How pets give your kids a brain boost - BBC

Choosing a pet starts with understanding how they fit into the home. Kelly Oakes explores what happens when animals join a family – and their profound impact on children's development.

Pick up a book from a young child's bookshelf and you're more likely to find an animal protagonist than a human one. From very hungry caterpillars to great big humpback whales, children seem universally fascinated by animals. But while characters in a picture book are often far removed from reality, the pets many of us share a home with offer children a more realistic glimpse of the animal world – and a meaningful relationship that influences them in a whole host of other ways, too.

Understanding that relationship may not only help parents choose the right pet for their child, but also give them deeper insights into the factors that make for a truly successful bond.

For many people, pets are much-loved family members who provide support across many stages of life. They can help couples to cement their relationship, act as playmates for young children, and provide companionship for parents when children leave home. One study in the US found that 63% of households with a baby under 12 months old had a pet, and an Australian study found a 10% increase in pet ownership around the time the children start school.

Many parents intuitively feel that looking after an animal can offer children valuable lessons about caregiving, responsibility and empathy. "It's really important, especially for young kids, to learn that someone's perspective might be different from their own," says Megan Mueller, associate professor of human-animal interaction at Tufts University, US. "That's an easier lesson to learn, perhaps, with an animal than it is with, say, a sibling or a peer."

But claims about the beneficial impacts of pets on children go further, suggesting that pets can influence children's social skills, physical health, and even cognitive development, and that keeping them is associated with higher levels of empathy. For children with autism and their families, pet care may help reduce stress and create opportunities to form supportive bonds.

Other research shows that children gain from animals in-the-moment, too. In one pair of studies, children made fewer errors on an object categorisation task and needed fewer prompts in a memory task when there was a dog in the room. Research has even found that, for adults at least, the simple act of viewing our pets as family members improves our wellbeing – though headlines touting the wide-ranging benefits of pet ownership are not without criticism, since people often believe that their pets improve their health and happiness, even when objective measures don't show any difference.

Interacting with pets – and with other people

So, are pets truly at the root of all these benefits, or do we just think they are? Hayley Christian, associate professor at the School of Population and Global Health at the University of Western Australia in Perth, is one of the researchers attempting to unravel cause from effect.

Using data from a longitudinal study of 4,000 children at ages five and seven, Christian and colleagues discovered that pet ownership was associated with fewer peer problems and more prosocial behaviour. In separate research they found that children aged 2 to 5 with a family dog were more active, spent less time on screens, and slept more on average, than those without a pet.

Crucially, it was the dog-facilitated physical activity – such as going on family dog walks – that made the difference.

Then, in a study published last year, they put these two pieces of the puzzle together. After controlling for factors such as socio-economic status, the researchers saw that children who regularly engaged in dog-related physical activity had better developmental outcomes.

"We can actually say that children having pets and interacting with them over time in early childhood does seem to cause these added benefits in terms of their social-emotional development," says Christian, who is also a senior research fellow at the Telethon Kids Institute.

That's not to say that every family should get a pet – or every child with a dog is better off than those without. Behavioural issues, complex medical needs and the financial burden of caring for an animal can all make life with a pet less than rosy. Families living in housing that is not pet-friendly face further barriers. "I don't think we're ever going to get to the point where we recommend that everyone with a kid gets a dog," says Mueller.

In fact, Mueller looked into whether the mental health of US teenagers with pets was better than their non pet-owning counterparts during the Covid-19 pandemic – and found that the animals appeared to make no difference. "My hypothesis is that Covid was a huge stressor and there probably isn't one thing that's enough to overcome it," she says.

It's also possible that the pandemic put a stop to one of the ways in which living with a dog can give us a boost. "We get the social benefits from interacting with the dog, but there's also this way in which animals can facilitate social interaction with other people," says Mueller. During lockdowns, teenagers might have stuck to their daily dog walks but avoided conversations with other dog walkers, losing out on small moments of social interaction.

Building a strong relationship

When it comes to the positive influence of pets on children, the state of their relationship is key – not just living under the same roof. "Relationship quality seems to be a better predictor of some of these health outcomes than just whether or not you have a pet in the home," says Mueller.

Time spent with a pet is one factor. If your sibling has a hamster that lives in their room, you're unlikely to feel very attached to it, for example, compared to a family dog that you walk every day after school.

A child's age can also help determine how solid their relationship with a particular pet becomes. Children aged between six and 10 develop stronger bonds with animals that are more similar to humans, like cats and dogs, than with biologically far-removed species like birds and fish. But older children, aged between 11 and 14, report being just as attached to less closely-related species – including mice – as they are to their dogs or cats.

Family dynamics also play a part. The Australian longitudinal study saw that children without siblings can especially benefit from pets – perhaps because they sometimes act as a surrogate sibling. "Parents are more likely to allow their child to be independently mobile [for example, run an errand alone] if they went with a sibling or a friend," says Christian. "And guess what else? A dog."

Babies in households with a pet are better at recognising animal faces by the time they are 10 months old, research shows

Pets can even aid social interactions within households. In foster families, research suggests a pet can help facilitate close relationships between foster carers and children, as well as providing companionship in its own right.

When children get to know their pets, it opens them up to a deeper understanding of animals in the wider world. "They tend to learn from their pet, somehow, how to be more understanding, empathetic and responsive to animals in general," says John Bradshaw, former reader in companion animal behaviour at the University of Bristol, UK, and author of several books on cats and dogs.

One study in the UK found that children who had pets at home were more likely to have higher levels of belief about animals' minds, that is, thinking that animals have thoughts and feelings of their own.

"You can have all sorts of imaginary stories in your head about a lion, but until somebody takes you to Africa, you'll never meet one in the wild," he says. "But a dog or a cat is there and can teach you about what it's actually like to be an animal, that animals are not human, they have very special lives that belong to them and not to us."

Even young babies are watching and learning about the animals they live with. Research by Karinna Hurley and Lisa Oakes at the University of California, Davis, US, found that infants in households with a pet were better at recognising animal faces by the time they were 10 months old than those without.

What's more, a child's relationship with their pet could provide a much-needed link with nature. "To have a real living, breathing, slightly messy animal running around the house is a good way of making those connections," says Bradshaw.

What do animals think of kids?

Remembering our pets' wild origins can give us an insight into how they see our families.

Dogs evolved to live alongside humans and have the potential to form very strong bonds with us. Cats, on the other hand, are solitary creatures at heart. Even so, they do seem to regard their human housemates as family. "Our cats greet us by raising their tails and rubbing around our legs – precisely what they do when meeting another cat they know well or consider a family member," writes Bradshaw in his book, The Animals Among Us.

But whether this kinship translates to children depends on a pet's own early life experiences.

Both cats and dogs have a brief window – for puppies this is between around eight and 16 weeks of age – where they learn about the sorts of people they might encounter in their lives. "We know that if puppies or kittens have not met children at all by the time they get to six months or so – depending on their underlying temperament – they can display really quite adverse reactions," says Bradshaw. "That suggests that they don't really recognise children as human, unless they've been introduced to them as part of the humanity package."

This makes perfect sense when you look at it from the animal's point of view, he says: "A baby is nothing like an adult human. It's much smaller, it can't stand up, it makes very different noises to an adult human, and it smells very different to an adult human."

Children rank pets as some of the most important beings in their lives – but pets can take time to get used to kids

Understanding how a pet sees the world is vital to making sure everyone gets along. If a cat urinates on a new cot or pram brought into the house, it's easy to jump to conclusions. "If you were not sympathetic to the way the cat thinks you might think, 'Oh, the cat's just getting cross because I'm going to have a baby, it must know'," says Bradshaw. "Of course, they don't know. It's very often the olfactory environment [the smell of the home] that's been churned up and the cat's lost its familiar points of reference."

Both cats and dogs rely heavily on their noses, so having lots of new smells in the house is like "coming home and finding that someone has painted your walls completely opposite colours," says Bradshaw. On the flip side, familiar scents can keep them happy. In one trial, Bradshaw and his colleagues put a t-shirt that had been worn by a dog's owner into their bed. "That familiar smell seemed to work wonders for the dog, they were much more relaxed," he says.

Not anthropomorphising our pets – meaning, expecting them to think and behave like humans – is especially important when it comes to a child's safety. "You can never be 100% sure how a dog is going to react in any one given situation," says Bradshaw. "There's all sorts of possible things which can trigger the dog into a different mode of behaviour, maybe one that the owner has never seen before."

Ultimately, each child-pet relationship is unique, with its own quirks, benefits, and pitfalls – and in some ways researchers are only just starting to understand what makes a child's relationship with their pet mutually beneficial. "The field is really moving towards looking at these more individual differences," says Mueller.

Meanwhile, children themselves rank pets as some of the most important beings in their lives, seeing their animal companions as a comfort and emotional support, as well as being infallible confidantes for a secret. Some of those benefits "are very difficult to quantify because they're very individual, and science deals in populations and big numbers," says Bradshaw. "Just because it's not very tangible and easily measured, it doesn't mean it's not real."

How dangerous is tongue-tie? - BBC

Awareness of tongue-tie, and its hidden impact on children's health, is rising around the world. Here's how it can be spotted and fixed.

By Kamala Thiagarajan

13th April 2022


Purna Parmar had been looking forward to breastfeeding her son, Janav, after his birth in 2011. But whenever he latched on to her breast, she felt a searing pain. Soon, her nipples were sore, raw and bleeding. "I found it excruciatingly painful," says Parmar, a customer care executive in Mumbai, India. "And yet, I was wracked by guilt that I couldn't even do this basic thing for my child."

Everyone around her was dismissive of the problem, suggesting it was natural for new mothers to face some breastfeeding issues. Her pediatrician suggested she switch to formula. Instead, she put up with the pain and kept up with the feeding routine as best as she could. But as time passed, Parmar realised something was wrong. At parties, her son could never play with the other kids, because he was always the last to finish his meal. At home, mealtimes were draining. Janav lingered over his food, taking up to two hours to finish.

"At first, I thought he was a sluggish eater," says Parmar. "Even his walking was slow and unsteady. And he just couldn't balance on a bike." Rushing him only created more stress. Eventually, she pureed his meals, as he couldn't chew and swallow most foods. He was constantly exhausted.

In 2019, when Janav was eight years old, the mystery was finally solved: he was diagnosed with a severe case of ankyloglossia, also known as tongue-tie, a genetic condition now gaining attention from medical experts and families around the world.

In babies born with tongue-tie, the thin strip of tissue that connects the underside of the tongue to the mouth is unusually tight. This means that instead of resting on the roof of the mouth, the tongue is tied to the floor of the mouth, which can prevent the babies from feeding properly.

The condition is thought to be genetic, and has been known for millennia, but can be hard to diagnose. In the United States, about 8% of children under one-year-old suffer from it, according to a review published in 2020.

In some countries, tongue-tie cases have increased 10-fold

Experts say that awareness of it has been rising around the world in recent years, and some countries have seen a more than 10-fold increase in diagnosed cases. In the US, both the number of tongue-tie diagnoses, and tongue-tie surgeries, have soared.

However, there are still families like Parmar's suffering through years of pain and stress caused by undiagnosed tongue-tie. In developing countries like India, healthcare providers may focus on fighting more immediate threats to babies' health, such as infections, and as a consequence, leave tongue-tie unnoticed and untreated for years. Even in countries where the condition is more frequently diagnosed, it can be overlooked.

Some years ago, Kate Canavan, a mother-of-two living in Raleigh, North Carolina, noticed her younger daughter Anna's speech was not very clear. Anna was only two years old at the time, Canavan had not had any breastfeeding issues, and her pediatrician told her not to worry about it. It wasn't until Anna was four that another pediatrician said something could be amiss and referred them to a speech therapist.

"The speech therapist told us that she had a lip-and-tongue-tie and if those weren't addressed, the speech therapy really wouldn't be very effective because her mouth anatomy was limiting her articulation," says Canavan, meaning, her daughter couldn't move her lips and tongue freely enough to speak clearly.

Trapped

The first signs of tongue-tie can be problems and pain during breastfeeding, as in the case of Parmar and her baby son.

"Children with tongue-tie can't extend their tongues beyond the tip of their lips. This results in ineffective latching, sucking and swallowing, all actions that are so essential for breastfeeding," says Ju-Lee Oei, a senior neonatologist at the Royal Hospital for Women in Randwick, Australia.

As the baby tries to move the trapped tongue and clamps down on the breast to try and feed, the result can be extremely painful for the mother.

For others, like Canavan's daughter, the problems emerge later.

"Many children with tongue-tie will not have symptoms," says Amulya K Saxena, a consultant pediatric surgeon at Chelsea Children's Hospital, Chelsea and Westminster Foundation Trust and president of the European Association of Pediatric Surgeons, in an interview over email.

The tethering of the tongue itself can be hard to spot. The lingual frenulum is a strip of tissue extending from the back of the mouth to the midline of the tongue. If this tissue is restrictive, the tip of the tongue can't extend beyond the lips, the tongue-tie can be quite evident. However, there is a more hidden kind of tongue tie, located deeper in the mouth, which requires a health professional to detect and diagnose, Saxena says.

Children living with tongue-tie may find it hard to use their tongue freely, be it to play a wind instrument, lick their lips or an ice cream, or use their tongue to help clean their teeth during the day. "In some children, it may cause cuts under the tongue if the lingual frenulum gets trapped between the lower incisor teeth," Saxena says.

The tongue's awkward position, and weaker tongue muscle as a result of the lack of movement, can cause problems beyond the mouth.

"One of the biggest issues with tongue-tie is that the air-pressure balance in the mouth is affected, and this can cause nasal breathing that disrupts sleep," says Ankita Shah, a pediatric dentist and director of the Tongue Tie and Sleep Institute in Mumbai, who diagnosed Parmar's son's case.

Children with tongue-tie often contend with open-mouth breathing and snoring, she says, which affects the quality of their sleep. They wake up frequently with a congested nose, and tend to clench or grind their teeth while asleep, leading to neck and shoulder stiffness, and headaches. The constant discomfort, even if quite subtle, can affect their posture and overall wellbeing.

"We don't realise how much the alignment of the teeth, tongue and the jaw can influence an entire range of body functions," says Shah.

A quick fix?

In milder cases, the problem may resolve itself, says Saxena, the London-based surgeon. The connecting strip stretches as the baby feeds and moves her tongue, and over time, the tongue is less restricted. Advice on the right breastfeeding technique, massaging the frenulum, and exercising the tongue can all help resolve such mild cases, in his view. But if that doesn't work, or if the tongue-tie makes breastfeeding very difficult, he recommends the release procedure. This involves a small cut into the frenulum to help release the tongue.

However, all of these problems – struggling with feeding, eating, breathing, sleeping and speaking – can have other causes. And while in countries like India tongue-tie may be under-diagnosed, some doctors in other countries see a risk of over-diagnosing it.

We went from 10 cases of tongue-tie a month, to 10 per week - Ju-Lee Oei

"In 2017, when we had a huge surge in cases, we decided to look into it," says Oei. The Royal Hospital for Women in Randwick, Australia, where she works, records 4,500 births on average each year. Until that year, they usually had only 10 requests for tongue-tie surgery every month. "We went from 10 a month, to 10 cases per week," says Oei.

Cases at other hospitals in the area had risen too, and some practitioners were charging steep rates for the procedure. "We realised that the surgery was in high demand because it was seen as a quick-fix to correct breastfeeding troubles. However, cutting the frenulum to release the tongue doesn't magically solve all problems," she says.  

The results of their global study, published in 2018, noted that the diagnosis of tongue-tie had risen more than 10-fold in some countries, varied considerably around the world and that greater efforts to standardise care were needed.

Since then, the guidelines at their hospital have changed, says Oei. Every child struggling to breastfeed because of suspected tongue-tie must now be assessed by a breastfeeding consultant. Surgery is recommended only after two-to-four weeks of trying to solve the breastfeeding issues with the consultant's support.

As Oei and her colleagues note in their research paper, even the relatively simple surgery used for tongue-tie should not be carried out lightly, as "subjecting infants to a surgical procedure, no matter how minor, causes pain, stress, possibly longer-term neurological harm".

Surgery and 'tongue yoga'

Saxena, the pediatric surgeon in London, has noticed that families are growing more aware of tongue-tie. "Patient support groups and professional bodies are now offering information on social media," she says.

In India, Shah has also observed a rise in the number of families seeking help, including those with older children. But she, too, advises against resorting to surgery too quickly.

Out of 10 patients who walk into her clinic, roughly only half will need surgery, says Shah. It depends on the severity of the tongue-tie, and its impact on the body, including the airways. "We evaluate the varying symptoms each patient has with this condition, and we ask ourselves if the problem is only because of the tongue-tie? We try to correct other associated problems first before opting for surgery."

While older children may need general anaesthesia, cases in younger children tend to be treated with local anaesthesia, Shah says. In the case of newborns, anaesthesia isn't used at all, as the risks would outweigh the benefits.

However, surgery is not the end of the treatment, says Carmelle Gentle, an independent midwife and breastfeeding consultant based in London. Gentle, who has set up a donation-based tongue-tie centre in South London, recommends that parents help the baby use and strengthen their tongue after the snip, through various exercises.

"We support babies to use their tongue in a new way," she says. "It's a bit like yoga. You may not be able to touch your toes at the beginning of the session, but regular, gentle practice helps you get there."

I was just so relieved that there was a name for what we were going through – Purna Parmar

For some, the growing awareness – and right diagnosis – can be life-changing.

Kate Canavan's daughter, Anna, was helped by surgery. "Because her frenulum was so thick and muscular, and she was so young, the speech therapist and an [ear, nose and throat specialist] recommended that the procedure be done with a surgical scissors and under general anaesthesia. That way, they would be careful to not damage surrounding tissue while releasing the tongue," says Canavan over email.

After the 15-minute procedure, Anna didn't need any pain medication and was able to eat and drink without any problems. She even went to pre-school the next day. Within a month of surgery, her speech improved dramatically.

Purna Parmar in Mumbai, whose son had suffered from tongue-tie for so many years, burst into tears when her doctor told her about the condition: "I was just so relieved that there was a name for what we were going through."

It then took her two years to convince her family that an operation was necessary, but it was worth it, she says. He had the surgery, and it helped. Today, Janav enjoys experimenting with different foods, can finish his meal in 20 minutes – and is then off to ride his bike.

Boy or girl? It's in the father's genes

A study of hundreds of years of family trees suggests a man's genes play a role in him having sons or daughters. Men inherit a tendency to have more sons or more daughters from their parents. This means that a man with many brothers is more likely to have sons, while a man with many sisters is more likely to have daughters.

FULL STORY

A Newcastle University study involving thousands of families is helping prospective parents work out whether they are likely to have sons or daughters.
The work by Corry Gellatly, a research scientist at the university, has shown that men inherit a tendency to have more sons or more daughters from their parents. This means that a man with many brothers is more likely to have sons, while a man with many sisters is more likely to have daughters.
The research involved a study of 927 family trees containing information on 556,387 people from North America and Europe going back to 1600.
"The family tree study showed that whether you’re likely to have a boy or a girl is inherited. We now know that men are more likely to have sons if they have more brothers but are more likely to have daughters if they have more sisters. However, in women, you just can’t predict it," Mr Gellatly explains.
Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother’s X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother’s to make a boy (XY).
The Newcastle University study suggests that an as-yet undiscovered gene controls whether a man’s sperm contains more X or more Y chromosomes, which affects the sex of his children. On a larger scale, the number of men with more X sperm compared to the number of men with more Y sperm affects the sex ratio of children born each year.
Sons or daughters?
A gene consists of two parts, known as alleles, one inherited from each parent. In his paper, Mr Gellatly demonstrates that it is likely men carry two different types of allele, which results in three possible combinations in a gene that controls the ratio of X and Y sperm;
  • Men with the first combination, known as mm, produce more Y sperm and have more sons.
  • The second, known as mf, produce a roughly equal number of X and Y sperm and have an approximately equal number of sons and daughters.
  • The third, known as ff produce more X sperm and have more daughters.
“The gene that is passed on from both parents, which causes some men to have more sons and some to have more daughters, may explain why we see the number of men and women roughly balanced in a population. If there are too many males in the population, for example, females will more easily find a mate, so men who have more daughters will pass on more of their genes, causing more females to be born in later generations,” says Newcastle University researcher Mr Gellatly.
More boys born after the wars
In many of the countries that fought in the World Wars, there was a sudden increase in the number of boys born afterwards. The year after World War I ended, an extra two boys were born for every 100 girls in the UK, compared to the year before the war started. The gene, which Mr Gellatly has described in his research, could explain why this happened.
As the odds were in favour of men with more sons seeing a son return from the war, those sons were more likely to father boys themselves because they inherited that tendency from their fathers. In contrast, men with more daughters may have lost their only sons in the war and those sons would have been more likely to father girls. This would explain why the men that survived the war were more likely to have male children, which resulted in the boy-baby boom.
In most countries, for as long as records have been kept, more boys than girls have been born. In the UK and US, for example, there are currently about 105 males born for every 100 females.
It is well-documented that more males die in childhood and before they are old enough to have children. So in the same way that the gene may cause more boys to be born after wars, it may also cause more boys to be born each year.
How does the gene work?
The trees (above) illustrate how the gene works. It is a simplified example, in which men either have only sons, only daughters, or equal numbers of each, though in reality it is less clear cut. It shows that although the gene has no effect in females, they also carry the gene and pass it to their children.
In the first family tree (A) the grandfather is mm, so all his children are male. He only passes on the m allele, so his children are more likely to have the mm combination of alleles themselves. As a result, those sons may also have only sons (as shown). The grandsons have the mf combination of alleles, because they inherited an m from their father and an f from their mother. As a result, they have an equal number of sons and daughters (the great grandchildren).
In the second tree (B) the grandfather is ff, so all his children are female, they have the ff combination of alleles because their father and mother were both ff. One of the female children has her own children with a male who has the mm combination of alleles. That male determines the sex of the children, so the grandchildren are all male. The grandsons have the mf combination of alleles, because they inherited an m from their father and f from their mother. As a result, they have an equal number of sons and daughters (the great-grandchildren).

Stop putting your kids' food in plastic containers: Top pediatricians tell parents to use glass or steel packaging to lower kids' exposure to chemicals

  • The American Academy of Pediatrics has warned that chemicals in processed meat and plastic is more dangerous to kids than parents may think
  • They call for an update to the guidelines allowing 1,000 chemicals in food and containers
  • They also warn that, while high-income groups can afford to make substitutes, many low-income families will struggle to avoid these chemicals 

A panel of top pediatricians is urging parents to cut out as many chemicals from their child's packed lunch as possible.
Cans, plastic containers, and processed meats are just a few of the culprits they singled out as classic carriers of toxins that can get into a child's blood system and affect their hormones - potentially impacting development.
Things like BPA (which makes plastic hard) and nitrates (which make food last longer) have been part of everyday life for decades, and the traces are often so scant that they are 'generally recognized as safe'.
But the new policy statement, which will be published in the August edition of the journal Pediatrics, warns we now have significant evidence about the dangers of even tiny amounts of these toxins - and yet, the authors believe many parents remain blasé about the risks.
They also warn that low-income communities and ethnic minorities tend to be exposed to higher concentrations of these chemicals - a disparity that is not widely addressed in mainstream medicine. 
Risky? Cans, plastic containers, and processed meats are just a few of the culprits that the American Academy of Pediatrics singled out as classic carriers of toxins that can get into a child's blood system and affect their hormones - potentially impacting development

Our current guidelines on chemicals in food are laid out in the 1958 Amendment to the 1938 Federal Food, Drug, and Cosmetic Act (FFDCA). 
It allows for about 1,000 chemicals to slip into our food and containers, because they are deemed GRAS (or, 'generally recognized as safe'). 
But, the authors say that 'accumulating evidence from nonhuman laboratory and human epidemiological studies' is showing that the threshold may not be low enough - particularly to protect children from the damage.
The report comes on the heels of a spate of studies warning about the extent to which we are exposed to these chemicals. 
Most of them have focused on pregnant women's exposure, and how that affects their unborn babies. 
Dr Janice Juraska of the University of Illinois last month told Daily Mail Online she was 'shocked' by her latest study, published on July 16, showing that women who eat food from plastic containers are more likely to have kids with slower reactions. The difference, she said, was stark.  
A week later, a study by the University of California, San Francisco found most pregnant women have high levels of at least 50 chemicals - such as BPA, triclosan and parabens - in their blood. 
With each report, chemists and endocrinologists warn that exposure to these chemicals in the womb could be life-changing for these women's kids. 
But this new advisory from the American Academy of Pediatrics reminds the public that kids of all ages are still going through a crucial phase of development, and they caution that evidence suggests our kids would be better off in the long run if we reduced their exposure to these chemicals as much as possible. 
WHAT ARE THE CHEMICALS TO LOOK OUT FOR? 
  • Phthalates, chemicals used to make plastic flexible and fragrances last longer 
  • BPA, chemicals used to make plastic containers harder 
  • PFCs, used in greaseproof paper and cardboard
  • Perchlorate, used in plastic food packaging
  • Nitrates, used to preserve food and maintain its color, particularly in processed meats 
HOW CAN YOU AVOID THEM?
The authors concede that avoiding these chemicals can be hard - particularly for low-income families. 
Toxin-free materials, like steel containers or reusable glass bottles, tend to be more expensive. Fresh, organic food free of preservatives is also pricey, since low-income areas tend to have fewer fresh food markets per square mile.   
For those communities, they urge pediatricians to 'advocate for modernization of the FFDCA', to force all sectors of food and product manufacturing to lower their levels of these chemicals.   
For those that can, they recommend taking these steps: 
  • 'Prioritize consumption of fresh or frozen fruits and vegetables when possible, and support that effort by developing a list of low-cost sources for fresh fruits and vegetables.
  • 'Avoid processed meats, especially maternal consumption during pregnancy.
  • 'Avoid microwaving food or beverages (including infant formula and pumped human milk) in plastic, if possible.
  • 'Avoid placing plastics in the dishwasher.
  • 'Use alternatives to plastic, such as glass or stainless steel, when possible.
  • 'Look at the recycling code on the bottom of products to find the plastic type, and avoid plastics with recycling codes 3 (phthalates), 6 (styrene), and 7 (bisphenols) unless plastics are labeled as 'biobased' or 'greenware,' indicating that they are made from corn and do not contain bisphenols.
  • 'Encourage hand-washing before handling foods and/or drinks, and wash all fruits and vegetables that cannot be peeled.'
