Walking vs. Running to Lose Weight

“Want to lose weight? Then run, don’t walk,” reported U.S. News & World Report in the April 2013 issue.

When it comes to running vs. walking, the Lawrence Berkeley National Laboratory in California conducted a six year National Walkers’ and Runners’ Health Study. When they compared men and women who increased their walking or running, they found that running expended more energy than walking.

But people who choose to run may be different—they may be more physically fit, for example—than people who choose to walk.

Why Sitting is Bad (And How to Get Off Your Duff)

Sitting for hours on end can hurt more than your back end, say two studies.

British researchers tracked 153 younger and 725 older adults who all had risk factors for diabetes. Each participant wore an accelerometer to measure how much time he or she spent sedentary or engaged in moderate-to-vigorous exercise (like running or brisk walking) for at least a week. The results helped researchers hone in on why sitting is bad for people who are at risk for health problems such as diabetes.

Should You Drink Chocolate Milk After a Workout?

“Beverage of champions: Chocolate milk gets an Olympic-style makeover,” reported the Washington Post in January after ads featuring U.S. Olympic athletes began popping up during the Sochi winter games. Olympic athletes have access to the best in exercise regimens and health and nutrition advice. If they drink chocolate milk post workout, should you?

When it comes to recovering from intense exercise, this classic childhood beverage has taken the spotlight.

In some studies, drinking chocolate milk immediately after a strenuous workout is one of the best ways to recover quickly—better than sugary sports drinks like Gatorade. The milk’s naturally occurring sugar (lactose) is half glucose, its protein speeds up glycogen synthesis in the body, and its electrolytes (like potassium and, to a lesser extent, sodium) help you rehydrate.

How to Sanitize a Sponge: Are Your Kitchen Sponges Safe?

“Sponges are usually the dirtiest thing in the kitchen and difficult to keep clean,” says microbiologist Manan Sharma of the United States Department of Agriculture’s Food Safety Laboratory in Beltsville, Maryland

NSF International offers good reason to know how to sanitize a sponge; in a recent survey of U.S. homes they found 77 percent of the sponges and dish cloths contained coliform bacteria, 86 percent had yeast and mold, and 18 percent had Staph bacteria. NSF International is a non-profit agency that sets safety standards for water filters and other equipment.
