One Piece of Advice to Parents Slashed Food Allergies in Children

One Piece of Advice to Parents Slashed Food Allergies in Children

Yahooa day ago
New research highlights a crucial time window very early on in life, during which the introduction of eggs and peanut butter into the diets of babies significantly reduces the chances of them becoming allergic to these foods later on.
The findings run counter to previous advice given to parents to avoid giving these foods to their kids until they're at least a year old over concerns that they might trigger allergic reactions.
Here, researchers led by a team from the University of Western Australia compared the experiences of two groups of children in Australia: 506 whose parents got no specific feeding advice, and 566 whose parents were advised to start adding eggs and peanut butter to the diets of the infants at around six months.

"For the babies in group two – whose caregivers followed the updated guidelines and introduced peanut butter and egg around six months of age – egg allergy reduced from 12 percent to 3 percent, and peanut allergy reduced from around 6 percent to 1 percent," says Summer Walker, a health scientist at the University of Western Australia.
In other words, earlier introduction of these foods at the six-month mark made a notable difference to the number of kids who went on to develop allergies by 12 months of age. Cow's milk was also included, though here the difference was smaller.
The advice itself isn't new, and the six-month milestone has in fact now been added to the official Infant Feeding and Allergy Prevention Guidelines proposed by the Australasian Society of Clinical Immunology and Allergy (ASCIA). Testing the guidelines in real population groups confirms the recommendations are safe and effective.
The parents of the second group of 566 were provided with hard copies of the ASCIA guidelines, and the researchers are keen to raise awareness of the latest expert advice on how best to reduce allergy risk.
"By increasing the distribution of guidelines and encouraging health professionals to share the information, we can considerably reduce the incidence of food allergies in the community," says Walker.
Understanding why allergies develop is a complex challenge, and it's important to note that these infants were only tested for allergies up to 12 months – and that allergies to peanut butter and eggs weren't completely eradicated.
Nonetheless, amid signs that food allergies in children have been on the rise in spite of instructions to avoid specific food items, a review of the relationship between diet and immune responses is critical.
This is just one part of the picture, but it's strong evidence that the latest guidelines do make a difference – even in relation to a higher level of genetic risk. All the babies involved in the research had a close relative with an allergy to one of these foods, and allergies often run in families.
"Some parents are still confused about when to introduce allergens – especially those families with a history of allergies," says research dietitian Debbie Palmer, from the University of Western Australia.
The research has been published in the Journal of Allergy and Clinical Immunology: In Practice.

Fresh support for ‘ham sandwich' ad ban

A leading health body has thrown its full support behind South Australia's controversial move to ban junk food ads on public transport assets, saying it's time to 'draw a line in the sand' and protect Aussie kids from unhealthy marketing. Food for Health Alliance executive manager Jane Martin, in a statement released to NewsWire, said the ban, which is now in effect, would influence diets and help pull down the 'wallpaper' of junk food ads. 'Current food marketing rules in Australia are largely voluntary and controlled by industry itself,' she said. 'They're ineffective, inconsistent and full of loopholes. 'As a result, junk food ads bombard kids everywhere they go – on social media, on billboards, on public transport, at sports games. 'It is the wallpaper in our children's lives and it shapes what kids want, what they pester their parents for and, ultimately, what they eat.' The ban prohibits a range of junk food items from being displayed on Adelaide's buses, trains and trams, including processed meats like ham. Chocolate, lollies, confectionary, desserts, ice creams, soft drinks and chips are all banned from display alongside processed meats, with the measure designed to limit children's exposure to unhealthy food and drink advertising. The ban ignited controversy in the months before its July 1 introduction, with the Australian Association of National Advertisers pushing hard against what it called a 'blanket ban'. 'As it stands, this policy bans all processed meats, which means a simple ham salad sandwich can't be advertised.' AANA chief executive Josh Faulks said in May. 'This simply doesn't make sense and the government should be making evidence-based decisions, not blanket bans that don't align with nutritional science.' The AANA confirmed with NewsWire it opposed all advertising bans for food and beverages. Health Minister Chris Picton, speaking in May, said the AANA was 'scaremongering' and 'providing misinformation about this commonsense policy'. 'It is not up to advertising industry lobbyists to tell us what can be displayed on our public transport assets,' he said. Some 63 per cent of adults and 35 per cent of children across South Australia are overweight or obese, government figures show. On Tuesday, Ms Martin said the government had made a 'smart and necessary step' that was backed by evidence. 'After similar restrictions were introduced by Transport for London, expected household purchases of unhealthy food and drinks dropped by more than 1000 calories per week,' she said. 'Other cities like Canberra, Amsterdam and New York have also adopted similar policies. 'The processed food and advertising industries have had a long, profitable run. 'But now it's time we draw a line and stop letting them promote their unhealthy products to kids on their daily commute.' She warned Australia was already lagging behind international best practice in protecting children from 'unhealthy food marketing'. 'Our kids are paying the price,' she said. 'Over a third of Australian children's daily energy intake now comes from unhealthy food and drinks, more than 40 per cent for teenagers. 'Unhealthy diets are placing children at higher risk of being above a healthy weight in adulthood and from developing type 2 diabetes, stroke, heart disease or 13 cancers later in life.'

Renewed calls to make major driver's licence change for older Aussies: 'We have to'

The discussion of whether older Australians should be subject to additional driver's licence requirements has been reignited following a fatal car accident involving a 91-year-old driver. Authorities in Victoria are looking to review the road rules after a two-year-old boy was hospitalised and two adults, thought to be his grandparents, died after they were hit while walking on a suburban street in Melbourne last week. The elderly woman behind the wheel at the tragedy in the Melbourne suburb of Wantirna South last Thursday was "terribly shaken", police said. She was taken to hospital with minor injuries and has yet to be interviewed by police. The morning after the incident, Victoria's Acting Premier Ben Carroll renewed the discussion on driving regulations for the elderly and confirmed he would work with the road safety minister on the matter. Road safety advocates across the country have since weighed in on the debate, with Russell White, founder of the Australian Road Safety Foundation, arguing the latest incident should be the catalyst for standardised change across the country. "Sadly, it's taken someone to have a serious incident and for lives to be lost for us to have discussions like this," he told Yahoo News. "We have to try and look at how we become more proactive in this space and take some probably hard decisions to alter what people's view is on driving." Victoria does not have age-based driving safety requirements, although drivers aged 75 and older must renew their licence every three years, which can involve various tests. In NSW, Queensland, the ACT, Tasmania and the Northern Territory, drivers older than 75 are required to have a health check, while older drivers in South Australia must complete self-assessments. In Western Australia, an annual medical assessment is required to renew a driver's licence after turning 80. White believes all drivers need more rigorous training over the years after they acquire their licence. "In an ideal world, I would like to see some form of additional coaching that happens," he said. It could come with a practical driving evaluation once a decade, he suggested. While he believes that it may be unpopular to implement such a framework, saving lives is the ultimate priority. "We've got to look at standardising the framework for older drivers, including lifelong learning as far as coaching is concerned," he said. Startling statistics released in the past year reveal elderly drivers are disproportionately represented in road crash statistics. Older drivers aged 85 and up are disproportionately affected by fatal crashes, according to data by Road Safety Education Limited (RSE) earlier this year, while insurance company AAMI singled out senior Australians as risky drivers in their Decade of Driving report. Following the incident, Dr Anita Muñoz, Victorian chair of the Royal Australian College of General Practitioners, argued that age is not an innate barrier to safe driving and people of all ages must recognise their responsibility when it comes to being a safe driver. "Fitness to drive and safety on the road is, however, something we should all be proactive about — for ourselves, with our family members, and as GPs, with our patients," she said. "There's an association between our health and our social connectedness and mobility, so it's valuable for older people to continue to drive, but only for as long as it is safe. "Proactive discussions about safety on the road are part of what we as GPs discuss with older patients, but it's something you should think about too, for yourself and others in your life." Ben Rogers, CEO of Council on the Ageing (COTA) Victoria, which represents the interests of older Australians, cautioned against licensing requirements, arguing that Victoria leads the country in how it approaches the issue by focusing on "ability rather than age". "We don't want to see any sort of legislation change in Victoria, but we are happy to have the conversation about mandatory testing for all drivers," he told Yahoo. "It's incumbent on all of us on the roads to make sure that we are driving safely. "Driving is a privilege, no matter whether you're 45 or 75, if you are not fit to drive you shouldn't be on the roads." He believes family, friends, and medical practitioners should be supporting conversations with drivers about their fitness to drive across all age groups and ensuring that subsidised additional training is available for those who wish to partake in it. Investigations into the exact circumstances surrounding the collision at Wantirna South remain ongoing, Victoria Police confirmed. — With AAP Do you have a story tip?
