Brain study suggests obese people have less control over cravings
Using brain scans to detect impulse control, researchers found that obese participants showed little activity in the prefrontal cortex compared with their leaner counterparts when presented with images of high-calorie foods. The study, published in the Journal of Clinical Investigation, suggests that the brains of some obese people are less able to control cravings, but further investigation is needed, a researcher said.

Virgin olive oil diet is better than drugs for heart disease
A Spanish cohort study of 7,500 people with heart disease reports that diets heavily featuring olive oil and nuts are more effective than drugs in preventing cardiac events. "A modification in the entire diet pattern managed to achieve, in just one year, results that pharmaceutical drugs did not -- even after two years of treatment," said the researchers. The benefit was detected only in patients already showing a thickened artery wall. NutraIngredients (9/19)
Data: Americans get twice the recommended amount of sugarU.S. adults consume an average of 22.2 teaspoons of sugar daily, equivalent to 355 calories, which is more than double the approximately 9.4 teaspoons recommended for men and 6.25 teaspoons for women, according to data from a food industry analyst. The American Heart Association says a high-sugar diet is linked to obesity, elevated blood pressure and cardiovascular diseases. United Press International (4/30)
Data find heart-healthy benefits of apples in womenWomen who consumed one serving of dried apples every day for a year experienced a 14% reduction in total cholesterol, a 23% drop in LDL cholesterol and about a one-third decrease in levels of lipid hydroperoxide and C-reactive protein, while those who ate prunes daily had relatively smaller reductions in such heart markers, according to a study. The researchers also found that women in the apple group lost about 3 pounds over the course of the year. WebMD (4/12)
Obesity raises risk of many cancers, for many reasonsObesity raises the risk of many types of cancer, including colorectal, pancreatic, esophageal and gallbladder. Dr. Kate Wolin of Siteman Cancer Center said the way obesity affects cancer risk is different for each type, noting some cancers might be affected by fat tissue's hormonal effect or by inflammation.

Improving lifestyle aids depressed obese peopleA meta-analysis of 31 past studies showed that a lifestyle modification approach on weight loss, including diet counseling, improved participants' mood the most, while obesity medication treatments did not have an effect. The number of pounds shed by participants was not linked to changes in mood, and the effect of weight loss on mood is still unclear, an expert said. Researchers emphasized that the study was not indicating weight loss on its own was the only needed treatment for obese patients diagnosed with clinical depression. Reuters (3/7)
Scientists develop new body-fat scaleU.S. scientists have developed a new body-fat index called the Body Adiposity Index that uses a hip-circumference-to-height ratio instead of weight and height used in BMI. BAI tests conducted in two population studies suggested that different ethnic groups can use the index. However, "it remains to be seen if the BAI is a more useful predictor of health outcome" than BMI or other measures, scientists said. The Vancouver Sun (British Columbia)/Reuters (3/3)

Scientists study gut microbes' effect on metabolism, weightResearchers are investigating how the diverse community of microbes in the intestines affect metabolism and weight, but caution that it's too early to create bacteria-laden products for weight loss. They say that people pick up different bacteria from their environments, and babies collect bacteria mainly from their mothers and others around them, which may mean that the risk for obesity could be passed this way. Los Angeles Times (6/21)
Plant-based diet lowers colon cancer risk for men, womenA diet based on fruits, vegetables and low-fat dairy reduced the risk of colon cancer by 65% in women, study data showed.

Study hints at "dark side of hope" with illnessA study found that patients told their colostomies were permanent got on with their lives and actually were happier than those told the procedure could be reversed in six months. "We're not saying hope is a bad thing. What we're pointing out is that there can be a dark side of hope. It can cause people to put their lives on hold. Instead of moving on and trying to make the best of circumstances, you can think, 'my circumstances are going to change eventually -- no point in dealing with these circumstances,'" said Dr. Peter A. Ubel, a study co-author. ABC News/Reuters (11/3)
More fussy babies diagnosed with acid reflux diagnosisMore doctors are diagnosing some fussy infants with gastroesophageal reflux disease, which experts say may be driven in part by research showing prescription medications, such as proton pump inhibitors, can be safe and effective in children.
