Areas of Concentration:

  • Nutrition education and awareness
  • Food as medicine
  • Alternative medicine
  • Evolution of the human diet
  • Ancestral nutrition
  • Gut physiology and the microbiota
  • Human milk and dairy foods
  • Infant diets
  • Weaning diets
  • Immunology
  • Autism spectrum disorders


Research / Interests:
I am extremely passionate about controversies in nutrition science and teaching basic science methods to students. I think it is very important to develop critical thinking skills to be able to decipher nutrition information for yourself, rather than trusting someone else’s opinion. I am also interested in gut physiology and the idea of the gut as the root of health. Many disease states originate in the gut and cause problems throughout the body. Therefore, our food choices involve much more than simply meeting nutrient requirements. We need to consider the evolution of the human diet to determine which foods our species is adapted to eat. The mismatch between the modern diet and our ancestral genome is the cause of many chronic diseases.

Human Nutrition: The Science of Healthy Living, 3rd Edition

Human Nutrition: Science for Healthy Living has been developed by a team of nutrition educators who have extensive college teaching experience and a passion for teaching relevant, student-centered nutrition, biology, health, and wellness courses. Our goals with this textbook are to teach students the science of nutrition while also preparing future healthcare professionals and to make the study of introductory human nutrition enjoyable.


Learning about any science can be challenging if the information is not presented in an appealing, interesting manner. We've made a distinct effort to write the content of this book in an understandable way and to provide clear descriptions of concepts that can be difficult to convey, such as the processes of digestion, absorption, and energy metabolism.

The authoring team had a vision of writing an interesting, engaging, and evidence–based introductory nutrition textbook that has a wide variety of pedagogical features to promote active learning. To that end, this third edition of Human Nutrition: Science for Healthy Living is learner-centered, easy to read, and richly illustrated with figures and images that clearly show physiological processes. Furthermore, the author team felt students and faculty would appreciate a textbook that was clinically oriented and provided ample opportunities for students to practice using their nutrition knowledge and critical thinking skills. Human Nutrition: Science for Healthy Living is the result of a team of authors with extensive teaching experience and who currently teach introductory nutrition. The clinical emphasis of the textbook is of particular relevance to those studying nutrition, dietetics, or other health science professions, including nursing. Specific real-life examples, current statistics, and scientific evidence from professional resources are provided to support nutrition concepts. Features designed to attract students' interest, such as Sustainability and Your Diet, Did You Know? and Fresh Tips boxes, provide up-to-date information on current and sometimes controversial topics, as well as practical recommendations for everyday healthy living.



Human Nutrition: Science for Healthy Living provides the framework for students to learn how nutrition information is often interrelated and to apply the science of nutrition to clinical situations. Furthermore, students apply key scientific principles and knowledge that they can translate into their own lives.


Human Nutrition: Science for Healthy Living was written by authors who have extensive experience teaching introductory nutrition classes to both majors and nonmajors. The authors recognize the diverse learning needs of today's students and how the modern learning environment in higher education—large lecture classes, online classes, and flipped/hybrid classrooms—often challenge even the most experienced nutrition educators. The textbook and its supportive interactive materials are designed to help instructors create a learner-centered teaching environment that maximizes student engagement and knowledge acquisition. This current, evidence-based introductory textbook has a wide variety of pedagogical features to promote active learning among students.
