STORY BYThe old familiar food pyramid is about to get a slight makeover. When the refined food guide pyramid and new dietary guidelines are unveiled this January by the 2005 Dietary Guidelines Advisory Committee (appointed by the Departments of Health and Human Services and Agriculture), we will start changing the way we think about eating and exercising.
"The new guidelines place more emphasis on watching caloric intake and eating more whole grains, fruits, vegetables and dairy products," says Dr. Deanna Hoelscher, associate professor of Behavioral Sciences and director of the Human Nutrition Center at the University of Texas School of Public Health at Houston.
We've all seen this equation before - the mathematics of proper nutrition and physical fitness. Add more fiber. Subtract more salt and sugar. Add more fruit and vegetables. Add in more daily exercise. With all the adding and subtracting, it's hard to tell what 'less' and 'more' actually mean.
Too many carbohydrates can increase calories, and lead to obesity. Too few carbohydrates can also be problematic. And too much fat in the diet can equal too many calories. The key is lowering your caloric intake, Hoelscher says, no matter where the calories come from.
Count calories carefully. Use fats, oil and salt sparingly.
Choose carbohydrates wisely.
"It's important to watch how many calories you take in," Hoelscher explains. "When you lower caloric intake and don't add fruits and vegetables to your diet, you leave out important nutrients."
Carbohydrates like sugar are a sticky subject. Refined sugars found in candy and sweetened drinks are not only high in calories, but also lack vitamins, minerals and fiber. The carb-counting craze has made us much more conscious about sugar intake. What's all the fuss about sugar where diets are concerned?
"Sugary soft drinks are high in calories and do not contribute any other nutrients to your diet. For example, a 12-oz cola contains 150 calories, and that's a lot, especially if you drink a few a day" Hoelscher says. "If you lower your consumption of these beverages consistently over time, you can keep excess weight off and perhaps even lose weight."
Hoelscher adds that no matter how you lower calories, be sure your diet includes foods from the major food groups so you don't miss out on important nutrients.
We roll out of bed, sit down on our way to work, ride the elevators to our offices, sit at our desks, then reverse the entire sedentary process. Somewhere in there, we eat three meals.
"We live in an environment that has engineered out physical activity," Hoelscher says. "We sit down to watch TV, use the computer and drive. Take some time to get out and walk or stand. Do chores around the house. Just move. And be sure to watch those calories."
Hoelscher says it's all about changing our inactive lifestyle to an active one. She suggests you exercise 60 to 90 minutes a day to avoid weight gain or even lose weight.
Remember the four food groups your mother used to talk about? The Food Guide Pyramid has taken its place over the years. Here's what the current pyramid looks like:
Experts Issue Report on 2005 Dietary Guidelines:
The 13-member 2005 Dietary Guidelines Advisory Committee has released its recommendations, which will serve as the basis for the Sixth Edition of Nutrition and Your Health: Dietary Guidelines for Americans due out in January 2005. First published in 1980, the Dietary Guidelines are reviewed, updated and released every five years. You can read the report at www.health.gov/dietaryguidelines.

Sometimes, a deck of cards helps us understand serving sizes better than ounces and grams. Jeanne Martin, Ph.D., director of the Dietetic Internship Program at the UT School of Public Health at Houston suggests using these single portion visual aids to guide you through the "how much is too much" riddle:

Special Instructions for Children Being Vaccinated Against Flu for the First Time:
Children 6 months up to 9 years of age getting a flu vaccine for the first time will need two doses of vaccine the first year they are vaccinated. If possible, the first dose should be given in September or as soon as vaccine becomes available. The second dose should be given 28 or more days after the first dose. The first dose "primes" the immune system; the second dose provides immune protection. Children who only get one dose but who need two doses can have reduced or no protection from a single dose of flu vaccine. Two doses are necessary to protect these children. If your child needs two doses, begin the process early, so that children are protected before influenza starts circulating in your community. Be sure to follow up to get your child a second dose if they need one. It usually takes about two weeks after the second dose for protection to begin.
Because flu viruses change every year, the vaccine is updated annually. So even if you or your children got a flu vaccine last year, you both still need to get a flu vaccine this season to remain protected. If October and November slip by, and you haven’t gotten your children or yourself vaccinated, get vaccinated in December or later.
