Students learn that fats found in the foods we eat are not all the same; they discover that physical properties of materials are related to their chemical structures. Provided with several samples of commonly used fats with different chemical properties (olive oil, vegetable oil, shortening, animal fat and butter), student groups build and use simple LEGO MINDSTORMS(TM) NXT robots with temperature and light sensors to determine the melting points of the fat samples. Because of their different chemical structures, these fats exhibit different physical properties, such as melting point and color. This activity uses the fact that fats are opaque when solid and translucent when liquid to determine the melting point of each sample upon being heated. Students heat the samples, and use the robot to determine when samples are melted. They analyze plots of their collected data to compare melting points of the oil samples to look for trends. Discrepancies are correlated to differences in the chemical structure and composition of the fats.

In this decision case, a congressional staffer must weigh a number of competing concerns and issues, including popular reactions to genetically modified organisms, in deciding how to present information to her boss, an influential congressman drafting legislation to support agricultural research. The case explores the social and biological issues surrounding micronutrient malnutrition, including deficiencies of several vitamins and essential minerals, especially iron, iodine, and vitamin A, which affect at least one-third of the world's population, primarily in developing nations. Developed for a graduate-level seminar on "Genomics, Agriculture, Food Systems and Development," the case teaches about the issues surrounding genomic applications in agriculture and their implications to health, environmental stewardship, economic sustainability, and national development.

This case is a "clicker" adaptation of a similarly titled case by Merle Heidemann and Gerald Urquhart of Michigan State University, "A Can of Bull?" The story introduces students to basic principles of metabolism and energy through a biochemical analysis of commonly available "energy drinks" that many students purchase at relatively high prices. Students learn to define energy in a biological/nutritional context, identify valid biochemical sources of energy, discuss how foods are metabolized to generate ATP, and critically evaluate marketing claims for various energy drinks. The case can be used in introductory level courses to introduce these principles or as a review of basic biochemistry and nutrition for upper-level students in nutrition, physiology, or biochemistry courses. The case is presented in class using a PowerPoint (~2.3MB) that is punctuated by multiple-choice questions students answer using personal response systems, or "clickers."

When Mitchell reveals that he is going on a low-carb diet, Janine tries to talk him out of it, telling him that he's too thin as it is and doesn't need to loose any weight. Designed to accompany a nonmajors unit on human anatomy and physiology, this interrupted case study has students applying what they learn about human body systems to Mitchell's fad diet claims and Janine's sharp criticisms. Supplementary links help students explore new discoveries about appetite-controlling hormones, how body image may influence people's dietary decisions, and some of the most common diet myths.

Few people are aware of how crucial the sense of smell is to identifying foods, or the adaptive value of being able to identify a food as being familiar and therefore safe to eat. In this lesson and activity, students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. The teacher leads a discussion that allows students to explore why it might be adaptive for humans and other animals to be able to identify nutritious versus noxious foods. This is followed by a demonstration in which a volunteer tastes and identifies a familiar food, and then attempts to taste and identify a different familiar food while holding his or her nose and closing his or her eyes. Then, the class develops a hypothesis and a means to obtain quantitative results for an experiment to determine whether students can identify foods when the sense of smell has been eliminated.

There is much controversy and anecdotal information about popular diets and dietary supplements, but all too often little scientific or controlled clinical data. We examine the science behind normal mechanisms of weight control, and how weight loss diets are constructed and work. The aim of the course is to acquire the knowledge to critically appraise a weight control diet or dietary supplement and choose the best plan for success, both in the short-term and the long run. Students taking the actual class will, in addition to learning the lecture material presented here, complete in-class assignments where they choose a popular diet or supplement, research the scientific literature on this diet/supplement, and present a critical appraisal of its validity and efficacy.

In the first part of the activity, each student chews a piece of gum until it loses its sweetness, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount of sugar in the gum, and can be compared to the amount stated on the package label. In the second part of the activity, students work in groups to design and conduct new experiments based on questions of their own choosing. These questions arise naturally from observations during the first experiment, and from students' own experiences with and knowledge of the many varieties of chewing and bubble gums available.

There are various hormones that influence the structure of the skin. These influences may be made apparent by the repeated long-term administration of various glucocorticoids or their analogues. Endogenous imbalances are generally seen in adult mature animals although congenital forms have been seen, especially with hypothyroidism. The hormones implicated as important for maintaining skin structure are thyroxine, cortisol and estradiol. Deficiencies or excessive production may result from abberations in the function of the hypothalamic-adrenal axis, the adrenal gland, thyroid gland or the gonads.

Civilization is mostly the story of how seeds, meats, and ways to cook them travel from place to place. - Adam Gopnik, "What's Cooking" "A significant part of the pleasure of eating is in one's accurate consciousness of the lives and the world from which food comes." - Wendell Berry, "The Pleasures of Eating" If you are what you eat, what are you? Food is at once the stuff of life and a potent symbol; it binds us to the earth, to our families, and to our cultures. The aroma of turkey roasting or the taste of green tea can be a portal to memories, while too many Big Macs can clog our arteries. The chef is an artist, yet those who pick oranges or process meat may be little more than slaves. In this class, we will explore many of the fascinating issues that surround food as both material fact and personal and cultural symbol. We will read essays by Chang-Rae Lee, Francine du Plessix Gray, M. F. K. Fisher, Anthony Bourdain, and others on such topics as family meals, the art and science of cooking, fair trade, eating disorders, and food's ability to awaken us to "our own powers of enjoyment" (M. F. K. Fisher). We will also read Eric Schlosser's Fast Food Nation and view one or more films or videos as a class. Assigned essays will grow out of memories and the texts we read, and will include personal narratives and essays that depend on research. Workshop review of writing in progress and revision of essays will be an important part of the course.
