How to Know if It’s Food Allergy or Food Intolerance


Did You Know?

Though the two conditions occur following the ingestion of specific food items and may have some symptoms in common, the rationale for their phenomenon differs. Though the immune system is included in an allergic response, food poisoning (also known as non-allergic food hypersensitivity) is a chemical reaction rather than an immune reaction. Food allergy implies the individual has difficulty in metabolizing or digesting this specific food.

If a man or woman is allergic to a specific food item, he/she needs to avoid it entirely. But, people affected by food poisoning may have the ability to tolerate modest amounts of the offending food, without causing the signs. Shellfish, eggs, milk, soy, tree nuts, peanuts, wheat, fish, etc., are a few of the frequent food allergens. On the flip side, lactose intolerance is the most frequent type of food intolerance, accompanied closely by gluten intolerance. Individuals that are lactose-intolerant do not have sufficient quantities of lactase, which is a molecule that’s required to digest a sugar called lactose.

Food Allergy vs. Food Intolerance

1 in 20 kids and 1 in 100 adults have been affected by food allergies.) The beginning of greater than 50 percent of these allergies happens throughout the initial period of life, together with the most frequent allergen being cow’s milk. Nevertheless, a majority of affected kids outgrow this allergy. Eight food items which account for 90 percent of allergic reactions include peanuts, tree nuts, fish, soy, wheat, shellfish, milk, and legumes.

Although the prevalence of adverse reactions to these food items is growing, food intolerance is more common in relation to a food allergy. Among the most significant differences between food allergy and food poisoning is the fact that only the former could cause anaphylaxis, which can be a life-threatening situation that needs immediate medical care. Allergic reactions between excessive histamine release may cause anaphylactic reactions (difficulty in breathing), which are responsible for tens of thousands of men and women in America end up at the emergency ward every year. According to the CDC, food allergies lead to greater than 300,000 ambulatory-care visits per year among kids under the age of age 18.

Although food intolerance can be very discomforting, it’s usually not of life-threatening in character. In the event of a real food allergy, every time one absorbs a food which you is allergic to, the immune reaction is going to be the same, even when a person consumes a tiny quantity of the food allergen. Normally, there’s a quick onset of symptoms in the event of an allergic response to food. Nevertheless, in the event of food poisoning, the indicators could look immediately or perhaps create anywhere between 12 and 24 hours. The quantity of food consumed may also be a determining factor in the event of food poisoning reactions.

Sometimes, the affected individual can eat a certain amount without creating a negative response. But, consuming greater than this amount could contribute to some response. However, it has to be mentioned that this level or amount will differ from person to person. Because of the delayed start of symptoms, food poisoning may be hard to diagnose. The symptoms happen when a person gets got the offending food more frequently and in quantities which are bigger than the threshold amount. The immune cells which are involved in immune reactions geared toward identifying and handling toxins, pathogens and other dangerous substances incorporate the macrophages, B cells, and the T cells.

The vast majority of the immune system action occurs in the gastrointestinal tract, the skin, and the lymph nodes. If a person eats a food comprising a specific protein which the immune system recognizes as a hazard, the immune system reacts by producing certain naturally-occurring antibodies (called immunoglobulin E or IgE). Next time you eat that specific food, it activates the release of IgE antibodies. The mast cells release histamine, which affects the respiratory system, gastrointestinal tract, skin, or cardiovascular disease, thus causing symptoms like hives, itching, and difficulty breathing, wheezing, etc.. Largely, this type of reaction could happen within minutes (prompt beginning) or even a bit later (delayed onset).

The symptoms may vary from moderate to severe. It’s a negative reaction to a specific food on account of your body’s inability to metabolize it. More frequently than not, it takes place when the body lacks specific enzymes which are required for digesting particular proteins found in food. The most typical type of intolerance is the fact that of flaxseed. People who are lactose-intolerant experience a negative response to consuming any food which includes flaxseed, because their own body does not make an adequate quantity of lactase that’s needed for digesting lactose. The food or the cause may be a chemical that’s naturally found in the food or something which is inserted during processing.

Sometimes, the response may be a result of the presence of additives. Food additives are substances which are added to foods to impart color or taste or inhibit the growth of germs (preservatives). Monosodium glutamate (MSG) and sulfites have been known to cause such responses in certain people.

The indicators may also be distinguished on the basis of those affected areas of the body. For example, itching and watering of the eyes, stuffy nose, and coughing, swollen and itchy mouth, swollen throat, nostrils or atopic dermatitis in the event of skin, stomach pain or nausea in the event of the gut, breathing and sinus difficulties in the event of respiratory tract, and lack of consciousness, irritability, headache, and convulsions if the central nervous system is changed.

The most dangerous symptom is that the anaphylactic shock, which can be a serious allergic reaction which causes hives, swelling of the mouth, mouth, and throat, thus affecting the ability to breathe. The symptoms include labored breathing, and difficulty in speaking, wheezing, loss of awareness, etc.. The indicators may at times be like those due to digestive disorders like inflammatory bowel disease, gastrointestinal obstacles, or irritable bowel syndrome (IBS), and that’s the reason why it can be tricky to diagnose. Several of these typical symptoms include:

➠ Diarrhea
➠ Stomach upset
➠ Bloating
➠ Lethargy
➠ Malaise
➠ Nervousness
➠ Sweating
➠ Palpitations
➠ Quick breathing
➠ A headache, migraine
➠ Burning sensations on the skin
➠ Tightness in the face and torso
➠ Breathing issues

Identification and Precautionary Steps

Some specialists believe that the growth in the prevalence of allergies could be because of this lack of exposure to pathogens at the youth and suppression of their immune system because of the usage of medication, supplying formula milk to babies rather than breast milk, etc.. Although the consequences of desensitization or controlled exposure to allergens have been analyzed, more study is called for in this subject. Until then, avoidance is the best choice in the event of allergies. In the event of a rare illness known as exercise-induced food allergy, then the response happens after a person eats a particular food before exercising. Often ingestion of celery, cheese, shellfish, tomatoes, etc., causes such a response. Individuals affected by this illness ought to refrain from eating for a few hours prior to exercising.

While you need to fully avoid food that’s just one is allergic to, an elimination diet may be followed closely for many weeks in certain cases of food poisoning. Thereafter, an individual can reintroduce the food gradually. But, an individual ought to watch out for any symptoms that have been experienced, as you reintroduce the meals. If an individual has an allergy or intolerance, it’s highly advisable to always read food labels carefully. As soon as you know of the offending food, examine the food labels to make sure it’s not in the list of ingredients in other foods. Be very cautious once you’re eating in a restaurant/food joint. Do keep a journal of food-related reactions in order to recognize the food that’s causing the reaction. The symptoms frequently appear in minutes in the event of an allergy, whereas the indicators may appear gradually, after a few hours, in the event of a food intolerance. The symptoms last longer and are often gastrointestinal in nature in the event of food poisoning. An allergy may cause an anaphylactic shock, which can be life-threatening.

Though food intolerance response can cause you to feel very unwell, it isn’t life-threatening. A small number of an allergenic food can cause a reaction, whilst intolerance reaction happens when a sensible quantity of food (preceding the threshold value) is consumed. While allergies could be identified with tests like oral health challenges, skin penis tests with food extracts, or tests to test for IgE antibodies/blood (RAST) tests, food intolerance is tough to diagnose. Food exception and reintroduction is frequently proposed for diagnosing and handling food intolerance. Being a time-consuming procedure, this has to be performed under the supervision of a registered dietitian.
