Number of minutes it takes for people to feel full after they start
eating—except in the overweight. Among the obese, it takes 20
minutes for the brain to respond to the changing hormone levels in the
body that signal satiety. If you're trying to lose weight, it makes sense
to slow the pace of eating.
Images of the ideal
According to researchers at the university of missouri, media
images indicate that today's “ideal” woman is 5'7”,
weighs 100 pounds, wears a size 5, and has blond hair and blue eyes. And
it takes only one to three minutes of exposure to such images for viewers
to experience a drop in satisfaction with their own body.
Ooops. Think again
Nine out of 10 parents think they can spot depression in their
teenage kids—but they're wrong, finds a columbia university study.
About 5% of adolescents suffer from depression, and two thirds of them
are never diagnosed. Most go to great lengths to hide their
distress.
A problem to chew on
You know all the ways secondhand smoke is bad. Now add a new one.
Secondhand smoke can cause tooth decay in kids, according to a study of
nearly 4,00 children aged four to 11. High levels of cotinine, a
byproduct of nicotine found in smoke, erode tooth enamel. About 32% of
kids exposed to high concentrations of cotinine had decay on their baby
teeth, compared to 18% of those growing up in smoke-free
environments.
Organic is better
Yes, virginia, organic foods do make a difference. Fruits and
veggies grown without pesticides are richer in antioxidants than
conventionally grown food, say researchers who find that bug- and
weed-killers limit a plant's production of these naturally protective
substances. Organic and sustainably grown plants (fed fertilizer but no
pesticides) contain 50% more phenolics, antioxidants known to protect the
human body against cancer, heart disease and the ravages of age.
