Eating curry has unexpected health benefit after study finds it improves your memory

Eating curry has unexpected health benefit after study finds it improves your memory

Scientists have uncovered some good news for curry fans, as the popular dish could boast some unexpected health benefits.

Research has found that a key ingredient can both improve your mood and your memory.

A study published in the American Journal of Geriatric Psychiatry reveals that people regularly taking curcumin performed better in memory tests and had longer attention spans.

Curcumin goes into in tumeric, which is used in curry.

Following the study, author Dr Gary Small said, according to Science Daily : “Exactly how curcumin exerts its effects is not certain, but it may be due to its ability to reduce brain inflammation, which has been linked to both Alzheimer’s disease and major depression.”

Even one cigarette a day can still kill you, study finds

Even one cigarette a day can still kill you, study finds

If you think having just one cigarette a day won’t do any harm, you’re wrong. British researchers say lighting up just once a day was linked to a much higher risk of heart disease and stroke than might be expected.

The bottom line: “No safe level of smoking exists for cardiovascular disease,” wrote the team led by Allan Hacksaw, of UCL Cancer Institute at University College, London.

“Smokers should quit instead of cutting down, using appropriate cessation aids if needed, to significantly reduce their risk,” the study authors said.

And it’s a warning to the young that even so-called “light” smoking carries a heavy price, one expert said.

Young adults “often smoke lesser amounts than older adults,” noted Patricia Folan, who directs the Center for Tobacco Control at Northwell Health, in Great Neck, N.Y.

High-cholesterol diet causes tumours to form 100 times faster

High-cholesterol diet causes tumours to form 100 times faster

High-cholesterol diets send cancer cells into overdrive and cause tumours to grow 100 times faster, according to new research.

Scientists have shown for the first time the mechanism which means fatty cholesterol significantly increases the risk of colon cancers, opening the door for new drugs which could prevent this.

As well as looking at ways this cancer-boosting pathway could be blocked, researchers from University of California Los Angeles (UCLA) who made the discovery are investigating whether other forms of cancer are also sent into similar growth frenzy by high levels of cholesterol.

“We were excited to find that cholesterol influences the growth of stem cells in the intestines, which in turn accelerates the rate of tumour formation by more than 100-fold,” said Dr Peter Tontonoz from UCLA’s David Geffen School of Medicine.

”While the connection between dietary cholesterol and colon cancer is well established, no one has previously explained the mechanism behind it.”

Cholesterol is an essential component of the outer membrane of all human cells and is produced in the liver as an essential building block for other key substances.

A bedtime to-do list could help you sleep better

A bedtime to-do list could help you sleep better

For better shut-eye, don’t count blessings or sheep at bedtime; take stock instead.

A small but intriguing study found that writing a to-do list before turning in helps people get to sleep faster.

The reason? The mental housekeeping “offloaded” worry about what’s upcoming, according to research in the Journal of Experimental Psychology.

The study, led by Michael K. Scullin, Director of the Sleep Neuroscience and Cognition Laboratory in Baylor University’s department of Psychology, involved a team of researchers following 57 student volunteers. Each volunteer spent one night sleeping in the lab.

Drinking alcohol raises risk of cancer by snapping DNA, scientists find

Drinking alcohol raises risk of cancer by snapping DNA, scientists find

Drinking alcohol raises the risk of cancer by damaging DNA, scientists have discovered for the first time, leading health experts to call for people to cut down on their consumption.

Alcohol is contributes to more than 12,000 cases of cancer each year in Britain, but nobody had shown why it was so harmful.

Now a new study by the Medical Research Council Laboratory of Molecular Biology at Cambridge University, has found that when the body processes alcohol it produces a chemical called acetaldehyde which is harmful to DNA.

The damage happens in blood stem cells, which create the red and white blood cells that carry oxygen through the body and help fight infections.

The researchers found that acetaldehyde snaps the DNA of stem cells, permanently altering the genetic code and triggering cancer.

Eating fish may help you sleep better

Eating fish may help you sleep better

Forget warm milk. A new study from the University of Pennsylvania says that fish may be the key to a good night’s sleep.

The paper, published Thursday in Scientific Reports, found an association between regular fish consumption and high sleep quality among Chinese schoolchildren, likely thanks to the omega-3 fatty acids found in fish. Largely as a result of that improved sleep, the researchers found, the children also scored higher on IQ tests.

“There’s a relationship between fish consumption and higher cognitive functioning. What what we document here is that it’s the better sleep that explains the relationship,” says Adrian Raine, one of the paper’s authors and a professor of criminology, psychiatry and psychology at Penn. “From A to B to C: From fish consumption to better sleep to higher cognitive functioning.”

 The researchers asked 541 schoolchildren in China between ages 9 and 11 to describe their eating habits, including how often they ate fish. Their parents, meanwhile, were asked to answer questions about the kids’ sleep patterns. Researchers then administered IQ tests when the children turned 12.They found links between eating fish regularly — the more, the better — and both improved sleep and higher IQ scores. But, Raine explains, it appears that many of the cognitive benefits can be traced back to bedtime. “The brain is so much more plastic early on in child development,” he says. “We might anticipate that fish consumption earlier in life may be particularly beneficial for a child’s sleep and cognitive functioning.”

Better sleep linked with higher omega-3 levels in new study

Better sleep linked with higher omega-3 levels in new study

Omega-3 fatty acids are most commonly derived from fish oils, including tuna and salmon, and they have been linked to numerous health benefits. But now, a new study suggests that having higher levels of omega-3 DHA is associated with better sleep.

The researchers, from the University of Oxford in the UK, have published results of their study in the Journal of Sleep Research.

They conducted their research in 362 children from the UK between the ages of 7 and 9 years old, who were not recruited based on sleep problems.

According to the study, sleep problems in children are associated with poor health and behavioral and cognitive problems, the same health issues associated with deficiencies of long-chain omega-3 fatty acids.

As such, the team investigated whether taking 600 mg supplements of omega-3 DHA would improve sleep.

Sleep yourself slim: how an extra 90 mins in bed can stop sugar cravings

Sleep yourself slim: how an extra 90 mins in bed can stop sugar cravings

Spending an extra 90 minutes in bed may not seem like the obvious way to lose weight, but according to a new study, it could be the key to shedding excess pounds.

Scientists from King’s College London have discovered that people who sleep for longer are less likely to pick sugary treats, or reach for comforting carbohydrates.

Lack of sleep was already known to be a risk factor for obesity because it alters levels of hormones which control appetite.

But a new study showed that by getting more sleep, people naturally choose healthier foods within a week, eating on average 10 grams less sugar each day.

Using glass to fix broken bones

Using glass to fix broken bones

Glass may not seem an obvious material for a bone replacement. But UK surgeons are finding that bioglass not only is stronger than bone: it can bend, bounce and even fight infection.

In 2002, Ian Thompson, a specialist in facial reconstruction at King’s College, London, received an urgent phone call. A patient in his late 20s had been struck by an out-of-control car mounting the pavement. The impact had sent him catapulting over the bonnet of the car, smashing his face and shattering the fragile orbital floor – the tiny bone, no more than 1mm thick, which holds the eyeball in place in the skull.

“Without the orbital floor, your eye moves backwards into the skull, almost as a defensive mechanism,” Thompson explains. “But this results in blurred vision and lack of focus. This patient had also lost the ability to perceive colour. His job involved rewiring aircraft and as he could no longer detect a red wire from a blue one, he’d barely been able to work in three years.”

The accident had happened three years earlier. Since then, surgeons had desperately tried to reconstruct the bony floor and push the eye back into position, first using material implants and then bone from the patient’s own rib. Both attempts had failed. Each time, infection set in after a few months, causing extreme pain. And now the doctors were out of ideas.
