Pop quiz, hotshot. There's a bomb on a bus. Once the bus goes 50 miles an hour... Who fares worst health-wise, diet soda drinkers or fried food eaters? Surprisingly, researchers have found a correlation between diet soda consumption and metabolic syndrome.
The one-third who ate the most fried food increased their risk by 25 percent compared with the one-third who ate the least, and surprisingly, the risk of developing metabolic syndrome was 34 percent higher among those who drank one can of diet soda a day compared with those who drank none.
What I Learned Today did some further digging and found a different study that links diet soda consumption and obesity.
For diet soft-drink drinkers, the risk of becoming overweight or obese was:
- 36.5% for up to 1/2 can each day
- 37.5% for 1/2 to one can each day
- 54.5% for 1 to 2 cans each day
- 57.1% for more than 2 cans each day.
Remember Dove's Evolution video of a fashion model going from drab to fabulous with the help of makeup and Photoshop? They've got a new video out called Onslaught in which we see the barrage of images that are directed at young girls each day. BTW, Dove's parent company makes all sorts of products that may contibute to the problem that Dove is attacking here. (via debbie millman)
A new study shows that if a person's friends become obese, that person is at a great risk of obesity themselves. For close mutual friends, the risk factor for transmitted obesity increased by 171%.
Update: Dr. Jonathan Robison calls the above study "junk science". "How does one conclude a direct causal relationship from an observational study? Bald men are more likely than men with a full head of hair to have a heart attack. Can we conclude from this that they should buy a toupee or begin using Rogaine lotion to lower their risk?" (thx, robby)
"A six-year Greek study found that those who took a 30-minute siesta at least three times a week had a 37% lower risk of heart-related death." Among working men, the risk was reduced by 64%. Naps all around!
A recent study concludes that in terms of life expectancy, there are eight different Americas, all with differing levels of health. "In 2001, 15-year-old blacks in high-risk city areas were three to four times more likely than Asians to die before age 60, and four to five times more likely before age 45. In fact, young black men living in poor, high-crime urban America have death risks similar to people living in Russia or sub-Saharan Africa." If I'm reading this right, it's interesting that geography or income doesn't have that big of an impact on the life expectancy of Asians; it's their Asian-ness (either cultural, genetic, or both) that's the key factor. Here's the study itself. (via 3qd)
Five reasons why Americans might be getting fatter that you haven't thought of. "Sleep-deprived animals eat excessively, and humans subject to sleep deprivation show increased appetite and an increased Body Mass Index, the standard measure of excessive weight."
As France becomes more like the US in eating habits, the famously thin French are getting fatter. "Some of the reasons for the increase in obesity are those that plague the United States and much of Europe: the lure of fast food and prepared foods, the ubiquity of unhealthy snacks and sedentary lives."
Study: people eat more when food is close at hand and in sight and less when its farther away and out of sight.
Interview with Soso Whaley, director of Mickey D's and Me, counterpoint to Morgan Spurlock's Super Size Me. "Even without seeing [Super Size Me] I could tell from the clips and the description by Spurlock that this was nothing more than junk science masquerading as legitimate scientific discovery."
