Health Points: Friday

More than three-quarters of obese Americans say they have healthy eating habits, according to a survey of more than 11,000 people.

About 40 percent of obese people also said they do "vigorous" exercise at least three times a week, the telephone survey found.

"There is, perhaps, some denial going on. Or there is a lack of understanding of what does it mean to be eating healthy, and what is vigorous exercise," said Dr. David Schutt of Thomson Medstat, the Michigan-based health-care research firm that conducted the survey.
Heat exhaustion symptoms:
* Often pale with cool, moist skin
* Sweating profusely
* Feels faint or has collapsed
* May be complaining of headache, weakness, thirst, and nausea
* Core (rectal) temperature elevated—usually more than 100°F—and the pulse rate increased

Heat stroke:
* Unconscious or has a markedly abnormal mental status
* Flushed, hot, and dry skin (although it may be moist initially from previous sweating or from attempts to cool the person with water)
* May experience dizziness, confusion, or delirium
* May have slightly elevated blood pressure at first that falls later
* May be hyperventilating
* Rectal (core) temperature of 105°F or more
In the test, the researchers used three different types, or cultivars, of watermelon, storing them separately at 41 degrees (refrigerator temperature), 55 degrees and 70 degrees for 14 days. The findings appear in the Aug. 9 issue of The Journal of Agricultural and Food Chemistry. Watermelons contain significant amounts of lycopene, which is also found in tomatoes and a few other fruits and vegetables. Lycopene, an efficient scavenger of free radicals, has been associated with various beneficial health effects, including a reduced risk of prostate cancer.

At 41 and 55 degrees, the lycopene content changed little compared with fruit fresh off the vine. But the content when stored at room temperature increased as much as 40 percent in some types.
The researchers believe this is due to a 'survival preference': in times of food shortage - a heavier woman becomes ideal. They also point to physiological factors (blood sugar, hormones) that may affect drives and interests.

To be honest, this sounds like a bunch of male university students (going to and from the dining hall no less) playing a 'hot-or-not' game... However the researchers do plan to see how hunger impacts female attraction to men.
