What do economics have to do with health? At most universities they’re not even in the same building! But it turns out that a dip in the economy can lead to a rise in our weight according to a study done by John Hopkins. Researchers found that from 2008 to 2012—the period known as the great recession—weight gain was strongly correlated with the rise in unemployment, increasing the risk of obesity by 21 percent. This makes sense as one of the first things to go when our budgets get tight are luxuries like health food and gym memberships, not to mention the loss of health insurance that often accompanies a job loss. However, it may help to remember that there are many low-cost or free ways to protect your health—and an investment in you is the best one you can make.
How high you are
No we’re not talking about the wave of pot legalization sweeping the country (although that probably would affect your weight too) but rather how high up you live. There’s a reason that Colorado is the both the slimmest and the steepest state in the nation. The altitude at which you live is strongly correlated with your weight, with each gain in altitude corresponding with a drop in weight, according to a study done by the U.S. Air Force. But don’t sell your beach-front property and head for the hills just yet—the effect can be balanced out by other factors known to prevent against obesity where you live, like outdoor greenery, strong social ties, and opportunities to go outside. Case in point: Hawaii is the third thinnest state in America, and it’s the definition of sea level.
It’s a generation thing
Ever wondered why your grandma never exercised a day in her life and yet wore a tiny wedding dress that you could never hope to fit into even though you run marathons? Some of it may be due to the difference in generations you were both born into. Bad news for young ‘uns: Millennials, Gen Y, and Gen X all need to eat less and exercise more to stave off obesity than their forefathers did, according to a study from York University. And it’s not just the fact that we have Netflix and take out at our fingertips. Rather, the researchers found that the average metabolism of both men and women has slowed, even after controlling for factors like disease, diet, and fitness. Why? We have no solid answers yet but in the meantime, if you’re under 40 at least you can take comfort that you’re not alone in your struggle.
That cursed smog
The effects of environmental pollutants go far beyond wheezing and sneezing. Rats exposed to highly polluted air were not only much more likely to become obese, according to a study done by Duke University, but also had a greater risk of heart disease, diabetes, and metabolic syndrome. And it’s not just limited to rodents. People who live close to roadways with a high level of air pollution are also more likely to gain weight, says a study from the University of Southern California. Unfortunately air pollution is likely not under your direct control but we can all work together to lobby for and implement clean-air policies where we live, making for both a healthier physical and celestial body.
Your thermostat
Our delightfully warm and cozy homes and offices might be partly responsible for our less-delightful expanding waistlines, say researchers in a study published in the journal Cell. The scientists found that regular exposure to mildly cold weather—as would have been normal in the days before programmable thermostats—helps the human body regulate a healthy weight. The chilly air seems to increase metabolism by making the body work harder to cope with the changing conditions. Some proponents of “cold therapy” take daily ice baths or “shiver walks” but you don’t have to be that extreme to see results, say the researchers. Just lowering your thermostat by a few degrees or turning the shower briefly to cold can help.
How many antibiotics you’ve taken
Antibiotics are one of the biggest miracles of modern medicine, no doubt about it. But those infection-fighting drugs may have unintended consequences. The more antibiotics a person takes during their lifetime, particularly during early childhood, the greater their risk of becoming obese, according to an NYU study. Researchers speculate that it has to do with killing healthy gut bacteria, decimating your microbiome along with the bad bugs, as good bacteria has been shown to help prevent weight gain. But if you were the kid with chronic ear infections, don’t fret, you can rebuild your good gut bacteria by taking a probiotic and eating plenty of fermented foods such as yogurt, kefir, sauerkraut, and kimchi.
Fido and Fifi
Owning a pet, particularly a dog, slashes the human companion’s risk of obesity, says the American Heart Association. Why? Dogs need to be walked daily and are often quite persistent, encouraging their owners to walk as well. But it’s not just the extra exercise, especially since 40 percent of dog owners confess to not walking their dog on a regular basis. The researchers add that petting an animal greatly reduces stress and depression, two other known risk factors for weight gain. So if you do have a dog, make sure to walk them daily, and in the meantime soak up all the snuggles, wet kisses, and purrs you can.
The number on your paycheck
Income is one of the biggest factors correlated with obesity, with poor Americans being three times more likely to be obese than richer ones, according to a study published in Nutrition Reviews. Low-income people are less likely to have access to supermarkets with fresh foods (often living in “food deserts”), less likely to have health insurance, and less likely to live in neighborhoods where exercise outdoors is encouraged or even safe. Fortunately this is one area we can all help improve by working to better conditions in our own neighborhoods or helping out others nearby.
Pesticides
Pesticides may help us grow stronger and more plentiful crops but many of the chemicals used in popular formulations are known “endocrine disruptors”: They interfere with your body’s metabolic systems. Pesticides hijack our metabolism by mimicking, blocking, or otherwise interfering with the body’s natural hormones, according to a report issued by The Endocrine Society. Regular exposure to pesticides through food was correlated with an increase risk of both obesity and diabetes. Buying all organic may be one solution but for many people that doesn’t fit in the budget. If money’s tight you can also decrease your pesticide load by avoiding, or only buying organic of, the “dirty dozen“, the most contaminated produce. Or you can always try growing some of your own fruits and vegetables. (Bonus: Gardening is great exercise!)
How many trees you can count from your window
Close proximity to parks, trails, and other types of green spaces is linked with lower body weight, according to research done by the American Diabetes Association. Being able to see, and more importantly walk to, greenery encouraged people to exercise more and made it feel, well, less like exercise. Parks make physical exertion feel like fun but even if you’re not using them to exercise, simply being in the presence of nature has been shown to reduce stress, lower weight and improve your health overall. The vast majority of Americans already live within walking distance of some type of park so get out there and explore your neighborhood.
All that stuff on the food label you don’t recognize
You already know that processed foods do no favors for your waistline but it turns out it’s not just the empty calories and trans fats doing the damage. Some of the most popular food additives are linked with weight gain and obesity, according to a study done by Georgia State University. Emulsifiers, which are added to most processed foods for texture and to extend shelf life, are one of the worst offenders as they interfere with good gut bacteria. But some artificial flavorings, artificial sweeteners, preservatives, and even the food packaging have also been linked in research to obesity.
Chocolate is dangerous for dogs — but that risk is highest at Christmas.
A study in the BMJ’s special Vet Edition warns of a “significant peak” in the risk of chocolate poisoning in dogs over the holidays.
Chocolate contains a chemical called theobromine, a stimulant similar to caffeine. Humans can handle it, but it’s nasty stuff for our four-legged friends. It can cause vomiting, diarrhea, increased heart rate and even seizures.
“Humans process it very quickly, so we can eat chocolate with gay abandon,” P-J Noble, a veterinarian at the Small Animal Teaching Hospital in Liverpool, U.K., and one of the authors of the study, told CBC’s Kas Roussy.
“In dogs, they don’t get rid of it very quickly. It hangs around and builds up to toxic levels very easily.”
Dogs face special dietary health risk during holidays
Researchers have known for some time that chocolate and dogs don’t mix. But Noble and his team wanted to find out whether dog exposure to chocolate was tied to any of the big holidays — Christmas, Easter, Valentine’s Day or Halloween.
After reviewing millions of electronic health records from 500 vet clinics in the U.K., they found Christmas beat them all when it came to chocolate exposure.
Santa Claus figurines, Advent calendars, and Christmas tree decorations made of chocolate were high on the doggy list of favourites.
But who can blame Fido for sticking his snout where it doesn’t belong? Dogs like sugar, and when it’s on display it’s hard to resist.
One particular furry friend likely made Santa’s naughty list. The study reports that the dog had ingested six Toblerones and six Terry’s Chocolate Oranges.
“I would feel ill after that,” says Noble.
None of the more than 300 cases of chocolate poisoning reported in this study was considered life-threatening, but too much of a good thing can be bad. When ingested in large amounts, chocolate can be fatal for dogs, especially if it’s of the darker variety, Noble said.
So, Merry Christmas to all, say Noble and his colleagues, “but keep the chocolate away from your dog. Because no one wants to be going to the vet on Christmas Day.”
It seems unconditional love from a fluffy, drooling canine is one key to a healthier life — as many people already expected.
A study of more than 3.4-million people revealed that having a dog in the house is linked to living a longer life. The research, published in Scientific Reports by Uppsala University in Sweden, reviewed a national registry of people aged 40 to 80 for up to 12 years. Just over 13 per cent were dog owners.
By evaluating health records, it found that registered dog owners had a lower risk of having heart attacks and other life-threatening conditions. It said owning a dog cuts down the risk of death from cardiovascular disease by 36 per cent for people that live alone.
There is a slightly lower benefit to owning a canine for those who don’t live alone — the risk was cut by only 15 per cent. Researchers even considered other factors such as smoking and body weight to make sure the results were as accurate as possible.
While the study stops short of determining a direct “causal effect” between dog ownership and lower heart disease, it indicates that dog owners may have better health because they stay active by walking their pets, even in bad weather.
A new study says owning a dog can lower chances of developing heart problems.
It adds that having a fluffy friend could also help ease feelings of isolation, depression and stress.
“Dog ownership is associated with a lower risk of cardiovascular disease in single households and with a reduced risk of cardiovascular and all-cause death in the general population,” the study concludes.
And it’s just one of many studies that have come to a similar conclusion about the health benefits of owning a dog.
Earlier this year, a study found that seniors who own a dog spend an average of 22 more minutes per day staying active and take an additional 2,760 steps per day.
Dogs have also been found to improve mental health in children, and help soothe stress for travellers nervous about their flight and students during exams.

Parents of children struggling with eczema or asthma might think that having a dog would only make it harder to control their child’s condition.
But two new studies suggest man’s furry best friend might actually provide some protection against allergic diseases.
The first study contends that having a dog in the house before you’re even born may help keep eczema at bay at least until your toddler years. The skin disorder is marked by dry, extremely itchy patches.
“Eczema is usually the first manifestation of [allergic disease] and eczema can predict the development of other [allergic diseases] as kids grow,” said study author Dr. Gagandeep Cheema, an allergy and immunology fellow at Henry Ford Hospital in Detroit.
The researchers analyzed 782 mother-child pairs and collected data on prenatal exposure to dogs, which included days where a dog spent at least one hour inside the home.
When the investigators compared kids with prenatal dog exposure to those without, the risk of eczema was reduced in children of dog households by about half at age 2. The effect appeared to diminish by age 10, but Cheema said the researchers are still gathering data and suggested that finding might eventually change.
The second study looked at living with dogs and the odds of asthma symptoms linked to substances found on the dog, such as bacteria, or the dog’s own allergens. This study included 188 children from Baltimore with the breathing and wheezing disorder. Ninety-two percent were black, and their average age was 10.
Researchers from this study found that the non-allergen substances on the dogs appeared to reduce the need for an asthma inhaler and reduced nighttime symptoms of asthma. On the flip side, exposure to allergen-inducing proteins from dogs seemed to up the odds of inhaler use and nighttime symptoms.
“Among urban children with asthma who were allergic to dogs, spending time with a dog might be associated with two different effects,” said study author Dr. Po-Yang Tsou, from Johns Hopkins University.
“There seems to be a protective effect on asthma of non-allergen dog-associated exposures, and a harmful effect of allergen exposure. However, dog allergen exposure remains a major concern for kids who are allergic to dogs,” Tsou said in a statement.
Dr. Craig Osleeb is a pediatric allergist and immunologist at Northern Westchester Medical Center in Mount Kisco, N.Y. He reviewed both studies and said the research left a lot of questions unanswered.
Osleeb noted that the kids with higher exposure to the dog allergen proteins were the ones that tended to have more symptoms. He said isolating those proteins that caused worse symptoms might be a way to help families with asthmatic children find dogs that may help asthma rather than make it worse, though it’s too soon to tell yet.
Tsou’s study found no protective effect from exposure to cats. The research also didn’t find a benefit from exposure to other common allergens such as dust mites or cockroaches.
Cheema said it’s too soon to say whether or not people should try to increase exposure to dogs to keep allergic diseases at bay.
“I wouldn’t tell anyone to go get a dog. It can be a dangerous thing if people have severe allergies and asthma,” she noted.
But for parents who already have a dog in the home, “it’s definitely fair to say that this and other research has shown that a dog may be protective,” she added.
Cheema said the current theory is that having a dog may expose children to substances that affect their microbiome — the natural mix of bacteria found in the gut.
Both studies were to be presented Friday at the American College of Allergy, Asthma and Immunology’s annual meeting, in Boston. Findings presented at meetings are typically viewed as preliminary until they’ve been published in a peer-reviewed journal.

Around 30% of people are thought to carry the parasite often caught from a common domestic pet.
People with impulsive anger problems could have a parasite in their brain, a new study suggests.
Those who continually display behaviours like road-rage could be infected with a common parasite rather than having a psychological disorder.
Around 30% of people are thought to carry the toxoplasma gondii parasite — it is often present in, and caught from, cat faeces.
Professor Emil Coccaro, who led the research said:
“Our work suggests that latent infection with the toxoplasma gondii parasite may change brain chemistry in a fashion that increases the risk of aggressive behavior.
However, we do not know if this relationship is causal, and not everyone that tests positive for toxoplasmosis will have aggression issues.”
The conclusions come from a study of 358 adults.
The results showed that people with ‘intermittent explosive disorder’ (that’s rage issues to you and me!) were twice as likely to test positive for the toxoplasma gondii parasite in comparison to a healthy control group (22% versus 9%).
Across all the people in the study, those who tested positive for the toxoplasma gondii parasite had significantly higher levels of aggression and anger.
Dr Royce Lee, a study co-author, said:
“Correlation is not causation, and this is definitely not a sign that people should get rid of their cats.
We don’t yet understand the mechanisms involved–it could be an increased inflammatory response, direct brain modulation by the parasite, or even reverse causation where aggressive individuals tend to have more cats or eat more undercooked meat.
Our study signals the need for more research and more evidence in humans.
Professor Coccaro said:
“It will take experimental studies to see if treating a latent toxoplasmosis infection with medication reduces aggressiveness.
If we can learn more, it could provide rational to treat IED in toxoplasmosis-positive patients by first treating the latent infection.”
The study was published in the Journal of Clinical Psychiatry (Coccaro et al., 2016).

June 8, 2015 – Could a common cat parasite put people with a weakened immune system at risk for schizophrenia and other types of mental illness?
CBS News reports that new research suggests such a possible link, but doesn’t prove a cause-and-effect connection.
More than 60 million people in the United States have the Toxoplasma gondiiparasite, but most never experience any symptoms. But in people with a weakened immune system, T. gondii can cause an illness called toxoplasmosis and potentially lead to miscarriages and fetal problems in pregnant women, long-lasting flu-like illness, blindness and even death, CBS News reported.
Previous research had linked T. gondii with schiziophrenia and bipolar disorder, and two recent studies provide further possible evidence of a connection between the parasite and mental illness, the news network said.
In a paper published in the journal Schizophrenia Research, investigators analyzed three previous studies and found that exposure to cats during childhood may be a risk factor for mental disorders late in life, CBS News reported.
“Cat ownership in childhood has now been reported in three studies to be significantly more common in families in which the child is later diagnosed with schizophrenia or another serious mental illness,” E. Fuller Torrey, of the Stanley Medical Research Institute, and Dr. Robert Yolken, of Stanley Laboratory of Developmental Neurovirology at the Johns Hopkins University School of Medicine, said in a news release.
In a second paper, researchers analyzed 50 published studies and found a potential link between T. gondii and mental disorders. They saw that people infected with the parasite had a nearly two times increased risk of developing schizophrenia. The researchers also found a possible association between T. gondii and addiction and obsessive-compulsive disorders, CBS News reported.
“In schizophrenia, the evidence of an association with T. gondii is overwhelming,” A.L. Sutterland, who’s with the Department of Psychiatry at the Academic Medical Centre in Amsterdam, Holland, and colleagues said in a press release, CBS News reported. “These findings may give further clues about how T. gondii infection can possibly [alter] the risk of specific psychiatric disorders.”
Their study was published in the journal Acta Psychiatrica Scandinavica.
“Children can be protected by keeping their cat exclusively indoors and always covering the sandbox when not in use,” Torrey told CBS News in an email.
Change your cat’s litter box daily and avoid feeding cats raw or undercooked meat, the U.S. Centers for Disease Control and Prevention advises. When changing the litter box, it’s best to wear disposable gloves and wash hands thoroughly with soap and water afterwards. Pregnant women should not clean litter boxes.
