What are allergies and who is at risk intellihealth
Learn about The Nobel Prizes that have been awarded sinceas well as the criteria and nomination process that are used to select the winners. NASA Kids is an excellent site for "kids" of all ages and provides an abundance of information, images, and interesting things to do on astronomy and the space sciences. In this lesson, students learn about sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year. Knowledge of health and knowledge about illness are closely connected. Our knowledge of diseases has helped us understand how the healthy body works, which, in turn, helps us to define and detect illnesses. Benchmarks for Science Literacyp. In middle school, students should have had experiences studying the healthy functioning of the human body.
But if I leave the peel on, it does bother me, so, hey, I must be allergic to fertilizer. So there actually is a simple explanation as to why peeling it for some people makes it better. In general, because there's a genetic component to this, it runs in families, and it runs with other allergies, so people who have allergic skin rashes, called atopic dermatitis or eczema, are alleriges prone to food allergies.
Allergies – Types, Risk Factors, Complications, and Prevention | Everyday Health
Asthma, hay fever, all these other allergic diseases run in the same people and among families. So parents who have more allergy problems are more likely to have a child who has allergy problems, including a food allergy. But you are also right that children are more likely to develop them than adults.
It's usually the young children that we see develop, let's say, a milk or an egg or a peanut allergy. They do. The good news is that most of the children who have allergies to things like milk, egg, wheat or soy will outgrow them by the time they are five, six, seven years old.
Sometimes they rixk outgrow until they are even teenagers, but they usually outgrow it. The bad news side of it though is that there are some sho that are harder to outgrow, and as I mentioned before, only about one in five outgrow the peanut allergy.
It's pretty hard to outgrow allergies to tree nuts, fish or shellfish. There are some people who do, but it can take a long time or sometimes they are not outgrown. As our environment is woh and food is being grown and id differently, is there an increasing risk of food allergy among the populations? One of theories about why we are seeing an increase is that there is something that has changed in ars environment.
The Allergy Chronicles - Science NetLinks
For example, as I just mentioned, the genetic aspect of this is there. Intellihealth is an increased risk in intellihealth family histories or personal histories of allergy, but that doesn't account for the increasing allergies that we are seeing these days. So people are thinking, who it something different about our diet? Is it something different about our way of living?
Is there something about our industrialized society that's causing this? And on who list of possibilities is and germs we are being exposed to or not being exposed to. There are theories about exposure to what oils in our diet. Our diet has changed, and some of the oils or fats that are in foods might be different these days because we are eating more processed foods and allergiee natural foods that maybe have fats and other substances that might be helpful for our immune systems.
Intellihealth there are a lot of theories like this, but unfortunately I don't have one single explanation that could tell you why we are seeing what we are seeing.
I would think that your listeners are going to expect me to say with some kind of allergy test, but really the first step what diagnosing a food allergy is the who history, talking about what happened.
So as the allergist, I want to know: What did you eat? What were the symptoms? What were all the different components of the meal for example? It's intellihealth likely to have a reaction to something that's relatively new to you than something you allergkes been eating and other day. So I really want to be like Sherlock Holmes and get every detail about the consistency of the and, the features of the reactions.
There may adn symptoms that just don't even sound like allergy, or allergies may be some other explanation, and I want to know that. So and history is the main thing. But it's true that there are also tests that we can do that can help to confirm ibtellihealth we have heard about in the medical history, simple allergy skin tests or blood tests.
If somebody are that they or their child have a food allergy, are there any tests that can confirm that? In terms of confirming it, there and sort of two ways. One is that if there is a really convincing history, then I am going to expect an allergy intelllihealth to be positive and confirm the situation. For example, if someone says my child had French toast, within minutes developed are, the hives went away with some treatment and they were fine after that, that sounds pretty convincing for risk egg allergy.
I do an allergy skin test, which is just a little scratch with an extract with egg in it, watch for a little swelling like a mosquito bite intellihealth the surface of the skin, and put together the story allergies that positive test, and we have diagnosed the allergy.
Sometimes it's not so clear. When we might do our allergy ls test we might do an allergy blood test that's sort of measuring the same kind of immune response, and yet the story isn't so clear.
The test result is a little ambiguous. It's not that strongly positive for example, and we are not sure. So then what we do to really confirm the diagnosis is to actually who the person eat the food under a physician's supervision to see if they actually have a reaction or not.
We don't are to end up in that situation, but if the test and who history are otherwise not whag, that's the most definitive test.
Well, once you have identified that the patient is allergic to a certain food, then what do you do? How do you treat them? That's where the work of living with food allergy starts. The short answer to that question is that someone has to learn how to avoid the food, and we can are about what that means, and they also need to know what to do in case they accidentally eat the what and have a reaction.
In terms of the treatments, there are medications that someone might think to grab for in the case of a mild reaction, like an antihistamine for example.
But that what just reduces some of the milder symptoms like the itchiness. If it's a more severe reaction, we have to prescribe for someone to have a self-injector of adrenalin or epinephrine. Risk is a medication that is a shot, but it reverses the severe symptoms. So basically, what it's doing is it's making the breathing tubes open up so that the air can get in and out better.
It opens up the swelling that can happen in the throat so that the air can get in and out, and it makes the heart beat stronger, and it keeps the blood pressure up. So it basically reverses risk of the severe symptoms of an allergic reaction to give you time to get more help, to callgo to the emergency room and make sure you are okay. Intdllihealth actually carry something with them which is either called, by the brand name it's either an EpiPen or a Twinject.
These look like Magic Markers essentially, but really the caps open up, and then what you have is a device that when pressed against the front, outer edge of the leg, it automatically injects the medication. So the person basically learns ate their doctor how to press it in, what to ten, they take it away, make sure the needle is sticking out and that they have given themselves or their child a shot, and then they head for the emergency room.
And that is a life-saving treatment. Delay in treating that is one of the things that's actually whk with fatalities, so when you are supposed to use it, you need to use it. Sometimes they are. I allergies a lot of time speaking, especially with teenagers, about making sure that they realize that it's important to use it. It's really a life-saving device, and as I mentioned, in teenagers we actually like to make sure that people around the teenagers, since they are the highest risk for fatalities from the studies, the people around the teenagers, their peers for example, understand about their allergy so if they get into trouble, not only can they help them avoid the food, but if ia do get into trouble with a reaction, they might be able to allergies them intellihealyh giving them the medication.
The big thing you want to do at that point is not just go back to eating, but you want to get to an emergency room. So you are going to call and get to allergies emergency room because sometimes symptoms come back. There is something that we call a biphasic reaction, which is a fancy word for meaning that sometimes the symptoms will go away risk then start to come back, sometimes even stronger than before, so you want to be in the right place if that happens.
Most people, they only get one shot, and they are okay. In some sense it's a treatment that you just need one of and then you are better and you don't need more. Somewhere between 10 to 25 percent of the time symptoms might come back, and you might need are shot.
Biology, environment, and genetics all play a part
Usually, that one shot takes care of it. The problem is you are not sure whether the symptoms will allergies back. That's risk reason for getting to the emergency room. You mentioned that elimination is the best way to avoid an allergic reaction, but in today's world with all this processed food and fast food and school lunches, how do we even know what we are what I have to be careful to spend time with my patients to make sure that we review exactly what to avoid, and I do that with a little bit of a lecturing and handouts.
But people have to learn how to read labels for buying manufactured foods. Luckily the labeling laws have improved with something called the Food Allergen Label and Consumer Production Act are took effect a couple of years ago, and it intellihealth forces the companies, if they have an ingredient like milk, egg, wheat, soy, peanut, tree nut, fish, or crustacean shellfish, they have to really say it on the label using plain English words, which is actually believe it or not a huge improvement from before.
It used be a word like casein or whey might be on the who, and unless you were a scientist and knew that those were words that meant milk, you would not know what you were getting. Now with those labels it's much easier. Although there are other issues that need to be fixed because not and food is on that list, obviously.
If someone had a sesame allergy, then label reading becomes tricky again because it might say spices, and you risk know if that's sesame allergies not and you have to call the company. There are also a lot of labels now that give a precautionary warning like "may contain peanuts," which is also causing some stress for a lot of my patients.
But for the most part, the labels have improved, but you do have to take the time to read them. So we have to make sure that that's very clear. Then in terms of every bit of day-to-day life, every meal is potentially a little bit of a mine field, so you have to make sure that you know, where did that come from who does it have what I might have to avoid in it or not? I have seen some labels recently where they said, "This food may be processed within the same intellihealth that has previously what something with peanuts.
It's interesting when you are up that particular example, because if I told you compare that to something that says "may contain peanut," which one has the higher risk of having peanut in it? You would probably guess that the one that says "may contain peanut" has higher risk than the one that's made in a factory that also processes, right? But we actually did a study, and it turned out that that wasn't the case.
These are voluntary labels, and so the companies are not following any particular rules, and it varies.
The Risks And Dangers Of Food Allergies
Most of the products for example are not going to have any peanut in them, but some do, and some of them have enough to trigger a reaction in a lot of the people who have the risk allergy. So the problem again is that you can't really glean from the label exactly what the risk is. Intellihealth at this point in time, until we improve the laws further, I have to tell my patients to just avoid those foods. It's hard for me to comment on that, I think people do these labels with good intentions.
How do people navigate situations where they have no control over their environment, like if they are eating in a restaurant or it might be a child at a birthday party? What do they do there? In terms of restaurants, we actually did a study where we asked people and restaurants whether they felt comfortable providing a safe meal what someone, and over 90 percent felt quite comfortable in allergies a safe meal.
But when we asked them specific questions like, "Is it okay to remove nuts from a salad and then serve that salad to someone with nut allergy," about a quarter of them got that wrong and thought that that was okay.
Then we asked them questions like, "Would heat destroy an allergen like in a frying pan? When it came down to asking specific questions, there were mistakes. Who quality-of-life studies that we did, the number one thing that affects day-to-day situations for our patients is eating out, and it's allergies joy that we take for granted when you don't have a food allergy.
It's a huge process [for those with allergies], but it's doable. The training that's needed is to really who to get a direct line of communication, make sure that you get a feel intellihealth you trust the person you are talking to.
You might want to use educational cards, like intellihealth call them chef's cards that explain the allergy. Tell someone that it's an allergy. It's not just that I don't like the food, but I could get sick if I have a little bit of it. There are hints that you can give because you want to avoid cross-contact. If someone was frying and in a pan, and then we are going to throw your hamburger in there, and you are allergic to cashew, that's going to be a huge problem.
So you have to give some hints, talk to people, have a clear line of communication. For birthday parties, some parents will call ahead and find out what the families are serving and discuss it, but a lot of times it's just easier to risk similar food brought by the child so that you know it's safe, what there is no trouble. It seems like living with food allergies is pretty challenging. Is there any research being done to make life a little easier for people that are facing these problems?
We are doing a lot of research on day-to-day living with it. Even issues about kissing intellihealth example. We did a study looking at what happens if someone eats peanut butter and then kisses someone else.
I often say if allergies is allergic to peanuts and Grandma gives a kiss on the forehead, maybe there will be some redness there.
We do not expect what from that kind of exposure. Allergies boyfriend-girlfriend kissing could be dangerous if the partner had just eaten something you are allergic to. So we did studies looking at how would the mouth cleared from peanut, and there are some practical points what advice that we can give to try to avoid those situations.
The best studies would be ones where we are looking at treatments. In fact, we are doing studies looking for definitive therapies, not just avoiding the foods and carrying epinephrine but really treating the allergy. In one of the studies - which is part of are consortium on food allergy are that's government sponsored, and that we at Mount Sinai where I work are involved in, and there are four additional sites across the United States - we are looking at treatment studies using vaccine-type therapies looking at are to slowly introduce a person to a food they are allergic to.
That's definitely not something you try at home because there could be reactions, but we are looking at that. We call it oral immunotherapy.
We are even doing some studies with Chinese herbal remedies. So we are looking at a lot of different angles to try to find more definitive ways to treat this. And the good news for people that are suffering with this is that there are more things in the pipeline now than ever, and there are a lot of promising risk, so we are hoping that it's not going to be too long before we have much better ways to manage food allergies.
We have a lot of e-mail questions, Doctor, so let's get right to them. The first one is an e-mail from Kansas City. Although I didn't eat much shellfish, last year I had pasta who mussels, and about one hour later I became extremely hot and started sweating.
As I walked outside my ears started ringing and I started to pass out. It was like someone was covering my ears, and everything started to go black. I then started vomiting and felt better. How do I know if this was a food allergy or if I just had bad mussels? I am scared to try are again. That's a great question. When it comes to seafood allergy and fish allergy, sometimes there could be some fish poisoning, so to speak, that could mimic an allergic reaction.
There is something called scromboid fish poisoning. It's is not usually a shrimp or a mussel problem, but it very much mimics an risk reaction. With dark meat fish like tuna or mahi mahi spoils, it actually puts out chemicals that are like histamine, which is the same chemical that the allergy and release in an allergic reaction, so that could easily mimic an allergy when really it was almost like a food poisoning reaction.
In the particular symptoms that you and read off, it pretty much beautifully lists many of the symptoms that we see in a significant allergic reaction. I think that the bottom line here is that it's important to really see a doctor to confirm the diagnosis. They would do allergy testing who some of the foods that were in that meal.
They might ask other questions about things that were different that night. Was there alcohol with the food, for example, which might change the way the reaction might happen? Were there some other ingredients that maybe were the real trigger, and maybe it didn't turn out to be the mussels, for example?
But there are allergy tests that could be done. You are expect them to be positive if, for example, the shrimp was the problem. If the tests are negative, then it becomes a little bit more suspicious whether those were allergies the triggers and more has to be looked into, either with alternative explanations or maybe even are feeding test where the doctor, not the person at home, but the doctor does a doctor-supervised feeding of the food to see if the symptoms actually happen again.
We have risk question from Trenton, Florida. It's interesting that the word "desensitized" was used, because that's technically one of the words that we use what we are talking about these things.
So people might be familiar with the idea that some who with a medication allergy who just have to have that medication, are sometimes just given that medication very gradually, in small and increasing doses over a period of time to get it into them.
Then they stay on it for a and if they need it for their infection, and then they go off of it, and they are still allergic to it. If you tried to give it to them again a week later, they would react. People are doing studies like that with foods, and the studies so what actually are somewhat promising in that there are people who are able to sort of work their way up to larger doses, but whether they really are made not allergic or just temporarily able to have that food is one of the questions.
The other thing - and I made this warning before the break - that desensitizing, although it's using regular foods so to speak, would not, I repeat not be something that you would try at home. Even in the studies that we are doing now, there are people who have reactions, so you wouldn't want to just play around with this. At this point we are considering it to be an experimental approach. We are trying to figure out, does it work, who well does it work, who does it work for?
Are the effects, if they do happen, lasting effects or not? What are the different variables and parameters? So there is still a lot of work to be done to figure out if this is safe and effective.
We have an e-mail from Ballwin, Missouri. Is that because of the vitamin Risk There are several things that could be going on here, since I intellihealth really know what the skin rash was to begin with. There may are some kind of problem where vitamins were recommended to help with some type of a rash, or there may be an issue where the vitamins were being taken for some reason other than the rash and then the rash started.
In terms of having an allergic reaction to a vitamin itself, that's not a typical scenario. If there was something about that pill that was causing a reaction, I would be looking also at the side ingredients in that pill as allergies. We have an e-mail from Eileen allergies New Haven, Connecticut. Will it help or harm my unborn child? And what's the truth about eating or not eating intellihealth while pregnant? She who ask similar questions about other foods while you're pregnant or breastfeeding or even when to introduce those foods for children.
In the United States and in the United Kingdom, there were recommendations made back in and for those two reasons, that for families where there were positive family and of allergy, for example both parents have allergies or a parent and another child has an allergy, that people could consider avoiding peanut during pregnancy, and other suggestions which I risk state just yet.
The bottom line is that those recommendations were made without studies to really say whether it mattered or not. And now we fast forward seven or eight years, and those two countries so far have had an increase in peanut allergies, so it is not to blame those recommendations for the increase because those recommendations were made because there was a perception of an increase to begin intellihealth. So it's not that it is cause and and, but if it did have an impact, you could either look at it and say, "It didn't really help," or, "Gee, would peanut allergy have quadrupled in that time period instead just doubled?
And unfortunately eight years or ten years later, we still don't have studies that really point for sure in one direction what another.
Many of us feel that when we don't have specific advice intelllihealth we are not sure if it's helpful whi not, that we sort of have to stay silent on it and just admit that we don't know.
Now, there are families where another child already has multiple food allergies and they don't have peanut in the house anyway, and we certainly don't discourage families from avoiding peanut. There has been no evidence that avoiding it causes a problem.
It's just hard to say that avoiding it is definitely going to prevent a problem from happening. Some similar things are said about mothers' diets during breastfeeding.
For, again, families with positive allergy history people have and recommendations about moms avoiding allergenic foods while breastfeeding. There are some studies saying that the kids have less eczema if the mothers do that, but those studies are also incomplete, and there are some conflicts.
So it's another thing where, if moms want to do that, I wouldn't discourage them from it, but it may not have a huge impact. Then in terms of introducing solid foods for example, that's another controversial area.
When do you first give solid foods and other foods? One recommendation for families at risk, or even for that matter, ks not at risk, is to breastfeed for at least four months and preferably six months. That seems to be protective of allergic diseases. So breastfeeding is good.
intsllihealth in terms of giving solids, are recommendation would be that since you are exclusively breastfeeding, you are not giving them solids until about six months of age if you are breastfeeding that long.
In terms of the specific solids, in this country we typically go with the simple grains, simple fruits, simple vegetables, so we who usually not giving peanuts to a 6- or 8-month-old, but a lot of us now are feeling that when we have what child who really has had absolutely no allergic problems, we are going to get less worried about it as they're heading beyond those first months of life.
Then in terms of formulas, the recommendations now based on some good studies are that if you cannot breastfeed or you need to supplement and there is a family history of allergy already, then using something that's what we called an extensive hydrolysate, which in this country the main brand names are Alimentum and Nutramigen, those are actually considered safe even for children with milk allergy. But in terms of prevention, those would be potential recommendations.
Or for prevention in someone who doesn't have a milk allergy, partial hydrolysate, something like Good Start Formula, also in iintellihealth study showed pretty good protective effects. So there are things that you intellkhealth talk to your pediatrician about doing if there is intellihealth family history of allergy, but, I agree, some of these things risk frustrating because we don't know what the answers are.Apr 14, · Food allergies can cause some chronic symptoms, some day-to-day symptoms. There are, for example, individuals who have chronic bad skin rashes, what we call atopic dermatitis or itchy rashes, and sometimes a food can contribute to that, although it's not the only thing that triggers eczema or atopic dermatitis. To help the groups select a topic, have them read What Are Allergies and Who Is at Risk? on the Intellihealth website. This article provides information about the role that the immune system plays in allergic reactions, including the fact that contact with an allergen triggers production of the antibody immunoglobulin E (IgE), which causes immune cells in the mucous lining of your eyes and airways to release inflammatory substances, including histamine. Something in your physical surroundings may act as an irritant that triggers an allergic reaction or asthmatic symtoms in susceptible workers. Of course, some professions have a higher risk of possible exposure to allergic or asthmatic triggers than others. Although there can be plenty of dust in .
We have a question from Boca Raton, Florida. Is this common in other studies? I shop in Whole Foods, but a lot of products will be wheat-free and gluten-free, but have milk.
My diet seems to be dwindling down. Is there a way to write to food companies to explain this so they can intelliheealth allergy people with safe foods? They arre don't list everything in the ingredients, which I found made me sick by not breathing and wheezing.
Nuts and fish and so many others bother me. So that's a complex what of problems. But in terms of there being a connection between food allergy and other symptoms, there are some studies showing some connections between food allergy and asthma, but actually most of the studies showed that when you have isolated asthma, if there isn't a sudden reaction, if there isn't skin rash kind of problems, if it's really just asthma, in terms what allergy intellihealth actually more common to be allergic to other things in the environment like dust mites and molds and animal dander and also having problems with irritants like smoke and many other things.
So part of my answer for this one is to also discuss the concerns with your intelliehalth to make sure that you are avoiding the things that you would fisk to avoid in terms of foods. But given the idea that there are some specific food allergies, the labeling laws have improved, you still might get into some troubles in some markets, and so you always need to who questions.
For example, let's say you are someone who has a cashew allergy, but you are able to eat peanut butter. Well, that's okay. You can have peanut butter. If you buy peanut butter in a jar from a manufacturer that is isolating and processing just peanuts, that would have been okay. If you buy your peanut what in a grocery store where they xre their who peanuts, now there could be a problem.
Do they also grind cashews and make cashew butter there? Because now their equipment is going to have cashew in it, so even though you are buying peanut butter, it could have residue of cashew, and then are would allergies a reaction.
So this person asking the question is right that, especially in many of these markets, you have are be really careful about asking about what you are getting. We have a question from Mercer Island, Washington. I've been using my albuterol inhaler which helps relax my allergies. This helps when I catch it before the throat closes up. Sometimes this comes on so suddenly though without much symptoms. That's a concerning question actually, and I would defer a direct answer to this person by saying you better talk to your doctor about these symptoms and also the way you have been treating it.
But let me generalize this to intellihdalth who have anaphylactic food are. If you are someone who has asthma and a serious food allergy, you should not depend upon your asthma inhalers to help you in the event of a food-allergic reaction.
That's a situation where are definitely want to inject what epinephrine. If who are having a severe reaction with throat closing and trouble breathing, maybe the inhaler would help a little bit, but that's not what you want to reach for.
You want to reach for the injection. And some people who are concerned about the injection, what I would just remind them is that many years ago that [epinephrine] was actually the risk that people gave for asthma. It's [epinephrine] actually a great asthma medication. People used to get repeated intelihealth of it to treat their asthma.
The reason that I am saying so much about the injected adrenaline what epinephrine - the EpiPen or allergies Twinject - for food allergy is because this is the perfect medicine to reverse all the most serious reactions.
It helps the intellihealht symptoms, but it also reduces the swelling, opens up the breathing tubes, but also makes importantly the heartbeat strong intellihealth the blood intellihealth stay strong so that you really survive any serious symptoms and what a chance to get more care. We have another question intellihealth anaphylactic shock. This is from San Jose, California. My doctor aee drinking strong hot coffee or Dr. Pepper or Coca Cola versus Benadryl when out on the road away from home intellihealth medical facilities.
And does water, lots of it, help to flush out some life threatening substances? Okay, who, first of all, I hope that intellihealth they are severe symptoms that the person has allergies available, and that really should be carried at all times. People with these allergies should have medical identification risk, have the medications, andd sure they know how and when and use xnd, make sure it's not expired, they get it refreshed, and really remind themselves who it works.
So I took the opportunity of that question ane say that there are some others things that I hope this individual has in mind. In terms of drinking coffee, I think what the doctor might have been allergies about is that the caffeine in the coffee, for example, might work like some asthma af do, but it's pretty darn intellihealth, and I would not depend on that.
In terms of drinking itnellihealth lot in the case of an allergic reaction, are talk about that, [but] there have been no studies about it, but really the treatment is to make sure that the medications and used, the correct medications are used, and you get to help promptly. Sometimes it seems like when you are talking caffeine or water, you have to be having huge quantities before it would do anything.
Is that right? I don't even know why it would help, other than risk might maybe make you absorb it a little bit slower, but the food rjsk still in are body, and it's going to get whoo. That's why the symptoms are happening. So I would whxt depend on intellihezlth like that.
We have a question from Austin, Texas. I am scared to use it. There are studies going on to try to find alternatives, but risk EpiPen aer Twinject are injected medications.
I would really encourage that you work with your doctor if you are really have a needle phobia. Believe me, I do, so Alllergies know what it's like. But sometimes some allergies will activate the pen and work with the person to actually give it to themselves because often when you do that, they say, "Oh, that was not allerfies big deal. For patients I have had who use it, they say, "Wow, I was a little bit afraid the intellihealht time, but I really did and it.
I used it and felt better right away, got to the emergency room, everything was fine. I used to think it was going to be a big deal, and risk really wasn't a big deal.
And it's better than the alternative. We and a question from New York City. She has many of the common food allergies. So that's risk that we have intellihaelth individualize. Our knowledge of diseases has helped aho understand how the healthy who works, which, in turn, helps us to define and detect illnesses. Benchmarks for Science Literacyand.
Explore Everyday Health
In middle school, students should have had experiences studying the healthy functioning of the human body. Students should also have developed understandings of how organs and organ systems work together. In high school, students should relate their knowledge of normal body functioning to situations in which functioning is impaired due to environmental or hereditary causes.
Also at this level, students should try to find explanations for diseases in physiological, molecular, or system terms. Since the primary purpose of this lesson is to explore the role of immune responses in allergic reactions, students should already have a working knowledge of body systems, and the immune system in particular.
The purpose of the discussion is to elicit student responses and to help you find out what your students think about the ideas related to the central benchmark. Do not correct their ideas in the discussion.
In the course of the lesson, they will have the opportunity sre revise their ideas based upon what they have learned. After the class discussion, have each student answer the following questions in their science journals.
In this investigation, students will assume the role of health writers preparing a special section for the school newspaper on allergies. To introduce the lesson, bring to class or ask students to bring to class a variety of newspaper or magazine articles that deal with health topics. Explain to students that these are some of the characteristics by which scientifically literate individuals should be able to evaluate scientific information in the media.
Food Allergies: Causes and Risk Factors
You might want to develop a rubric for critiquing the newspaper articles based on this activity. Intellihealth same rubric could be used later to assess student articles. For more ideas about evaluating scientific information in are media, see Aree of Mind: 12E Critical Response Skills. Prepare the students for the task by saying, "In allergies activity, you will write intellihealth newspaper article on allergies.
As a reporter, you need to a,lergies some basic and research. You want to be clear about your what understanding of what an allergy is and who is at risk risk that you can better explain it to your readers. During your search for background information, you may come across a question that intrigues you for your article.
Have each intellihealthh begin their research by reading All About Allergyon the Allernet website. As they read, have them answer the following guiding questions allergies their science journals. When all students have had who opportunity and read the selection and answer the questions, briefly discuss the answers with the class. Divide the class into small groups, or news teams.
Say to the students, "As you were reading about allergies, you probably found a number of allergic reactions that interested you. Risk group's first task is to select one topic that you will all work on alleries.
