Dietitians and nutritionists plan food and nutrition
programs, and supervise the preparation and serving of meals. They promote healthy
eating habits and suggesting diet modifications, such as less salt for those
with high blood pressure or reduced fat and sugar intake for those who are overweight.
Dietitians run food service systems for institutions
such as hospitals and schools, promote sound eating habits through education
and conduct research. Major areas of practice include clinical, community, management
and consultant dietetics.
Clinical dietitians provide nutritional services
for patients in institutions such as hospitals and nursing homes. They assess
patients' nutritional needs, develop and implement nutrition programs, and evaluate
and report the results. They also confer with doctors and other health-care
professionals to coordinate medical and nutritional needs. Some clinical dietitians
specialize in the management of overweight patients, care of the critically
ill, or of kidney and diabetic patients. In addition, clinical dietitians in
nursing homes, small hospitals or correctional facilities also may manage the
food service department.
Community dietitians counsel individuals and groups
on nutritional practices designed to prevent disease and promote good health.
Working in places such as public health clinics, home health agencies and health
maintenance organizations, they evaluate individual needs, develop nutritional
care plans, and instruct individuals and their families. Dietitians working
in home health agencies provide instruction on grocery shopping and food preparation
to the elderly, individuals with special needs and children.
Increased interest in nutrition has led to opportunities
in food manufacturing, advertising and marketing, in which dietitians analyze
foods, prepare literature for distribution or report on issues, such as the
nutritional content of recipes, dietary fiber or vitamin supplements.
Management dietitians oversee large-scale meal planning
and preparation in health-care facilities, company cafeterias, prisons and schools.
They hire, train and direct other dietitians and food service workers; budget
for and purchase food, equipment and supplies; enforce sanitary and safety regulations;
and prepare records and reports.
Consultant dietitians work under contract with health
care facilities or in their own private practice. They perform nutrition screenings
for their clients and offer advice on diet-related concerns, such as weight
loss or cholesterol reduction. Some work for wellness programs, sports teams,
supermarkets and other nutrition-related businesses. They may consult with food
service managers, providing expertise in sanitation, safety procedures, menu
development, budgeting and planning.
Most dietitians work a regular 40-hour week, although
some work weekends. Many dietitians work part time. Many dietitians and nutritionists
are on their feet for much of the workday.
Training and qualifications
High school students interested in becoming a dietitian
or nutritionist should take courses in biology, chemistry, mathematics, health
and communications. Dietitians and nutritionists need at least a bachelor's
degree in dietetics, foods and nutrition, food service systems management or
a related area. College students in these majors take courses in foods, nutrition,
institution management, chemistry, biochemistry, biology, microbiology and physiology.
Other suggested courses include business, mathematics, statistics, computer
science, psychology, sociology and economics.
Twenty-seven of the 41 states with laws governing
dietetics require licensure, 13 require certification and one requires registration.
The Commission on Dietetic Registration of the American Dietetic Association
(ADA) awards the Registered Dietitian credential to those who pass a certification
exam after completing their academic coursework and supervised experience. Because
practice requirements vary by state, interested candidates should determine
the requirements of the state in which they want to work before sitting for
any exam.
Job outlook
Employment of dietitians is expected to grow about
as fast as the average for all occupations through 2010 as a result of increasing
emphasis on disease prevention through improved dietary habits. A growing and
aging population will increase the demand for meals and nutritional counseling
in nursing homes, schools, prisons, community health programs and home health
care agencies.
The number of dietitian positions in hospitals is
expected to grow slowly as hospitals continue to contract out food service operations.
But employment is expected to grow fast in contract providers of food services,
social services agencies and offices and clinics of physicians.
Employment growth for dietitians and nutritionists
may be somewhat constrained by some employers substituting other workers, such
as health educators, food service managers and dietetic technicians. Growth
also is constrained by limitations on insurance reimbursement for dietetic services.
Earnings
Dietitians and nutritionists held about 49,000 jobs
in 2000. More than half were in hospitals, nursing homes or offices and clinics
of physicians. Median annual earnings of dietitians and nutritionists were $38,450
in 2000. Median annual earnings in hospitals, the industry employing the largest
numbers of dietitians and nutritionists, were $39,450.
