Why tots shouldn’t watch TV

"Why tots shouldn’t watch TV
If you have a baby or a toddler, turn off that TV. A new study finds that when children are exposed to a lot of TV before the age of 2, they are deprived of interaction with adults, which can lead to delays in brain and language development. University of Washington researchers found that for every hour the TV set was on, even if it was just in the background, adults spoke from 500 to 1,000 fewer words to children. When the distraction of the boob tube was present, children spoke less, too, and there were fewer conversations between the adults and the children. This was true whether the show was a kid’s program or an adult show that parents were watching in the child’s presence. Speaking directly to a child, previous research has shown, is critical to brain development. In surveys, 30 percent of Americans admit to having the TV on all day long, whether anyone is watching or not. Television, researcher Dimitri Christakis tells LiveScience.com, “is a poor caregiver substitute. My recommendation is that children under the age of 2 be discouraged from watching television.”"

A Recipe For Longevity: 33 Of The Healthiest Foods On Earth"
"Is it possible to live to 125 or maybe 150? It's certainly a possibility, as discussed on Oprah Winfrey's recent show on longevity. She visited me at my farm to learn how, at 86, I am enjoying the robust health, energy, and mental creativity of someone many decades younger. My secret: large quantities of fruit and vegetables, plus an hour of daily exercise.
No pills, not even aspirin, and certainly no supplements ever enter my mouth -- everything I need comes from my fish-vegetarian diet, which incorporates 30-40 different kinds of fruit and vegetables every week. Even though I am Chairman and Owner of Dole Food Company, I do most of my own grocery shopping, and even took Oprah on an impromptu trip to Costco, in a day that included bike riding, exercise in the gym, and juicing vegetables in the kitchen. Oprah marveled at how much I eat, and yet never gain a pound. In fact, I expend a lot of energy in my 50-60 minutes of cardio and strength training every day. Plus there's the fact that fruit and vegetables tend to be lower in calories, but higher in filling fiber and other nutrients that help you feel satisfied.
By eating many fruits and vegetables in place of fast food and junk food, people could avoid obesity. Obesity accelerates aging even faster than smoking, according to scientific research.
We created the North Carolina Research Campus to study the health benefits of fruits and vegetables. It is the only campus in the world encompassing eight universities all working together for the benefit of health and longevity. These include Duke University, UNC Chapel Hill, NC State University, UNC Charlotte, North Carolina Central University, NC A&T State University, UNC Greensboro and Appalachian State University. We've gathered a comprehensive array of famous scientists and scientific equipment under one roof, including a two-story, 950 megahertz, 8-ton superconducting magnet. It is the largest and most powerful magnet in the world and will help us look at both plant and human cells at the most minute level.

Fight Disease With Soap and Water - Wash your hands
"Wall Street Journal, May 12, 2009
Put Up Your Dukes: Fighting Disease With Soap and Water
Fear of swine flu is fading, but there are still plenty of reasons to wash your hands frequently.
The list of infections that can spread via unwashed hands reads like the Biblical plagues, including staph, strep, salmonella, E. coli, hepatitis, MRSA (methicillin-resistant Staphylococcus aureus), colds, flu and norovirus -- the infamous cruise-ship bug.
The importance of hand washing has been known since 1847, when a doctor named Ignaz Semmelweis suspected that maternity patients were dying in his Vienna hospital because med students treated them right after working on cadavers. When he instituted hand-cleaning, the deaths fell sharply.
The Centers for Disease Control and Prevention says hand washing is the most effective way to stay healthy. But many people don't do it often enough, or long enough, to be effective. Here's a guide:
The swine flu headlines have brought attention to the importance of hand-washing. Health columnist Melinda Beck describes the best way to wash off germs and protect against sickness.
When to do it. Wash your hands every time you use the bathroom. Every surface presents an opportunity for germs to hitchhike out. "Who thinks to clean the latch on the inside of the stall door? Try nobody," says Jim Mann, executive director of the Handwashing for Life Institute, which advises food-service providers around the world on best hand-hygiene practices.
Also wash your hands whenever you change a diaper, pick up animal waste, sneeze, cough or blow your nose; when you take public transportation, insert or remove contact lenses, prepare food, handle garbage and before eating. Few people are as conscientious as they should be. Mr. Mann recalls being in meetings to discuss hand hygiene: "Everybody shakes hands. You finish the talk, and everybody runs for the food line. Nobody washes their hands."
How to do it. Soap and water is the gold standard. In a recent study in the journal Clinical Infectious Diseases, researchers in Australia doused the hands of 20 health-care workers with human H1N1 flu virus. Soap and water removed slightly more virus than three alcohol-based hand rubs. When volunteers didn't clean their hands, most of the virus was still present an hour after exposure.
It's the mechanical process of washing that's so effective. Soap molecules surround and lift the germs, friction from rubbing your hands loosens them, and water rinses them down the drain.
Experts recommend using warm water -- mainly for comfort, so you'll wash longer. Use liquid soap if possible. Bar soaps can harbor germs, though they'll likely rinse off with water.
Use enough soap to build a lather. Lace your fingers together to cover all the surfaces. Rub the fingertips of one hand into the palm of the other, then reverse. Keep rubbing for as long as it takes to sing "Happy Birthday" twice. (Some experts prefer "Row, Row, Row Your Boat." But any tune will do as long as it lasts at least 15 seconds.)
"The typical 'splash and dash' that most people do doesn't do anything," says Mr. Mann.
Rinse thoroughly. Residual soap can make hands sore. Leave the water on while you grab a paper towel and use it to shut off the faucet. Take it with you to use on the door handle as well.
Drying lessons. Many hand-hygiene experts are down on hand dryers -- chiefly because few people have the patience to dry completely and end up wiping their hands on their clothes. "That's fine -- unless your pants have been down around your ankles in the stall," Mr. Mann says.
Air dryers can also blow remaining germs as far as six feet away.
Antibacterial soap? In 2005, a Food and Drug Administration panel voted 11-to-1 that antibacterial soaps are no more effective at keeping people healthy than regular soap. There may be some downside too. Some antibacterial ingredients like triclosan leave a residue on the skin that continues killing some bacteria. Critics worry that the remaining bacteria could become resistant, not only to soap but also to antibiotics. "To our knowledge, it's not happened, but it's theoretically possible," says Elaine Larson, a professor in the schools of nursing and public health at Columbia University. Another problem with antibacterial soap, she says, is that it gives people a false sense of security. "People think, 'Ah -- it's antibacterial. So the germs are gone.' That's a false perception," Dr. Larson says.
Hand sanitizers. It's not often that a personal-care product gets a presidential endorsement. Some drug stores sold out after Barack Obama echoed the CDC's recommendation that people use alcohol-based hand sanitizers when soap and water aren't available to help stop the spread of swine flu.
Experts say they must be at least 60% alcohol to kill germs. "Alcohol ruptures their cell membranes -- it causes them to explode," says Dr. Larson, although she notes that if your hands are visibly dirty, soap and water is much preferable.
Curiously, the FDA does not allow over-the-counter hand sanitizers to claim they kill viruses. The CDC's recommendations are based on information published since the FDA ruling, showing that alcohol-based sanitizers are effective at killing viruses, specifically the H1N1 strain, says Nicole Coffin, a CDC spokeswoman.
Can you overdo handwashing? Yes. "Try to strike a balance between being obsessive-compulsive and being reasonable," says Dr. Larson. "And if there is some kind of outbreak like with the flu or SARS, then there is reason for more caution.""

Do Everybody a Favor: Take a Sick Day
By ANNE MARIE VALINOTI, M.D.
My patient was a 25-year-old man. He sat on the examination table, the picture of misery, coughing, red-eyed and shivering. His fever was 103. An interview and an examination suggested influenza (the rapid diagnostic test for flu wasn’t available at that time), but there was little I could offer him, other than ibuprofen and some homespun advice.
“Go home and get to bed,” I told him.
He looked at me. “Bed? I’ve got to get back to work.” He put on his jacket and power tie and headed back to Wall Street.
I was appalled. Work in that condition? How could he even think straight with that fever? Whom else would he infect along the way?
Still, a tiny part of me was filled with admiration. Here was a tough guy. No reason to let minor delirium keep him from doing his job.
I had recently finished my residency, three years immersed in the culture of house officer training. Of all the sins an intern or resident could commit, the worst was to call in sick, for it meant somebody else would have to do your work — extra patients to admit, phone calls to make, IVs to insert, emergencies to deal with.
As a resident, my greatest pride was in never having missed a day for illness. I’d drag myself in and sniffle and cough through the day. Once, I’m embarrassed to admit, I trudged up York Avenue to the hospital making use of my own personal motion sickness bag every few blocks while horrified pedestrians looked on.
Now, though, I see the foolishness of this bravura. And I confront it almost daily in my primary care practice. No one can miss a day — a minute, even — of work, carpooling, volunteering, vacation, anything. “I don’t have time to be sick!” my patients wail. Everyone must soldier on, leaving sick days to those with less important things to do.
And many patients aren’t satisfied with sympathy and friendly advice. They have come to the office for that little piece of blue paper, the antibiotic prescription. “I would never ask for this under normal circumstances,” I’m told — except (pick one) I’m getting married tomorrow; leaving for a month in the Amazon; having 25 houseguests for the weekend.
Never mind that antibiotics are useless in treating colds and viral illnesses, and that they have their own dangers and side effects. Some doctors will write the prescription just to get on with their day.
I have done this and know plenty of other physicians who have — much as we may resent being bullied and feel we’ve failed in our duty to “first, do no harm.” In fact, we may very well be doing harm. Beyond the possible side effects and allergic reactions, the nonchalant use of antibiotics in the community has helped lead to the rise of the drug-resistant bacteria known as superbugs.
“Clearly, the overprescribing of antibiotics in doctors’ offices, clinics and other community settings contributes to the problem of antibacterial drug resistance,” Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Disease, told me in an e-mail message. “Because most bacteria multiply rapidly, they can quickly evolve and develop resistance to antimicrobial drugs. Overusing or misusing antibiotics can make resistance develop even faster.”
If the swine flu epidemic ever swings into full gear, I will be prepared for the onslaught of ill patients. I will educate them about the appropriate use of antibiotics. I will provide symptomatic relief when I can. And I will let them know it’s O.K. to be sick. It’s O.K. to stay home from work, pull up the covers and drink gallons of hot tea all day. Maybe for an entire week.
And believe me: if you show up to work sick these days, you are not going to earn anyone’s admiration."

What Are Friends for? A Longer Life
"In the quest for better health, many people turn to doctors, self-help books or herbal supplements. But they overlook a powerful weapon that could help them fight illness and depression, speed recovery, slow aging and prolong life: their friends.
Researchers are only now starting to pay attention to the importance of friendship and social networks in overall health. A 10-year Australian study found that older people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk for obesity among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could promote brain health as we age.... in many studies, friendship has an even greater effect on health than a spouse or family member."

Why a Big Meal Makes You Hungry
"Every few months, a new study purports to prove that a calorie is a calorie is a calorie, and that the only way to lose weight is to burn more than you take in.
But veteran dieters know something that some researchers apparently don't: Certain foods seem to fuel the appetite like pouring gasoline on a fire. Some people find that once they start eating bread, cookies, chocolate, potato chips -- or leftover Easter candy -- they lose all sense of fullness and find it difficult to stop.
That's the concept behind "The Skinny," a new book by Louis J. Aronne, longtime director of the Comprehensive Weight Loss Program at NewYork Presbyterian Hospital/Weill Cornell Medical Center. He makes the best case yet why what you eat and when you eat it can make a big difference in appetite, satiety and how much willpower it takes to cut down. "It's true that a calorie is a calorie," Dr. Aronne says. "But what that doesn't take into account is how some calories affect what people eat later on."
Appetite Stokers
Some foods make it harder to stop eating:
- Bread
- Sweets
- Juice
- Pasta
- Wine or beer before dinner
- Artificial sweeteners

After 23 years of treating patients -- some of it espousing liquid diets -- Dr. Aronne has concluded that refined carbohydrates and foods with high sugar and fat content promote what he calls "fullness resistance." They interfere with the complex hormonal messages the body usually sends to the brain to signal that it's time to stop eating. People feel hungrier instead.This happens in part because refined carbohydrates raise blood-sugar levels, setting up an insulin surge that drives blood sugar down again, causing rebound hunger. That insulin spike also interferes with leptin, the hormone secreted by fat cells that should tell the body to stop eating. Obese people have loads of leptin, but it either doesn't get to the brain, or the brain becomes resistant to it. "This is not a failure of willpower, it's a physical mechanism," Dr. Aronne writes. The body also becomes resistant to insulin, setting the stage for diabetes.
Other researchers have described similar phenomena. An article in this month's Medical Hypothesis argues that for some people, refined foods with high sugar and carbohydrate content can be just as addictive as tobacco and alcohol.
Eating foods high in protein, vegetables, fiber and water have the opposite effect, Dr. Aronne says. His plan recommends revising what you eat, one meal at a time, to restore your sense of fullness:
Breakfast: Loading up on lean protein -- ideally from egg whites or a protein shake -- in the morning reduces hunger all day long. Eating muffins, bread, sweetened cereal and juice does the opposite. A study of 30 overweight women at Saint Louis University School of Medicine found that those who ate eggs for breakfast consumed 140 fewer calories at lunch, and ate less for the next 36 hours, compared with women who ate bagels in the morning.
Some people argue that they aren't hungry in the morning, but Dr. Aronne notes that ghrelin, the hormone that typically signals hunger, adjusts to habitual meal patterns. After a few days of eating breakfast, you should find that you are hungry in the morning, and are eating less the night before, he writes.
Lunch: Some dieters try to cut calories by skipping this meal. But going more than five hours without food causes hunger hormones to rise and fullness hormones to drop, and sends more of the calories consumed at dinner straight to fat cells. Dr. Aronne recommends starting lunch with a salad -- at least two cups of lettuce -- then more vegetables, and then lean protein. Skip the cheese, croutons, bacon and creamy dressings, he advises. Using vinegar alone will cut your appetite and slow the rise in blood sugar.
Dinner: The end of the day is fraught with temptation. Obese people consume significantly more calories at dinner than slimmer people. Here, too, load up first on salads, clear soups, or high-protein appetizers like shrimp cocktail, then have a lean protein main course. Unlike some other diet plans, Dr. Aronne's program allows a half-cup of grains or a small dessert at the end of the meal, but only if you're still hungry.
Eating bread before dinner makes people lose their sense of fullness and eat more, Dr. Aronne warns. Alcohol makes it worse by lowering your resistance and promoting fat storage.
Snacks: Like many other weight-loss experts, Dr. Aronne believes that midmorning and midafternoon snacks can act as mini appetite suppressants, preventing blood sugar from dropping too low. But the same principals apply: high-sugar, high-starch, high-fat snacks -- including those little 100-calorie cookie packs -- start a vicious cycle of more cravings, whereas fruit, nuts, vegetables and clear soups can halt them.
Beverages: It should go without saying that juice and sweet soda can add hundreds of extra calories a day. A few studies have shown that even artificially sweetened beverages can prompt people to crave real sweets during the day. Cut back on all sources of liquid calories, Dr. Aronne advises; stick with water.
To be sure, if you eat as Dr. Aronne suggests, you'll consume fewer calories overall. The point is, eating protein early in the day may make it much easier to cut down. "It definitely does make a difference," says Ned Sadaka, a New York investment manager who consulted Dr. Aronne to drop 30 pounds that had crept up on him in recent years. He's lost 21 pounds and 5 inches off his waist since January.
Not everyone agrees that consuming more protein cuts appetite. Harvard School of Public Health's Frank Sacks led a study recently published in the New England Journal of Medicine that compared 811 overweight adults on four diets with varying levels of protein, fat and carbohydrate. "We found absolutely no difference in their satiety and hunger levels," Dr. Sacks says. All the groups lost similar amounts of weight.
Other weight-loss experts say that's not surprising, since there were only modest differences in their fat, protein and carbohydrate intakes, and many participants didn't stick to their plans."
