Happy Marriage, Happy Heart
Happily married people have lower blood pressure(51)unhappily married people or singles, a Brigham Young University study says.
On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily(52) . people, according to the study.
"There seem to be some unique health benefits from marriage. It's not just being married(53)benefits health - what's really the most protective of health is having a happy(54) ," study author Julianne Holt-Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.
The study included 204 married and 99(55)adults who wore portable blood-pressure monitors for 24 hours. The(56)recorded blood pressure at random intervals" and provided a total of about 72 readings.
"We wanted to capture participants' blood pressure doing whatever they normally(57)in everyday life. Getting one or two readings in a clinic is not really(58)of the fluctuations that occur throughout the day,"4 Holt-Lunstad said.
Overall, happily married people scored four points(59)on the blood pressure readings than single adults. The study also found that blood(60)among married people -- especially those in happy marriages-(61)more during sleep than in single people.
"Research has shown that people whose blood pressure remains high throughout the night are at(62)greater risk of heart disease than people whose blood pressure drops," Holt-Lunstad said.
The study was published in the March 20(63)of the journal Annals of Behavioral Medicine.
The study also found that unhappily married 'adults have higher blood pressure than(64)happily married and single adults.
Holt-Lunstad noted that married couples can encourage healthy habits in one(65) , such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said.

Red Meat Links to Higher Risk of Breast Cancer
Exercise and keeping a healthy weight are two things that doctors say might help women lower their risk of breast cancer.
Mothers may reduce their risk if they breastfeed for at least four months. For older women, hormone replacement therapy can lower the risk of some other diseases. But it has been found to increase the risk of breast cancer. So women should consider their choices carefully. The same may be said for diet.
New findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone-receptor positive. The growth is fed by the levels of estrogen or another hormone, progesterone, in the body.
Researchers at Brigham Women's Hospital in Boston, Massachusetts, reported the findings as part of a health study of nurses. The researchers followed the health of more than 90,000 women from 1991 to 2003. Those who ate the most red meat ate more than one and one-half servings a day. A serving was defined as roughly 84 grams. Those who ate the least red meat ate less than three servings a week. This is what the study found about breast cancers that were hormone receptor-positive: The women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it.
Eunyoung Cho, the lead author of the report, says more research is needed to know the reason for the link. But in the past, researchers have suggested that three things may play a part. One is the way meat is cooked or processed. Another is the use of growth hormones in cows. And the third is the kind of iron in red meat. The study appears in the Archives of Internal Medicine.
And now we have more to tell you about our subject -- resveratrol. We discussed a study in the United States that found that large amounts of this plant compound helped fat mice live longer. The mice were fed much more resveratrol than people could get from red wine, one of the foods that contains it.
Now, scientists in France say resveratrol also improves muscle performance -- again, at least in mice. They were able to run two times as far in laboratory treadmill tests4 as mice normally could. The study at the Institute of Genetics and Molecular and Cellular Biologys appeared in the journal Cell.
Breastfeeding helps women prevent the development of breast cancer to a certain degree.
