Resetting the circadian clock: Shift workers might want to skip high-iron foods at night

Posted: 21 Oct 2014 10:48 AM PDT

Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don't disrupt the circadian clock in their livers. "Iron is like the dial that sets the timing of the clock," the lead researcher says. "Discovering a factor, such as iron, that sets the circadian rhythm of the liver may have broad implications for people who do shift work."

An new animal study reveals potential brain-health benefits of a walnut-enriched diet. Researchers suggest that a diet including walnuts may have a beneficial effect in reducing the risk, delaying the onset, slowing the progression of, or preventing Alzheimer's disease.

Animal therapy reduces anxiety, loneliness symptoms in college students

Posted: 21 Oct 2014 09:56 AM PDT

Animal-assisted therapy can reduce symptoms of anxiety and loneliness among college students, according to researchers who provided animal-assisted therapy to 55 students in a group setting at a small arts college. They found a 60 percent decrease in self-reported anxiety and loneliness symptoms following animal-assisted therapy, in which a registered therapy dog was under the supervision of a licensed mental health practitioner.

Memory decline among menopausal women could be next research frontier for hypnotic relaxation therapy

Posted: 21 Oct 2014 08:07 AM PDT

Memory decline — a frequent complaint of menopausal women — potentially could be lessened by hypnotic relaxation therapy, say researchers who already have done studies showing that such therapy eases hot flashes, improves sleep and reduces stress in menopausal women.

Misreporting diet information could impact nutrition recommendations for Hispanics

Posted: 21 Oct 2014 07:16 AM PDT

Faulty self-reporting of the food we eat can lead to incorrect conclusions about whether we are meeting dietary recommendations for certain essential nutrients, say researchers. A new study is the first to examine how accounting for the problem of misreporting affects nutrient intake estimates in the Hispanic community. Nearly one in three US residents is projected to be Hispanic in 2060.

Hungry or not, kids will eat treats

Posted: 21 Oct 2014 07:16 AM PDT

Even though they are not hungry, children as young as three will find high-energy treats too tempting to refuse, new research has confirmed. In a study of three and four year olds, 100 per cent of children opted for a sweet or savory snack despite eating a filling healthy lunch only 15 minutes prior.

Child's poor decision-making skills can predict later behavior problems, research shows

Posted: 21 Oct 2014 07:16 AM PDT

Children who show poor decision-making skills at age 10 or 11 may be more likely to experience interpersonal and behavioral difficulties that have the potential to lead to high-risk health behavior in their teen years, according to a new study.

New viral mutation made middle-aged adults more susceptible to last year's flu

Posted: 21 Oct 2014 07:15 AM PDT

A possible explanation for why middle-aged adults were hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season has been uncovered by scientists. Their findings offer evidence that a new mutation in H1N1 viruses potentially led to more disease in these individuals.

A rich vocabulary can protect against cognitive impairment

Posted: 21 Oct 2014 05:55 AM PDT

Some people suffer incipient dementia as they get older. To make up for this loss, the brain's cognitive reserve is put to the test. Researchers have studied what factors can help to improve this ability and they conclude that having a higher level of vocabulary is one such factor. 'Cognitive reserve' is the name given to the brain's capacity to compensate for the loss of its functions. This reserve cannot be measured directly; rather, it is calculated through indicators believed to increase this capacity.

People who visited their doctor at least twice a year had better blood pressure control, a study shows. Having healthcare insurance and getting treated for high cholesterol also increased the likelihood of controlling blood pressure.

Exposure to traffic pollution during pregnancy can damage future child's lungs

Posted: 20 Oct 2014 06:25 PM PDT

Women who are exposed to traffic pollution while pregnant are increasing the chances of damaging the lungs of their unborn children, concludes a study. Nitrogen dioxide (NO2) is a widely used marker of traffic-related air pollution, and benzene levels can reflect industrial activities and are considered as a surrogate for a mixture of predominantly traffic-driven pollutants. Both were used as indicators of pollution in the areas in which the women lived.

Heart attacks do not have as strong of a genetic link as previously suspected

Posted: 20 Oct 2014 06:23 PM PDT

Heart attacks are not as connected to family history and genetics as may have been previously believed, according to a new study. These new findings may help those with a family history of coronary disease and those diagnosed with narrow coronaries realize that heart attacks aren't inevitable and that their lifestyle choices and environment, not just their genetics, may make the difference in whether or not they have a heart attack, say researchers.
