TESC – Understanding Your FoodFall 2003

Mineral LabDUE: OCTOBER 29NO LATE PAPERS – NO EXCEPTIONS!

Part One:

Keep a diet diary for 3 days.Be sure to include at least one weekend day, the days do not have to be sequential, but it helps when looking for trends.For each entry, approximate portion size, ingredients, etc.Include all beverages, snacks and meals.Do not include any supplements when tracking daily food/beverage intake, which will be considered separately.

Part Two:

üUsing Appendix N or any other food composition source, give values to all nutrients indicated.

üTotal the daily intake of each nutrient.Remember to change units if necessary to keep uniform.

üUsing the Dietary Reference Intake charts in the front and back covers of text, and the chart on the last page of the textbook, find your individual needs for each nutrient, and list it in the appropriate line on EACH grid.

üFind the difference between your intake and your DRI, and fill in the grid sheets with correct numbers.Remember to keep units uniform.

Part Three:

On a separate sheet of paper, type your answers to the following:

• Review your diet diaries. Comment on the amount suggested (DRI) vs. your daily individual intake, did you obtain adequate amounts each day? Note if you take supplements what impact they have on your daily nutrient levels i.e. do they bring you into the correct range, do you not need to take them, etc. What about ratios? Comment on your Ca:Mg and Na:K ratios. [Hint: If you need to – look up recommended ratios in text]
• Average your intake of each nutrient over the three days, and comment on how this amount compares to the DRIs? (Remember the DRIs were originally set based on three-day averages) Again, if you take supplements comment on the impact they have on your average nutrient levels i.e. do they bring you into the correct range, do you not need to take them, etc.
• What foods and /or preparation practices could be changed [in what way] to modify your nutrient intakes?

For the following questions, you may have to do some additional reading – if you use any source outside of the textbook/class notes, please be sure to indicate the source.

• Ilene is a vegan. She stopped eating meat and dairy products when she was 17 yrs old, and is now in her mid 20s. She wants to start a family but is concerned about whether she can obtain enough calcium and other nutrients from her diet to ensure her baby’s growth and health. She is also concerned about osteoporosis. How can she consume enough calcium to meet her own and her baby’s needs? Which other nutrients should she be concerned about? Please list them with a brief comment about why you included them.

• After winning a soccer match, the TESC soccer team goes to a local tavern to celebrate. After a few beers, one of the midfielders [they run a lot during a game!] begins to feel shaky and disoriented; his feet and hands have a “pins and needles” sensation. What physiologically could be taking place to cause these occurrences?
