Diets of the Past & Present 2011 NEH Summer Institute: Bridging Cultures- Diversity & Unity in the Pueblo World Lori Coles Meade High School Meade, KS Summary This lesson is designed for a 10th grade biology course. The lesson looks at basic nutrition & introduces the new USDA My Plate concept of healthy eating. It could be used after discussing the macromolecules (carbohydrates, lipids & proteins) or while discussing digestion. During the lesson students will compare their modern day diet with that of the ancient Pueblo Indians of Mesa Verde. Learning Outcomes Students will be able to categorize foods into the correct food groups according to the USDA food groups Students will be able to identify which foods contribute carbohydrates, lipids & proteins to their daily food intake Students will be able to recognize the differences & similarities (diversity & unity) of their modern day diet with that of the ancient Pueblo Indians Materials Photocopy of Diets of the Past & Present Part 1- one per student Photocopy of Food Groups pages- one per student Photocopy of Diets of the Past & Present Part 2- one per student Photocopy of Pueblo Indians of the Past expository- one per student Items to show portion sizes: measuring cups (1/2 & 1 cup sizes), deck of cards, etc Total Duration 2 class periods (50 min each) Procedures Teacher Preparation Make copies of handouts: Diets of the Past & Present Parts 1 & 2, Food Groups and Pueblo Indians of the Past Locate & display items to show portion sizes Review & bookmark web resources that will be used with the class during discussions Lesson Introduction Duration: 10 min Begin by asking students why they eat food. Lead them to a realization that food is for the nourishment of our bodies & that without it our cells/bodies would die. Have them reflect on how healthy they think they eat on a daily basis. Activity Part 1 Duration: 35 min After a review of why we eat food, students will record what they remember eating from yesterday. Approximate amounts will be included. Display measuring cups & such so that students can better estimate their amounts that they ate. It may be helpful to model for the students by listing your foods 1 on the board for them to see. After listing food, have them categorize them as carbohydrate, lipid, or protein & add those indications to the chart. Finish Part 1 by looking at the recommended daily servings & comparing it to what they really ate. Remind students that the recommendations are based on a 2000 calorie/day diet. Discuss as a class the food groups & how some foods will include more than one type of macronutrient. It might be a good time to review the roles of macronutrients (carbohydrates, lipids & proteins) in the human body. Discussion may also want to look at micronutrients that the students are familiar with (vitamins B, C, D & minerals such as calcium & iron). Have the students finish the questions at the end of the period or as homework. Web Resources Title: United States Department of Agriculture ChooseMyPlate.gov URL: http://www.choosemyplate.gov Description: This website includes information on healthy eating & the new my plate campaign that is replacing the food pyramid used for many years. It can be used to help guide students to categorize food as well as see what a healthy diet includes. Supplemental Documents Title: Diets of the Past & Present Part 1 Description: This document leads the students through a simplified analysis of their daily food intake from yesterday. Title: Food Groups Description: This modified resource from the USDA website helps students in categorizing food which may be helpful in deciding which foods have carbohydrates, lipids & proteins. It also contains a graphic of the USDA My Plate that is now being used to help Americans balance their diets. Title: Diets of the Past & Present Part 1 Answer Key Description: This document gives sample answers for Part 1 of the activity. Activity Part 2 Duration: 30 min With the students, review what they did in Activity Part 1 & what they learned. Lead them to a discussion of where most of their carbohydrates, lipids & proteins come from in daily food selection. Also review with them the roles of macro/micronutrients in their bodies. Introduce the Mesa Verde region & the ancient Pueblo Indians that lived there. Discuss their lifestyle & diet using the handout “Pueblo Indians of the Past.” Have students do a similar listing & categorizing of foods with the Pueblo Indian diet as they did with their own diets previously. Note: Corn made up about 60-80% of a Pueblo Indians’ daily diet. There is no real way of knowing how many calories they ate on a daily basis but based on 4 cups of corn/day, a Pueblo Indian ate approximately 700 calories/day. For ease in comparison, round that up to 1000 calories/day so their daily intake of food would be half of the recommended daily intake for modern day diets. Although Pueblo Indians tended to eat a flour corn instead of sweet corn, the nutritional information for sweet corn is: 1 cup of sweet corn contains 5 grams of protein, 29 grams of carbohydrates, 1 gram of fat, & 132 calories.

Title: Pueblo Indians of the Past Description: This document includes an expository text describing the ancient Pueblo Indian diet. Title: Diets of the Past & Present Part 2 Answer Key Description: This document gives sample answers for Part 2 of the activity. Conclusion Duration: 20 min Lead the students through the comparison of their modern day diet with that of an ancient Pueblo Indian. Discuss the idea of “diversity” by looking at differences between their food choices & those of the Pueblo Indians. Then look at the idea of “unity” by looking at similarities between their food choices & those of the Pueblo Indians. Wrap up with a discussion of how all cultures have similarities in the foods that they eat & that all humans are alike biologically. Survey students for additional examples to emphasize the concepts of diversity & unity in foods & culture. 3 Assessment Depending on the teacher/subject, assessment can vary for this activity. It could be simply observational assessment based on the class discussion at the end of Part 2. Students could write an essay question response over the comparison of the diets on a test or as an “exit” ticket. Bell work on a subsequent day might be a T chart or bubble map comparing the two diets. Modifications In some groups it may be more useful to give them an example of a modern teenager’s diet so that class time can spent working together on Part 1 of this activity. This may help with confusion or those who cannot remember what they ate yesterday. Extension After both parts of the initial lesson are completed, students in upper level courses such as Biology II or Human Anatomy/Physiology may be interested in the diseases of the Ancient Pueblo Indians based on their diets. Using the USDA ChooseMyPlate site as well as other resources, students would determine missing nutrients in the Pueblo diet & then explore possible deficiency diseases based on their findings. Education Standards National Science Education Standards SCIENCE IN PERSONAL AND SOCIAL PERSCPECTIVES, CONTENT STANDARD F As a result of activities in grades 9-12, all students should develop understanding of Personal and community health Population Growth Natural Resources Environmental Quality Natural and human-induced hazards Science and technology in local, national, and global challenges 4 Diets of the Past & Present Part 1: Your Modern Day Diet How healthy do you think you eat? Explain. In the space below, list what you ate yesterday. Try to include the approximate portion sizes. Hints: 1 cup = the size of your fist, 3 oz of meat = size of the palm of your hand, & 1 slice of bread = 1 oz. Breakfast Lunch Dinner Snacks Is this a good representation of what you eat in a normal day? Explain. Now let’s look at your food listed above & see how healthy you ate yesterday. Use the Food Group pages to help you as you place a C in the box with any food that is considered a carbohydrate, an L in any food that contains fat/oil, & a P in the box with any food that is considered a protein food. Most foods should have more than one letter in the box with it. Hint: Grains & Fruits contain carbohydrates, the Protein Group contains Proteins, Lipids can be found in Proteins, Dairy & Grains. 5 Now count them up. How many carbohydrates did you have yesterday? How many were sugars? How many were starches? How many lipids did you have yesterday? How many proteins did you have yesterday? What is considered a healthy diet? According to the new United States Department of Agriculture My Plate dietary guidelines, it says that at each meal half your plate should be filled with fruits & vegetables, one quarter of your plate should be grains (carbohydrate starches) & the last quarter of your plate should be proteins. In addition to this you should have one serving of dairy at each meal. This averages out to about 6 oz of grains, 3 cups of vegetables, 2 cups of fruit, 3 cups of dairy & 6 oz of protein each day. How close were you? Explain. 1. What is the purpose of carbohydrates in your diet? 2. What is the purpose of lipids in your diet? 3. What is the purpose of proteins in your diet? 4.

In the space below, make a table similar to yesterday’s table listing all the foods that the Pueblo Indians ate in one day. Use the Food Group pages to help you as you place a C in the box with any food that is considered a carbohydrate, an L in any food that contains fat/oil, & a P in the box with any food that is considered a protein food. Breakfast Lunch Dinner Snacks Now count them up. How many carbohydrates did the Pueblo Indians eat in the day? How many were sugars? How many were starches? How many lipids did the Pueblo Indians eat in the day? How many proteins did the Pueblo Indians eat in the day? How does this match up with our modern day recommended diet? According to the new United States Department of Agriculture My Plate dietary guidelines, it says that at each meal half your plate should be filled with fruits & vegetables, one quarter of your plate should be grains (carbohydrate starches) & the last quarter of your plate should be proteins. In addition to this you should have one serving of dairy at each meal. This averages out to about 6 oz of grains, 3 cups of vegetables, 2 cups of fruit, 3 cups of dairy & 6 oz of protein each day. How close were the Pueblo Indians? Explain. 9 1. What foods did the Pueblo Indians eat that are not like anything that you might eat? 2. What foods do you eat that are similar to those of the Pueblo Indians? 3. How did your daily diet compare to that of an ancient Pueblo Indian? Explain. 4. Do you think that you could survive on a diet similar to the ancient Pueblo Indians? Explain. 5. From what you know about healthy eating, what kinds of things are missing from their diet? Explain. 10 Pueblo Indians of the Past Mesa Verde is an area found in southwest Colorado & was once the home to ancient Pueblo Indians (once commonly called Anasazi). These Indians inhabited the surrounding area for many years (800-1300 AD). Some lived in pithouse structures, some in Pueblos & some in cliff dwellings for which Mesa Verde National Park is famous. The ancient Pueblo Indians were hunter-gatherers when they first came to the area but with the introduction of maize they became mostly agriculturalists who supplemented their diets with wild plants & animals. As agriculturists what would the Pueblo Indians farm? Most of the farming was corn (maize). This made up 60-80% of their diet & it would require 3-4 acres of corn to supply a family of 4 with food for the year. This would also allow them to store some corn away for years that were not as fruitful. They also grew squash & later beans were added to the list. Beans are high in protein & contain essential amino acids that are absent in corn. This helped Pueblo Indians to form complete proteins in their bodies. Corn could be dried & stored on the cob. Corn kernels were parched in jars that lay on their sides near the fire & then could be ground into flour to be used to make mush. Corn could also be boiled or eaten raw. In terms of hunting, what kinds of things did they eat? When they first moved to the area large game animals such as mule deer were plentiful. As their population numbers increased, this resource was depleted so other animals needed to be hunted for food. These may have included rabbit (both jackrabbit & cottontail) and other rodents such as mice. Rarely would they hunt bison, elk, antelope or bighorn sheep as they were not plentiful in the area year round. Turkeys became an important food source in the 1200s & were eventually domesticated. Fish, amphibians & reptiles are absent from their food refuse piles so may not have been consumed. Males probably ate more meat than women but babies, young children & nursing/pregnant women do need more than normal. Most adults were able to get the protein that they needed from the plant foods that they ate so it wasn’t necessary to have meat every day. Meat was typically roasted, stewed or dried as jerky. There were many wild plants that the Pueblo Indians gathered for eating fresh or storing. Fruits would include elderberry, serviceberry, juniper, nightshade, prickly pear cactus, yucca, holly grape, & chokecherry. Nuts or seeds would be collected from pinyon pines, sunflowers, gambel oak, & rice grass. Vegetable type foods might include the prickly pear cactus pads, greens from goosefoot, purslane, tomatillo, tansy mustard & amaranth (pigweed). Berries were often collected & either eaten fresh or dried for winter. Nuts & acorns could be parched/dried to be saved for later use or ground into flour to be used in making bread or mush. An average family would use about 1 qt of cornmeal per day. This would be about 4 cups of corn per person. This is assuming that wild plants & animals provided additional calories, vitamins/minerals and protein that were missing from the corn. Typically a family would eat twice a day & the father always remembered to make a food offering to the gods by throwing a small amount of food into the fire. A meal might include a stew of basic stock containing chunks of meat (sometimes whole small animals), pieces of vegetables (maybe squash or beans) and flavoring from wild fruits or berries. 11 Works Cited Adams, Karen.

Explain. Varied answers. Students should be able to explain/justify why they think it was a normal day of eating or not. Now let’s look at your food listed above & see how healthy you ate yesterday. Use the Food Group pages to help you as you place a C in the box with any food that is considered a carbohydrate, an L in any food that contains fat/oil, & a P in the box with any food that is considered a protein food. Most foods should have more than one letter in the box with it. Hint: Grains & Fruits contain carbohydrates, the Protein Group contains Proteins, Lipids can be found in Proteins, Dairy & Grains. 13 Now count them up. How many carbohydrates did you have yesterday? 13 (remind students that not all carbohydrates are the same & that some things like milk have minimal carbohydrates) How many were sugars? Approx 5 (milk, fruit, ice cream & cookies) How many were starches? Approx 8 (toast, bread, lasagna noodles, hamburger buns) How many lipids did you have yesterday? Approx 11 (again remind students that the fat content is not the same & some foods are high in fat while others are low) How many proteins did you have yesterday? Approx 6 (milk, peanut butter, meat patty/cheese, lasagna meat/cheese) What is considered a healthy diet? According to the new United States Department of Agriculture My Plate dietary guidelines, it says that at each meal half your plate should be filled with fruits & vegetables, one quarter of your plate should be grains (carbohydrate starches) & the last quarter of your plate should be proteins. In addition to this you should have one serving of dairy at each meal. This averages out to about 6 oz of grains, 3 cups of vegetables, 2 cups of fruit, 3 cups of dairy & 6 oz of protein each day. How close were you? Explain. Varied answers. Students should be able to explain/justify how their daily intake compared to 6 oz grains, 3 cups vegetables, 2 cups fruit, 3 cups dairy & 6 oz of proteins. For Sample Data: 6+ oz of grains with the toast, bun, fries, bread & pasta 2 cups of vegetables with the salad & green beans 1.5 cups of fruit with the banana & pineapple 3+ cups of dairy with the milk, cheese, & ice cream ~6 oz of protein with the peanut butter, meat patty & lasagna meat 1. What is the purpose of carbohydrates in your diet? Energy 2. What is the purpose of lipids in your diet? Cell membrane formation, hormones, energy storage 3. What is the purpose of proteins in your diet? Hormones, enzymes, structural 4. Why do you need dairy foods? Besides supplying protein, carbohydrates & lipids dairy foods also provide calcium for strong bones. 5. What about all those vegetables & fruit? Why do you need to eat them? Besides supplying carbohydrates in small amounts, these foods provide lots of vitamins & minerals as well as much needed fiber for our diets. 14 Diets of the Past & Present (Answer Key) Part 2: Ancient Pueblo Indian Diet Read the description of the Pueblo Indians of the past on the attached page. In the space below, make a table similar to yesterday’s table listing all the foods that the Pueblo Indians ate in one day. Use the Food Group pages to help you as you place a C in the box with any food that is considered a carbohydrate, an L in any food that contains fat/oil, & a P in the box with any food that is considered a protein food. Sample Data Breakfast Lunch Dinner Snacks 1 cup corn mush C, P 1 cup Stew (rabbit meat, squash, beans, corn) C, P, L ½ cup berries C Now count them up. How many carbohydrates did the Pueblo Indians eat in the day? Maybe 4 How many were sugars? 1 How many were starches? 3 How many lipids did the Pueblo Indians eat in the day? Maybe 1 How many proteins did the Pueblo Indians eat in the day? Maybe 2 How does this match up with our modern day recommended diet? According to the new United States Department of Agriculture My Plate dietary guidelines, it says that at each meal half your plate should be filled with fruits & vegetables, one quarter of your plate should be grains (carbohydrate starches) & the last quarter of your plate should be proteins. In addition to this you should have one serving of dairy at each meal. This averages out to about 6 oz of grains, 3 cups of vegetables, 2 cups of fruit, 3 cups of dairy & 6 oz of protein each day. How close were the Pueblo Indians? Explain. Students should realize that the Pueblo Indians ate much less than we do today. Although this is just an estimate they should still be able to picture the Indian diet. 15 1. What foods did the Pueblo Indians eat that are not like anything that you might eat? Some of the greens like goosefoot & purslane. Some of the fruits like yucca, serviceberry, juniper & cactus. Meats like mice & bighorn sheep. 2. What foods do you eat that are similar to those of the Pueblo Indians? Corn, beans, squash, turkey, sunflower seeds, and rabbit, elk, & bison for some. 3. How did your daily diet compare to that of an ancient Pueblo Indian? Explain. Vary but students should realize that they eat at least twice as much as the Indians & that Indians did not eat 3 times a day plus snacks. Americans today also tend to eat more protein & fewer veg/fruits than the Indians. Indians also did not have a daily source of calcium such as milk. 4. Do you think that you could survive on a diet similar to the ancient Pueblo Indians? Explain. Vary but students should be able to justify why or why not they could eat like a Pueblo Indian. 5. From what you know about healthy eating, what kinds of things are missing from their diet? Explain. Vary Fats/oil (lipids), many vitamins/minerals such as vitamin C, calcium, iron, etc, excess sugars 16
