Regular Use of High-Heeled Shoes Changes Mechanics of Walking

High-heeled shoes are a fashion statement for many women. They define the calf muscle, make legs appear longer, and cause the buttocks to protrude slightly. While most women who wear high-heeled shoes know that they’re not the most supportive footwear option, a new study shows that they have a much more profound effect than previously thought. Published in the Journal of Applied Physiology, a recent study shows that high-heeled shoes change the mechanics of walking in a habitual user, even when the user is walking barefoot [1].

Lowering Physical Activity Impairs Glycemic Control, Even in Healthy People

Low levels of physical activity — like the 5,000 steps per day that Americans typically achieve, which is only about half of the recommended amount — have been implicated in the development of insulin resistance and its progression to full blown type 2 diabetes. However, the studies that suggested this connection were performed under laboratory conditions; they did not use people eating real meals, and they did not assess glycemic variability, so the direct impact of physical activity on glycemic control is not completely clear.

Elevated postprandial glucose (PPG) often precedes the development of type 2 diabetes, and is a risk factor for adverse cardiovascular events, independently of diabetes status. Thus, Dr. Catherine Mikus and her colleagues at the University of Missouri set out to precisely define the impact of reducing physical activity on PPG and glycemic variability in healthy, active volunteers as they went about their daily lives. The results of their study were recently published in the journal Medicine and Science in Sports and Exercise [1].

My Plate Replaces Food Pyramid to Help Consumers Eat Better

Last month, First Lady Michelle Obama and Agriculture Secretary Tom Vilsack unveiled the federal government’s new food icon, MyPlate. MyPlate is a new generation icon with the intent to prompt consumers to think about building a healthy plate at meal times. The new icon will replace the MyPyramid image as the government’s primary food group symbol as an easy-to-understand visual cue to help consumers adopt healthy eating habits consistent with the 2010 Dietary Guidelines for Americans [1].

New Website, Videos Provide Important Diabetes Resources

New videos to help people make lifestyle changes and cope with the demands of diabetes were announced by the U.S. Department of Health and Human Services’ National Diabetes Education Program (NDEP). The series of three-to five-minute videos, which can be found at www.YourDiabetesInfo.org/HealthSense, address topics such as setting goals to improve health, living with diabetes, finding the support you need, as well as segments on diabetes prevention and physical activity.

The Review Is In: Lifestyle Changes Prevent Breast Cancer

This article was written by Allison Bland.

Experts agree that diet and nutrition can reduce risk of many diseases, including different types of cancer and chronic disease. A recent update to a 2007 report by the American Institute for Cancer Research/World Cancer Research Fund (AICR/WCRF) concludes that breast cancer deaths can be prevented by physical activity, breast feeding, a healthy diet and other preventative measures. The study is an update to the breast cancer chapter of Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective [1]. Earlier conclusions were based on data from 873 studies evaluating the relationship between diet, physical activity, obesity and cancer [2]. The 2009 update includes evidence from an additional 81 studies.
