DEADLY EMOTIONS CAN SHORTEN YOUR LIFE

Thursday, June 3rd, 2010


We all know the type-the person who stands at the elevator door and jabs at the button three, four, even five times when the car fails to arrive quickly enough. In conversation, this individual finishes your sentences for you or glances constantly at the time. People like this feel that they’ve got the world to conquer. And you’re very cautious about what you do or say with them, because they can ignite like firecrackers into anger.
Thirty years ago, scientists first identified such individuals as exhibiting “Type A” behavior: in a hurry, impatient, often angry. They also found persons with “Type B” behavior: laid-back, calm, slow to anger, good listeners.
The researchers found that Type A’s more often fell victim to heart attacks; Type B’s less so. But the researchers could not figure out how the personality connected with biology. What was there about Type A behavior that killed you? They had no answer, then.
“We have strong evidence now that hostility alone damages the heart,” says Dr. Redford Williams. One of the researchers who helped pinpoint the destructive effects of hatred, Dr. Williams is a professor of psychiatry at Duke University Medical Center in Durham, North Carolina.
“It isn’t the impatience, the ambition, or the work drive,” Dr. Williams says. “It’s the anger. It sends your blood pressure skyrocketing. It provokes your body to create unhealthy chemicals. For hostile people, anger is a poison.”
Psychologists and psychiatrists have always told their patients to “let anger out” because, they said, if you hold it in, you can become depressed or develop ulcers. Dr. Williams gives quite another prescription: Avoid feeling angry in the first place, and you won’t need to suppress your anger.
Bruce T. Bowling, publisher of Fire-house magazine in New York City, clearly exhibited Type A behavior.
“I couldn’t catch up,” Mr. Bowling says. “I’d walk into my house, the Chinese food in one hand, mail in the other, scanning it as I went to the bathroom. I felt if I could do four things at the same time, I’d save time.”
Mr. Bowling meted out large doses of hostility to those around him. “Waitresses were never fast enough,” he says. “Taxi drivers drove me crazy. I would purposely under-tip them. New York City, I used to think, will do me in.”
In 1988, all his hostility took its toll. Just back from a firefighters’ convention, Mr. Bowling felt the classic pains in his shoulders, arms, and neck. At the hospital emergency room at 3 A.M., they told him: heart attack. He was lucky. He survived. Each year, half a million Americans don’t.
Dr. Meyer Friedman is a cardiologist at Mount Zion Hospital in San Francisco and one of the co-discoverers of Type A behavior. He contends that hostility, impatience, and anger powerfully affect your body. Dr. Williams, on the other hand, says you can be impatient with impunity, so long as it doesn’t lead to anger. It’s the anger that gets you. The issue is not settled, but more and more experts agree that both anger and hostility can be hazardous to your health.
Originally, Dr. Friedman and his collaborator, Dr. Ray Rosenman, identified three parts of the Type A behavior:
1.  Intense striving toward many poorly defined goals
2.  Preoccupation with time and an obsession with getting things done faster
3.  Free-floating hostility
To be hostile means that you want to hurt or punish somebody. Anger, Dr. Friedman says, can be the same thing or less – a feeling of displeasure toward yourself. Both hostility and anger rile your heart and body. To have “free-floating hostility” means that you are angry, or on the point of anger, much of the time, with or without major cause.

PLANNING FOR GOOD NUTRITION: FALLACIES AND FACTS ABOUT NUTRIENTS FOR ADULTS

Thursday, June 3rd, 2010


1. Fallacy. People over 50 years of age have much lower needs for protein, minerals, and vitamins than do younger adults.
Fact. The requirements for most nutrients are the same for adults of any age. Older people need fewer calories and so they must select foods with care to ensure adequate intake of protein, minerals, and vitamins.
2.   Fallacy. Milk and cheese are constipating, and therefore should be omitted by some older persons.
Fact. Milk and cheese are almost completely digested and leave little bulk. Constipation is corrected by including sufficient amounts of raw fruits and vegetables, whole-grain breads and cereals, and liquids, and not by the omission of milk and cheese.
3.   Fallacy. As long as the mother receives plenty of vitamins the fetus will receive all of its nutritional needs regardless of the mother’s nutritional status.
Fact. Vitamin supplements cannot make up for inadequate intakes of protein, calcium, iron, and other minerals. If the mother is poorly nourished, both mother and baby will be adversely affected.
4.   Fallacy. The obese pregnant woman should use a low calorie diet so that the baby will be small and delivery will be less difficult.
Fact. Calorie restriction and weight loss are not recommended during pregnancy. Small babies are at greater risk during the early months of life. Weight loss should be planned after the birth of the baby.
5.   Fallacy. Pregnant women should restrict their salt intake.
Fact. Pregnant women probably have higher requirements for sodium, and salt restriction can be dangerous. The pregnant woman should be allowed to salt her food to taste.
