Recommended: What is the study and function of the immune system
Healthy humans have two types of immune systems that protect the body from invading pathogens that cause diseases. The Innate Immunity is the first barrier of protection. It is similar to a force field. Its primary purpose is to destroy any pathogen that tries to enter the epidermis cells (the skin cells) and the mucosa (mucus secreting cells found in the GI tract, respiratory tract, urogenital tract and eyes. If the first defense does not work, the adaptive immunity steps in to eradicate the invading microbe. Yet, sometimes the body reacts to harmless agents as if they were pathogens. Every day, more adults develop allergies to things in their environment. Exposure to such things as pollen, grass, mold and pet dander1 can lead to mild or harmful reactions. Other allergens can cause tingling in the throat and mouth, and in many cases severe reaction that lead to death. 2 In the last couple of decades, 75 to 100 percent of asthma and 150 percent atopy have reported.4 17.7 million adults and 7.1 million were diagnosed with allergies and hay fever.5 There are no known reasons why people developed hypersensitivity to certain agents, yet, many adults are developing allergies later in life. Statistically, children are the ones who develop allergies the most. About 3.9 percent of children have allergies, whereas 2% of adults have it. 6 Then, why are adults becoming more and more susceptible to this affliction? One possible reason is foods and every day household products are making people sick. Could it be that constant exposure to known hypoallergenic agents are causing allergic reactions to develop in adults who have never displayed any allergic reactions in their lifetime?
To understand why the sudden affliction of allergies is occu...

... immune system. The body’s immune system is beneficial to rid of illness and foreign invader our body note to be a threat such as parasite, virus, or bacteria but sometimes it can also reacts to a harmless substance. As a result to protect out immune system, the body manufacture a protective protein barrier called antibodies. This protective agent exhibit swelling and inflammation of tissues whenever an allergic reaction occurs as a response to eliminate the threat (Burks, Harthoorn,Van Ampting, Oude Nijhuis, Langford, Wopereis, & Harvey, 2015). In addition, the anatomical systems of babies are still developing in the sense that, they have small, sensitive airways in their lungs. In a situation of allergy contact, the airways become swollen as a result to rid virus and bacteria; and in response, babies start to cough, sneeze and can progress to wheezing and asthma.
Following my first sip of milk at the age of one, with the resulting hives and coughing that ensued, I involuntarily joined the community of fifteen million Americans afflicted by food allergies. Living everyday with additional allergies to peanuts, tree nuts, and shellfish has, out of necessity, sharpened my compulsiveness with ingredients and food preparation, but furthermore has spurred me to intervene on behalf of fellow members in this emerging epidemic. The Food Allergy Research and Education (FARE) national organization has been a source of education and support in my own life, and subsequently has aided my efforts to raise awareness among peers, and to nurture my advocacy involvement.

A recent study in 2015 reports that over 15 million people in America have food allergies that is 1 in every 13 people under the age of 18. Making it very likely that somebody in this room is part of these 15 million American’s who have food allergies. If you are somebody who has food allergies, or you know of someone who has food allergies, this speech will help you better understand more about food allergies, so you can deal with food allergies and more importantly be more careful around other people who do. So today, I am going to be informing you about Food allergies.
Most of you may not think of asthma as a killer disease, yet more that 5,000 Americans die of asthma each year. According to the Mayo Clinic web page, asthma also accounts for more that 400,000 hospital discharges annually. As the number of people with asthma increases, the more likely you are to come in contact with a person who has the disease. As far as I can remember, I have had asthma my whole life. My mother and one of my sisters also have asthma, so I have a first hand experience with it. This morning, I will discuss some interesting facts about asthma, I will specifically focus on what it is, warning signs, symptoms, causes, and the treatments that are used.
The human race is known to have developed numerous allergies to various known and unknown allergens. An extreme allergic reaction which can be “life-threatening”. Mydr.com.au, 2014) is referred to as Anaphylaxis. It is a “medical emergency”(Lloyd & Sisman,2013).Statistics indicate that maximum deaths occur due to allergic reactions to various medicines. Other causative agents can be insects, food, latex, hair dye, etc(Lloyd & Sisman,2013).

A food allergy is any adverse reaction to harmless food or food component that involves the body’s immune system (Anderson, J.A. et al., 1994). The term “food hypersensitivity” is referred to any pathological related to food ingestion which mainly divided into “food intolerance” and food allergy” according to molecular mechanism of action (Johansson, S.G.O., Hourihane, J.O.B., Bousquet, J. et al., 2001). There are several different types of adverse reaction involve immune system which helps the body to resist disease. Allergy reaction involve three component such as food allergen, immunoglobin E (IgE) and mast cells also basophils (Lemke, PJ., Taylor, S.L., Kotsonis, F.N. et al., 1994).

Patients who usually have allergies suffer from many symptoms due to the allergic reaction(s). Normally, your immune system protects you against invading agents such as bacteria and viruses. Otherwise harmless allergens (allergy-producing substances) cause your body to react as if they were dangerous invaders. In effect, your immune system is responding to a false alarm.
