"No man is an island entire of itself; every man is a piece of the continent, a part of the main."  John Donne

I read a lot of research.  When I find an article of particular interest I download it to my bibliographic database - EndNote - which currently contains nearly 14,000 abstracts. 

Here are a mixed bag of six recent research papers on diet, vitamin D, IBS and yoga (all details & abstracts to these studies are listed further down this blog post).  The first three papers highlight the toxic effects on psychological health, physical health, and society of our processed, high sugar diets.  Sanchez-Villegas et al map a bit more clearly the potential link between diet and depression.  They conclude "Our results suggest a potential protective role of the MDP (Mediterranean dietary pattern) with regard to the prevention of depressive disorders; additional longitudinal studies and trials are needed to confirm these findings."  Fiorito et al show that intake of sweetened drinks in 5 year old girls predicts overweight over subsequent childhood and adolescence, and - rather scarily - Moore & colleagues show a link between confectionary consumption at age 10 and subsequent violence in adulthood.  They concluded "Children who ate confectio

Here are half a dozen studies on weight, bite size, vitamin D, dietary supplements, and ways of avoiding dementia.  Andrew et al report on the "Incident cancer burden attributable to excess body mass index in 30 European countries" estimating that about 6% of cancers could be avoided if we could maintain healthier weights (abstracts & links for all six articles mentioned appear further down this page).  Zijlstra and colleagues suggest a possible response!  They randomized subjects to eating with different bite (mouthful) sizes and different chewing times.  They found that " ... greater oral sensory exposure to a product, by eating with small bite sizes rather than with large bite sizes and increasing OPT (oral processing time), significantly decreases food intake."  As Mum might put it "Don't wolf your food!"

Here are half a dozen studies on diet (see below for all abstracts and links).  The first three are about the benefits of healthy lifestyle.  Trichopoulou & colleagues evaluated the contribution of nine widely accepted components of the Mediterranean diet (high intake of vegetables, fruits and nuts, legumes, fish, and cereals; low intake of meat and dairy; high ratio of monounsaturated to saturated lipids; and moderate intake of ethanol) in the inverse association of this diet with all cause mortality.  They concluded that "The dominant components of the Mediterranean diet score as a predictor of lower mortality are moderate consumption of ethanol, low consumption of meat and meat products, and high consumption of vegetables, fruits and nuts, olive oil, and legumes.

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 ...

Here are half a dozen papers on helping kids and adolescents.  The Fuligni et al paper found that adolescents experiencing frequent interpersonal stresses tended to have increased levels of C-reactive protein, " ... an inflammatory marker that is a key indicator of cardiovascular risk ... ".  Jackson et al showed that in preschool kids each extra hour of regular TV viewing is associated with an extra 1 kg of body fat.  This appeared to be due to increases in calorie intake rather than reduction in physical activity.  Decreased family accommodation is associated with improved outcome in paediatric OCD, Merlo et al found.  Naylor et al found that a six lesson teaching block on mental health benefitted young teenagers.  Proctor et al provide a free full text overview of teenage life satisfaction assessment measures, while Wilkinson and colleagues report on 28 week follow-up in a treatment trial for depressed adolescents.  The authors found "Depression at 28 weeks was predicted by the additive effects of severity, obsessive-compulsive disorder and suicidal ideation at entry together with presence of at least one disappointing life event over the follow-up period.
