Introduction

Vitamins are divided into two groups: fat-soluble and water-soluble. The fat-soluble vitamins need the presence of dietary fat and the assistance of bile to be effectively absorbed. They aren’t excreted as easily as water-soluble vitamins, making them more likely to cause toxicity. However, this rarely occurs when consuming vitamins exclusively through foods. The water-soluble vitamins are generally not stored in the body so deficiency conditions of the water-soluble vitamins develop more quickly than for the fat-soluble vitamins.

In this activity, you will identify the sources of fat-soluble and water-soluble vitamins in your diet and compare the amount you get with the current dietary recommendations.

This activity can be completed using the Analyze My Diet tool linked from your LaunchPad course or any dietary analysis software that provides the daily average amount of vitamins consumed.

To complete the activity using Analyze My Diet:

  • If you have not already completed the Analyze My Diet Tutorial and tracked at least one day’s nutrition and activity, do so first.
  • Within Analyze My Diet, go to the Reports tab.
  • Select “Bar Graph” on the left.
  • Select the day(s) that are a good representative of your typical diet.
  • Click “Show Report” to download your Nutrition Report.
  • Within the report, you will see the value (average consumption per day), goal (daily target), and Percent (completion of target consumption) for each nutrient.

For more instructions and help using the Analyze My Diet Tool, please visit the help page.

Use the Nutrients Report to find your data and enter it into the grid below using only numerical values and decimal points. To calculate the percent of the target that you ate, divide your Average Eaten value by the Target value and multiply by 100.
Vitamins Goal (Daily target consumption) Value (Average consumption per day) Percent (Completion of target consumption)
Vitamin A (μg/mcg)
Vitamin B6 (mg)
Vitamin B12 (μg/mcg)
Vitamin C (mg)
Vitamin D (μg)
Vitamin E (mg)
Vitamin K (μg)
Folate (μg)
Thiamin (mg)
Riboflavin (mg)
Niacin (mg)
Choline (mg)
