Food And Food Allergies

Allergies can cause a variety of symptoms such as inflammation, swelling, irritation, itching, hives, or anaphylactic shock.

Food allergies are immune reactions that affect millions of people in the United States. It is estimated that an average of 15 million Americans have food allergies today, and every 1 in 13 of them are children (4). A food allergy can be defined as an immune system reaction that occurs after eating specific foods (10). A food allergy occurs because the immune system mistakenly identifies a specific food or substance as something harmful. The body then triggers a release of antibodies to neutralize the allergen. This release of antibodies elicits a response in the body in the form of an allergic reaction (10).

Then, the IgE molecules are differentiated into extremely specific sub-categories. Then, the IgE’s will attach to the allergen and create an antigen-antibody complex. Then, the complex will bind to a mast cell, which provokes the mast cell to release certain chemicals such as histamine and serotonin. This causes allergic symptoms, but I will get into that section later in the paper. An allergic response might lead to anaphylactic shock, a life threatening reaction that will happen in seconds after the initial intake of the allergen.

Running noses, constant sneezing, and hives! Our immune system is constantly patrolling our body, on the lookout for infections invaders. When a harmful substance is detected, the immune system kicks into overdrive. A swarm of specialized molecules called antibodies are summoned to seek out and destroy the invader. When an unfamiliar substance is mistaken as harmful, it is called an allergen. Allergens trigger an overreaction of the immune response by unnecessarily dispatching a swarm of cells to fight-off the harmless invader. Included in this army are groups of cells called basophils and mast cells, which release a chemical called histamine. Histamine allows specialized immune cells and molecules to reach infected tissues, however they also

Responses to allergy can produce any one or a combination of several of the following symptoms: Headaches, nasal congestion, wheezing, coughing, and sneezing.

However the modern era of allergies started with the description of hay fever. In 1819, Dr. John Bostock first accurately described hay fever as a disease that affected the upper respiratory tract. Hay fever in medical terms is known as seasonal allergies. Common symptoms include sneezing, a runny or stuffed nose, red, itchy, swollen or watery eyes and itching in the nose and throat.

Have you ever asked yourself what is the main factor behind all of those irritating allergies? At some point in every person’s life they experience some type of allergy that can range from dust, animals, pollens, food, etc. Some of the symptoms that come along with those allergies can range from a painless skin rash to life-threatening reactions causing ones airway to be obstructed. Some people have suggested that if you are exposed to certain foods or bacteria’s you may develop some type of reaction later in life. Studies show that every 7 years our body’s allergies change causing us to either develop new allergies or some vanish into thin air like they were never there. We are going to get to the bottom of this issue so the real question you should be asking yourself is “Are Genetics responsible for allergies like everyone assumes or is there an underlining cause that we may just not have an answer to what causes them?” In order to prove this theory to be wrong or right research has been conducted on identical and fraternal twins. If both twins contract the same allergy then theories may be right stating that allergies are affected by genetics.

A food allergy is caused when your immune system mistakenly treats harmless proteins found in certain foods as a threat. It releases a number of chemicals, which then triggers an allergic reaction.

Pollen allergies are one of the most common allergy that someone would hear about. This allergy occurs when there are multiple antigens in the air that get breathed in and then triggers one’s immune system to overreact and cause a reaction. Symptoms of a pollen allergy include sneezing, running nose, watery eyes, cough, and wheezing. This allergy can also aggravate asthma symptoms and make one’s asthma worse. Allergies are an excessive reaction from your body’s immune system that while eliminating the allergens in the pollen or whatever antigen, overestimates the threat and creates this greater than necessary

Allergies can affect the body in many ways by having a direct effect on the target organ such as the respiratory system, gastrointestinal system or skin. Allergies also can frequently cause headaches, fatigue and irritability. Allergies are caused by the immune system confusing natural proteins for a harmful invader. Most people hear of allergies and think of common symptoms such as runny noses and sneezing. However, allergies affect the entire body and may manifest differently in each individual. Patients with allergies are at greater risk of developing new allergies, asthma, skin disorders, digestive disorders, and improper immune response to a variety of pathogens or harmless environmental. An important part of preventative care is recognizing and treating patients with allergies at the first signs.

Having an allergy is a hard thing you have to check labels, watch what you eat, make sure you don’t eat what you are allergic to just to make sure you don’t die. You do all that to not have a reaction to the food that you are allergic to. Having an allergy can happen to anyone and my aunt is one of those victims…Stephanie has an allergy to shellfish, and it didn’t happen till she was 24.

It can happen when you least expect it. It can start with an itchy mouth and within minutes, turn into a case where hospitalize is a matter of life or death. Food allergies are nothing to take likely. Worse of all, children suffering from food allergies will usually see their symptoms become worse with age. About 3 million children in the U.S. are believed to be sufferers of food allergies. A food allergy occurs when the immune system mistakenly believes that something a person ate is harmful. Some of the more common diagnoses include milk, egg, soy, wheat, peanut and shellfish. Other less typical ones are strawberries, tomatoes and chocolate. As the list of dietary restrictions grows, parents find it increasingly difficult to create balanced, tasty meals their

Most people don’t understand why they suddenly develop food allergies or why they have them at all. It’s all a matter of a person’s immune system. In some people, the immune system will think something ingested is a danger and respond accordingly. When the immune system has flagged a certain substance as a danger, it

Although allergens are typically non-harmful, these are the enemies of the allergic people. These come in various forms, a few of them are dust, dust mites, pet sheddings, and flower pollen. Lastly, the great news is that you can keep your family secure by proactively employing prevention

When a person who is allergic which reaction occurs to a particular allergen comes into touch with it, an allergic reaction happen. This begins when the allergen (for example,pet) enters the body, triggering an antibody response. The antibodies attach themselves to special cells, including cells called mast cells. When the allergen comes into contact with the antibodies, these cells respond by releasing certain substances, one of which is called histamine.
