Recent research: American Journal of Clinical Nutrition on weight, sugared drinks, vitamin D, vegetarianism & climate change
Last updated on 2nd December 2009
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 ...

In 2001 the World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) WCRF/AICR set themselves the task of systematically assessing all good research on diet, physical activity and cancer and publishing a report that would be the largest study of its kind with conclusions that would be best the evidence could demonstrate. Over 100 scientists from 30 countries were involved. An expert panel of 21 of these scientists worked for 5 years to produce the report "Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective." The follow-up companion Policy Report "Policy and Action for Cancer Prevention" was published a little over a month ago and has recommendations for a series of different groups and organizations including government, industry, the media, schools, and work places.

Fish, fish oils, and n-3 fatty acids are often in the health news. Here are seven recent papers illustrating the breadth of fish oil relevance. The papers look at treatment of rheumatoid arthritis, the potential of flax as a dietary source of n-3 fatty acids, effects on indicators of cardiovascular disease, potential protection against dementia, reduction in mortality, and importance in pregnancy. The papers also illustrate the patchwork, three steps forward/one step back, meandering, spreading, accretion of scientific knowledge. As the proverb goes "One swallow doesn't make a summer". Similarly, a single research study is usually simply one brick in the gradual building of our knowledge. For more on fish and n-3 fatty acids, see other relevant blog posts I've written, articles in the linked Connotea database, and some recommended websites.
... the current system for bringing promising biomedical research to the bedside is operating at an obsolete level of efficiency, causing great delay, and consequently resulting in the loss of many lives. - Roger Rosenberg (JAMA 2003;289:1305-6)
Here are a series of information and assessment handouts on alcohol and food. "We are what we eat" is bit over-simplified, but only a bit. It's amazing how important what we eat and drink is for our psychological and physical health. This site's blog posts "New research shows diet's importance for preventing depression" and "Preventing cancer through life style choices" make this point well and also provide links with many other sources of information. Searching the tag cloud brings up much recent relevant research and advice. Try clicking, for example, on
