PERSONAL FOODCHART

Assignment Due Date: October 18

Each student will keep track of food intake for5 consecutive days. Using the tables at the back of the study guide, compute the daily consumption of calories, fat, protein, carbohydrate, calcium, iron, vitamin A, vitamin C, and folic acid. Compute the consumption in each of the categories for each day of the 5 day period. Compute an average daily consumption for each nutrient.

Answer the following questions:

1. Does your dietary intake meet the RDA for your age group and sex? If not, in what areas are you lacking? What foods could you add to your diet to increase your consumption and bring you up to the RDA?

2 .What foods in your diet are the major contributors of calories? Protein? Carbohydrate? Calcium? Iron? Vitamin A? Folic acid? Vitamin C?

3. What percentage of your calories werederived from fat? From protein? From carbohydrate?

A.g of fat X 9 cal/g =calories from fat

B.g of carbs X 4 cal/g =cals from carbs

C.g of protein X 4 cal/g = cals from protein

Total calories = sum of cals from pro, fat and carb

% of cals from fat = [calories from fat / total calories]100

4. If you wanted to lose one pound per week (approximately 3,500 calories ), what changes would you make in your diet? HINT! You should provide a list of foods and amounts that add up to 3500 calories.

5. If you were to complete a food chart and find that you failed to meet the RDA in several categories, would this mean that you were headed for nutritional disorders? Explain briefly.

6.. Using the data supplied, approximate your caloric needs for a typical day (Show calculations in your report).

7. If you wanted to lose one pound (approximately 3,500 calories ) per week, how could you accomplish this by exercising and not by altering your eating habits?. HINT!( Show calculations)

8. There is much interest in low fat diets today. Put together three meals having a total calorie content of at least 1800 calories that has no more than 10% of the calories from fat. You do not need to have all of the foods have less than10% of their calories from fat, but the average should be 10% or less. Try to make this something you might actually consider eating.

HINT: Start with your day that has the lowest %of calories from fat and make substitutions oradditions/deletions as needed. You may want to utilize a list of foods sorted by % calories from fat that is on the webpage.

Supermarket Survey – Due November 15


In lieu of class on October 25; you will make a trip to the supermarket and answer the following questions. You may work I ngroups on this if you choose to do so. If you work in a grou plist who worked with you. Go to your favorite or perhaps the most convenient supermarket and survey the following:


Dating

1. What types of products have dates on them? What do these dates mean?
2. As a consumer who realizes that there is a cost associated with everything we require on a label, what products should be required to have a date on them? Why?
3. Would you buy a food that was "out of date" at a reduced cost? Why or why not?


Food Safety Information

1. What messages about food safety did you find?
2. There are a number of "warnings" that appear on food labels. List at least three different ones of these. More credit for bigger lists.
3. Rate each of these warnings. Which would you pay more attention to? Which do you think are most effective in communicating with average consumers? Least? Why?

Price/value

1. What are the five most expensive food items you could find?
2. Assume that you are in charge of food purchases and health for your living group (i.e. dorm, apartment, home, etc.), list 5 foods that you feel are the best values. Explain your choices in detail.

Products

1.Look at the ingredient statements on ten products. What types of products have the longest list of ingredients? The shortest?
2.For the product with an ingredient list that is most interesting to you, bring in a label or a copy of the information on the label (name, manufacturer, ingredients and preparation
instructions) for class discussion. We will discuss what is there and why it is used.
3.Choose a product that you’d like to know how it is made. Bring the product or label information to class.

Article Critiques

One important goal of this course is to make you better consumers of food and nutrition information. To help you develop, we will be giving you newspaper articles, news releases or perhaps even videotapes and asking you to respond to these. Questions we will expect you to respond to include: What claims are stated here? What additional claims are implied? Wha tare the weak points of the argument? the strong points? Wha tadditional questions should be asked? Where could you go to find out more information about this topic? These responses should be one page or less. Evaluation will be based on the thoroughness and insightfulness of your response.

You will have 2 of these to do. They are due September 27 and October25.
