People with diets high in several vitamins or in omega 3 fatty acids are less likely to have the brain shrinkage associated with Alzheimer’s disease than people whose diets are not high in those nutrients, according to a new study published in the December 28, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology. The study author was Gene Bowman, ND, MPH, of Oregon Health & Science University in Portland, and a member of the American Academy of Neurology.
An intermittent, low-carbohydrate diet was superior to a standard, daily calorie-restricted diet for reducing weight and lowering blood levels of insulin, a cancer-promoting hormone, according to recent findings. Researchers at Genesis Prevention Center at University Hospital in South Manchester, England, found that restricting carbohydrates two days per week may be a better dietary approach than a standard, daily calorie-restricted diet for preventing breast cancer and other diseases, but they said further study is needed.
A healthy diet and the right amount of exercise are key players in treating and preventing obesity but we still know little about the relationship both factors have with each other. A new study now reveals that an increase in physical activity is linked to an improvement in diet quality. Many questions arise when trying to lose weight. Would it be better to start on a diet and then do exercise, or the other way around? And how much does one compensate the other?
A team of Johns Hopkins researchers has uncovered further evidence of the benefits of a balanced diet that replaces white bread and pasta carbohydrates with unsaturated fat from avocados, olive oil, and nuts — foods typical of the so-called “Mediterranean diet.” In a report prepared for the American Heart Association’s scientific sessions in Orlando next week, the Johns Hopkins investigators say swapping out certain foods can improve heart health in those at risk for cardiovascular disease, even if the dietary changes are not coupled with weight loss.
A recent study gauging the impact of consuming more fish oil showed a marked reduction both in inflammation and, surprisingly, in anxiety among a cohort of healthy young people. The research, supported by the Ohio State University Center for Clinical and Translational Science (CCTS), was conducted by a team of scientists that has spent more than three decades investigating links between psychological stress and immunity.
Drinking cherry juice significantly improves both the quality and duration of sleep, according to new findings from Northumbria University. Researchers from the School of Life Sciences have found that Montmorency cherry juice significantly increases the levels of melatonin in the body, the hormone which regulates sleep, and could benefit those who have difficulty sleeping due to insomnia, shift work or jet lag.
Healthier dietary choices by pregnant women are associated with reduced risks of birth defects, including neural tube defects and orofacial clefts, according to a study published Online First by the Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. The investigation was carried out by Suzan L. Carmichael, Ph.D., from Stanford University, Stanford, Calif., and colleagues.
A flurry of Internet sites are touting raw egg drinks or shakes as “primal and powerful,” with others suggesting uncooked eggs be blended with vanilla or avocado for a tasty, healthy snack and insisting that the connection between raw eggs and salmonella is a myth. Suzy Weems, Ph.D., a national food expert and chair of Baylor University’s family and consumer sciences department, has this word for health-seekers: Leave no egg uncooked.
The debate between good fat versus bad fat continues, as a new evidence review finds that a modified fat diet — and not a low fat diet — might be the real key to reducing one’s risk of heart disease. A low fat diet replaces saturated fat — such as or animal or dairy fat — with starchy foods, fruits and vegetables, while a modified fat diet replaces saturated fat with monounsaturated and polyunsaturated fats, found in foods such as liquid vegetable oils, fish, nuts, and seeds.
Living near fast-food restaurants appears related to an individual’s consumption of these foods whereas living near grocery stores and supermarkets appears generally unrelated to dietary quality, according to a report in the July 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The research was carried out by Janne Boone-Heinonen, Ph.D., from the University of North Carolina at Chapel Hill, and colleagues.
