• 0:05
  Speaker 1: Today's podcast, we're diving into the latest research and talking
• 0:08
  Speaker 1: about what can help us as parents to raise happier families.
• 0:11
  Speaker 1: But I am doctor Justin Coulson and who with my
• 0:13
  Speaker 1: wife and mum to our six kids, missus happy families.
• 0:17
  Speaker 1: Kylie Coulson Kylie three studies. Today we're going to talk
• 0:19
  Speaker 1: about peanut algies. We're talking about social media screens because
• 0:24
  Speaker 1: it's just the enduring, never ending conversation if you're a
• 0:27
  Speaker 1: parent of a child. And also a really fascinating study
• 0:29
  Speaker 1: that I wanted to share for our neurodivergent friends, Autism
• 0:32
  Speaker 1: and Touch, a new study out of Italy looking at
• 0:34
  Speaker 1: how touch affects those who are neurodivergent with an autism
• 0:38
  Speaker 1: diagnosis versus those who are neurotypical no diagnosis at all.
• 0:42
  Speaker 1: Let's dive into it.
• 0:44
  Speaker 2: It's interesting when I think about my upbringing, I don't
• 0:47
  Speaker 2: remember ever hearing about a peanut allergy. Neither do I
• 0:52
  Speaker 2: didn't exist. Yeah, yeah, yeah, everyone to a peanut butter.
• 0:54
  Speaker 2: We had to tell her, Like you just I'd never
• 0:57
  Speaker 2: heard of it. And yet in today's world, it feels
• 1:01
  Speaker 2: like every second kid is allergic to something and it's
• 1:05
  Speaker 2: altered what our kids can even put in their lunchboxes.
• 1:08
  Speaker 1: Okay, So an important note as we have this conversation.
• 1:10
  Speaker 1: I mean, some schools are completely peanut free. There are
• 1:13
  Speaker 1: bands all over the place. We're going to talk about
• 1:15
  Speaker 1: a psychological intervention, but I want to be really clear,
• 1:17
  Speaker 1: if your child has a peanut allergy, please follow the
• 1:19
  Speaker 1: medical advice of your practitioner. We're speaking about an intervention
• 1:23
  Speaker 1: and some research. We're not giving advice when it comes
• 1:25
  Speaker 1: to your child and peanuts.
• 1:27
  Speaker 2: So what did they actually find?
• 1:29
  Speaker 1: Let me give you the I'm not going to bury
• 1:31
  Speaker 1: the lead here. It is right now peanut allergies could
• 1:33
  Speaker 1: drop by seventy one percent with a brand new intervention
• 1:36
  Speaker 1: developed by some researchers at King's College in London.
• 1:41
  Speaker 2: Seventy one percent. That's huge.
• 1:42
  Speaker 1: Yeah, yeah, yeah, So the intervention feeding kids peanuts, I know,
• 1:48
  Speaker 1: I know.
• 1:49
  Speaker 2: Can I just say it's interesting when we hear about
• 1:53
  Speaker 2: whether it's a peanut allergy or you know, someone's been
• 1:58
  Speaker 2: heard in a car accident, or it changes the way
• 2:01
  Speaker 2: we live.
• 2:02
  Speaker 1: Life, right, so you have it become really risk averse.
• 2:05
  Speaker 2: Yeah, you hear that there's peanut allergies and all of
• 2:07
  Speaker 2: a sudden, all the peanuts get banned, right, or there's
• 2:09
  Speaker 2: a car accident down this particular road, Well that's an
• 2:12
  Speaker 2: unsafe road to travel on. We just we go so
• 2:16
  Speaker 2: polar extreme and this research studies suggesting that that may
• 2:20
  Speaker 2: be the case.
• 2:21
  Speaker 1: Yeah, here's what they did. What they basically said was
• 2:23
  Speaker 1: feed kids peanuts regularly from four months of age to
• 2:26
  Speaker 1: five years, and they're less likely to show up with
• 2:29
  Speaker 1: the with the allergy. Now, I need to note very
• 2:33
  Speaker 1: clearly when they're saying feed kids peanuts regularly from four months,
• 2:38
  Speaker 1: they're not saying give your four month old a peanut.
• 2:42
  Speaker 1: That would be potentially life altering, it could be catastrophic.
• 2:46
  Speaker 1: What they're saying is peanuts and peanut products. So consider
• 2:49
  Speaker 1: the developmental appropriateness of handing your child a peanut. If
• 2:52
  Speaker 1: they're too young to be able to chew, bite, swallow
• 2:55
  Speaker 1: a peanut, give them peanut paste, give them peanut butter,
• 2:58
  Speaker 1: give them some other nut oriented product, the things that
• 3:03
  Speaker 1: contain things that they're okay. And as they get older
• 3:07
  Speaker 1: and can suddenly and can chew those nuts, that's when
• 3:11
  Speaker 1: you start to give them the full monty, the whole nut. Basically,
• 3:15
  Speaker 1: what they found this is fascinating. This method works even
• 3:18
  Speaker 1: if your child never eats another peanut after the age
• 3:21
  Speaker 1: of five. I love this. So if you can get
• 3:24
  Speaker 1: your kid exposed to nuts in those first five years
• 3:27
  Speaker 1: and you don't have any reactions, which typically you won't
• 3:32
  Speaker 1: after the age of five, they made decide I don't
• 3:34
  Speaker 1: like peanuts, I never want to eat another nut again,
• 3:37
  Speaker 1: and they'll still be okay.
• 3:39
  Speaker 2: So how did they actually figure this out?
• 3:40
  Speaker 1: Okay? Professor Gideon Lack is a King's College, London research
• 3:44
  Speaker 1: He published this research of the New England Journal of
• 3:45
  Speaker 1: Medicine and what he found basically is avoiding so old.
• 3:49
  Speaker 1: The old story was avoid nuts. As you said, avoidance
• 3:52
  Speaker 1: is necessary. What he found in his study was that
• 3:55
  Speaker 1: avoiding nuts increases the risk of allergy. Doesn't reduce the risk.
• 3:58
  Speaker 1: It increases the risk of allergy. They had six hundred
• 4:00
  Speaker 1: and forty participants. They gave half of them nuts during
• 4:03
  Speaker 1: the first five years of their life. They gave the
• 4:06
  Speaker 1: other half nut all that Sorry, they didn't give the
• 4:08
  Speaker 1: kids nuts. They instructed parents to either give or not
• 4:10
  Speaker 1: give their children peanuts, and then they tested them at
• 4:13
  Speaker 1: age five to see if they had the allergy. There
• 4:15
  Speaker 1: was an eighty one percent reduced risk of allergy in
• 4:17
  Speaker 1: the nut group versus the no nut group. What's fascinating
• 4:21
  Speaker 1: to me though, is that they followed up at the
• 4:23
  Speaker 1: age of thirteen, So from this point on there's no
• 4:26
  Speaker 1: direction given whatsoever about whether you should or should not
• 4:28
  Speaker 1: eat nuts. Fifteen point four percent fifteen and a half
• 4:32
  Speaker 1: percent of those people who were avoided nuts in those
• 4:35
  Speaker 1: first five years were allergic to nuts. Wow, whereas only
• 4:40
  Speaker 1: four point four percent of nut eaters were allergic. So
• 4:45
  Speaker 1: to be clear, feeding your child nuts in the first
• 4:47
  Speaker 1: five years does not absolutely guarantee they will not have
• 4:50
  Speaker 1: the nut allergy, but it reduces the likelihood of the
• 4:53
  Speaker 1: peanut allergy by seventy one percent. That's huge, It's enormous.
• 4:58
  Speaker 1: So that's our study Number one, Feed your kids nuts.
• 5:01
  Speaker 1: Nuts are good.
• 5:02
  Speaker 2: I couldn't imagine living life without nuts. Get into nuts.
• 5:13
  Speaker 1: All right. Study number two, Social Media Use and the
• 5:17
  Speaker 1: Mental Health of Children and Adolescents.
• 5:20
  Speaker 2: I feel like every doctor's desk has a social media
• 5:24
  Speaker 2: or screen aspect to it. What's different about this study.
• 5:28
  Speaker 1: This is a smart study. It's been preregistered. There's a
• 5:31
  Speaker 1: control group who lives life as normal, and then there's
• 5:34
  Speaker 1: an intervention group in the intervention group. We've got one
• 5:38
  Speaker 1: hundred and eighty one children and adolescents in a Danish
• 5:41
  Speaker 1: study and their job is to do a two week
• 5:45
  Speaker 1: screen media reduction intervention. Okay, so basically the children and
• 5:50
  Speaker 1: adolescents hand in their smartphones and their tablets and they're
• 5:53
  Speaker 1: not allowed more than three hours of screens per week
• 5:58
  Speaker 1: per person.
• 5:59
  Speaker 2: You know that, and that just sounds like bliss it honest, you.
• 6:04
  Speaker 1: Were the most fluttered away. As you said it, your
• 6:05
  Speaker 1: eyes started to flutter and you're like, ah, so would
• 6:10
  Speaker 1: you like me to tell you what they found? Of course,
• 6:12
  Speaker 1: of course, fewer emotional symptoms. That is, children were better regulated.
• 6:17
  Speaker 1: There was less disregulation in the intervention group compared to
• 6:21
  Speaker 1: the control group.
• 6:22
  Speaker 2: I kind of want to say, d I know, I
• 6:24
  Speaker 2: really like this is it's so obvious.
• 6:28
  Speaker 1: Fewer peer problems. In other words, the children were just
• 6:31
  Speaker 1: better at social stuff and I won't say it again,
• 6:35
  Speaker 1: and more pro social behavior. Ah, kids are nice to
• 6:40
  Speaker 1: each other and they manage their emotions better when they
• 6:43
  Speaker 1: don't have as much access to screen.
• 6:46
  Speaker 2: Is amazing. I feel like we got a really huge
• 6:50
  Speaker 2: sense of this during COVID when everything shut down and
• 6:53
  Speaker 2: we just were able to kind of really tap into
• 6:57
  Speaker 2: family life together.
• 6:58
  Speaker 1: Well, some people did, but when the other direction and
• 7:01
  Speaker 1: screens became their lives, especially around schooling right, and some
• 7:05
  Speaker 1: people said this is killing us, got to get off
• 7:07
  Speaker 1: the screens. Whereas as you said, for us, we were
• 7:10
  Speaker 1: really conscious of bringing it down.
• 7:13
  Speaker 2: So what's your take on this?
• 7:15
  Speaker 1: My take, in a nutshell, Mike Zuckerberg and his colleagues
• 7:19
  Speaker 1: are colleagues. That's just far too polite a word for
• 7:21
  Speaker 1: who they are and what they are. Are responsible for
• 7:25
  Speaker 1: more unhappiness in our young people, and on a larger
• 7:29
  Speaker 1: scale than perhaps anyone else in human history. That's my take.
• 7:34
  Speaker 1: I absolutely cannot comprehend the pure mendacity, the deceitfulness, and
• 7:42
  Speaker 1: their ongoing manipulation of our families and our children and
• 7:45
  Speaker 1: young people's lives in search of attention economy dollars. They
• 7:50
  Speaker 1: are just absolutely, absolutely disgraceful. I blame the system, I
• 7:56
  Speaker 1: blame the politicians, But because nothing is happening unfortun as parents,
• 8:00
  Speaker 1: it lands on us, and if we're not doing something
• 8:03
  Speaker 1: about it, we are also unfortunately responsible. I was at
• 8:09
  Speaker 1: an event just the other day. I was giving a
• 8:11
  Speaker 1: talk and somebody told me that they're seven year olds
• 8:13
  Speaker 1: on Snapchat. Why because they're big brothers and sisters are
• 8:15
  Speaker 1: on Snapchat, And I just said no, Like, as a parent,
• 8:19
  Speaker 1: you've got a responsibility. Get your seven year old off Snapchat.
• 8:22
  Speaker 1: They don't need to be on roadblocks, they don't need
• 8:24
  Speaker 1: to be on Minecraft. More and more evidence is coming
• 8:27
  Speaker 1: out telling us that we at the very least need
• 8:29
  Speaker 1: to be breathtakingly cautious. But I think when you look
• 8:32
  Speaker 1: at a study like this one out of Denmark, we're
• 8:34
  Speaker 1: seeing really clearly. Just get the kids outside, get them
• 8:39
  Speaker 1: being physically active, have them involved in play, especially risky play,
• 8:43
  Speaker 1: and get them involved with other people. Children outside, not
• 8:47
  Speaker 1: in the house, not with a screen. They're going to
• 8:49
  Speaker 1: be so much better off, better emotionally regulated, more physically capable,
• 8:54
  Speaker 1: and they're also going to be more pro social as
• 8:56
  Speaker 1: a general rule.
• 8:57
  Speaker 2: Well, I'm going to lower your blood pressure because I
• 8:59
  Speaker 2: feel like it's our last study. We're talking about autism
• 9:03
  Speaker 2: and touch. This is quite intriguing.
• 9:07
  Speaker 1: Yeah, so most people, most people do better with touch.
• 9:10
  Speaker 1: We had a Doctor's Desk episode where we talked about
• 9:12
  Speaker 1: the importance of touch. You got very excited in that one.
• 9:15
  Speaker 1: You got because if you're neurotypical and you get touched
• 9:18
  Speaker 1: as so long as it's consensual and it's the kind
• 9:21
  Speaker 1: of touch that you would like, Oh gosh, it just
• 9:23
  Speaker 1: feels good. Right. Italian researchers have looked at the difference
• 9:27
  Speaker 1: between neurotypical responses to touch and neurodivergent responses to touch
• 9:32
  Speaker 1: with people who are diagnosed.
• 9:34
  Speaker 2: Autistic and what did they find?
• 9:36
  Speaker 1: In a nutshell, lower physiological responses to touch, but higher
• 9:40
  Speaker 1: ratings for both pleasant and unpleasant touch. So, in other words,
• 9:44
  Speaker 1: it's really complicated. There's a lot of sensory issues around this,
• 9:48
  Speaker 1: and I think we probably need to dig deeper, especially
• 9:50
  Speaker 1: for any parent of an autistic child, or maybe maybe
• 9:53
  Speaker 1: even for any autistic parents who listen to the pod,
• 9:55
  Speaker 1: this will probably resonate and there'll be a few ah
• 10:00
  Speaker 1: kind of moments.
• 10:01
  Speaker 2: So why does touch actually matter?
• 10:03
  Speaker 1: Okay, so touch matters. We did discuss this briefly in
• 10:07
  Speaker 1: that last podcast, but let's talk about it. Number one,
• 10:10
  Speaker 1: it's really important to help establish and maintain relationships before
• 10:13
  Speaker 1: verbal skills have developed. Okay, so when you've got a
• 10:15
  Speaker 1: brand new baby, it's all about touch. Crucial role in
• 10:18
  Speaker 1: human communication, crucial role in social interaction, and it conveys
• 10:22
  Speaker 1: so much emotional and social meaning that promotes attachment, social affiliation, bonding,
• 10:30
  Speaker 1: and we know, especially if touch is consensual and it's
• 10:35
  Speaker 1: the kind of touch that somebody wants, there are really
• 10:38
  Speaker 1: pleasant effects like we feel we just feel really.
• 10:41
  Speaker 2: Good about that.
• 10:42
  Speaker 1: The question about autism though not particularly well answered, and
• 10:47
  Speaker 1: this study helps us to answer it.
• 10:49
  Speaker 2: So what did they do in the study?
• 10:51
  Speaker 1: Yeah, forty eight participants, twenty four with ASD and twenty
• 10:54
  Speaker 1: four typically developing controls participants.
• 10:57
  Speaker 2: With they it's quite a small group.
• 11:00
  Speaker 1: Yeah, it is twenty four inch, but that's enough. That
• 11:03
  Speaker 1: is enough for us to get something meaningful here. Essentially,
• 11:05
  Speaker 1: participants they sat down, put their left arm on a table.
• 11:08
  Speaker 1: It was hidden from view by wooden panel so they
• 11:11
  Speaker 1: couldn't see it, and then each participant was touched on
• 11:15
  Speaker 1: their left forearm different types of touch. There was what's
• 11:19
  Speaker 1: called affective touch, which is slow gentle strokes and controlling
• 11:25
  Speaker 1: kinds of touch. So that was lots of tapping. That's
• 11:28
  Speaker 1: how you would characterize it, just tap tap, tap, tap tap.
• 11:31
  Speaker 1: So I'm in kind of annoying and not at all
• 11:34
  Speaker 1: like the affective slow gentle strokes. The experimenter delivered the
• 11:41
  Speaker 1: held I say, the experimental delivered the touch stimuli and record.
• 11:45
  Speaker 1: They had it all set up so they could record
• 11:47
  Speaker 1: the physiological responses of the participant using a device that
• 11:50
  Speaker 1: measured skin conductance, which is a pretty good way of
• 11:53
  Speaker 1: identifying whether or not there's any autonomic nervous system activity.
• 11:58
  Speaker 1: And in addition to having that skin conductance recorded, each
• 12:01
  Speaker 1: participant also rated the touch on how pleasant or unpleasant
• 12:05
  Speaker 1: it was, just using a numerical scale, so pretty basic,
• 12:08
  Speaker 1: really flexible. Allows participants to applause if they don't like it,
• 12:13
  Speaker 1: if they're overwhelmed, if they're feeling fatigued, and that kind
• 12:15
  Speaker 1: of thing.
• 12:16
  Speaker 2: And what was the outcome of the study?
• 12:18
  Speaker 1: In a nutshell, individuals with ASD showed lower overall skin
• 12:24
  Speaker 1: conductance compared to neurotypical participants, which means that there's a
• 12:29
  Speaker 1: lower autonomic response. And this is where I think it
• 12:33
  Speaker 1: gets really interesting. Well, typically developing participants had a higher
• 12:36
  Speaker 1: physiological response to affective touch compared to the controlling tapping touch.
• 12:43
  Speaker 1: That wasn't shown in the ASD group. In other words,
• 12:46
  Speaker 1: people with ASD did not show a distinct autonomic response
• 12:52
  Speaker 1: to the two different kinds of touch. It was basically,
• 12:56
  Speaker 1: you're touching me, full stop end, Sorry, you're touching me. Yes,
• 12:59
  Speaker 1: there is difference, but you are touching me. Whereas neurotypical
• 13:02
  Speaker 1: people were like, I like that one, I don't like
• 13:04
  Speaker 1: that one. Here's something really interesting though, despite the lack
• 13:09
  Speaker 1: of that physiological differentiation, individuals with ASD rated both the
• 13:16
  Speaker 1: affective and the control touch higher than typically developing participants
• 13:24
  Speaker 1: by our neurotypical participants, which means that they subjectively are
• 13:29
  Speaker 1: experiencing the touch more intensely on both the positive and
• 13:32
  Speaker 1: the negative scale. I think this is fascinating to look
• 13:34
  Speaker 1: at and it highlights.
• 13:36
  Speaker 2: But not at a physiological level like this is.
• 13:39
  Speaker 1: It's really curious, isn't it. So if you're a parent
• 13:41
  Speaker 1: of an autistic kid, I think what I would be
• 13:44
  Speaker 1: saying really is do you like it when I touch you?
• 13:48
  Speaker 1: How do you like to be touched? I think that
• 13:51
  Speaker 1: it just requires exploration with an acknowledgment that touch can
• 13:55
  Speaker 1: for a child who has any kind of sensory issues,
• 13:58
  Speaker 1: It can be overwhelming and frustrating and just too much.
• 14:03
  Speaker 1: So again, my main emphasis based on what this study
• 14:06
  Speaker 1: is showing is consent. Consent and conversation around touch are
• 14:11
  Speaker 1: going to be your best friends.
• 14:14
  Speaker 2: So three big studies today, we've talked about how to
• 14:17
  Speaker 2: lower our kids possibility of having a nut allergy by
• 14:21
  Speaker 2: actually exposing them to it from as four months.
• 14:24
  Speaker 1: Early as we just don't give them whole nuts at
• 14:26
  Speaker 1: four months.
• 14:27
  Speaker 2: Please, reducing screen use with our families is going to
• 14:34
  Speaker 2: deeply enhance.
• 14:36
  Speaker 1: We're going to have better kids, your.
• 14:39
  Speaker 2: Family connections and everything else that goes with it, right
• 14:42
  Speaker 2: and autistic children in touch.
• 14:44
  Speaker 1: This is a really intriguing I'm so glad that you
• 14:47
  Speaker 1: enjoyed our doctor's desk you normally complain about it, looks
• 14:49
  Speaker 1: like you actually got something out of this one. Each
• 14:52
  Speaker 1: of these studies will be linked in the show notes
