Wired to Ignore Warning Signs

1 Older Brains Too Trusting, Invite Fraud

Elderly adults aged 80 to 89 are the primary victims of fraud, losing nearly $3 billion a year to scam artists. Up to now it was widely assumed that this was because of diminished brain function and advancing senility, but new research indicates that older brains simply process visual cues differently. Specifically, persons aged 55 to 84, asked to rate photographs of faces for trustworthiness, failed to notice facial and upper body cues that are known to indicate deceitfulness, and which were spotted by a control group in their 20s. MRI tests revealed that an area of the brain called the anterior insula became far more active in the young group. Researchers suggest that this reflects older brains focusing on good feelings rather than negativity, and not decreased mental function.

From Reality TV to Real Life

2 New Diagnosis for Hoarders

Hoarding, a psychological condition which has received national attention from reality TV shows, has been associated with Obsessive-Compulsive Disorder, until now. In the new edition of the American Psychiatric Assn.'s Diagnostic and Statistical Manual of Mental Disorders (DSM), set to publish in May, hoarding disorder, characterized by a "persistent difficulty discarding or parting with possessions, regardless of their actual value,” becomes a separate diagnosis which, experts say, will result in more people having access to treatment. “Once it shows up in DSM, there will be much more pressure on clinicians to train in how to treat this problem," says Randy Frost, professor of psychology, Smith College. About 4 million Americans are hoarders, 90% of whom don’t recognize the problem.

Waiting for Results

3 Meat Producers to Test and Hold

Meat producers will soon be required to "test and hold" before shipping meat. Beginning next year, meat producers in the U.S. will follow the new rule aimed at helping to prevent foodbourne illnesses resulting from bacteria in meat and poultry. The rule will mean that producers of "non-intact" beef and ready-to-eat products with meat must wait for test results before shipping. Currently, companies are only asked, not required, to wait for test results after samples are collected by the USDA. That policy resulted in outbreaks of foodbourne illness from E. coli, salmonella and listeria. MSNBC reports that if the new rule had been in place between 2007 and 2010, 49 of the 251 meat, poultry and processed egg product recalls would have been prevented.

Calorie Zapper!

4 Brown Fat Transplants May Aid Weight Loss

Brown fat transplanted in the gut may lead to weight loss, say researchers who found that mice given brown fat transplants lost weight. Scientists conducted their research with mice to help determine whether adding more brown fat could help to jump-start metabolism, and the results were dramatic. Researchers also found that mice on high fat diets who had brown fat transplants were able to avoid metabolic changes that lead to type 2 diabetes. WebMD reports that people carry tiny deposits of brown fat near the collarbones, along the spine, between the shoulder blades and around the heart. Brown fat burns calories and helps keep the body warm, but white fat stores calories. People have mostly white fat! The research was published in Journal of Clinical Investigation.

Brightly Colored Are Best

5 Fruit and Vegetable Nutrients Cut Cancer Risk

Eating plenty of fruits and vegetables can reduce a woman’s risk for breast cancer, especially ER-negative cancers which are more aggressive and tend to have a poorer prognosis. Researchers publishing in the Journal of the National Cancer Institute have found that women whose blood carried higher levels of carotenoids, such as alpha- and beta-carotene, lutein+zeaxanthin, and lycopene have a significantly lower risk of developing breast cancer. Carotenoids are yellow, orange and red pigments found in plants so the nutrients are found in fruits and vegetables such as carrots, winter squash, sweet potatoes, and tomatoes. Dark leafy greens such as spinach and kale are also rich in carotenoids. A woman may be able to increase carotenoid absorption by adding small amounts of fat to the diet.
