How To Get Kids To Eat Healthy

The 14,300 students served by the public school cafeterias in Lee's Summit, Mo., have delicious yet healthy options.

Among the menu items are fresh watermelon, fresh carrots with low-fat ranch dip, baked chicken nuggets, chilled (frozen) strawberries, low-fat mashed potatoes with non-fat gravy, and pizza with whole grain crust and low-fat cheese. They even enjoy roasted, shredded pork sandwiches with homemade whole grain rolls dressed in a low-sodium barbecue sauce--perhaps no surprise for a district that resides in the Kansas City metropolitan area.

"We're educating them through the meals we provide," says Jane Hentzler, a registered dietitian and director of nutrition services for the school district. The healthy fare, she says, is designed to teach the schoolchildren about the proper ratio of nutrients and how to create balanced meals with the best ingredients available.

Hentzler's approach, which also includes classroom lessons on nutrition, is part of a nationwide trend that aims to increase access to minimally processed fresh food at school. The alarming rate of childhood obesity has prompted the reformative strategy at school districts across the country; 12.4% of children ages 2 to 5 are overweight or obese, as are 17% of children and teens between 6 and 19. According to the Centers for Disease Control and Prevention, kids who are obese in their preschool years are more likely to be obese adults and have higher chances of developing hypertension, asthma and diabetes.

Yet, healthier school fare is only one part of a successful equation. Arguably more important is the role parents play in teaching their children about nutrition and making healthier choices.

Educated Eating

In that respect, parents have more help from school cafeterias than ever before.

A recent report produced by the School Nutrition Association, a lobbying and membership organization of 55,000 food-service directors, caterers and manufacturers, found that more schools offer healthy options.

In a survey of 1,200 food-service directors, nearly 60% reported that they currently provide or are considering offering local fruits and vegetables. Since 2007, vegetarian options have increased by 12%, and low-fat prepared and packaged foods have increased by 11.5%. More than 90% of those surveyed said their schools provided whole grain items and salad bars or pre-packaged salads.

Top Tips

  • Respect Likes and Dislikes
  • Appeal to Their Interests
  • Talk About Nutrition
  • Be Mindful of Hidden Calories

The shift partly has to do with changing student demand and local and state wellness initiatives. This fall, Congress will also determine whether or not to increase funding and institute national guidelines for the Child Nutrition Act, which is renewed every five years and spends $12 billion annually to feed breakfast and lunch to 31 million schoolchildren.

Cathy Schuchart, staff vice president for the SNA's Child Nutrition and Policy Center, says that more uniform guidelines will help food manufacturers, who often try to accommodate different local and state regulations by making several versions of the same product, become more efficient. Extra cost-savings, says Schuchart, will allow providers to focus on incorporating higher quality but more expensive items like fresh fruits and vegetables and whole grains.

Though major strides have been made in providing more nutritious food to schoolchildren, more work remains. The NPD Group, a market research company, has found differences between what children ages 6 through 12 eat when their lunch is packed at home versus when it is bought at the cafeteria.

Though kids who dine on cafeteria food are most likely to enjoy milk, a sandwich and fruit (in that order), they also frequently eat pizza and French fries. Children who bring their lunch from home are most likely to pack a sandwich, fruit and a salty snack. Cookies are popular in both groups, but kids with home-packed lunches are also likely to bring yogurt and crackers.

Model Behavior

The differences between the groups demonstrate what is obvious: Mom and dad have some sway when it comes to healthy eating. In fact, NPD's research has also shown that children are most likely to receive guidance on healthy eating from a female parent, followed by the school and then from a male parent.

"Modeling is so important," says Kerry Neville, a registered dietitian in Kirkland, Wash., and spokeswoman for the American Dietetic Association. "I see so many examples of parents saying one thing and doing another." A diet-soda drinking parent who asks a child to fill his or her glass with milk, for example, will meet resistance.

Neville also recommends that parents stock the house with healthy choices and make them visible, which may seem intuitive but is an often overlooked step. While making dinner for her 9-year-old son, Neville places carrots and dip and a fruit basket on the counter to steer him toward nutritious snacks.

Setting guidelines and monitoring a child's diet can provide structure, but Neville says the line between being watchful and policing is thin. She allows her son to have just one treat a day, whether that's a soda or cupcake and gently reinforces the rule when she can. Neville also reviews the school lunch menu with him and asks about his favorite items so that she's aware of his choices and can help better inform them when necessary.

Instead of aiming for perfection, Neville tries for consistency so that her son is regularly exposed to healthy options.

"It really is tough," she says. "The best you can do is to make sure they eat healthy when they are under your control."

Swine flu: How serious is the global threat?

Q: What's the real story about swine flu? I've heard it's the next global pandemic, but I'm not sure what that means.

No name / No state given

You're not alone in your confusion about the current swine flu outbreak, which seems to have started in Mexico. Since then, the swine flu strain of influenza has also spread to the United States, Canada and many other countries. In June 2009, based on its wide spread to many nations, the World Health Organization declared the swine flu outbreak a global pandemic.

Swine flu is one of the many type A influenza viruses. It's unusual for humans to catch swine flu, but occasional cases occur, usually in people who have contact with infected pigs. Like other flu viruses, the swine flu virus changes its DNA as it spreads, giving rise to a number of subtypes.

Health officials around the world are concerned about the swine flu outbreak because:

  • It's caused by a new strain of swine flu virus, which means humans haven't had a chance to develop antibodies that could be used to make a vaccine. The new strain is a variant of a recognized swine flu virus — swine influenza virus H1N1. The new form contains DNA sequences from human and avian influenza viruses, as well as from other strains of swine influenza.
  • The infection progresses rapidly. In those most severely affected in the Mexican outbreak, potentially fatal respiratory problems developed after less than a week of coughing, aches and fever.
  • In Mexico, the death rate was unusually high among those who developed respiratory distress.

In the United States, the swine flu infected some people who had recently visited Mexico and their household contacts. But, the infection resulted in relatively mild respiratory illnesses in this group.

Why such a big difference in severity? One possibility is that the virus mutated to a less dangerous form around the time it showed up in the United States. Another, more sobering possibility is that the severe illness linked to swine flu in Mexico was the result of viral mutations that haven't yet appeared in other countries — but possibly will in time.

Efforts to understand and contain swine flu are under way on a global scale. Until more definitive information is available, the best response for those outside the most affected areas is to:

  • Keep tabs on respiratory symptoms. If you or someone in your family develops symptoms suggesting a cold or the flu, be alert for persistent or worsening symptoms, particularly a high fever.
  • Stay home if you're sick. If you do have swine flu, you can give it to others starting about 24 hours before you develop symptoms and ending about seven days later.
  • Wash your hands thoroughly and frequently. Flu viruses can survive for two hours or longer on surfaces, such as doorknobs and countertops.
  • Take extra precautionary measures if you travel to or live in an affected area.
  • If you have a chronic condition, such as asthma or heart disease, it's a good idea to wear a breathing mask when you're out in public in affected areas.
  • Be prepared. Ask your health care provider or county health department about infection-control plans in case of a serious swine flu outbreak. The antiviral drugs oseltamivir (Tamiflu) and zanamivir (Relenza) reduce the severity of symptoms.

Swine Flu: The Basics

Definition

Swine flu refers to a respiratory infection caused by influenza A viruses that ordinarily cause illness in pigs. Humans can catch swine flu from infected pigs, but pig-to-human transmission is unusual. Human-to-human transmission of true swine flu is also possible but infrequent.

The recent outbreak of what is being called swine flu involves a new H1N1 type A influenza strain that's a genetic combination of swine, avian and human influenza viruses. It's capable of spreading from human to human.

In June 2009, based on its wide spread to many nations, the World Health Organization declared the swine flu outbreak a global pandemic.

This new swine flu strain is being called by a number of names, including: swine-origin influenza A, swine influenza A (H1N1), influenza A/California/H1N1, swine origin influenza virus, North American flu and influenza A (H1N1).

The best approach you can take is to try to avoid infection. If you do develop symptoms of swine flu, seek prompt medical attention so that you have the best chance of antiviral drugs providing you with successful treatment.

Symptoms

The symptoms of swine flu in humans are similar to those of infection with other flu strains.

  • Fever
  • Cough
  • Sore throat
  • Body aches
  • Headache
  • Chills
  • Fatigue
  • Diarrhea
  • Vomiting

Symptoms develop three to five days after you're exposed to the virus and continue for about another week. You can pass the virus to other people for about eight days, starting one day before you get sick and continuing until you've recovered.

When to see a doctor
See your doctor immediately if you develop flu symptoms, such as fever, cough and body aches, and you have recently traveled to an area where H1N1 swine flu has been reported. Be sure to let your doctor know when and where you traveled.

Also see your doctor if you develop respiratory symptoms after you've been in close contact with someone who may have been exposed to H1N1 swine flu.

Doctors have rapid tests to identify the flu virus, but there is no rapid test to differentiate swine influenza A H1N1 from other influenza A subtypes.

Causes

Influenza viruses infect the cells lining your nose, throat and lungs. You can be exposed to swine flu virus if you have contact with infected pigs. The virus enters your body when you inhale contaminated droplets or transfer live virus from a contaminated surface to your eyes, nose or mouth on your hand.

Risk factors

Swine farmers and veterinarians have the highest swine flu risk because of their exposure to pigs.

If you've traveled to an affected area, you may have been exposed to human swine influenza A H1N1, particularly if you spent time in large crowds.

Complications

Influenza complications include:

  • Worsening of chronic conditions, such as heart disease, diabetes and asthma
  • Pneumonia
  • Respiratory failure

Severe complications of human swine flu H1N1 seem to develop and progress rapidly.

Treatments and drugs

Most cases of flu, including human swine flu, need no treatment other than symptom relief. If you have a chronic respiratory disease, your doctor may prescribe additional medication to decrease inflammation, open your airways and help clear lung secretions.

Antiviral drugs can reduce the severity of symptoms. There are two classes of antiviral medication used to reduce symptoms and duration of the flu — adamantane antivirals and neuraminidase inhibitors — but flu viruses can develop resistance to them.

Human swine flu H1N1 is sensitive to oseltamivir (Tamiflu) and zanamivir (Relenza), both of which are neuraminidase inhibitors. It's important to start treatment as soon as possible after you become ill. These antiviral medications are most effective if treatment begins within 48 hours of developing symptoms.

Lifestyle and home remedies

If you come down with any type of flu, these measures may help ease your symptoms:

  • Drink plenty of liquids. Choose water, juice and warm soups to prevent dehydration. Drink enough so that your urine is clear or pale yellow.
  • Rest. Get more sleep to help your immune system fight infection.
  • Consider pain relievers. Use an over-the-counter pain reliever such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others) cautiously, as needed. Remember, pain relievers may make you more comfortable, but they won't make your symptoms go away any faster and may have side effects. Ibuprofen may cause stomach pain, bleeding and ulcers. If taken for a long period or in higher than recommended doses, acetaminophen can be toxic to your liver. Talk to your doctor before giving acetaminophen to children. And don't give aspirin to children or teens because of the risk of Reye's syndrome, a rare but potentially fatal disease.

Prevention

These measures may help prevent flu:

  • Stay home if you're sick. If you do have swine flu, you can give it to others starting about 24 hours before you develop symptoms and ending about seven days later.
  • Wash your hands thoroughly and frequently. Use soap and water, or if they're unavailable, use an alcohol-based hand sanitizer. Flu viruses can survive for two hours or longer on surfaces, such as doorknobs and countertops.
  • Avoid contact. Stay away from crowds if possible.
  • Reduce exposure within your household. If a member of your household has swine flu, designate one other household member to be responsible for the ill person's close personal care.
