Being depressed can negatively affect your appetite and what you eat, but can bad eating habits bring your mood down? Our latest study, a systematic review of the best available evidence, found a clear link between the quality of a person’s diet and their risk of depression. And it goes beyond the effect of diet on body size or other aspects of health that can affect mental health.

It can often be tempting to jump on a bus for a short journey through the city, especially when it’s raining or you’re running behind schedule. Where there are dedicated bus lanes in place, it can feel as though you speed past gridlocked traffic. But as city authorities begin new initiatives to get people walking or cycling, that could all change – and so could you.

The Fountain of Youth may still be a myth, but a longer life expectancy is now a reality. In fact, life expectancy at birth in the U.S. has risen by more than 30 years in barely more than a century to a current 78.6 years.

If you have ever broken an arm and had to wear a cast or splint for a few weeks, you will be familiar with the alarming loss of muscle and uneasy feeling of weakness experienced after removing your cast.

It can be difficult to find reliable information online on timing and how to introduce foods – and how to balance that with breastfeeding. Here’s what the recommendations say, and the science behind them.

Baby boomers, who once viewed themselves as the coolest generation in history, are now turning their thoughts away from such things as partying and touring alongside rock bands to how to they can stay healthy as they age. And, one of the most important parts of healthy aging is avoiding a fall, the number one cause of accidental death among people 65 and older.

If you plan to try and quit eating junk food, expect to suffer similar withdrawal-type symptoms—at least during the initial week—that addicts experience when they attempt to quit using drugs, according to new research.

New research with mice may upend our understanding of the connection between the gut and the brain, as well as appetite. If you’ve ever felt nauseous before an important presentation, or foggy after a big meal, then you know the power of the gut-brain connection.

Tonight ABC’s Four Corners will air the first of a two-part investigation into the often shocking treatment of the elderly in aged care homes around Australia.

Ancel and Margaret Keys, an American husband-and-wife team, first reported on the Mediterranean diet’s health benefits in 1975. Since then, the diet has become particularly well known for its effect on cardiovascular health. What is less well known is whether the diet has different benefits for men and women. Our latest study sheds some light on the matter.

In our survey of yogurts sold in the UK, we found that less than 10% were low sugar – almost none of which were children’s yogurts. We also found that organic products, often viewed as healthier options, contained some of the highest levels of sugar.

Carbon monoxide (CO), like many gases, cannot be detected by our human senses. We cannot see it, smell it or taste it. But unlike many gases, small amounts are extremely harmful to us.

If you’re having trouble sleeping, medicines shouldn’t be your first option. Exercise regularly, cut back on coffee (and other caffeinated drinks) after midday, eat less in the evening, ease up on “screen time” before, and in, bed, practise meditation and try to have a quiet, dark bedroom dedicated mostly to sleep.

Legalized cannabis is just a month away, but Ontario won’t have any cannabis stores until April. That’s due to the province’s recent decision to have cannabis outlets run by businesses rather than a government agency, although the agency will still open a retail web site Oct. 17.

Keeping household surfaces clean is a daily chore for most families, but there may be unseen consequences for children’s health.

When my brother and I were kids back in the ‘80s, we loved going to Long John Silver’s. But it wasn’t just for the fish. It was for the vinegar – malt vinegar. We would uncap a bottle at the table and swig that tangy, delicious nectar of the gods straight.

Researchers have developed a way to reliably predict which chronic pain patients will respond to a sugar placebo pill based on brain anatomy and psychological characteristics. Doctors may one day prescribe placebos that work as effectively as any painkiller for certain patients, the researchers’ new study suggests

Taking low-dose aspirin daily doesn’t preserve good health or delay the onset of disability or dementia in healthy older people. This was one finding from our seven-year study that included more than 19,000 older people from Australia and the US.

While the ageing of society has become one of the givens in today’s world, less is made of the lived experience of the very elderly in society.

Researchers have discovered evidence of the earliest brewmasters to date, a finding that might stir an old debate: What came first, beer or bread?

Two of every three US consumers surveyed report eating less of at least one type of meat, according to new research. “Many Americans continue to have strong preferences for meat,” says Roni Neff, an assistant professor of environmental health and engineering at Johns Hopkins University.

Or you put your kids on the bus to elementary school and the 57 year-old driver forgets the route. These are real scenarios, drawn from my clinical work with patients who have young-onset Alzheimer’s disease.
