Fat-Altered Brain May Favor Fats

1 High-Fat Diet Could Lead to Brain Scarring

A study published recently in The Journal of Clinical Investigation indicates that a diet of high-fat foods may result in gliosis, a process that produces scarring of the central nervous system and damage to the hypothalamus, which controls human hunger and other natural rhythms. Although the research involved rats, it raises the possibility that diet can alter the brain's very structure, and can do so very quickly: rodents exhibited signs of neuron injury after just three days of high-fat intake. Researchers believe that a long-term fatty diet may produce permanent neural damage which could re-program the brain to favor obesity and make it more difficult for the obese to lose weight or control their eating behavior.

It’s The Antioxidants

2 Grapes May Prevent Age-Related Blindness

Antioxidants in grapes may help prevent the onset of age-related macular degeneration, a debilitating condition that is the leading cause of blindness in the elderly. Researchers studied how an antioxidant-rich diet affected damage to the retinas of mice prone to developing retinal damage in old age. "The protective effect of the grapes in this study was remarkable, offering a benefit for vision at old age even if grapes were consumed only at a young age," says lead investigator Silvia Finnemann, PhD, Fordham University. "Preserving eye health is a key concern as we age and this study shows that grapes may play a critical role in achieving this," says Kathleen Nave, president of the California Table Grape Commission. The study is published in Free Radical Biology and Medicine.

It's Normal Too, Say Moms

3 Moms Want Breast-Feeding on Sesame Street

"Bring Breastfeeding Back to Sesame Street," is a popular petition supported by mothers on Care2.com. Breast-feeding was shown on the show in the 70s and 80s. The mothers want breast-feeding to be "normalized again," reports MSNBC. The petition has more than 10,000 signatures. Mothers don't want to stop Sesame Street from showing bottle feeding, but they would like to see both options represented. In an email response, Sesame Street creators indicated that they don't have a mandate opposing breast-feeding, and would portray it again if it fit naturally in a storyline. The show's creators also said that each new season is "designed to teach a specific curriculum." This year, the curriculum is technology, science, engineering and math. Breast-feeding seems so simple in comparison!

Happy Workers Are Healthier

4 Boredom Leads to Overeating, Drinking Alcohol

Are you bored at work? A recent British survey suggests that 25 percent of office workers are affected by chronic boredom and that this causes them to eat chocolate, drink more coffee, and imbibe in after-hours alcohol. Obviously these habits could have effects on physical health, which could in turn reduce productivity and increase health insurance costs. Additionally, workers who were bored consistently lose concentration and make more mistakes on the job. Researchers suggest strategies for employers such as job rotation, enrichment programs and provisions of healthier choices within the workplace. The research from the University of Central Lancashire will be presented this week at a meeting of the British Psychological Society’s Division of Occupational Psychology.

Affects First Two Trimesters

5 Some Chemicals Tied to Miscarriages in Nurses

Results from a study conducted by the National Institute for Occupational Health and Safety (NIOSH) shows that female nurses exposed to chemotherapy doubled their risk of miscarriage. Approximately 7500 nurses who were pregnant between 1993 and 2002 were asked about their exposure to chemotherapy drugs, anesthetics, disinfectant and x-rays. The miscarriage rate before in nurses exposed to chemotherapy drugs daily for over an hour was double that of the general population. X-rays exposure increased the risk by 30 percent and using disinfectants every day for more than an hour doubled the rate of second trimester miscarriages. Researchers were shocked that nurses were still being exposed to chemotherapy drugs during the first trimester because the risk of miscarriage is known.
