Eating baked or grilled fish on a weekly basis may improve brain health and reduce the risk of developing Alzheimer's disease.
A decade-long study of 260 healthy people found eating baked or grilled fish each week helped preserve grey matter volumes a crucial to brain health a and increased levels of cognition. Eating fried fish did not have the same effects.
Researchers at the University of Pittsburgh said their study was the first to establish a direct relationship between eating fish, brain structure and Alzheimer's risk.
aThe results showed that people who consumed baked or broiled (grilled) fish at least once a week had better preservation of grey matter volume on MRI in brain areas at risk of Alzheimer's disease,a researcher Cyrus Raji said.
Creative people are more likely to cheat than less creative people, psychologists believe.
Researchers from Harvard University and Duke University carried out a series of experiments to see if more creative people would cheat under circumstances where they could justify their bad behaviour.
Participants were paid a small sum for showing up and were given tasks for which they could be paid more if they cheated.
The more creative types were significantly more likely to cheat than other participants.
aThe results ... indicate that, in fact, people who are creative or work in environments that promote creative thinking may be the most at risk when they face ethical dilemmas,a the researchers wrote in their study, published by the American Psychological Association.
Having depression could raise your heart attack chances.
The theory is based on a Canadian study which found depressed people take longer to recover from exercise compared to those who are not depressed.
The study's authors suggested there was a dysfunctional biological stress system at play among depressed individuals, who they said should be tested for cardiovascular disease.
aThere have been two competing theories as to why depression is linked to cardiovascular disease,a lead researcher Jennifer Gordon, of McGill University, said.
aDepressed people may have poorer health …
