| Diners eat less when menus display exercise required to burn off the meal Posted: 25 Apr 2013 04:11 AM PDT AUSTIN, April 25 — Restaurants with menus displaying how much exercise is required to burn off the meal may help people eat less and make healthier choices, a new study finds.
"We need a more effective strategy to encourage people to order and consume fewer calories from restaurant menus," said senior researcher Dr. Meena Shah. "Brisk walking is something nearly everyone can relate to, which is why we displayed on the menu the minutes of brisk walking needed to burn food calories," added lead researcher Ashlei James. The research included 300 people, aged 18 to 30, who were randomly assigned to be given a menu without calorie labels, a menu with calorie labels, or a menu with labels for the minutes of brisk walking needed to burn off the calories in the food. Typical menu items included burgers, chicken sandwiches, salad, fries, desserts, soda, and water. An example of the information on the menu was that a woman would need to walk briskly for two hours to burn off the calories in a double cheeseburger, the researchers said. The people given the menu listing the minutes of exercise ordered and consumed fewer calories than those given the other menus. However, there was no difference in the number of calories ordered and consumed between the subjects who ordered from the other two menus, the ones with and without calorie labels. Results from the study were presented April 23 at the Experimental Biology 2013 meeting in Boston. — AFP/Relaxnews |
| Mushrooms can be an effective source of vitamin D Posted: 25 Apr 2013 02:51 AM PDT BOSTON, April 25 — Tucking into a bowl of cream of mushroom soup or a plate of sauteed mushrooms may be an effective way of upping your vitamin D intake, provided you choose mushrooms that have been exposed to plenty of UV light, suggest the authors of a new US study.
Doses all measured 2,000 International Units (IUs). Vitamin D is crucial for building strong bones and muscle strength, and helps reduce the risk of fracture and osteoporosis. It's been shown to help fight infections like the flu and to play a role in fighting cancer, cardiovascular disease, depression and diabetes. After 12 weeks, researchers found no difference in the vitamin D levels among participants who took supplements versus those who ingested the mushroom powder. "These results provide evidence that ingesting mushrooms which have been exposed to ultraviolet light and contain vitamin D2, are a good source of vitamin D that can improve the vitamin D status of healthy adults," said lead author Michael Holick in a statement. The findings were published in the journal Dermato-Endocrinology and presented Monday at the American Society for Biochemistry and Microbiology annual meeting in Boston. It's been a good week for the fungi, as another study released this week out of John Hopkins Bloomberg School of Public Health concluded that swapping out meat for mushrooms in one meal a day helped subjects lose weight, reduce overall body fat and maintain their weight loss over time. — AFP/Relaxnews |
