A new study backs up concerns about exposure to the chemical Bisphenol A, or BPA, from food cans and jar lids.
When thinking about our health, most of us will only consider our weight and fitness level, but our lives are made up of so much more. When you understand what is actually going on in your life, you may develop clues as to why you eat and live the way you do.
People take up running, and other types of exercise, mainly to get fit and lose weight. But there’s often a social aspect, too. After a gruelling run, some people like to retire to the pub or club house for an ice cold beer.
Something as simple as picking up a cup of tea requires an awful lot of action from your body. Your arm muscles fire to move your arm towards the cup. Your finger muscles fire to open your hand then bend your fingers around the handle.
Chronic fatigue syndrome, a condition where normal exertion leads to debilitating fatigue that isn’t alleviated by rest, has long mystified scientists. There are no known triggers, and diagnosis requires lengthy tests.
Moms who eat high-fat, high-sugar diets may be putting future generations at risk for metabolic problems, even when their offspring eat healthy diets, a new study with mice suggests.
Summer holidays are upon us, and many of us will finally get to spend some lazy days by the pool. But how can you ensure this pleasant experience doesn’t leave you with any nasty surprises?
Potent doses of broccoli sprout extract activate a “detoxification” gene and may help prevent cancer recurrence in survivors of head and neck cancer, according to new research that confirms preliminary results released last year.
Young adults who are in high-quality relationships are in better physical and mental health, a new study shows.
No one wants to serve spoiled food to their families. Conversely, consumers don’t want to throw food away unnecessarily – but we certainly do.
The estimated annual health care costs related to obesity are over $210 billion, or nearly 21 percent of annual medical spending in the United States.
Our primal mind has no defense against the stressful world it now faces, and we are paying a terrifying price for it. The toll this takes is insidious as well as profound, and it must be appreciated if steps are to be taken to mitigate its effects...
On any ranked list of nasty diseases transmitted by mosquitoes, ticks and fleas in the Western world, Borrelia burgdorferi, would have to lie near the top. These bacteria cause Lyme disease, which was first recognised in the US in the early 1970s among patients in Lyme, Connecticut.
Regular exercise in middle age is the best lifestyle change a person can make to prevent cognitive decline in their later years, a 20-year study finds.
A few years ago I proudly lost almost 15% of my weight. However last week I stared with disbelief at my scale as I realised all my efforts were in vain and I had regained all of the previously lost weight.
For thousands of years humans have defended themselves from harm by others. But many have proceeded to regularly harm themselves. They have actively searched for substances to ingest, inhale, inject and apply which may give them some immediate relief but damage or destroy their lives over time.
According to the World Health Organization (WHO), more women are affected by depression than men. This pattern is seen in countries around the world, including the United States.
In this modern age, we tend to run from the sun due to what I believe to be understandable but overblown concerns about skin cancer. Since the time of the Greeks, heliotherapy (sun therapy) has been a valuable way to heal the body and balance the mind.
Fentanyl, a synthetic opioid narcotic about 100 times as potent as morphine, continues to be in the news, as deaths from fentanyl overdose continue to rise and even more potent nonpharmaceutical forms become available on the street.
The World Health Organisation’s cancer arm made two announcements this week: one welcome and one not so welcome.
The “common cold” is common. Most of us will have at least one or two per year. Children get sick more often and very young children often get more than five colds per year.
A few years ago, I gave conferences in Montreal regarding the healing properties of natural spring water. I was fascinated by the reports of people drinking natural spring water and stating that many of their illnesses vanished or greatly improved just by drinking such water.
Scientists have uncovered a link between emotional stress and diabetes, with roots in the brain’s ability to control anxiety.
When you think about self-care, do you have visions of massages or pedicures and facials? Total self-care also includes eliminating self-criticism, not overscheduling, releasing the need to be perfect, saying no, refusing to do things out of guilt, and giving yourself much-needed...
With an estimated 100,000 health and fitness apps available on the two leading smartphone platforms, iOS and Android, it seems there is an app for everything – from tracking your bowel movements, to practising your pimple-popping technique.
It’s easy to explain the appeal of drugs like heroin and cocaine, which directly stimulate the brain’s reward centres. What’s less easy to explain is the appeal of psychedelic drugs such as LSD and psilocybin that produce altered states of consciousness.
Foods high in fat, especially saturated fat, are bad for you. A high-fat diet is a risk factor for cardiovascular disease as well as metabolic disorders like obesity and type 2 diabetes. So why does saturated fat have these effects on the body? What’s going on in your body when you eat a fatty meal?
A recent study by the National Institutes of Health found that more than one in three people in the United States have experienced pain of some sort in the previous three months. Of these, approximately 50 million suffer from chronic or severe pain.
Since the 1980s biologists have used genetic engineering to express novel traits in crop plants. Over the last 20 years, these crops have been grown on more than one billion acres in the United States and globally. Despite their rapid adoption by farmers, genetically engineered (GE) crops remain controversial among many consumers, who have sometimes found it hard to obtain accurate information.
A revolution in how we think about preventing cavities in children is upon us. Evidence shows that cavity formation has less to do with genetics, candy habits or poor brushing, and more to do with the types of snack foods we give children. Counter-intuitively, dark chocolate is better for teeth than pretzels or crackers.
Feelings are very much like the indicator lights on the dashboard of your car — if you are out of gas, the low-fuel light will turn on. If you are focusing on something unwanted, a negative feeling will show up. Your emotional state indicates what you are giving attention to, even if you are not aware of it.
I find it sad that people have to keep discovering wisdom through their own tragedies. I am saying this in the hope that you will take the time to read on, learn from the wisdom of others, and not require a disaster to become your teacher.
Have you ever wondered how freshly baked bread gets its a golden brown crust and why it smells so good? Or how nondescript green berries turn into beautiful brown coffee beans with a rich alluring aroma?
A golden era of antibiotics shifted the leading causes of death away from infection to cancer and cardiovascular disease. At the moment, we can still treat most infections as only a few are resistant to what is currently the last line of antibiotics – the colistins.
Everyone knows that Britain’s conclusive victory over Napoleon was at Waterloo. The story of that day – the squares of infantry repulsing cavalry charges, the Imperial Guard retreating under murderous musket fire delivered by a red line of soliders, the just-in-time arrival of Field Marshal Blücher’s Prussian army – is one of excitement, horror and heroism.
We know so much about the genes that cause disease, so why are we not approaching an age of Star-Trek-like medicine in which a doctor can wave a handheld device over a patient, claim to have sequenced the genes of the offending pathogen, then move rapidly to a cure?
The near panic caused by the rapid spread of the Zika virus has brought new urgency to the question of how best to control mosquitoes that transmit human diseases. Aedes aegypti mosquitoes bite people across the globe, spreading three viral diseases: dengue, chikungunya and Zika.
Last week, the National Obesity Forum caused a furore by claiming that eating fat, including saturated fat, will help cut rates of obesity and type 2 diabetes. Public Health England hit back, calling NOF’s advice “irresponsible”.
Marisa Fisher's research suggests people with Williams syndrome can learn to say no to strangers, refuting past studies that indicated sociability may be hard-wired in individuals with Williams syndrome.
Alcohol: why do we drink it? People have been consuming alcohol for at least 10,000 years. And when drinking water was rather risky, alcohol seemed a much safer bet. Amaldus of Villanova, a 14th-century monk, even wrote that alcohol “prolongs life, clears away ill humors, revives the heart and maintains youth”.
"As doctors, we throw things like antihistamines, ointments, and lotions at patients who suffer chronic itching, but if there is something profoundly abnormal about the immune system—as it appears there is—then we can't solve the itching until we address those underlying causes," says Brian S. Kim.
In the past week you’ve probably eaten crops that wouldn’t exist in nature, or that have evolved extra genes to reach freakish sizes. You’ve probably eaten “cloned” food and you may have even eaten plants whose ancestors were once deliberately blasted with radiation. And you could have bought all this without leaving the “organic” section of your local supermarket.
Despite massive government, medical and individual efforts to win the war on obesity, 71 percent of Americans are overweight. The average adult is 24 pounds heavier today than in 1960. Our growing girth adds some US$200 billion per year to our health care expenditure, amounting to a severe health crisis.
"Conflict happens in every marriage, but people deal with it in different ways. Some of us explode with anger; some of us shut down," says Claudia Haase. "Our study shows that these different emotional behaviors can predict the development of different health problems in the long run."
Many people believe eating healthily is expensive – and more costly than buying junk food. But our new research, published in the journal BMC Public Health, shows this isn’t the case.
“I have something to say. I want to share it with you.” By tapping a few keys in a specific sequence, I have made a code emerge on the screen. When you see these words, the language area of your brain (usually the left side) converts the sequence into meaning. If I have selected well, this meaning will match the message I wanted to convey.
Traditionally, someone who suffered from hypertension – or high blood pressure – would only receive treatment when his or her blood pressure was measured and the reading was found be higher than normal. But this meant that the condition was often picked up only when the person had a stroke or a heart attack – and in many instances this was too late.
It only takes a single fly to alight on your picnic lunch to make you uneasy about what germs may have landed with it. But what harm can come from a fly landing on your food? Should you throw it away?
Things happen in our lives because we believe in our subconscious mind that they should be happening. Yet when something bad happens, like an illness, you may say to yourself, "How can this be? I haven't been sitting here asking to get this disease."
Consuming too much energy – whether from fat or carbohydrates, including sugar – will make you gain weight. If left unchecked, this excess weight increases your risk of lifestyle-related diseases such as diabetes, heart disease and some cancers.
"It's a little bit like some kind of Halloween stuff happening," says Omer Inan. "You're listening to your bones rubbing on each other, or maybe cartilage."
Have you ever wondered why you have so many different types of flour in your pantry? You might have cornflour and arrowroot, self-raising, and plain flour. And if you like to bake bread, possibly strong bakers’ flour.
The study shows that blue-enriched light exposure acutely altered metabolic function in both the morning and the evening compared to dim light
Osteoarthritis affects about eight million people in the UK, and rheumatoid arthritis a further half a million. Unfortunately, there is no cure. The most advanced treatments available today offer only limited relief from joint pain and swelling.
"A shift of attention is needed from disease-focused management, such as medications for hypertension or high cholesterol, to overall well-being across many areas," says William Dale.
Some of us are more ticklish than others, but nearly everyone is unable to tickle themselves. The answer is tied to how we see and how we perceive movement.
BBP is not used in food preparation, but it is used in the conveyor belts and plastic fittings on machines used to process many prepared foods. Food becomes contaminated when BBP leeches into it from the plastic.
"These findings provide us with a much better understanding of how this class of drugs may act upon the brain in ways that might raise the risk of cognitive impairment and dementia," says Shannon Risacher. "Physicians might want to consider alternatives to anticholinergic medications if available when working with their older patients."
Sitting quietly in the corner, we watch a daily family ritual: in the living room awash with soft afternoon light, a six-year-old boy is sitting on the floor, controller in hand, eyes firmly on the television screen. His fingers expertly guide the colorful character in Skylanders, from time to time glancing over his shoulder and grinning at the figure on the sofa, his 68-year-old grandmother.
"People who live in rural areas and who use private wells need to have their well water tested, particularly if they are thinking about becoming pregnant," Jean Brender says.
I taught myself about orphanages 12 years ago, not actually because of my work as a human biologist but because of my daughter. She was born in 2004 and her first 14 months of life were spent in an orphanage in China.
Hospital infections affect almost two million people in the United States every year, 100,000 of whom die. Up to 70 percent of these infections could be prevented if health care workers follow recommended protocols, which include hand hygiene.
Anyone who regularly uses social media will have had the experience of feeling envious of the fun their friends all seem to be having. This might especially be the case if you’re are sitting at home on a cold wet evening, feeling bored while everyone else is partying or having a glamorous holidays in the sun.
Even though most people don’t know much about chemicals in general or poisons in particular, virtually everyone knows that arsenic is bad. In the first century, arsenic was already known to be a deadly poison .
Regular participation in muscle strengthening activity such as weight or resistance training has many health benefits. However, this mode of exercise has been largely overlooked in health promotion.
"Prevention is key for fighting obesity, but until now, we didn't have any concrete evidence for guiding patients on how to prevent that weight gain," says Deborah Tate. "Now, for the first time, we do."
The opioid abuse epidemic is a full-fledged item in the 2016 campaign, and with it questions about how to combat the problem and treat people who are addicted.
Eating fast foods like hamburgers, sausages, and pizza, as well as commercial baked goods such as muffins, doughnuts, and croissants has been shown to be associated with an increased risk of depression.
"If older adults are more likely to have these pain messages sent through the spinal cord to the brain, and the nervous system is being adapted to go through these changes, they may become more pain prone," says Joseph Riley.
Children in Canada, their parents, health professionals and government ministers will welcome the news that there has been a decline in overweight and obese children over the past ten years. The reduction in the proportion of children in Canada who are overweight or obese is a rare achievement.
Chicken noodle soup is regarded as a therapeutic dish in several cultures, including Jewish-American and Chinese communities where traditional medicine is practised.
Almost every product we purchase, use in our homes or give to our children contains tens, if not hundreds, of chemicals. The United States chemical industry alone produced US$769.4 billion worth of chemicals in 2012.
Current guidelines suggest adults should accrue at least 150 minutes of moderate-intensity exercise each week. However, 60% of us fail to meet this recommendation, and around one in six aren’t doing any regular exercise at all.
The drugs are sold under the brand names Prevacid, Prilosec, Nexium, and Protonix, among others. More than 15 million Americans have prescriptions for PPIs, although the number of people taking PPIs is likely higher because the figure does not include PPIs bought over-the-counter without prescriptions.
The mind can be changed. I doubt whether anyone would dispute that point although we often feel as if we are stuck with an obstinate mind that refuses to do what we want it to. In addictions this feeling of being stuck can be very powerful. But...
“I’m vegetarian.” “I’m vegan.” These statements typically will be met with a range of reactions, varying from bafflement to praise. But what makes people adopt a vegetarian or vegan diet?
Drinking cherry concentrate can lower systolic blood pressure for up to three hours, our latest study found. If tart Montmorency cherry concentrate was a drug, it would probably get FDA approval.
Whether it’s your head, tooth or back, when you’re in pain, it’s hard to think about anything else. If it’s not too strong, some can ride it out. But in many cases, the pain just gets worse and won’t go away until you take something.
Anybody suffering from a food allergy will know what a huge cause of anxiety it can be. From forensically examining information on food packaging to having to repeatedly ask restaurant staff detailed questions about their ingredients, it can take up a lot of time and energy. And, even then, there are still uncertainties to deal with.
Historically called the disease of kings, gout was common among wealthy gents who could afford to eat and drink to excess. These days it doesn’t just affect the rich: rates of gout have been increasing globally since the 1960s. It now affects around 70,000 Australians a year and is more common in men aged over 70.
Most women will have been made aware they have a “biological clock” and that it’s ticking. Most know the older women become the harder it is for them to conceive. But most probably don’t know it’s because women are born with a limited supply of eggs, and eventually they will run out.
From believing that clouds are alien spaceships to thinking that MI6 agents are following you in unmarked cars, delusions are the hallmark of severe mental illness.
People who ate 100 grams of chocolate a day—basically one bar—had reduced insulin resistance and improved liver enzymes. Insulin sensitivity is a well-established risk factor to cardiovascular disease.
Conversation about how often you have to get up at night for a piddle is probably not the most scintillating discourse. But there’s a much bigger reason men don’t like to talk about prostate conditions.
Children who had vitamin D stores above the threshold recommended by the Canadian Pediatric Society averaged around 450 grams (or about one pound) less body fat at 3 years of age.
Although breast cancer is usually seen as a woman’s disease, around 145 Australian men were diagnosed with breast cancer in 2015, and around 25 died from it. A little under 1% of all breast cancers occur in men, so it is more common than most people think.
The calls and e-mails arrive as often as several times a week from people with concerns about drinking water. Some of the callers — who include homeowners, architects and builders — want to know why their water smells like gasoline.
How long you live depends in part on the genes you inherit. For example, those suffering from Werner’s syndrome have inherited two defective copies of a gene coding for an enzyme that is involved in DNA replication and repair.
"There's long been evidence suggesting that light and circadian rhythms profoundly influence our biology, and specifically the physiological response to stress," says Matthew R. Rosengart.
In case you’ve forgotten the section on the food web from high school biology, here’s a quick refresher. Plants make up the base of every food chain of the food web (also called the food cycle).
Whether a drug is prescribed by the doctor, bought over the counter or obtained illegally, we mostly take their mechanism of action for granted and trust they will do what they’re supposed to.
"The principal interest of this piece of work is that it provides direct evidence for early dairying at high altitude in the Alps," says Kevin Walsh.
Older adults who strength trained at least twice a week had 46 percent lower odds of death for any reason, 41 percent lower odds of cardiac death, and 19 percent lower odds of dying from cancer.
Even after taking into account residents' wealth, age, sex, and other neighborhood factors, the study found that having a view of the ocean was associated with improved mental health.
For some people, waking up every day means the start of persistent pain that affects their mood, thinking and relationships. This experience is more difficult when the pain doesn’t seem to have a cause; at least not a visible one.
The mice in the enriched environment, where they exercised more, lived anywhere from 16 to 22 percent longer than those in a deprived environment, depending on the level of gene expression.
A good night’s sleep is a crucial aspect to overall health and well-being, yet so many Americans are lacking in that department. A 2013 Gallup poll found that 40% of American adults get less than the recommended amount of sleep.
Beginning in infancy, people who have autism spectrum disorder observe and interpret images and social cues differently than others do. Researchers now have new insight into just how this occurs, which eventually may help doctors diagnose, and more effectively treat, the various forms of the disorder.
The people who consult me are often desperately scared. An illness threatens the length and quality of their lives. They want to be well. They want to be cured. They want a miracle. Unfortunately, miracles cannot be guaranteed or produced on demand...
