On the other hand, Ms. Yolanda Che from the local organic industry notes that low-allergen foods is getting more and more popular both globally and locally, reflecting the increase in the number of food allergy and sensitivity sufferers in the society. With the high popularity of avoiding food allergens to soothe chronic symptoms in Europe and USA, manufacturers actively develop new low-allergen products, making these products to have similar tastes and textures as the ordinary foods.
