“…The Australian HealthNuts cohort found an SPT cutoff of 4 mm to have 95% PPV of a positive raw egg white challenge in their population‐based study . Pre‐test probabilities in these populations were however likely to be high as the Italian cohort comprised of infants with known atopic dermatitis and the HealthNuts cohort, albeit a population‐based cohort, had a very high overall prevalence of challenge‐proven egg allergy (11%) . There are currently no studies on skin prick test predictive thresholds for challenge‐proven food allergy in the Asian population, and it is unlikely that thresholds from other populations can be extrapolated to the Asian population.…”

Emerging evidence for the early introduction of allergenic foods for the prevention of food allergies, such as peanut allergy in Western populations, has led to the recent publication of guidelines in the USA and Europe recommending early peanut introduction for high-risk infants with severe eczema or egg allergy. Peanut allergy is, however, much less prevalent in Asia compared to the West. Varying patterns of food allergy are seen even within Asian countries-such as a predominance of wheat allergy in Japan and Thailand and shellfish allergy in Singapore and the Philippines. Customs and traditions, such as diet and infant feeding practices, also differ between Asian populations.Hence, there are unique challenges in adapting guidelines on early allergenic food introduction to the Asian setting. In this paper, we review the evidence and discuss the possible approaches to guide the timely introduction of allergenic food in high-risk infants in Asia.

“…The prevalence of early childhood food allergy in Australia is among the highest in the world . To reduce the incidence of food allergies, the Australasian Society of Clinical Immunology and Allergy (ASCIA) recently revised their guidelines for infant feeding and allergy prevention, recommending that common food allergens, including peanut and egg, be introduced during the first year of life .…”

Objectives To estimate the proportion of infants introduced to peanut and other common food allergens by 12 months of age; to collect information about parent‐reported reactions to food. Design, setting Observational cohort study, applying the SmartStartAllergy SMS protocol and online questionnaire to parents of 12‐month‐old infants attending 69 Australian general practices between 21 September 2018 and 3 May 2019. Participants 3374 parents recruited via the 69 participating general practices. Main outcome measures Proportions of infants who had eaten peanut and other common food allergens; proportions with parent‐reported reactions to food. Results 1940 of 3374 invited parents participated in the study (response rate, 57%), of whom 836 (46%) completed the online questionnaire. At 12 months of age, 1673 of 1940 infants had eaten peanut‐including foods (86.2%; 95% confidence interval [CI], 84.6–87.7%); 235 of 1831 parents (12.8%; 95% CI, 11.3–14.5%) reported food‐related reactions. Questionnaire responses indicated that dairy was the food type most frequently reported to cause a food‐related reaction (72 of 835 exposed infants, 8.6%; 95% CI, 6.8–11%); peanut‐related reactions were reported for 20 of 764 exposed children (2.6%; 95% CI, 1.6–4.0%). 97 of 250 parent‐reported reactions to food (39%) did not include symptoms that suggested an IgE‐mediated allergic reaction. Conclusion Infant feeding practices in Australia have changed over the past decade; a large majority of infants are now fed peanut before 12 months of age. The SmartStartAllergy program allows monitoring of infant feeding practices in primary care, as well as of parent‐reported reactions to food in infants.

This article updates the latest guidance and research on the suitability of eggs as a good source of nutrition for particular population groups. This follows the publication of two important UK government reports: revised advice for vulnerable groups from the Food Standards Agency and a draft report about infant feeding from the Scientific Advisory Committee on Nutrition (SACN), as well as a recent review on egg consumption and cardiovascular disease risk in people with type 2 diabetes. The Food Standards Agency now advises that raw or lightly cooked British eggs are safe to eat for vulnerable groups, such as pregnant women, babies, toddlers and older people, provided that the eggs bear the Lion mark. This indicates that they have been produced under the British Lion Code of Practice, a scheme that includes more than 700 auditable criteria, of which vaccination of laying hens against Salmonella is a key aspect. The draft SACN report Feeding in the First Year of Life recommends that first complementary foods should be introduced from around 6 months of age and that there is no need to differentiate hens' egg from other foods in this respect. There is also a warning that the deliberate exclusion or delayed introduction of allergenic foods including egg may increase the risk of allergy to these foods later in childhood. As regards people with type 2 diabetes, despite earlier concerns from epidemiological studies that higher egg intake might increase cardiovascular disease risk, more recent high-quality intervention studies indicate that, provided eggs are consumed as part of a healthy, energy-controlled diet, there is no need for concern. Eggs provide a wide range of important nutrients, including several that are found in only a limited number of other foods, such as vitamin D, iodine and the long-chain omega-3 fatty acid, docosahexaenoic acid. They are therefore a useful and versatile ingredient for pregnant women, infants and children, and older people.

The prevalence of food allergy and other allergic diseases in early childhood in a population-based study: HealthNuts age 4-year follow-up

Abstract: Although the prevalence of food allergy decreased between age 1 year and age 4 years in this population-based cohort, the prevalence of any allergic disease among 4-year-old children in Melbourne, Australia, is remarkably high.
