Rice allergy

Last updated

Rice allergy is a type of food allergy. People allergic to rice react to various rice proteins after consuming rice or inhale the steam from cooking rice. Although some reactions might lead to severe health problems, doctors can diagnose rice allergy with many methods and help allergic people to avoid reactions.[ citation needed ]

Symptoms and signs

Some rice proteins are regarded as the causes of allergy in people. [1] [2] People allergic to rice might experience sneezing, runny nose, itching, asthma, stomachache, hives, sores in the mouth, or eczema after they eat 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]

Diagnosis

People suspected of having a rice allergy can try diet avoidance on their own. First, they have to avoid rice for a couple of weeks. If they don’t have symptoms in the avoidance period but have those when exposed to rice, they are most likely allergic to rice. [9]

Specific rice IgE, a kind of antibody in human blood, will rise significantly when people are allergic to rice. A blood 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 rice mixture, allergic people will get itching and swelling in about 30 minutes. [11]

Treatment

Some symptoms might weaken if people get allergy shots. After getting several treatments for a long time, some allergic people will not have reactions afterwards. [12]

Some reactions have been eased by replacing original rice with genetically modified rice. This is regarded as a new choice for rice allergic people. [2] [13]

Reactions might lessen by staying away from rice long-term. [3]

Prevalence

Unlike other food allergies, rice allergy is relatively uncommon. [4] It has been reported worldwide but mostly in China, Japan or Korea. [13] [14] Because rice is a major food in Asia, people from Asia are exposed to higher allergy risk than people from other areas. [15]

Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, coughing, a runny nose, shortness of breath, or swelling. Note that food intolerances and food poisoning are separate conditions.

An allergen is a type of antigen that produces an abnormally vigorous immune response in which the immune system fights off a perceived threat that would otherwise be harmless to the body. Such reactions are called allergies.

<span class="mw-page-title-main">Allergic rhinitis</span> Nasal inflammation due to allergens in the air

Allergic rhinitis, of which the seasonal type is called hay fever, is a type of inflammation in the nose that occurs when the immune system overreacts to allergens in the air. Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. The fluid from the nose is usually clear. Symptom onset is often within minutes following allergen exposure, and can affect sleep and the ability to work or study. Some people may develop symptoms only during specific times of the year, often as a result of pollen exposure. Many people with allergic rhinitis also have asthma, allergic conjunctivitis, or atopic dermatitis.

A radioallergosorbent test (RAST) is a blood test using radioimmunoassay test to detect specific IgE antibodies in order to determine the substances a subject is allergic to. This is different from a skin allergy test, which determines allergy by the reaction of a person's skin to different substances.

<span class="mw-page-title-main">Food allergy</span> Hypersensitivity reaction to a food

A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure. This typically occurs within minutes to several hours of exposure. When the symptoms are severe, it is known as anaphylaxis. A food intolerance and food poisoning are separate conditions, not due to an immune response.

<span class="mw-page-title-main">Allergen immunotherapy</span> Medical treatment for environmental allergies

Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies, such as insect bites, and asthma. Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.

<span class="mw-page-title-main">Peanut allergy</span> Type of food allergy caused by peanuts

Peanut allergy is a type of food allergy to peanuts. It is different from tree nut allergies, because peanuts are legumes and not true nuts. Physical symptoms of allergic reaction can include itchiness, hives, swelling, eczema, sneezing, asthma attack, abdominal pain, drop in blood pressure, diarrhea, and cardiac arrest. Anaphylaxis may occur. Those with a history of asthma are more likely to be severely affected.

<span class="mw-page-title-main">Soy allergy</span> Type of food allergy caused by soy

Soy allergy is a type of food allergy. It is a hypersensitivity to ingesting compounds in soy, causing an overreaction of the immune system, typically with physical symptoms, such as gastrointestinal discomfort, respiratory distress, or a skin reaction. Soy is among the eight most common foods inducing allergic reactions in children and adults. It has a prevalence of about 0.3% in the general population.

Oral allergy syndrome (OAS) or pollen-food allergy is a type of food allergy classified by a cluster of allergic reactions in the mouth and throat in response to eating certain fruits, nuts, and vegetables. It typically develops in adults with hay fever.

Nambudripad's Allergy Elimination Techniques (NAET) is a form of alternative medicine which proponents claim can treat allergies and related disorders. The techniques were devised by Devi Nambudripad, a California-based chiropractor and acupuncturist, in 1983, drawing on a combination of ideas from applied kinesiology, acupuncture, acupressure, nutritional management, and chiropractic methods.

<span class="mw-page-title-main">Milk allergy</span> Type of food allergy caused by milk

Milk allergy is an adverse immune reaction to one or more proteins in cow's milk. Symptoms may take hours to days to manifest, with symptoms including atopic dermatitis, inflammation of the esophagus, enteropathy involving the small intestine and proctocolitis involving the rectum and colon. However, rapid anaphylaxis is possible, a potentially life-threatening condition that requires treatment with epinephrine, among other measures.

Skin allergy testing comprises a range of methods for medical diagnosis of allergies that attempts to provoke a small, controlled, allergic response.

Allergy testing can help confirm or rule out allergies and consequently reduce adverse reactions and limit unnecessary avoidance and medications.

<span class="mw-page-title-main">Allergies in children</span> Medical condition

Allergies in children, an incidence which has increased over the last fifty years, are overreactions of the immune system often caused by foreign substances or genetics that may present themselves in different ways. There are multiple forms of testing, prevention, management, and treatment available if an allergy is present in a child. In some cases, it is possible for children to outgrow their allergies.

<span class="mw-page-title-main">Sesame allergy</span> Food allergy caused by sesame seeds

A food allergy to sesame seeds has prevalence estimates in the range of 0.1–0.2% of the general population, and are higher in the Middle East and other countries where sesame seeds are used in traditional foods. Reporting of sesame seed allergy has increased in the 21st century, either due to a true increase from exposure to more sesame foods or due to an increase in awareness. Increasing sesame allergy rates have induced more countries to regulate food labels to identify sesame ingredients in products and the potential for allergy. In the United States, sesame became the ninth food allergen with mandatory labeling, effective 1 January 2023.
