Type of food allergy
Rice allergy is a type of foodallergy. People allergic torice react to various riceproteins after consuming rice or inhaling thesteam from cooking rice. Although some reactions might lead to severehealth problems,doctors candiagnose rice allergy with many methods, and help allergic people to avoid reactions.[citation needed]
Rice proteins are regarded as the causes of allergy in people.[1][2] People allergic to rice might experiencesneezing,runny nose,itching,asthma,stomachache,hives, sores in the mouth, oreczema after eating rice.[2][3][4][5] Besides eating rice, people with a rice allergy can have reactions breathing rice steam from cooked rice. In severe cases death may result.[6][7][8]
People who suspect they might have a rice allergy can try diet avoidance on their own. They avoid rice for two weeks; if they don’t have symptoms during the avoidance period, but have symptoms when exposed to rice, they are most likely allergic to rice.[9]
Specific riceIgE, a kind ofantibody in human blood, will rise significantly when people are allergic to rice. Ablood test shows the level of the antibody.[10]
Skin prick test, the most efficient diagnosis, shows the reactions in a short period. After being pricked in their skin with some ricemixture, allergic people will experience itching and swelling within 30 minutes.[11]
Symptoms might weaken if people receive allergy injection treatments. After receiving several treatments over a year, some formerly allergic people will have no reactions after eating rice.[12]
A new choice for rice allergic people is switching togenetically modified rice which has helped ease some allergic reactions.[2][13]
Reactions might lessen after staying away from rice long-term.[3]
Unlike other food allergies, rice allergy is relatively uncommon.[4] It has been reported worldwide but mostly inChina,Japan orKorea.[13][14] Because rice is a major food inAsia, people from Asia are exposed to higher allergy risk than people from other areas.[15]
