The Law of Food Allergy and Accommodation in Canadian Schools
A recent article examined how current laws in Canada can guide future school policies to accommodate allergies, food bans and disabilities in children. See additional resources from the School Health Knowledge Pathway Related Tools and Resources along with these country-specific guidelines:
Food Sensitivity Tests
A recent article was published by CBC Marketplace about the misuse and misinterpretations of IgG tests for food intolerance. The article notes that medical experts, including the Canadian Society of Allergy and Clinical Immunology (CSACI), call IgG tests for food sensitivities “unvalidated,” and more than two dozen organizations warn about the misuse of such tests. Related information will be updated in the Food Allergies Knowledge Pathway soon.
Introduction of Allergenic Food to Infants, Especially Peanuts: Interim Guidelines for Canadian Dietitians
This interim DC communication provides DC members with information on the scientific evidence regarding the introduction of peanuts to infants and how the current dietetic practice recommendations agree and differ from NIAID recommendations published in January 2017. In brief, the key differences between these new NIAID guidelines and current Canadian Nutrition for Healthy Term Infant (NHTI) recommendations are in the different definitions of “at risk” infants, the strength of wording for introducing peanut containing food early, and the recommendation to undergo physician supervised testing/feeding before introduction for a small subset of very high-risk infants . Refer to the full document for more information. See also the PEN Evidence Clip : Food Allergy Prevention in Infants.

Continued Support for Early Introduction of Peanuts
In a follow up of an earlier study (see PEN® Article Analysis: Peanut Consumption in Infants at Risk for Peanut Allergy), researchers have found continued support that the early introduction of peanuts reduces the prevalence of peanut allergy in children at high risk. At the end of the primary study, researchers withheld peanut for a year following a five-year exposure. They found that even after a full year of not eating peanut, upon reintroduction there was no significant increase in prevalence of peanut allergy; the prevalence of peanut allergy was still about 74% lower than the prevalence in the group who avoided peanuts throughout the 6 years. The full article, The Effect of Avoidance on Peanut Allergy after Early Peanut Consumption is available at NEJM.
