Breakfast makes you mentally agile
Maybe grandma was right after all: breakfast is, indeed,
the most important meal of the day. Researchers at the University of Florida reviewed
47 nutrition studies and concluded that children and adolescents who ate breakfast
had better mental function and better school attendance records than those who
did not. And breakfast-eaters, even though they consumed more calories, were less
likely to be overweight than those who skipped breakfast. The review appears in
The Journal of the American Dietetic Association. According to the nutritionists,
eating breakfast improves memory and school performance for several possible reasons,
because it modulates short-term metabolic responses to fasting, causes changes
in neurotransmitter concentrations, or simply eliminates the distracting physiological
effects of hunger.
Women vulnerable to drink
Alcoholism isnt an equal-opportunity addiction,
report researchers from the Stanford University School of Medicine in California.
They studied the brains of men and women dependent on alcohol and found that the
latter became addicted to drinking more quickly than the former. Women also showed
brain shrinkage and deterioration at a faster rate. Earlier studies have suggested
that alcohol is more damaging to women than men, but most research involving brain
imaging to gauge alcohol effects on the brain has been conducted among men. The
results showed that all the alcoholics had greater amounts of brain shrinkage
than healthy people.
Sham acupuncture works too
A sham version of acupuncture works just as well
for treating migraine headaches as the real thing, and both fake and real acupuncture
work better than no treatment at all, a new study has found. In the study, reported
by the New York Times, German researchers divided 302 migraine-sufferers
into three groups. The patients were told that one group would receive a strictly
Chinese procedure, and another would receive an improvised method of acupuncture
which has been associated with positive outcomes in clinical studies.
The effectiveness of both the sham and the real acupuncture, the researchers write,
was about the same as treatment with drugs and had fewer side -effects. The results,
they conclude, may be due to nonspecific physiological effects of needling,
to a powerful placebo effect, or to a combination of both.
A turbocharger for heart
GenX medicine has gone so hi-tech that cardiologists
have begun using a turbocharger pumping aid to boost blood flow in
the heart. The implant consists of a balloon that inflates after a heart beat
to squeeze the blood into the main vessel that exits the heart.
