How evil is sugar? That's long been a hard question for researchers to answer. Most of the studies about sugar's health effects to date have been too small, too short-term, or too poorly designed to nail it one way or another.
UPDATE at 12:35 p.m., ET, Jan. 17: Many of you wrote in to tell us you were taken aback by Whole Foods top executive John Mackey characterizing the health law as fascism in an NPR interview, and apparently, he's feeling a little sheepish.
About three minutes into his otherwise amiable chat with CBS This Morning hosts on on Thursday, Mackey walked back his comments in response to a direct question from Norah O'Donnell:
Being a little overweight may tip the odds in favor of living a long life, according to a new analysis. Researchers say there may be some benefit to having a little extra body fat.
This isn't the first time researchers have raised questions about the link between body weight and how long someone will live. While there's no debate that being severely obese will raise the risk of all kinds of illnesses and even cut some lives short, it's less clear what happens to people who are less overweight.
The millions of Americans who make New Year's resolutions to lose weight often have pictures in mind.
They're pictures that have been repeatedly supplied by the health and beauty magazines at supermarket checkout lines. They feature skinny models in bikinis, or toned guys with six-pack abs, and captions about how you could look like this by summer.
Some people go so far as to tape these pictures onto their refrigerators and cupboards. When they're tempted to reach for a cookie, they reason, the sight of that toned model might dissuade them from breaking their resolutions.
