Dr. Colleen Spees, co-author of Wardlaw’s Contemporary Nutrition, leads research efforts at this unique living laboratory that provides cancer survivors and food-insecure families the opportunity to incorporate a Farm-to-Fork approach while harvesting fruits, vegetables, and herbs throughout the growing season. Tomatoes, like those pictured on the front cover, are considered a “functional food” because they provide health benefits beyond the essential nutrients they contain. Vitamin C and lycopene, a phytochemical in tomatoes, function as powerful antioxidants. Lycopene has also been linked to a reduced risk of stroke, some eye diseases, and certain types of cancer. Tomatoes are also abundant sources of potassium, a mineral often lacking in the American diet. A dietary pattern rich in potassium and low in sodium can lower blood pressure and reduce the risk of heart disease. Nutrients and phytochemicals in tomatoes may also boost the immune system and protect bone health. The eleventh edition of Wardlaw’s Contemporary Nutrition shows how a primarily plant-based eating pattern—rich in nutrients and phytochemicals—works to support and maintain optimal health throughout life. The new Farm to Fork feature in each chapter outlines the best ways to grow, shop, store, and prepare specific fruits and vegetables to ©Briana Zabala optimize their nutritional value. This comprehensive and evidence-based perspective on The authors, Anne Smith, Colleen Spees, nutrition makes learning fun, engaging, and relevant. and Angela Collene at the Garden of Hope. iii smi09965_fm_i-xxvii.indd iii 10/06/17 02:36 PM Final PDF to printer Dear Students, Welcome to the fascinating world of nutrition! Because we all eat several times a day and the choices we make can have a dramatic influence on health, nutrition is our favorite area of science. At the same time, though, the science of nutrition can seem a bit confusing. One reason for all the confusion is that it seems like “good nutrition” is a moving target; different authorities have different ideas of how we should eat, and nutrition recommendations sometimes change! Do carbohydrates cause weight gain? Do I need to limit saturated fat? Should we eat foods that contain gluten? Second, there are so many choices. Did you know that the average supermarket carries about 40,000 food and beverage products? The manufacturers of all those products are vying for your attention, but typically, the most aggressively marketed items are not the healthiest. How can you identify a healthy product? Third, as a nation, we eat many of our meals and snacks away from home. When we eat foods someone else has prepared for us, we surrender control over what is in our food, where the food came from, and how much of it goes on our plates. Undoubtedly, you are interested in what you should be eating and how the food you eat affects you. Wardlaw’s Contemporary Nutrition is designed to accurately convey changing and seemingly conflicting messages to all kinds of students. Our students commonly have misconceptions about nutrition, and many have a limited background in biology or chemistry. We teach complex scientific concepts at a level that will enable you to apply the material to your own life. This marks the eleventh edition of Wardlaw’s Contemporary Nutrition. We are very excited to introduce you to our newest author, Dr. Colleen Spees! Like our other authors, she is a Registered Dietitian Nutritionist, which means she will help you to translate nutrition science into practical advice. At The Ohio State University, Dr. Spees is a valued expert on cancer, nutritional genomics, and food security. We are thrilled to add her unique perspective and contemporary ideas. As in previous editions, we have written this book to help you make informed choices about the food you eat. We will take you through explanations of the nutrients in food and their relationship to health and make you aware of the multitude of other factors that drive food choices. To guide you, we refer to many reputable research studies, books, policies, and websites throughout the book. With this information at your fingertips, you will be well equipped to make your own informed choices about what and how much to eat. There is much to learn, so let’s get started!

SmartBook heat maps provided a quick visual snapshot of usage of portions of the text and the relative difficulty students experienced in mastering the content. With these data, we were able to hone not only our text content but also the SmartBook probes. With the eleventh edition of Wardlaw’s Contemporary Nutrition we remember its founding author, Gordon M. Wardlaw. Dr. Wardlaw had a passion for the science of nutrition and the research that supports it and demonstrated an exceptional ability to translate scientific principles into practical knowledge. This skill is what made his book truly “contemporary.” He was tireless when it came to staying current and relevant to a changing world. It has been a privilege for all of us to join Dr. Wardlaw as coauthors of this textbook. For Anne Smith, he was an extraordinary colleague, mentor, and friend. Angela Collene was blessed to have been one of his graduate students at The Ohio State University, when she first began to assist with revisions to his books. Colleen Spees was a student in Dr. Wardlaw’s first nutrition class at The Ohio State University and now holds his previous tenure-track position. Like so many other students, colleagues, and friends, we remember Dr. Wardlaw as a source of vast knowledge, good humor, and inspiration. The best way we know to honor our dear friend and mentor is to carry on his legacy of outstanding textbooks in introductory nutrition. Wardlaw’s Contempo- rary Nutrition will continue to evolve and reflect current trends and breakthroughs in nutrition science, but Dr. Wardlaw’s fingerprints will remain on every page. vii smi09965_fm_i-xxvii.indd vii 10/06/17 02:36 PM Final PDF to printer McGraw-Hill Connect® is a highly reliable, easy-to- use homework and learning management solution that utilizes learning science and award-winning adaptive tools to improve student results.
