According to a report in the Ta Kung Pao on August 13, a new study on food allergies has found that milk, eggs, and gluten are the top three most common delayed food allergens, followed by soybeans and kidney beans. The survey also revealed that more people are allergic to gluten and soybeans. Skin rashes are the most common allergic symptom, followed by eczema, nasal sensitivity, fatigue, bloating, headaches, and constipation.
"The public generally considers milk and eggs to be highly nutritious foods, and that eating more of them will increase nutrition, but they don't know that excessive consumption can lead to allergies," said Dr. Leung Sau-fong, a Hong Kong pediatrician. Food allergic reactions are of two types: immediate and delayed. The survey organization warns: "The latter is more difficult to prevent, and delayed allergic reactions to eggs are especially unpredictable."
The 147 doctors who participated in the survey suggested that for treating food allergies, one should avoid consuming the allergenic foods, find substitutes for them, use medication, and take some health supplements.
