurs as a result of environmental exposure.”

The association between early sensitization patterns and subsequent allergic disease. The DARC birth cohort study. (Pediatr Allergy Immunol. 2009) “Children with atopic dermatitis, asthma, or rhinoconjunctivitis, and sensitization at 6 yr, were sensitized to food allergens to a large extent (53%, 42%, and 47%, respectively) already at 6 months. Early inhalant sensitization (S-IgE) did not increase the risk of later allergic disease. Early atopic dermatitis (0-18 months) was also highly associated with subsequent allergic disease.”

The low prevalence of allergic disease in Eastern Europe. (Clin Exp Allergy. 2009) “Results Significantly increased risks of wheezing and hayfever symptoms in the past 12 months, and of recurrent itchy rash were observed in boys, children with a positive first-degree family atopic history, and those who had received probiotics (especially as prophylaxis with antibiotic use). Pet ownership, contact with farm animals, the presence and number of younger and (especially) older siblings, and residency in rural areas of Western Belarus were associated with reduced risks. Maternal postnatal smoking was associated with wheezing and hayfever symptoms, while the duration of exclusive breastfeeding was not protective against any of the studied outcomes. The risk factors for allergic symptoms were similar in children with positive skin-prick tests to those in the overall cohort. Conclusion Many of the risk and protective factors we identified are consistent with those reported in Western countries and with the hygiene hypothesis. Further research on dietary and other environmental and genetic factors is necessary to understand the low prevalence of allergic disease in Belarus and other Eastern European countries.”
