BIO 127IN - Human Nutrition and Biology

4 Credits, 6 Contact Hours
3 lecture periods 3 lab periods

Principles of nutrition presented in the context of human biology. Includes chemistry, digestion, absorption, and metabolism of nutrients. Also includes biological and nutritional perspectives on various health issues such as cardiovascular disease, hypertension, cancer, diabetes, and osteoporosis, including genetic and epigenetic effects. Also covers analysis of scientific studies relating to nutrition.

Gen-Ed: Meets AGEC - SCI; Meets CTE - M&S.

Course Learning Outcomes
  1. Describe the nutritional and physiological importance of each of the following nutrients: carbohydrates, fats, protein, vitamins, minerals and water.
  2. Understand how nutrition affects health in terms of developing and/or preventing chronic diseases including obesity, cardiovascular disease, diabetes, liver disease, kidney disease and cancer.
  3. Demonstrate proficiency in conducting experiments in nutrition and biology.

Performance Objectives:
  1. Demonstrate improvement in the general education goals of communication and critical thinking.
  2. Evaluate the design, results, and conclusions of various nutritional studies.
  3. Explain the purpose and significance of dietary recommendations.
  4. Describe the biology of human digestion and absorption in general, as well as the nutritional, metabolic, and physiological significance of carbohydrates, proteins, amino acids, lipids, vitamins, major minerals, trace elements, and non-nutrient substances.
  5. Describe several nutrient-nutrient and drug-nutrient interactions.
  6. Elaborate on basic aspects of clinical nutrition, and various nutrition related issues.
  7. Describe how nutrient needs change during human development from the embryonic period through adulthood, along with the nutritional needs during pregnancy and lactation.
  8. Evaluate the tendencies and risks associated with genetic and epigenetic effects on nutrition and health.
  9. Competently analyze diets applying principles learned in this course using either food composition tables or dietary analysis software.
