NAFLD occurs in patients with obesity and type II diabetes and is being seen at younger ages in association with the obesity epidemic. NAFLD is characterized by excessive accumulation of fat in the liver. In a proportion of NAFLD cases, liver pathology progresses to hepatitis, fibrosis and liver cancer. http://medicalxpress.com/news/2013-04-dietary-medium-chain-triglycerides-nonalcoholic.html Diseases, Conditions, Syndromes Wed, 24 Apr 2013 15:46:46 EST news286037198 Kids are consuming fewer calories, and adults are eating less fast food, according to a federal government survey released Feb. 21. http://medicalxpress.com/news/2013-03-kinesiology-expert-comments-latest-federal.html Health Mon, 04 Mar 2013 07:40:03 EST news281604340 (HealthDay)—Eating out can lead to weight gain and increase people's risk for heart disease, diabetes and other serious health issues because popular menu items often have more fat, calories and saturated fat than meals typically prepared at home. http://medicalxpress.com/news/2013-03-heart-health-expert.html Cardiology Fri, 01 Mar 2013 13:28:26 EST news281366890 New research is challenging widely held beliefs about the dietary benefits of unsaturated fats, showing that some types long considered healthy, such as corn and safflower oil, may actually harm people with heart problems. http://medicalxpress.com/news/2013-02-omega-fats-pose-dangers.html Health Fri, 22 Feb 2013 12:50:01 EST news280757112 Dietary advice about fats and the risk of heart disease is called into question in BMJ today as a clinical trial shows that replacing saturated animal fats with omega-6 polyunsaturated vegetable fats is linked to an increased risk of death among patients with heart disease. http://medicalxpress.com/news/2013-02-dietary-fats-heart-disease-guidance.html Cardiology Tue, 05 Feb 2013 18:30:01 EST news279305891 A study by researchers at the Institute for Aging Research (IFAR) at Hebrew SeniorLife, an affiliate of Harvard Medical School (HMS), has found that dairy intake —specifically milk and yogurt —is associated with higher bone mineral density (BMD) in the hip, but not the spine.

The analysis is based on the characterization of the lipid component of the cells, which is indicative of malignancy. This has allowed the researchers to develop a classifier to discriminate cells capable of inducing metastasis.

The findings establish a "new" link between diet and atherosclerosis and suggest a novel way to prevent cardiovascular heart disease.

The study investigated the effect of dietary fat (classified as total, saturated, monounsaturated, polyunsaturated, omega 6, omega 3 and trans) on a range of preclinical and clinical outcomes in women having IVF. Results showed that the intake of saturated fat was inversely related to the number of mature oocytes retrieved, while polyunsaturated fat consumption was inversely associated with early embryo quality.(1) http://medicalxpress.com/news/2012-07-high-intake-dietary-fats-birth.html Other Tue, 03 Jul 2012 04:20:01 EST news260507187 The vegetables in salads are chock-full of important vitamins and nutrients, but you won't get much benefit without the right type and amount of salad dressing, a Purdue University study shows. http://medicalxpress.com/news/2012-06-no-fat-low-fat-dont-nutrients-salads.html Health Tue, 19 Jun 2012 15:22:59 EST news259338047 Certain saturated fats that are common in the modern Western diet can initiate a chain of events leading to complex immune disorders such as inflammatory bowel diseases (IBD) in people with a genetic predisposition, according to a study to be published early online in the journal Nature. http://medicalxpress.com/news/2012-06-western-diet-gut-bacteria-triggers.html Medical research Wed, 13 Jun 2012 13:00:01 EST news258810652 Simply ejecting your rear from the couch means your hand will spend less time digging into a bag of chocolate chip cookies. http://medicalxpress.com/news/2012-05-couch-equals-cookies-simple-health.html Health Mon, 28 May 2012 16:00:17 EST news257416458 It has been known for years that eating too many foods containing "bad" fats, such as saturated fats or trans fats, isn't healthy for your heart. However, according to new research from Brigham and Women's Hospital (BWH), one "bad" fat—saturated fat—was found to be associated with worse overall cognitive function and memory in women over time. By contrast, a "good" fat—mono-unsaturated fat was associated with better overall cognitive function and memory. http://medicalxpress.com/news/2012-05-fat-good-bad-heart-brain.html Neuroscience Fri, 18 May 2012 00:00:01 EST news256493427
