The Digestive And Immune System

The alimentary canal is where the digestive system takes place; it has different components in order for food to be thoroughly processed. The digestive system is composed of an enteric nervous system and has four layers of tissues; the mucosa, submucosa, muscularis externa, and serosa. Food enters through the mouth and passes through the esophagus, stomach, small intestine, and the large intestine before exiting the body through the anal canal. This occurs within the digestive system in four main steps; ingestion, where food enters through the mouth, digestion where food is broken down physically and chemically, absorption where nutrients are taken to their desired organ for use in the body, and elimination where waste is removed from the body due to being useless or toxic.When it comes to the human body there are plenty of components that we take for granted. Think about it, when was the last time you dwelled upon the function of your saliva or pondered on the responsibility of the esophagus? If you are like me, the answer to the question is simple, never. It is because our body is one of the greatest and yet most underappreciated machinery known to man. Within that system, which tends to get a lack of appreciation, stands alone one main process that we utilize on a daily basis and rarely give credence to its importance. This process is known as digestion, which occurs in the alimentary canal also known as the digestive system. The digestive system consists of the

Thesis Statement: Peanut allergy, a type of allergy that is very common these days among children and which results in many deaths yearly, now might have a cure, and today I will talk about the peanut allergy and its symptoms and the new proposed cure for it.

In a recent survey from Wesley Burks, 1.3 percent of adults are affected by peanut allergies. He states that peanut allergy is one of the most immediate hypersensitivity reactions. He supports his claims by explaining that 30,000 food induced are seen in the emergency room, 80% of them were caused from peanuts or nut trees. 200 of them were fatal. The results of the present study will help in the evaluation of future immunomodulatory treatments for food allergy and in studies that examine the natural history of food allergic reactions. Individuals allergic to peanuts and individuals allergic to eggs had a similar Th2-skewed cytokine response. Peanut allergies are infrequently outgrown while egg allergies are outgrown by 4-5 years.

Tree nuts include hazelnuts, walnuts, almonds, cashews and pistachios (1). Peanut and tree nut allergies are the most common cause of life-threatening allergic reactions (2). Peanut allergies alone account for over 50% of anaphylactic shock cases in the U.S. (12). Proteins found in nuts are the primary causes of these food allergens. The proteins found in nuts include soy and carob (5). Nut allergies tend to develop in childhood and usually last a lifetime (4). Peanuts and tree nuts account for 0.8-1.3% of allergies in America (12). In the U.S. alone, approximately 3 million people report having a nut allergy (4). Food processing techniques, increased peanut consumption and early childhood introduction of peanuts may be responsible for increasing the prevalence of this allergy (5). Individuals with a nut allergy should avoid consumption of snack foods that have been reported to have high levels of nut cross-contamination. These foods include chocolates and chocolate-based foods, cookies and biscuits, cereal bars, dried fruit bars, nut mixes, baked goods, candies and ice cream

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.

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

Food allergy reactions are caused when the immune system overreacts to a certain food or substance, which identifies it as a danger, triggering a protective response. Food allergy symptoms usually range from mild to severe reactions. Symptoms of an allergic reaction may involve the skin, gastrointestinal tract, the cardiovascular system, and the respiratory system. Some symptoms are hives, vomiting, stomach cramps, wheezing, shortness of breath,

Food allergies are the major trouble for United States. The statistics states that 1 in every 13 children has one or any kind of food allergies in the United States and there are approximately 50% increases in food allergy rates from 1997 to 2013 (Centers for Disease Control and prevention, 2013).There are 8 types of food allergies most common in United States like milk, peanut, fish, shellfish, wheat, soya, eggs and tree nut (Branum, A., Lukacs, S., 2008). Peanuts, shellfish and tree nut allergies are generally lifelong allergies (Branum, A., Lukacs, S., 2008). Most often food allergies don’t lead to death but it is very annoying for the people. In food allergies, the immune

A recent study by the American Journal of Clinical nutrition (2011) found that over a 15 years period, men and women who consumed nuts had a 51 percent lower risk of dying from an inflammatory disease like rheumatoid arthritis compared with those who ate the fewest nuts while another study found that subjects with lower levels of vitamin B6 found in most nuts had higher levels of inflammatory markers while there is no definitive arthritis diet. Vitamin B6 functions in the metabolism of amino acids, it is essential for formation of red blood cells and metabolism

This study is an attempt to provide information to families of children suffering from food allergies and suggestions to manage their new reality, as well as to bring awareness to the general public. A person can become allergic to any food at any point of their lives, whether as a baby or as an older adult, but the most common reported allergic reactions are to eggs, dairy, peanuts, tree nuts, fish, shellfish, wheat and soy. Although many feel that seeds should also be included.

Food allergies are becoming increasingly prevalent across the world, affecting more and more children each year. There are many misconceptions surrounding food allergies and fad diets, along with misinformation, aren’t helping the cause. The lack of consensus regarding how to define food intolerance and food allergies makes the already complicated issue more confusing. Some theories claim that the increase in food allergies is attributed to modern hygiene practices, where others point to the increase of food preservatives. The exact etiology of food allergies is unknown, although there is some scientific information available on prevention. The subject of food allergies is important because it is life threatening and the potential severity

One of the many researches being done is to look at how we can provide a better outcome of an allergic reaction. They took the approach of oral immunotherapy. They believe that oral immunotherapy lead to desensitization and with early intervention, it would improve the efficacy of peanut tolerance. When patients accidentally ingested a small amount of peanut, their body can still tolerate and proved a smaller allergic reaction as compared from before. It is concluded that although this is not a cure, but it may lead to improve long term

According to the U.S Centers for Disease Control and Prevention, more than 3 million Americans now have some sort of a nut allergy. Children, in particular, seemed to be especially sensitive to nuts. The number of children living with a nut allergy have nearly tripled from 1997 to 2008. This number is staggering and begs the question, why is there a significant increase in nut allergies for Americans?

Allergies have affected peoples lives for as long as time. Cutting out certain foods from ones diet due to allergies can be a burden. Peanut allergies statistically are known to be one of the most common and dangerous children face today. As time has gone on this allergy has seemed to grow more and more common within the country. Peanuts and or peanut products are almost in every food product. Due to the prevalence of the product, one must keep a close watch on the ingredients so an anaphylactic shock or reaction is not present. If not caught or treated an anaphylactic chock or reaction can ultimately turn deadly. According to recent studies, introducing peanut and peanut type products early in life from the ages of four months to eleven months prevents the development of the

When a person prone to allergies is exposed to an allergen, the immune system reacts in a hypersensitive manner. The person has a number of symptoms, including scratchy throat, itch and watery eyes, sore throat, blocked or running nose and so on. He can also have breathing problems, irritations in the esophagus and rashes in the skin.
