Purpose of the ReviewWhilst food allergy seems to have increased significantly in many developed countries in the past few decades, quality data on the burden of food allergy in many developing countries is scanty. Until recently, South Africa had a dearth of robustly designed food allergy studies. This article summarizes some of the recent research and observations regarding food allergy from the South African setting.Recent FindingsSouth Africa has recently seen two important food allergy… 

Mapping Allergic Diseases in Sub-Saharan Africa

TLDR
Allergic disease mapping is crucial to grasp the full extent of Africa's allergic diseases' impact, and will require diverting resources to diagnose and study allergies, even more at the dawn of precision medicine.

Potential of Egg as Complementary Food to Improve Nutrient Intake and Dietary Diversity

TLDR
It was showed that frequent egg consumption can contribute safely to complementary food for babies, especially in low- and middle-income countries.

A selective and sensitive nanosensor for fluorescent detection of specific IgEs to purified allergens in human serum

TLDR
The application of EMFP to immunoassays indicated a detection limit of 0.0159 ng mL−1 for low concentration specific immunoglobulin E (sIgE) against purified shellfish Metapenaeus ensis (Meta. E.) allergens, which is 15 fold more sensitive than the commercially available Food and Drug Administration-approved analyzers.

Food allergy in South Africa : joining the food allergy epidemic? : review articles

TLDR
A recent food allergy prevalence study in eczematous patients in Cape Town has shown a surprisingly high rate of challenge-proven food allergies in children of both Xhosa and mixed descent, suggesting that South Africa may not be spared from the food allergy epidemic.

Food Allergy: International and Developing World Perspectives

TLDR
The little data on food allergy from rural and developing world settings suggest that the prevalence may be lower but challenges experienced by patients may be higher than that in the urban developed world.

A global survey of changing patterns of food allergy burden in children

TLDR
There remains a need to gather more accurate data on the prevalence of food allergy in many developed and developing countries to better anticipate and address the rising community and health service burden of food allergies.

Which test is best for diagnosing peanut allergy in South African children with atopic dermatitis?

TLDR
The component Ara h 2 was useful for differentiating allergy from tolerance in both ethnic groups in this SA cohort, and ninety-five percent PPVs for peanut allergy tests may need to be revised, especially in Xhosa patients.

PATTERNS OF INTRODUCTION OF SOLIDS IN SOUTH AFRICAN CHILDREN WITH ATOPIC DERMATITIS: DO THEY AFFECT ALLERGY RATES?

TLDR
This research formed part of a study investigating the prevalence of IgE-mediated food allergy in 100 South African children with atopic dermatitis, where food allergy was determined by a combination of history, sensitisation patterns, and open incremental oral food challenges.

[Prevalence of food allergy in Icelandic infants during first year of life].

TLDR
The results show lower prevalence of food allergy than previously reported in a study of Icelandic children at two years of age and could be explained by different genetic and environmental factors.

Utility of food-specific IgE concentrations in predicting symptomatic food allergy.

TLDR
Quantification of food-specific IgE is a useful test for diagnosing symptomatic allergy to egg, milk, peanut, and fish in the pediatric population and could eliminate the need to perform double-blind, placebo-controlled food challenges in a significant number of children.
