If healthier eating is on your list of resolutions for 2012, look no further. The January 2012 issue of the Harvard Women’s Health Watch offers 12 ways to break old dietary habits and build new ones.
For many years, nutrition research focused on the benefits and risks of single nutrients, such as cholesterol, saturated fat, and antioxidants. Today, many researchers are exploring the health effects of foods and eating patterns, acknowledging that there are many important interactions within and among nutrients in the foods we eat.
The result is a better understanding of what makes up a healthy eating plan. Here are five food- or meal-based ways to improve your diet that we list in the article (you can see all 12 on the Harvard Health website):
Pile on the vegetables and fruits. Their high fiber, mineral, and vitamin content make fruits and vegetables a critical component of any healthy diet. They’re also the source of beneficial plant chemicals not found in other foods or supplements.
Go for the good fats. Read more »

Why would a pediatrician draw blood from your 9-, 10-, or 11-year-old at his or her next annual wellness visit? Because the American Academy of Pediatrics (AAP) recently endorsed updated guidelines that call for checking LDL (bad) cholesterol levels in all kids between the ages of 9 and 11.
The cholesterol-test recommendation created quite a stir. But wait, there’s more. The guidelines also call for annual blood pressure checks beginning at age 3, and periodic blood sugar measurements starting between ages 9 to 11. There’s also a strong recommendation for kids and adolescents to limit sedentary screen time to two hours or less per day, and to get at least an hour a day of moderate physical activity.
The biological basis for these guidelines is that atherosclerosis (the fatty gunk in arteries that causes heart attacks, strokes, and other serious problems) starts during youth. In many cases, Read more »

When you sit quietly, your heart slips into the slower, steady pace known as your resting heart rate. A new study suggests that an increase in this rate over time may be a signal of heart trouble ahead.
Your heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.
Many factors influence resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow it down. (In his prime, champion cyclist Lance Armstrong had a resting heart rate of just 32 beats per minute.) Stress, medications, and medical conditions also influence the heart rate.
In today’s Journal of the American Medical Association, researchers from Norway report Read more »

The word “cancer” strikes fear in everyone who is told they have it. It conjures up images of a fast-moving, life-threatening disease.
That isn’t necessarily the case for men with newly diagnosed prostate cancer. More than half of them have a type of cancer that is confined to the prostate gland and that grows so slowly it will never affect their health or their lives. Yet almost 90% of men told they have prostate cancer opt for immediate treatment with surgery or radiation therapy—which often cause trouble getting or keeping an erection and an assortment of urinary problems.
Two weeks ago, a panel of experts convened by the National Institutes of Health recommended that many men with localized, low-risk prostate cancer be closely monitored, and that treatment be delayed until there was evidence that the disease was progressing.
“It’s clear that many men would benefit from delaying treatment,” Dr. Patricia A. Ganz, conference panel chairperson and director of the Division of Cancer Prevention and Control Research at the Jonsson Comprehensive Cancer Center at the University of California in Los Angeles, said in a statement, adding that Read more »

Do your neck and shoulders ache? Not long ago, you would have been told to rest, maybe use a neck brace, and wait until the pain had ebbed away. Doctors have changed their song about the best treatment for neck and shoulder pain. They now recommend movement instead of rest.
As described in Neck and Shoulder Pain, a newly updated Special Health Report from Harvard Health Publications, there is mounting scientific evidence for the role of stretching and muscle strengthening in treating people with neck and shoulder pain. After a whiplash injury, for example, people heal sooner and are less likely to develop chronic pain if they start gentle exercise as soon as possible. For those with long-term pain (called chronic pain), results from controlled studies show that exercise provides some relief.
One review of the research found that Read more »
