Although short-term studies suggest that switching from sugar to calorie-free sweeteners can help people lose weight, the December 2011 Harvard Health Letter explores the possibility that it may actually promote weight gain. Use of super-sweet artificial sweeteners may desensitize users to sweetness. Healthful foods like fruits and vegetables may become unappetizing by comparison. As a result, the overall quality of the diet may decline. The calories removed from the diet by the sugar-for-sweetener swap may sneak back in, in the form of refined carbohydrates and low-quality fats. Another concern is that artificial sweeteners could cause weight gain by directly stimulating the development of new fat cells.

In the movie “Wedding Crashers,” Owen Wilson and Vince Vaughn made party crashing seem like harmless fun. A different sort of party crasher—microbes with names like Campylobacter and Salmonella (pictured to the right)—sicken nearly 50 million Americans each year. Holiday buffets and dinners are a more inviting setting for the microbes that cause food poisoning [...]
Family and togetherness are key themes for the holidays. That can make the holidays awfully difficult for people who are grieving the loss of a loved one. My father passed away a month before the holidays. We still shared presents, ate large meals, visited with friends, even sang carols—but it was all pretty subdued. “If [...]
The new science of social networks is demonstrating how personal interconnections can affect our health. Ideas and habits that influence health for better or for worse can spread through social networks in much the same way that germs spread through communities. An article in the December issue of the Harvard Men’s Health Watch explores how social networks can affect weight and mood. A study of people taking part in the Framingham Heart Study found that among participants who had a friend become obese, their chance of becoming obese rose by 57%. A different study from Framingham showed that happiness can also spread across social networks. Research into social networks could help experts some day use them to improve public health.
With Veterans Day and Halloween behind us, we are moving full steam ahead to the holidays, the stretch from Thanksgiving to New Year’s Day (or Super Bowl Sunday, depending on your perspective). The holidays can be a wonderful time, full of friends, family, and fun. But they can also generate pressures and situations that undermine health. To help you enjoy a healthy and happy holiday season, Harvard Health Publications is offering three Special Health Reports that focus on common holiday challenges: depression, overuse of alcohol, and healthy eating.

Crisp autumn weather, flickering jack-o-lanterns, costumed children trick-or-treating—and a good fright or two—make for a great Halloween. What is it about getting scared by a haunted house, a roller coaster, or a bungee jump that some people find exhilarating and others find downright frightening? It could be how you are wired, writes Dr. Robert Shmerling [...]
