Directions
Click on the calculator and use it to compute values for the highlighted cells of the tables and type these values into the cells. Use the Enter or Return key to input the data. The data in the succeeding cells of each table will automatically be calculated for you.
Complete Table 3
- Calculate the average number of markers remaining in the stomach 180 minutes after ingestion of radiopaque markers with the standard meal, insoluble fiber-rich meal, and soluble fiber-rich meal. The average numbers of markers remaining in the stomach 60 and 240 minutes after ingestion will be calculated automatically.
- Calculate the average percentage of markers remaining in the stomach 180 minutes after ingestion of radiopaque markers with the standard meal, insoluble fiber-rich meal, and soluble fiber-rich meal. Remember that the total number of ingested markers is equal to 24. Average percentage of markers remaining in stomach 60 and 240 minutes after ingestion will be calculated automatically.
Complete Table 4
- Calculate the total number of the markers remaining in the colon 24 hours after ingestion of radiopaque markers with the standard meal, insoluble fiber-rich meal, and soluble fiber-rich meal. The total number of markers remaining in the colon 48 and 96 hours after food ingestion will be calculated automatically.
- Calculate the average percentage of markers remaining in the colon 24 hours after ingestion of radiopaque markers with the standard meal, insoluble fiber-rich meal, and soluble fiber-rich meal. Remember that each subject ingested 24 markers. The average percentage of markers remaining in the colon and in sections of the colon 24, 48 and 96 hours after ingestion will be calculated automatically.
Complete Table 5
- Since optical density (OD) reflects the amount of bile acid in the filtrate (not adsorbed by meal particles) then 1-OD reflects the amount of bile acid adsorbed by meal particles. Calculate 1-OD for the standard meal with bile acid and the fiber-rich meal with bile acid in the first trial of the experiment. 1-OD will be calculated automatically for the other trials.
- Calculate the average OD and the average 1-OD for the standard meal with bile acid and the fiber-rich meal with bile acid in the first trial of the experiment.

Equations (fx)
Use these formulas for making your calculations. Round your answer to the nearest tenth.
Averages
Add the values from the three trials (or subjects); divide by three.
Percentage of the number of markers in GI tract
Divide the number (n) of the markers observed by 24 and multiply by 100: (n/24)* 100%.
Your data will not be saved until the table is completely filled in.

Index reflecting the level of bile acid adsorption
This index is equal to 1 - OD, where OD is optical density of the colorized supernatant of mixtures of the studied food. This index reflects the amount of bile acid adsorbed by food particles.
