Beer Allergy

In # 4: Food allergens in the news by Yixin4 Comments

In our side, some of friends always have allergic symptom to the body after drinking a beer, in addition to some small lump will be born, but also feel itching intolerable. In fact, this is because they are allergic to beer.   In the article about beer allergy, it introduced that nearly 1.2% of adults in the United States are allergic to wheat. It is one of the eight major food allergens. Generally, people who are allergic to wheat are also allergic to barley. In fact, there are two main reasons for beer allergy, the first one is the main component of beer allergy, and second one is alcohol allergy.   For the first reason, there is the content demonstrated in the article that although the main ingredient in beer is water, there are many other ingredients that may cause your symptoms. If you have an allergy, it is likely that you are allergic to a specific ingredient in beer. According to the brand, the ingredients may include malt, barley or other grains, such as wheat and sorghum, yeast, various colouring agents, or condiments and preservatives. Besides that, …

Peanut Allergy Related to Genetics

In # 4: Food allergens in the news by Cody2 Comments

This article discusses some of the new research done on figuring out how genetics can affect the way people get and keep peanut allergies. The researchers Dr. Denise Daley, and Dr. Ann Clarke have conducted research regarding the specific genes that can play a factor in whether a person develops a peanut allergy. They were able to pinpoint a gene called c11 orf30/EMSY (EMSY) that may be the culprit for the development of peanut allergies. The research that was conducted was on many individuals affected by the allergy and many without to find a key difference. The difference was found to be the EMSY gene and can be a deciding factor on the likelihood that a person develops a peanut allergy. The article explained that previously they had been looking at a different gene to be the likely culprit, however, that was not determined in the study. Looking at the research done on to me shows that there are improvements and a progression toward figuring out the complexities associated with food allergies. I find this article extremely fascinating because it …

A New Cure

In # 4: Food allergens in the news by Sydney4 Comments

A recent study shows that researchers may have found the exact cells that cause certain allergies. Now, since this group of cells are now made known, scientists may be able to come up with a way to block these cells, which in response would block your allergies. This group of cells are known as the TH2 cells. Scientists do have a treatment for peanut allergies which basically forces your body to become immune to the allergen by exposing your body to increased amounts of that specific allergen which in result helps the tolerance of the allergy. According to this article “We saw a dramatic decrease in TH2A cells after the success of the treatment,” stated by cell biologist Erik Wambre. Scientists are still researching new ways to stop the development of these cells in order to help allergy patients. This article came of interest to me because I’ve witnessed my sister dealing with awful allergies during the spring. Her allergies aren’t food related but this study is geared to help all allergies that caused by the TH2 cells. In witnessing …

Food allergies are on the rise

In # 4: Food allergens in the news by Gerardo0 Comments

Food allergies within the US are on the rise and there’s no denying that.  Research from the CDC tells us that food allergies in children have grown around 50% between 1997 and 2011.  That’s 1 in 13 children in the US.  Around 90% of these reactions come from milk, eggs, peanuts, tree nuts, soy, wheat, fish and shellfish.  These allergens cause an average of 300,000 allergy-related trips to ambulatory care every year by children under 18. There are 2 main theories for the rise in  food allergies: the hygiene hypothesis and gene expression.  The hygiene hypothesis is the thought that keeping our kids too clean has caused them to develop these reactions.  The reasoning behind this hypothesis is that a lack of exposure to these foods as a child makes the body mistake the protein for an invading germ.  Dr.  Leigh Vinocur believes that the overuse of antibiotics, and drugs related to these, cause gastrointestinal changes that affects how the immune system perceives a food protein. Another area being studied as being a cause in the rise of food allergies …

Allergies no more

In # 4: Food allergens in the news, Assigned Posts by Alexis1 Comment

I found an article from NPR commenting on how it is common for children to outgrow their food allergies. The study explains a new test, called a food challenge, that is used to determine if one no longer has an allergy. Basically, whoever is being looked at will eat the food that they were once allergic to and see if there is any reaction. Of course this test is done under medical supervision, and the person of interest begins with eating essentially a crumb. If that goes well they can move up to a larger portion and “pass” once a certain amount is hit such as a whole egg for those allergic to eggs. Out of the over 6,000 patients the study assessed, 86% of them passed, 14% has a mild reaction (symptoms treated with Benadryl or an antihistamine), and only 2% had serious reactions (needing epinephrine). That being said, these patients were low risk to begin with. Based on the information in the article, this seems like a great discovery in the realm of food allergies. According to the …

Know Your Allergies

In # 4: Food allergens in the news by Elizabeth1 Comment

This article described that the best way to find out about an allergy is through an oral food challenge. An oral food challenge is where the person is given a small dose of food by mouth while being supervised by a board of certified allergist. It is said to be the “golden standard” for determining if someone is allergic to a food. The American College of Allergy, Asthma, and Immunology (ACAAI), which is a professional medical organization of more than 6,000 allergists-immunologists and allied health professionals, examined the results of 6,327 oral food challenge studies that were conducted at five food allergy centers around the US. They determined that only 2% of people had severe reactions, also known as anaphylaxis, and only 16% of people had reactions at all. The 16% of people that had minor reactions only suffered on one part of their body such as hives on their skin. I personally think that an oral food challenge is very important. If someone thinks they are allergic to something but isn’t for sure then they should do the challenge …

The Relationship Between Food Allergies and The Entire Dietary Habit

In # 4: Food allergens in the news by Danyan1 Comment

According to the Centers for Disease Control and Prevention, it shows that more than 50 million Americans have some food allergies problems for one or more kinds of specific foods. Food plagues about four percent of adults in the long term. However, food allergy symptoms are not only common in adults, but also for babies and children. In reality, food allergies are estimated to affect four to six percent of babies and children. Based on the data as mentioned above, food allergy is a subject which can not be ignored. Research for now considers there are eight types of food account for almost ninety percent of food allergies including eggs, milk, peanuts, tree nuts, fish, shellfish, wheat, and soy. Some symptoms of an allergic reaction may involve the shortness of breath, wheezing, weak pulse, vomiting, and so on. But more importantly, sometimes, an allergic reaction is a life-threatening illness. (American College of Allergy, Asthma,& Immunology) Recently, I read an article called “Babies that eat fresh foods instead of processed foods have fewer allergies.” In the article, it pointed out an …

Do farm kids have fewer allergies?

In # 4: Food allergens in the news by Emmalea5 Comments

I have always heard that exposure to the farm animals at a young age could help prevent allergies and asthma, and now this study out of Zurich University has confirmed just that.  The study, “How cats and cows protect farm children from asthma,” found that non-microbial molecules present in farm cats and cows can protect children from developing allergies and asthma.  One of the molecules is sialic acid.  The acid is not produced by humans because of a genetic mutation, but it is produced by many vertebrates.  Humans absorb sialic acid when they come in contact with animals that have sialic acid or when they consume food from animals.  The sialic acid is integrated into the human’s glycoproteins and trigger an antibody reaction.  The researchers compared the antibodies in a thousand children and found farm kids have many more antibodies than non-farm kids.  The researchers also found that the sialic acid acts as an anti-inflammatory in the immune system.   Additional studies have found that the microbes present in dust on farms can reduce allergies.  This study exposed mice to …

Children’s Food Allergies

In # 4: Food allergens in the news by Emily1 Comment

This article is about a case study written by the AAAA (American Academy of Allergy Asthma and Immunology) and performed by “The Health Nuts”. It’s called “Prevalence of Food Allergy in Australia remains remarkably high”. In this study, they wanted to test preschool aged children for food allergies. “The Health Nuts” study in Australia was one of the first to use a population based sampling. They used “Oral Food Challenges” and “Skin Prick Tests”. Their main goal was to find out approximately how many children from age one to four had food allergies. 11% of children had a confirmed food allergy at age one, and this was reduced to 3.8% by ago four. Peanut allergy was the most common, followed by egg allergy. Overall, 40-50% of children aged one through four had experienced symptoms of at least one food allergic reaction by the time they were four. Even though the amount of food allergies in children decreased from age one to age four, they are still quite high. The question to be asked here is why is the percentage so …

Peanut Allergies

In # 4: Food allergens in the news by Justin0 Comments

True, some would say that peanuts are a concern for infants and parents are afraid to test for allergens by trial and error, but what if it can be prevented? Canadian Asthma Primary Prevention Study has been studying a groups of women and infants for this exact reason since 1995. This is an interesting study performed because it allowed the scientists to be able to think back to ways that can help improve allergen prevention / immunity. By exposing infants in the womb to allergens, it can make them less susceptible to becoming allergic to them within the first 7 years. The results of the study are:   Overall, 58.2% of mothers consumed peanuts while breast-feeding and 22.5% directly introduced peanuts to their infant by 12 months. At 7 years, 9.4% of children were sensitized to peanuts. The lowest incidence (1.7%) was observed among children whose mothers consumed peanuts while breast-feeding and directly introduced peanuts before 12 months. Incidence was significantly higher (P < .05) if mothers consumed peanuts while breast-feeding but delayed introducing peanuts to their infant beyond 12 …

Little by little

In # 4: Food allergens in the news by Chuan1 Comment

Food allergy has been running around in history long enough for humans to care about it. The big 8, namely milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans are the most common allergic reaction conducing food. It wasn’t a new thing for me as both my sisters used to have allergy towards eggs, and shellfish, though the allergy wasn’t severe and faded as time pass. The problem in my family made me wonder if allergies can be prevented, thus the studied article in field of allergy cure. “Towards a Cure for Food Allergy” by J.M. Skripak and H.A. Sampson has just what I am looking for. The article talks about the many types of treatment for different allergies, which I find helpful towards creating a world where people can enjoy food as they like, without any physiological negative feedback. As of the article, hydrolyzed formulas might be associated with lower risk of cow milk allergy. Milk allergy is not to be confused with lactose intolerance, while they sound similar, lactose intolerance is caused by the lack of …

A Night of Normalcy

In # 4: Food allergens in the news by Casey3 Comments

It is getting to be most peoples’ favorite time of year. Temperatures are dropping and the leaves are beginning to change from green to all shades of orange and red. Stores have taken note of the change in season and have begun displaying fall decorations along with all kinds of seasonal squashes and other kinds of produce. Supermarkets and shopping centers line their storefronts, or a few aisles, with orange pumpkins of all shapes and sizes for families to purchase to take home to carve or to use as decorations. Recently, within the last few years, a new color of pumpkin has hit the shelves. These new pumpkins are teal, but not as a result of genetic modification or biotechnology. In most cases, orange pumpkins are painted or the teal pumpkins are made of molded plastic. The Teal Pumpkin Project was launched in 2014 by the nonprofit Food Allergy and Education (FARE) group. For kids, fall means picking their favorite superhero or princess and dressing up as them for Halloween. Most kids go trick-or-treating and race to see how much …
