Human Nutrition, Foods, and Exercise

Overview

Nutrition, foods, and exercise science is a unique field of study that builds on the biological and physical sciences. Human nutrition is directed toward helping people choose food that meets their physiological needs and is consistent with their lifestyles and cultural preferences. Changes in lifestyle and food consumption patterns have created consumer demand for new food products that are shelf stable, require little or no preparation, and are appropriate in nutrition content. These trends have increased the need for food professionals who wish to apply their science background to exploring the nutrient content and chemical and physical properties of foods and food ingredients. Increasing interest in physical fitness and wellness has brought about new professional opportunities in assisting people who want to develop appropriate exercise patterns and make healthy changes in their lifestyle.

Many contemporary health issues including obesity, heart disease, and cancer have been associated with a person's food intake and level of exercise. This has led to increasing emphasis on health promotion and disease intervention, and the nutrition and exercise professionals are integral members of the health care team. Expanding research by private and government agencies focusing on the role of nutrition and physical activity in health, growth, and aging has created a demand for graduates at the B.S., M.S., and Ph.D. levels who have a background and interest in laboratory and experimental methods in nutrition, foods and exercise science. The current interest in physical performance in our society has broadened the opportunities for combining expertise in nutrition with exercise and fitness for those with skills in counseling and entrepreneurship. Individuals with a background in food and nutrition are needed to help solve the problems of world hunger and food shortages, and the accompanying loss of human potential.

There are two options from which an undergraduate student majoring in human nutrition, foods and exercise may choose: Dietetics or Science of Food, Nutrition and Exercise.

The department participates in the University's Honors Program (see "Academics" in this catalog).

The Department of Human Nutrition, Foods, and Exercise at Virginia Tech offers Master’s and Doctoral degrees in three specialized areas as they relate to nutrition, physical activity, and health. Graduate students may earn a M.S. or a Ph.D. with an emphasis in Molecular and Cellular Science, Clinical Physiology and Metabolism, or Behavioral and Community Science.

Dietetics

Consult: Heather K. Cox

The undergraduate Dietetics option, known as the Didactic Program in Dietetics (DPD), leads to a Bachelor of Science degree in Human Nutrition, Foods and Exercise. The dietetics option fulfills all academic course requirements for a Didactic Program in Dietetics according to the Standards of Education per the Accreditation Council for Education in Nutrition and Dietetics (ACEND). ACEND is the accrediting arm of the Academy of Nutrition and Dietetics. Following completion of the B.S. degree, a student has earned an ACEND Verification Statement.  A student must then complete a supervised practice program (Dietetic Internship) to be eligible for the Registration Examination (RD) for Dietitians. The supervised practice requirement can be met through any ACEND accredited dietetic internship. Graduates with the B.S. in Dietetics are eligible to apply for the department's, or other, accredited Dietetic Internships.

Registered Dietitians work in a variety of work settings. The dietetics program prepares you to assume a professional role in health care, research, the business environment or to pursue graduate studies. The dietetics program ultimately prepares you to assume a professional role in a health care, research, or business setting or to go on to graduate school. Clinical dietitians in hospitals and out-patient clinics provide care to individuals with disease-related nutritional problems. Community dietitians may work in health clubs specializing in sports nutrition, in work site wellness programs, or in community programs serving mothers and children, low-income families, or elderly people. Others work for food companies dealing with consumer questions about the nutrient content of food products, or with companies manufacturing nutritional supplements or other medical or health products. Administrative Dietitians with management or business interests find positions in food service management in health care facilities, work site, college, or university food service, or hotels and resorts. Registered Dietitians counsel people of all ages, cultural and ethnic backgrounds, and levels of education.

Students in the Dietetics option must maintain an overall GPA of 3.0 to remain in this option. Students who want to change their major into the Dietetics option with HNFE must have an overall GPA of 3.0. Please see the Satisfactory Progress section for additional requirements.

Science of Food, Nutrition, and Exercise

Consult: Renee Selberg-Eaton

Upon completion of this option a student is well prepared for graduate work in any area of nutrition, exercise physiology or related sciences. This option also meets most admission requirements for medical, dental, physical therapy, pharmacy, physician assistant, athletic training and other health professions programs. This option allows students flexibility to tailor the degree toward long term goals which may lead to employment opportunities in research and development with a company manufacturing nutritional, health and exercise, or medical products, in the food industry in food product testing or quality control, in the health and fitness industry, or in a position related to clinical exercise physiology. Students in this option gain knowledge, skills, and abilities specified by the American College of Sports Medicine for certification as a Certified Health Fitness Specialist. With the growing attention to the role of nutrition and exercise in health promotion and disease prevention, this option is especially appropriate for the student preparing for a career in medicine, physical therapy, or a related health field. The majority of students in the Science of Food, Nutrition and Exercise option plan to attend graduate or professional school.

Students in the SFNE option do not meet the ACEND requirements for a degree in dietetics and therefore do not earn a Verification Statement. Students may choose to earn both the Dietetics and SFNE options in the department.
