Transcript for Dr. Richard Besser Breaks Down New Baby Peanut Allergy Guidelines
This is Dan Charles with the ABC news medical unit and now welcome to the world is FaceBook page. I'll talk about something a lot of parents or interest at an and that is allergies specifically peanut allergies. Now the national institute of allergy and infectious disease came out with a set of guidelines today that should help guide parents. In terms of what to do about peanuts because it's something that a lot of parents are very concerned about. I hear is our doctor Richard that's our chief health and medical editor I can't also pediatrician to tell us more about this arms so just to get started. What do these recommendations. Represent. What. Because this is really Robert a you know it pediatrician poorer. It's almost thirty years and this flies in the face of everything I learned as a PS progress in terms of how you keep kids who were at risk of it used to be if the child who is at higher risk for an hour news Peter out here any other. You would say to a parent don't give them that group that first year and it differs two years of life. To try to reduce their exposure and hopefully prevent him to go. But a study came out in two Ingrid 2015. Turned everything upside down. And Whitney with a look at ways. Whether early introduction. Can teach kids who were at higher risk appear. Would reduce the chances that it Keyes would development Canada and the reason they did this that he was was pretty incredible. Team that there was an observation me. Jewish kids in the UK. Had about ten times hiring. RG then children seem ancestral background living in Israel. At what they recognize was in Israel they gave it subpoena Earl and in the UK they waited for years. And so the idea was maybe do something about this practice that led to so. They did this study with the cowboys. Children were higher risks of these were kids who that case in which is in dry skin condition. Or were already allergic. Get this group of children. If they even peanut girl it reduced the chances by seventy to 85%. That they wouldn't. Eight unit out. And it was Michael and so the question was close Wednesday. Wouldn't that medical community rally program and changed when they wanted to do. So that in the national institutes of hell. Pulled together and be a committee experts for from around the country many different disciplines of allergy and dermatology. They came together they reviewed the evidence and they came out Uga sides that now say. Early is better for its its amazed. So it's all of these art got justice now. Preventing kids with priorities from getting in contact now there's a whole other dimension yet so if you look at statistics. Back in nineteen and about. Point 4% of children hear us. Fast forward ten years whose opted to present its high end. As a pediatrician. When you see a child he's got to hear. There is this sense of the year around this all the time that parents are absolutely. Paralyzed they're frightened. When their child leaves their site they're going to be exposed that to penis. It doesn't happen often but it. Reactions to food are the leading cause of food related deaths that they don't happen frequently repeated as the number one. It's so that's all we hear about peanuts on planes and units and schools and penis and cafeteria. And hoping is that with these new guidelines. In ten years fifteen years. We're gonna reach the point whenever they the number of kids who are allergic to peanuts as declines so much. Did people can can relax this doesn't change it for people who are dealers and but the idea that you can prevent this both in terms of cycle cost. It's it's really got us right. So seems like there's something here not only for parents. Who have kids who outlook allergies to certain things his anger out at eczema but also for parents who. I have kids who are necessarily allergic to anything but they worry that any money yet. When their eighties that namely the they might powdery action that's or. So in this in knee these islands the great children and ended three groups got one group of kids. Where Cyrus group and so these are children who early on have severe eczema. Oh or allergy those children recommendations says should be tested. To see if they are ready sensitized. To Kenya and there's a let cast in the skin testing. The initial tests may be done by some pediatricians and then kids who referred her to specialists. The next group of children children who have mild or moderate. Dry skin condition. And then the third group of kids are kids who don't have any skin reactions are all the high risk group. Any recommendations that they get he introduced ages four to six months. If dedicated to reaction to two. Unit is this that he should be given a doctor's office under observation. But the other groups it doesn't happen via can be gotten all the kids who have mild 86 months. And they they provide some guidance you don't wanna give a look at Acuna want to make sure that people get that message. -- itself is here from booty it is really really dangerous. Here department to looting peanut butter one more committee and nice soft material that you give us. In his should be given. But you're an occasion no. Sensitivity aren't you can start you know whenever you would normally wouldn't. I think you win when you start being chosen candidate for six months can it can be one of those who do get pretty pivotal point that they don't recommend you as the first food. Give enough beavers just seeing it and happier peach. Right right and I think veterans really looking forward to three hours from now when you movies and discussing this on world news yeah well we can't figure out this. It's been making headlines around the country today. And we're going to be going into that today all you need to know about this rumors from. And well one thing. You know question I think that caused people's minds because remember. As it always used to bring you arsenic is to me was like one of my favorite things that never. Wednesday you never see is the consummate his Kryptonite to what extent. Do you think that these guidelines. Are going to change this situation they they won't change anything in the near term. Because we're talking about prevention so you got a group of children report this year they'll be in school and another five years but they're still children there who who card risk. I would expect an and it takes a long time for things changed in terms of policy. You wanna see that the percentage of children with Canada he goes yeah. So that's a 2% now you probably want to get it back down below 1% before you went into any change. So I don't know how quickly that will change but it you if you think about. Just reducing the number of families who were affected by she. The impact of this is is an epic. Right price and you know one of the things that stuck out about the guidelines. Is if you happen it doesn't have any evidence of any Condit allergies. And says okay you can just go added whenever you want to use our injuries peanut containing food. Let's say I'm a parent who's really nervous. Thinking all I don't know I want it you know necessary it is what ideas disorders. I guess allay those fears and and he because this this this concern as a pediatrician I spindle. Lot of time talking to the parents McGrath is happy because. It's a hard thing now you know baby start you know preferably breast milk or formula. There on that report is six months and then you're starting south streets. We used you really dogmatic guy you'd OK the first period you spew rice cereal and no court breast milk or formula that to diluted out. Then after that you can go to make cereal there today vegetable that he noticed. All of those things that we and our our peace who they're basically wrong now it's basically. In of these foods based on what families to eat. You know you don't mind is whether lucrative time to lose her reaction. Clinton all of this dogma past done this way turns out to be wrong. But I spent a lifetime talk McAlester oh what do UTE. And you'll need parents from different cultural backgrounds who weaker U proves it's OK well we want to get your child. Accustomed to the guy that you like you as is possible so if your family is it is. Is not Stanley that is big into eat beef. We're back on top editors being you know what. That it takes place the and so it's it's very tailored way and I would say to parents were thinking about this taught here your pediatrician doctor your child's doctor doubted that your comfortable. On how you're gonna introduce. Pete or or other clues. I think that this is gonna lead to further research program not just peanuts other food allergies because their kids ruler. Your tree nuts all kinds of different foods. And if this principle works for Pina. It strikes me is that is lately it worker other types of food we could see food she's. Right will be. August. Great questions coming in on. A FaceBook. There's a lot of people are ordering them. I knew there are still skeptical. They pulled one thing. And now they're wondering why should the leaflets being told them yet there and I think skepticism is is a good thing. You know before yeah if I came from an allergic pale I would want to sit down my doctorate go through this gripping tale. And come up with a plan around this thing. But it didn't nature of science and what we do is that you do studies and you learn. And if what you learn flies in the face what you do before. You look at that you really hard I wanna replicate studies and and and make sure that one thing isn't it now wire and that report. And for some people it's a difficult things and what did he say copies good when basic copies bat. This is a little different from that the study being viewed wood is incredibly. Well. It's what we call randomized trial so he didn't just look at oak some kids their parents give peanuts and so did the sign to. Happy group to get into early half not two as and he followed them for five years to skew it happened and it was a dramatic. Difference between two groups. But you want to talk to your doctor Peter if you're not Koppel asked for another opinion. Asked to see specialists if you're apparently were where you've suffered from the effects of severe reaction subpoena me sure you can count who is important you go toward. Well thank you so much once again is going to be on world news this evening 630 with a hero really looking organized and our investor thank you so long it's a pleasure. CO it.
