(PhysOrg.com) -- Restricting daily calorie intake is a common plan to help obese and overweight people slim down to healthier weights. But the regime requires a daily 15 to 40 percent calorie reduction, which makes sticking to the diet hard for many. http://www.physorg.com/news176581605.html Medicine & Health Wed, 04 Nov 2009 18:40:02 EST news176581605 One hundred years ago, Kikunae Ikeda discovered the flavour-giving properties of glutamate, a non essential amino acid traditionally used to enhance the taste of many fermented or ripe foods, such as ripe tomatoes or cheese. New research now reveals that the tongue has a receptor that is exclusively activated by glutamate. http://www.physorg.com/news174301682.html Medicine & Health Fri, 09 Oct 2009 10:17:25 EST news174301682 An important analysis conducted by Children's Hospital Oakland Research Institute scientists suggests the importance of ensuring optimal dietary intakes of vitamin K to prevent age-related conditions such as bone fragility, arterial and kidney calcification, cardiovascular disease, and possibly cancer (1). Vitamin K is concentrated in dark green plants such as spinach or Swiss chard, and is either not present or present in only small amounts in most multivitamin pills. http://www.physorg.com/news172412503.html Medicine & Health Thu, 17 Sep 2009 13:22:16 EST news172412503 A difference in brain activity patterns may explain why some people are able to maintain a significant weight loss while others regain the weight, according to a new study by researchers with The Miriam Hospital. http://www.physorg.com/news172229784.html Medicine & Health Tue, 15 Sep 2009 10:50:01 EST news172229784 (PhysOrg.com) -- Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens -- and what to do about it. http://www.physorg.com/news171884331.html Medicine & Health Fri, 11 Sep 2009 10:50:01 EST news171884331 The risk of becoming obese is 2.5 times higher for those who have double copies of the best known risk gene for overweight and obesity. However, this is only true if the fat consumption is high. A low fat diet neutralizes the harmful effects of the gene. http://www.physorg.com/news171869176.html Medicine & Health Fri, 11 Sep 2009 06:28:58 EST news171869176 (PhysOrg.com) -- Faculty of Life Sciences at University of Copenhagen shows that vitamin C deficiency may impair the mental development of new-born babies. http://www.physorg.com/news171115070.html Medicine & Health Wed, 02 Sep 2009 13:10:01 EST news171115070 A new study published in the International Journal of Obesity reports that consumption of sugar-free beverages sweetened with low-calorie sweeteners increases dietary restraint, a key aspect of successful weight maintenance. http://www.physorg.com/news170328540.html Medicine & Health Mon, 24 Aug 2009 10:40:02 EST news170328540 A Michigan State University researcher is challenging health standards that consider nitrates and nitrites in food to be harmful. http://www.physorg.com/news170011503.html Medicine & Health Thu, 20 Aug 2009 20:30:01 EST news170011503 Breast cancer is the 7th leading cause of mortality in the United States and results in approximately 41,000 deaths each year. Although genetic factors are important, there is considerable evidence that breast cancer risk is related to modifiable lifestyle factors, such as physical activity, body weight, alcohol intake, and dietary choices. The September 2009 issue of The American Journal of Clinical Nutrition reports the results of 3 human studies designed to better delineate the relation between animal foods and breast cancer risk. http://www.physorg.com/news169472896.html Medicine & Health Fri, 14 Aug 2009 13:02:44 EST news169472896 A new study of childhood obesity in the United States has found that some social factors, such as the presence of friends, may put overweight youths at greater risk of overeating. http://www.physorg.com/news168536392.html Medicine & Health Mon, 03 Aug 2009 16:40:23 EST news168536392 Experts estimate that over 24 million people worldwide suffer from dementia, and many of these people live in low- and middle-income countries.

Researchers in Australia found that drinking fat free milk in the morning helped increase satiety, or a feeling of fullness, and led to decreased calorie intake at the next meal, as compared with a fruit drink. The milk drinkers ate about 50 fewer calories (or nearly 9% less food) at lunch. http://www.physorg.com/news164878577.html Medicine & Health Mon, 22 Jun 2009 08:40:01 EST news164878577 The beta-carotene in so-called "Golden Rice" converts to vitamin A in humans, according to researchers at Baylor College of Medicine and Tufts University in an article that appears in the current issue of the American Journal of Clinical Nutrition. http://www.physorg.com/news161441355.html Medicine & Health Wed, 13 May 2009 13:49:48 EST news161441355 (PhysOrg.com) -- A new study has found that keeping the diet for type 2 diabetes under control gets a lot of help from including daily amounts of foods with the right kind of fats such as walnuts. http://www.physorg.com/news160765693.html Medicine & Health Tue, 05 May 2009 18:09:03 EST news160765693 Breast-fed babies grow more slowly than formula-fed babies, which is why new growth charts, based solely on the growth patterns of breast fed babies, are being introduced in the UK in May. This slower pattern of growth in the first year of life is possibly one reason why breast-fed babies are less likely to become overweight children later on. http://www.physorg.com/news159699110.html Medicine & Health Thu, 23 Apr 2009 09:52:25 EST news159699110 Liwei Chen, MD, PhD, Assistant Professor of Epidemiology at the LSU Health Sciences Center New Orleans School of Public Health, is the lead author of a research paper showing that weight gain and obesity are more linked to an increase in liquid calories, particularly sugar-sweetened beverages, than calories from solid food. To our knowledge, this is the first study to document the relative effects of calories from liquids compared with those of calories from solid food on weight loss in adults over an extended period. The study is published in the May 1, 2009 issue of the American Journal of Clinical Nutrition. http://www.physorg.com/news159632501.html Medicine & Health Wed, 22 Apr 2009 15:22:09 EST news159632501 In an epidemiological study of men and post-menopausal women primarily over 60 years of age, regular moderate alcohol intake was associated with greater bone mineral density (BMD). Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University found associations were strongest for beer and wine and, importantly, BMD was significantly lower in men drinking more than two servings of liquor per day. The results suggest that regular moderate consumption of beer or wine may have protective effects on bone, but that heavy drinking may contribute to bone loss. http://www.physorg.com/news155305089.html Medicine & Health Tue, 03 Mar 2009 12:18:53 EST news155305089 (PhysOrg.com) -- Pre-school children who watch a lot of television are considerably fatter than those who don`t, according to a major new study. http://www.physorg.com/news154884377.html Medicine & Health Thu, 26 Feb 2009 15:27:00 EST news154884377 The availability of healthy food choices and your quality of diet is associated with where you live, according to two studies conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. Researchers examined healthy food availability and diet quality among Baltimore City and Baltimore County, Md., residents and found that availability of healthy foods was associated with quality of diet and 46 percent of lower-income neighborhoods had a low availability of healthy foods. The results are published in the March 2009 issue of the American Journal of Clinical Nutrition and the December 2008 issue of the American Journal of Preventive Medicine. http://www.physorg.com/news154789556.html Medicine & Health Wed, 25 Feb 2009 13:06:39 EST news154789556 A new study published in the March 2009 American Journal of Clinical Nutrition by Marek Naruszewicz and colleagues from Poland suggests that acrylamide from foods may increase the risk of heart disease.
