Researchers at the University of Sydney in Australia reported that people with the greatest average of vitamin A intake had a 47% less chance of developing hearing loss, while those taking more vitamin E reduced their risk by 14%. The study in The Journal of Nutrition, Health & Aging found that antioxidants provided by the vitamins may reduce age-related hearing loss by countering damage to the inner ear from reactive oxygen species.
A survey conducted by the CDC indicates that Southern states have the highest obesity rates at 29.4%, while Western states have the lowest at 24.1%. None of the states surveyed had an obesity rate below 20%, meaning that the Healthy People 2010 goal was not met. Mississippi is the most obese state, with 34% of adult residents having the condition, while Colorado is the least obese with a rate of 21%, the CDC said.
A study by registered dietitian Stephanie Smith found that students in the Thompson School District in Colorado threw out up to 50% of fruits and vegetables on their lunch plates. The district used the study data to consider ways to get children to eat healthy foods, such as having the items placed more prominently in the lunch line and better marketing.
Parents should refrain from preparing lunches containing foods such as hot dogs, peanuts and grapes for toddlers -- who haven't developed molars and the coordination to chew and swallow foods -- to avoid choking, Dr. Pam Okada says. She says that lunches can also pose hazards to older children with food allergies, and suggests each should carry an EpiPen, which holds one dose of epinephrine and can halt a severe allergic reaction.
Waist circumference may help predict mortality risk in obese individuals with chronic kidney disease, a study in the American Journal of Kidney Diseases suggests. Experts said the odds of dying from CKD were 2.1 times higher in men and women with waist sizes equal to or greater than 48 inches and 42.5 inches, respectively.
