Regular chocolate consumption may be linked to lower risk of heart flutter

Harvard and Alborg (Denmark) universities,

Regular chocolate consumption may be linked to a lower risk of developing the heart rhythm irregularity atrial fibrillation, also known as heart flutter, finds research published online in the journal Heart. The associations seemed to be strongest for 1 weekly serving for women and between 2 and 6 weekly servings for men, the findings suggest. They drew on 55,502 (26,400 men and 29,100 women) participants, aged between 50 and 64, from the population-based Danish Diet, Cancer and Health Study. Participants provided information on their usual weekly chocolate consumption, with one serving classified as 1 ounce (30 g). But they were not asked to specify which type of chocolate they ate. Most chocolate eaten in Denmark, however, is milk chocolate (minimum 30 per cent cocoa solids). When the data were analysed by sex, the incidence of atrial fibrillation was lower among women than among men irrespective of intake, but the associations between higher chocolate intake and lower risk of heart flutter remained even after accounting for potentially influential factors. The strongest association for women seemed to be 1 weekly serving of chocolate (21 per cent lower risk), while for men, it was 2 to 6 weekly servings (23 per cent lower risk).


Fruit and vegetable consumption and risk of lung cancer

Qingdao University (China)

According to news reporting originating in Shandong, People's Republic of China, A meta-analysis was conducted to summarize evidence from prospective cohort studies about the association of fruit and vegetable consumption with the risk of lung cancer. A random-effects model was used to combine study-specific relative risks and 95% confidence interval. Dose-response relationship was assessed by restricted cubic spline. The RR (95% CI) of lung cancer for highest versus lowest category of fruit and vegetable (FV) consumption was 0.87 (8 studies including 12,942 cases among 1,571,494 subjects), and the effect was 0.84 for fruit (16 studies including 15,421 cases among 1,791,469 subjects) and 0.90 for vegetable (19 studies including 16,422 cases among 1,877,375 subjects).


Going For A 10-Minute Power Walk Every Day Could Be Secret To Long Life

National Cancer Institute

Could a 10-minute power walk every day could add years to your life? A recent study of nearly 5,000 older adults found that deaths fell as physical activity increased. Just 10, 20, or 30 minutes extra exercise a day per day reduced annual mortality rates by seven, 13 and 17 percent respectively. The research is based on Americans aged 40 to 85 who wore accelerometers on their waist for a week. Volunteers were tracked for an average of ten years, during which time 1,165 deaths occurred. The study shows that adding 10 minutes of physical activity each day resulted in an estimated 111,174 preventable deaths per year. Not surprisingly, the more physical activity, the more deaths prevented. The number almost doubled and tripled to 209,459 and 367,037, respectively, for 20 and 30 minutes. Similar results were observed for men and women, including those of all ethnic backgrounds.


Whey protein improves blood glucose in diabetics

Newcastle University (UK),

A study reported in BMJ Open Diabetes Research & Care resulted in improved glucose control among people with type 2 diabetes who consumed whey protein. The crossover study included 18 type 2 diabetic men and women who received a drink that contained 15 grams of whey protein or a protein-depleted placebo to be consumed 10 minutes before breakfast, lunch and dinner for 7 days. This was followed by a 2-week period during which no treatments were given. Participants who had previously received whey were then given a placebo and those who received the placebo were given whey for an additional 7 days. Continuous glucose monitoring revealed improved daily blood glucose levels in association with whey intake. Participants experienced an increase of 2 hours per day of normal glucose during the week in which whey was consumed in comparison with the week in which the placebo was administered.
