You will either be strapped to an x-ray table that tilts vertically, or you will be seated in a chair. You will consume a barium-containing meal. The consistency of the items in the meal varies, ranging from thin liquid to semisolid foods for example, applesauce or solid foods such as a cookie. As you swallow different amounts of the meal items, the examiners use fluoroscopic imaging to observe the swallowing process on a television screen in order to determine which foods are difficult for you to swallow and which structures are responsible for the problem.

The swallowing process may be observed at normal speed or in slow motion. Other than chewing and swallowing, you must remain still during the procedure.

A speech pathologist is also normally present during the test to evaluate your swallowing ability and, if possible, to suggest some possible corrective actions. The test usually takes from 30 minutes to 1 hour depending on the findings. Although radiation exposure during this test is minimal, you will receive a higher dose than during standard x-ray procedures. You may leave the testing facility immediately and resume your normal diet and activities.

Drink plenty of fluids to help eliminate the barium from your system. Your stool will be chalky and light-colored initially, but it should return to normal color after 1 to 3 days. The doctor will try to identify the nature and origin of your swallowing problem on the viewing monitor during the test.

If possible, the speech pathologist will recommend specific corrective actions to help you resolve the swallowing problem during the test and no further testing or treatment is needed.

If the test findings are still not definitive after the recorded x-rays and video have been reviewed, or if the test reveals abnormalities that require further evaluation, additional tests such as esophagogastroduodenoscopy may be ordered.

Additional activities that focus on how, as people grow up, the amounts and kinds of food and exercise needed by the body may change, will be necessary for students to gain a full understanding of this benchmark.

You also could print this out ahead of time and distribute to students. You should structure this activity in a way that matches the reading levels of your students. Students could read the article on their own, or you could read it aloud to a class. Students should answer the quesetions on the Good Food, Good Health students sheet.

Keeping in mind these figures, ask students the questions from your teacher sheet. After discussing the guide, talk about how kids as a whole could go about eating the recommended number of servings from the five major food groups.

Ask students why it is important to eat the right foods. Have a discussion with them about their various views. If time allows, you may wish to extend this activity by having students survey their classmates about typical snack choices. This survey can be done in the class, grade, or school-wide. Have students to go to the Nutrition Café's Nutrition Sleuth game.

This game can provide students with a good introduction to how vitamins and minerals are essential to keep everything working well. Since there are seven different cases students can attempt to solve, you can break up students into teams and have each team tackle a case. Students should write down what they learn about the nutrients on the Good Food, Good Health student sheet.

Once the teams have solved the cases, have them report to the class what they learned. You might want to create a table for the whole class, using a large sheet of paper. After the class has finished this exercise, ask students the questions from the teacher sheet. Once you have discussed the chart with them, ask students to think about the number of servings of each of the food groups they had the day before. You might want to create a chart and write down the number of servings per student for each of the food groups.

Then, have students determine the average number of servings the class ate. Compare those numbers to the national averages for each of the food groups. Be sure to exclude French fries and potato chips from the vegetable group. Discuss with students how they might increase the number of servings of food from the five food groups they eat in a day and the importance of eating a balanced diet in order to get the vitamins and nutrients they need to keep their bodies working well.

To have students create the MyPlate, divide them into five different teams, each one concentrating on a particular food group. But, instead of just listing the five food groups and the number of servings that should be eaten from each, students also should include the types of food found in the food groups and the types of nutrients that can be obtained by eating those foods.

They should state why the nutrients are important for helping to keep their bodies working well. Students also could illustrate the plate with pictures of the body parts for which these foods are particularly good.
