1. Explain three ways in which vitamins differ from macronutrients and include examples from each group. (15 pts)
2. Examine your average intake of water-soluble vitamins. Which of these did you consume at least 75% of your personal DRI? (See Intake vs Goals Report) (5 pts)
3. For any water-soluble vitamin in which your intake was 75% or more of your personal DRI, answer the following questions.
a. List the Tolerable Upper Limit (UL) for each vitamin that was 75% or more of your personal DRI. Did your intake exceed the UL for any of these vitamins? (See Table of Tolerable Upper Limits (UL) for Vitamins in the Dietary Reference Intakes (DRI) appendix of the textbook) (15 pts)
b. Describe the functions served in the body and at least one potential consequence of exceeding the UL for each vitamin listed in part a. (15 pts)
c. List one food you consumed that contributed to your intake of each vitamin listed in part a. (10 pts)
4. Which water-soluble vitamins were less than 75% of your personal DRI? (See Intakes vs Goals Report) (5 pts)
5. Explain at least one potential consequence of long-term deficiency in vitamins in which your intake didn’t meet 75% of your personal DRI. If you met at least 75% of the RDA for all water-soluble vitamins, choose one vitamin and explain two potential consequences for deficiency. Include in your explanation how the vitamin function that is compromised causes these symptoms of deficiency disease. (20 pts)
6. For each water-soluble vitamin in which you didn’t meet 75% of your personal DRI, provide an example of a food source to improve your intake. (15 pts)
Here are three key ways vitamins differ from macronutrients:
Quantity: Macronutrients are needed in large amounts (grams) to provide energy and build body structures. Examples include carbohydrates, proteins, and fats. In contrast, vitamins are needed in much smaller quantities (milligrams or micrograms) to regulate various bodily functions. For instance, Vitamin C is a water-soluble vitamin required in milligrams, while carbohydrates, a macronutrient, are consumed in grams.
Energy Source: Macronutrients are broken down by the body to generate energy. Fats, carbohydrates, and proteins all contribute to the body’s energy production. Vitamins, on the other hand, don’t directly provide energy. Instead, they act as coenzymes, facilitating metabolic processes that utilize energy from macronutrients. For example, Vitamin B complex vitamins help convert carbohydrates into usable energy.
Storage: The body can store excess macronutrients, like fat, for later use. Conversely, water-soluble vitamins are generally not stored in the body and need to be consumed regularly through diet. Fat-soluble vitamins (vitamins A, D, E, and K) can be stored in the liver and fatty tissues for some time.
Unfortunately, I cannot access your personal Dietary Intake vs Goals Report. To answer question 2, refer to your report and identify any water-soluble vitamin where your intake reached at least 75% of your DRI.
Since I cannot access your report, I cannot answer questions 3a, 3b, and 3c specifically. However, I can provide a general framework to analyze these aspects for any water-soluble vitamin where your intake met 75% of the DRI.
3a. Tolerable Upper Limit (UL) and Intake Comparison:
3b. Vitamin Functions and Consequences of Exceeding UL:
3c. Food Sources of High Intake Vitamins:
4. Refer to your Dietary Intake vs Goals Report and identify any water-soluble vitamins where your intake fell below 75% of your DRI.
Here’s how to approach this question:
For your chosen vitamin (or each deficient vitamin):
For example, Vitamin C is crucial for collagen production and immune function. Deficiency can lead to impaired wound healing, increased susceptibility to infections, and bleeding gums.
