Recent research: American Journal of Clinical Nutrition on weight, sugared drinks, vitamin D, vegetarianism & climate change

I like the American Journal of Clinical Nutrition (AJCN).  It comes out monthly and nearly always has an article or two that I find interesting and helpful.  The AJCN May edition produced a bumper crop.  Interesting articles included a report by Chen and colleagues (see below for all abstracts) on the effects of encouraging people to reduce their consumption of sugar-sweetened beverages (SSB).  In the 810 US adults they studied, 19% of total daily energy intake came from drinks.  They found "A reduction in liquid calorie intake had a stronger effect than did a reduction in solid calorie intake on weight loss. Of the individual beverages, only intake of sugar-sweetened beverages (SSBs) was significantly associated with weight change. A reduction in SSB intake of 1 serving/d was associated with a weight loss of 0.49 kg ... at 6 mo and of 0.65 kg ...

Are you at risk of developing cancer from radon gas at home or at work?

Last month's article in the British Medical Journal on the dangers posed by radon gas in buildings jogged my awareness of this important hazard (Gray, Read et al. 2009).  Quoting Wikipedia on radon "Radon is the invisible, radioactive mono-atomic gas that results from radioactive decay of some forms of uranium that may be found in rock formations beneath buildings or in certain building materials themselves. There are relatively simple tests for radon gas, but these tests are not commonly done, even in areas of known systematic hazards." and "According to the United States Environmental Protection Agency, radon is reportedly the second most frequent cause of lung cancer, after cigarette smoking; and radon-induced lung cancer the 6th leading cause of cancer death overall." and "Some ... areas, including Cornwall and Aberdeenshire in the United Kingdom have high enough natural radiation levels that nuclear licensed sites cannot be built there - the sites would already exceed legal radiation limits before they opened, and the natural topsoil and rock would all have to be disposed of as low-level nuclear waste."
