Job Description

Dietitians are essential in designing nutrition programs to protect a patient's health, alleviate the symptoms of some types of diseases, and to prevent allergic reactions. Dietitians have a wide host of responsibilities and tasks that come with their job, as they are largely responsible for becoming experts in the use of food and nutrition in a person's daily life and their pathway to recovery from sickness or an unhealthy lifestyle. Food plays a massive role in our bodies, and we can often forget just how much of a role it plays in our health and our treatment plan.

Dietitians are the experts in the healthcare industry when it comes to understanding the importance of nutrition as the foundation of good health, from conception to old age. Even more important, is understanding how our dietary needs and nutritional needs change throughout our lives. Our bodies behave very differently from when we're children to seniors, and Dietitians are responsible for understanding those changes and the steps we can take to set ourselves up for a healthy lifestyle moving forward.

A Dietitian is responsible for assisting patients with all the tools they need to abide by healthy eating practices, maintain a healthy lifestyle, and manage lifetime diseases or illnesses that they might have through proper nutrition.

The next part of a Dietitian's job description is to educate and advise patients about what they should be eating and the importance of eating properly. Dietitians are responsible for making sure that their patients understand why eating healthy is important. Often we've been told throughout time and grade school that we need to eat well, and we believe that we're making educated decisions with our daily meals. But we don't quite realize what we're eating until we track it and then present it to a Dietitian.

Dietitians can work with a variety of patients in several different ways. Their environment and setting will often determine what kind of work they do and the responsibilities they have. Dietitians can work with a variety of patients in a clinical setting or tailor their specialization to something more narrow in scope like the following. Clinical Dietitians may specialize in one or more of the following areas:

  • Management of overweight patients

  • Nutritional needs of critically ill patients

  • Dietary demands of patients with kidney disease and diabetes

  • Management of food service departments in areas such as nursing care facilities, small hospitals or correctional facilities

Depending on specialty and their workplace, a Dietitian can have a wide array of duties that they are responsible for on a regular basis as well. Some of the most common roles that a Dietitian can have often depends on the industry or segment they're working in. Some of the most common Dietitian industry roles they can occupy include:

• Research Dietitian

The next role that Dietitians can often find themselves in is being a Research Dietitian. Research Dietitians are focused on conducting additional nutritional and dietary science that can illuminate some questions that the industry might have.

• Pharmaceutical Dietitian

Dietitians can work in a variety of roles and their responsibilities might differ slightly in each, but there are some common responsibilities that you can expect to perform as a Dietitian throughout your career. We've outlined the main responsibilities that a Dietitian has below.



Dietitians focus their attention on the impact that food has on our health. They most commonly provide medical nutrition therapy for patients in hospitals and nursing care facilities.

As a member of the health care team, a Dietitian is responsible for assessing the nutritional needs of patients, developing and implementing nutritional programs, and evaluating and reporting on the results of these interventions. Dietitians work in consultation with doctors and other health care professionals to coordinate dietary needs and medical requirements for each patient.

The first key responsibility that a Dietitian has is to assess a patient's health needs. The best way for a patient to start getting on the pathway to a healthy lifestyle is through proper nutrition. Dietitians are responsible for evaluating a patient's nutritional needs and how it is contributing to their overall well-being by conducting thorough nutritional assessments that are designed to get a baseline for other healthcare professionals to use.

Plenty of healthcare problems and ailments can be solved by cleaning up a patient's diet. We often don't realize how detrimental our nutrition is, but it's important to remember that our diet is what fuels our body. You wouldn't put bad gas in your car, and you shouldn't do the same thing for your body. A Dietitian's main responsibility is to conduct this thorough assessment and evaluate what kind of nutrition a patient has and evaluate whether or not that is the culprit behind what they're suffering from.

The next job responsibility that Dietitians have is to create customized meal plans for their patients. Sometimes a customized meal plan is what is necessary to help a patient get the nutrition they need to get on the pathway to a healthy lifestyle. Creating a customized meal plan allows for patients to have a list of foods they can eat and foods they should stay away from. This regimented lifestyle is something that can help guide them on the path to learning which foods are healthy and which foods are unhealthy.

Sometimes we think certain foods are healthy and we make them a staple of our diet, only to realize that they're compounding the issues we already have. Getting on a regimented meal plan that has been written up from a Dietitian is one of the best things that an unhealthy patient can do, because they know that they're going to get all the macro and micronutrients they need to get back to living a healthy lifestyle. Some of the other benefits associated with meal plans for patients include learning portion control, avoidance of wasting food, and saving both money and time.

Once a Dietitian has crafted a meal plan for a patient, the next responsibility they have is to track a patient's progress with following that meal plan. Meal plans aren't any good if the patient elects not to follow them. Dietitians will check in with their patients or do routine follow-ups to evaluate how well they're following their meal plan, make sure they're keeping a recorded log of what they're eating and when, and then ask them what they think about the meal plan. This portion of the follow-up is a dialogue back and forth to evaluate if they'd like to see some changes to the meal plan, if they'd prefer one food over another, etc.

When a patient doesn't mention anything about their meal plan or attempts to skirt the issue, then it tends to cause some alarms for Dietitians because it might mean they're not following it. Following a recommended diet plan and meal plan is often a collaborative process. Dietitians aren't going to always get it right the first time because patient preferences have to be taken into consideration, and that develops over time as the dialogue continues. A patient who is working with the Dietitian and collaborating with them will often stick to their meal plan more closely.

The next responsibility that Dietitians have is to assist with the education and promotion of healthy eating practices. One of the main responsibilities of helping patients achieve a healthier lifestyle is by making sure that they understand the importance of following the recommended meal plan and understand why good nutrition is important. Dietitians can spend dozens of hours with a patient but if the patient doesn't understand that what they're recommending or what the importance is, then they won't be obligated to follow their recommendations, that's why this responsibility is so important for each Dietitian.

Part of this responsibility also involves helping patients understand the health issues that might arise from poor nutrition. Sometimes a patient will ignore the advice of their caregivers but could be prompted to do otherwise if they understood the effects of ignoring sound advice and recommendations.

The next responsibility that Dietitians have in their role is to stay up to date with the latest nutritional and dietary science. In the healthcare industry, nearly every professional needs to ensure that they're using the most up-to-date methodology, providing the most up-to-date knowledge and recommendations to their patients. Dietitians are responsible for continuing their education and staying up to date by completing continuing education credits and courses. Dietitians are responsible for participating in a variety of continuing education activities and completing requirements.

The next responsibility that Dietitians have is to counsel and answer any questions that the patient or the patient's family member might have. Sometimes this involves educating patients about confusing topics as we mentioned above, and other times it'll involve educating a patient's family members about the importance of teamwork when it comes to getting their family members on a proper meal plan.

It's always easier to switch up a routine when you have family and friends who can help you make more informed decisions and promote smart meal choices. Questions are bound to come up and some of the most common questions that Dietitians should expect to answer include ones like, "Is this really necessary?", "What happens if they don't change their diet?", and "How often do we have to stick to this meal plan?".

The next thing that a Dietitian is responsible for is keeping accurate patient records and patient data. This is an important piece of a Dietitian's day because tracking a patient's progress because they're tasked with changing their diet and their nutritional habits start with what they're tracking themselves. If a patient isn't tracking their eating habits and taking notes, it can be quite difficult to adjust the meal plan or nutritional guidelines as you go along.

For those patients that are following their recommended guidelines and are keeping terrific notes, a Dietitian will then use that data to create statistical reports and measurements to track their progress. These statistical reports are then used by Dietitians to showcase their growth from the starting point and evaluate their progress over time. In addition, Dietitians might take these statistical reports to their supervisors and showcase how well certain healthy eating and nutritional meal plans are working out.

Some of the individual responsibilities will also vary greatly depending on the role they're in like we've mentioned previously. We've outlined some of the key responsibilities that certain roles will have as well below.

Community Registered Dietitians (RD) develop nutrition programs that target particular groups of people to promote health and prevent disease. RDs who work as Community Dietitians may be employed in settings such as fitness centers, public health clinics, home health agencies or corporate wellness programs.

When working in home health agencies or corporate wellness programs, Dietitians provide instruction on grocery shopping and food preparation. Many Dietitians focus on the education of the elderly or individuals with special needs and children.

Increased public awareness of the importance of nutrition has led to employment opportunities in areas such as food manufacturing, marketing, and advertising.

Dietitians working in these areas are generally responsible for analyzing foods, preparing literature for public distribution, or reporting on issues such as the nutritional value of recipes, the amount of dietary fiber a food contains, or the efficacy of vitamin supplements.

Dietitians in management roles oversee large-scale meal planning and the preparation of meals in health care facilities, in company cafeterias, in prisons, and in schools. These Dietitians also hire, train and supervise other Dietitians and food service employees.

They are responsible for budgeting for and purchasing food, dietary equipment and necessary supplies. They must enforce sanitary and safety regulations, and prepare expected records and reports. Some Dietitians work under contract as consultants with health care facilities or in their own private practice.

These Dietitians perform nutritional assessments for their clients and give them advice about diet-related concerns, such as weight loss or cholesterol reduction.

Other Dietitians find employment in wellness programs, supermarkets, sports teams and other businesses related to nutrition.

They often consult with food service managers to provide expertise in safety procedures, sanitation, budgeting, menu development, and planning.
