A Pediatrics analysis led by CDC statistician Amy Branum found reported childhood food allergies rose 18 percent from 1997 to 2007 and related emergency room visits tripled over a comparable decade. Peanuts, milk and shellfish are the most common triggers.

Heart & Blood
Vitamin D cuts risk of cardiovascular disease
Among 27,686 patients aged 50 and older with no prior cardiovascular disease, those with very low vitamin D were 77 percent more likely to die, 45 percent more likely to have coronary artery disease and 78 percent more likely to have a stroke than those with normal levels.
Diabetes
Vitamin D deficiency may boost type 1 diabetes risk
A case-control study in Pediatric Diabetes compared 50 Indian children newly diagnosed with type 1 diabetes to 50 without: average vitamin D was 20 ng/mL against 26, and deficiency appeared in 58 percent versus 32 percent. A Qatari study found a smaller but significant gap.
Diabetes
Drinking coffee may reduce risk of type 2 diabetes
Reviewing 18 cohort studies, Brazilian researchers found 14 showed substantially lower type 2 diabetes risk with frequent coffee drinking, with up to four cups a day linked to reduced risk and higher intake to a greater reduction. They call for more population surveys.

UNICEF finds 200 million children suffer from under-nutrition
A UNICEF report says 200 million children under five in the developing world are undernourished and stunted, and that under-nutrition contributes to more than a third of deaths in that age group. Ann Veneman calls the condition often invisible until it is severe.
Cancer
Obesity, dietary fats affect prostate cancer risk
In a study of 40 men aged 50 to 80, half with prostate cancer, BMI was higher among the patients but not significantly so, though it tracked with tumor aggressiveness. Their total, saturated and unsaturated fat intake was higher, and omega-3, vitamin C and lycopene intake lower.
Cancer
Obesity related to more than 100,000 cancer cases a year
The American Institute for Cancer Research estimates poor diet, inactivity and excess body fat account for more than 100,000 US cancer cases a year, including over 33,000 breast cancers. Panel member Laurence Kolonel cites esophageal, pancreatic, kidney, breast and colorectal cancers.
Other Diseases
Millions of U.S. children found Vitamin D deficient
Analyzing NHANES data on about 5,000 children aged 1 to 11, researchers found roughly 20 percent fell below 50 nmol/L of vitamin D and two-thirds below 75 nmol/L, including 92 percent of non-Hispanic black children. The authors urge supplements for all children.
Other Diseases
Sodium, Artificially Sweetened Drinks Linked to Kidney Function Decline
Two Nurses' Health Study analyses of more than 3,000 women linked higher dietary sodium to greater kidney function decline, and two or more daily servings of artificially sweetened soda to twice the odds of decline. Sugar-sweetened drinks showed no such link, and the reason is unknown.
Other Diseases
Vitamin D deficiency key contributor to end-stage renal disease
Analysing data on 13,000 Americans, Michal Melamed's team found those with the lowest 25(OH)D levels were 2.6 times as likely to end up on dialysis, and that vitamin D deficiency accounted for about 58 percent of the higher ESRD risk in African Americans. The link is associational.

Foods That Fight Cancer
The American Institute for Cancer Research argues that no single food prevents cancer, but that compounds in a mostly plant-based diet may work together, and that such a diet limits the weight gain implicated in several cancers. It recommends filling two-thirds of the plate with plant foods.

Vitamin D prevents breast cancer - study
A meta-analysis of 33 studies found women with high vitamin D intake were 9 percent less likely to develop breast cancer, and those in the highest quantile of circulating 25(OH)D 45 percent less likely. The highest calcium intakes went with 19 percent lower risk.
Obesity
Study Shows Pregnancy Weight Hard for Obese Women to Lose
Kaiser Permanente researchers studied 1,700 obese women who gave birth between 2000 and 2005; 70 percent exceeded the recommended weight gain. Those gaining 15 to 20 pounds were twice as likely to still carry 10 extra pounds 18 months later, and those gaining 35 or more, eight times.
Diabetes
Vitamin D may help reduce type 2 diabetes risk
In a six-month trial, 42 insulin-resistant South Asian women took 4,000 IU of vitamin D3 daily while 39 took placebo. Serum vitamin D rose from 21 to 75 nmol/L, and insulin sensitivity and resistance improved significantly, with the best results above 80 nmol/L.
Obesity
Another Weight Loss Benefit: Improved Kidney Function
Cleveland Clinic researchers pooled 13 studies and found weight loss, whether from diet and exercise or from surgery, reversed some kidney stress measured as protein in urine. Surgery patients were more likely to bring abnormally high filtration rates back down.
Diabetes
Nutrition notes:Diabetes Prevention: Never Too Old
Karen Collins reports on a study that followed 4,883 adults aged 65 and older for ten years and attributed 9 of 10 new diabetes cases to five lifestyle factors. Avoiding excess body fat alone cut risk almost 50%, and each additional healthy factor lowered the rate by 35%.
Obesity
Obesity may raise prostate cancer risk
Brenda Hernandez and colleagues at the University of Hawaii tracked 83,879 men, 5,554 of whom developed prostate cancer, and found the effect of weight varied by ethnicity: being overweight in older adulthood raised risk among white and Native Hawaiian men but not Japanese men.
