A high-fat diet could promote the development of Alzheimer's
Quebec City, October 28, 2008—A team of Université Laval researchers has shown that the main neurological markers for Alzheimer's disease are exacerbated in the brains of mice fed a diet rich in animal fat and poor in omega-3s. Details of the study—which suggests that diets typical of most industrialized countries promote the development of Alzheimer's—are outlined in the latest online edition of Neurobiology of Aging.
New study reveals higher protein breakfast may help dieters stay on track
Lafayette, Ind. (September 3, 2008) – A new study published online today in the British Journal of Nutrition found that timing of dietary protein intake affects feelings of fullness throughout the day. The study concluded that when people ate high-quality protein foods, from sources such as eggs and lean Canadian bacon, for breakfast they had a greater sense of sustained fullness throughout the day compared to when more protein was eaten at lunch or dinner.i
"There is a growing body of research which supports eating high-quality protein foods when dieting to maintain a sense of fullness," said Wayne W. Campbell, PhD, study author and professor of Foods and Nutrition at Purdue University. "This study is particularly unique in that it looked at the timing of protein intake and reveals that when you consume more protein may be a critical piece of the equation."
Issues on cholesterol: Diet, statins and genetics
Conversely, lifestyle, diabetes, dyslipidemia, cigarette smoking and hypertension contribute to most of the population-attributable risk in the large, international INTERHEART study of acute myocardial infarction (heart attacks). The identification of single gene disorders may pave the way to a better understanding of complex metabolic pathways. Understanding the genes that regulate high density lipoprotein (HDL) metabolism may lead to novel therapeutic approaches. This has been emphasized by two therapeutic approaches for the treatment of CAD:
- The infusion of apo AI containing proteoliposomes, using wild-type or a mutant form of apo AI, apo AIMilano, in patients with acute coronary syndromes;
- The long-term treatment of subjects with low HDL-C with the cholesteryl ester transfer protein (CETP) inhibitor Torcertapib. While Torcetrapib proved to have off-target toxic effects, two other CETP inhibitors (Anacetrapib and Delcetrapib) are being tested clinically. Experimentally, however, CETP inhibitors may not reduce atherosclerosis
Novel therapeutic approaches using agonists of the LxR/RxR pathway to up-regulate the ABCA1 transporter, or the transcriptional regulation of apo AI, are being explored.
Childhood dairy intake may improve adolescent bone health
Cincinnati, OH, August 13, 2008—Dairy is recognized as a key component of a healthy, balanced diet. However, until recently it was unclear how long-term dairy intake contributes to the many aspects of bone health in children, including bone density, bone mineral content, and bone area. A new study soon to be published in The Journal of Pediatrics investigates the effect of childhood dairy intake on adolescent bone health.
