TESC –What’s Cookin’’ Fall 2005

Mineral Lab

DUE: OCTOBER 20 NO LATE PAPERS – NO EXCEPTIONS!

Part One:

Keep a diet diary for 3 day using Nutrition Calc Plus or any other food composition source. 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:

.

ü Note the totals of the daily intake of each nutrient [Calcium, Iron, Magnesium, Potassium, Phosphorus, Sodium & Zinc].

ü Find the difference between your intake and the amounts from your profile page. Please include a copy of this page with your assignment.

ü Print out the appropriate charts to submit – make sure they show the nutrient amounts [the bar graph or spreadsheet might be most appropriate]

Part Three:

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

• Review your diet diaries. Comment on the amount suggested by your profile page, and the Dietary Reference Intake [DRI] level, are they equivalent? Charts can be found in the front and back covers of text, and the chart on the last page of the textbook. Determine your individual needs for each nutrient, and indicate if your daily individual intake met or was out of range for these.
• 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 or your profile? (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 question, 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.
