What is your daily recommendation for vitamin C?, assignment help


Question Description

Assignment # 1

To select excellent food sources of vitamin C that would meet your personal daily DRI for vitamin C.  Based on your dietary analysis, it is highly likely you did not meet your DRI for vitamin C if you do not include 5 or more servings of fruits and vegetables in your daily diet.  Vitamin C is one of the most popular single supplements sold and most people take vitamin C for preventing a cold or reducing risk of infection.  Supporting a healthy immune system is one of many important functions of vitamin C but it does NOT prevent the common cold.  This activity will let you practice selecting vitamin C rich foods to meet your daily needs.  Since vitamin C is a water soluble vitamin, we need it every day.


  1. What is your daily recommendation for vitamin C?
  2. Write down 5 different foods that would each individually meet your DRI for vitamin C. Include portion sizes and total amount of vitamin C in each food item.

Assignment # 2

To compare the amount of vitamins and minerals in a supplement to your own personal DRI/RDA recommendations. Based on a 2011 study at Univ of California, Berkeley, more than 50% of us take at least one vitamin or mineral supplement each day.  Of those taking a supplement, 82% take a multivitamin/mineral supplement to the tune of over $25 billion dollars a year.  Another study reveals there is no association between multivitamin use and the reduced risk of mortality, any type of cancer or almost any type of cardiovascular disease.  In other words, many of the supplements we take are not supporting heath yet we still take them.  This activity will help you evaluate a good vs.. potentially dangerous supplement.  We recommend no more that 100% of your DRI should be taken in any supplement unless for clinical therapy.  Here you will compare a supplement with your own personal DRIs to assess its benefit. 


  1. Select a supplement you are currently taking or look at a label in the grocery store. Your supplement MUST contain 8 or more vitamins and/or minerals.
  2. Complete the Vitamin/Mineral Comparison worksheet above. Record the nutrient profile of the supplement and then compare the nutrient levels with your personal DRIs. The charts in the front cover of your text will provide all your DRIs.
  3. Also, for many supplements you will need to convert IU to mg or ug (mcg) in order to compare them. To help you with the calculations use these conversions:

    Vitamin A: 1 IU = 0.3 mcg (10,000 IU X 0.3 = 3000 mcg or 3000 RAE
    Vitamin D: 1 IU = 0.025 mcg (400 IU X 0.025 = 10 mcg)
    Vitamin E: 1 IU = 0.67 mg eg. 30 IU x 0.67 = 20 mg (natural vitamin E)
     1 IU = 0.45 mg 30 IU x 0.45 = 13.5 mg (synthetic vitamin E)
  4. Submit your worksheet above.
