Dr. Thomson, can you explain the difference between a dietitian and a nutritionist, and why it’s important for patients to seek out the appropriate person, maybe in their cancer center and oncology dietitian when receiving care for cancer?
Dr. Cynthia Thomson:
Yeah. Definitely. So a registered dietitian, or what we call an RD, similar to a registered nurse, RN, right, they have had a four-year undergraduate degree that is extremely heavy in the sciences, chemistry, biochemistry, physiology. They understand how nutrients are metabolized and how the body processes nutrients to optimize health. In addition, after all of that four-year degree, which is pretty much equivalent to a pre-med degree, they will then go through an internship where they’re supervised by professionals in the field and spend quite a bit of time in the clinics with patients, learning the day-to-day application of all that knowledge that they’ve learned. It’s a five-year commitment for most individuals.
And then they have to pass a registration exam. And then on top of that, they have to stay up-to-date in terms of continuing education, right? They can’t just walk away and then for the next 30 years practice nutrition without being up-to-date. And so it’s a pretty intensive process and a lifelong learning process. In contrast, the nutritionist could be anybody. Lisa, you could decide today, you’re a nutritionist. Technically, in many states, you could hang up a shingle and say, come see me, I’m a nutritionist. And so it gets a little confusing, because people assume that people who say they’re a nutritionist know nutrition.
And, unfortunately, over the years, it has been very difficult to convince people or even educate them on what a registered dietitian is. So about a decade ago, the Academy of Nutrition and Dietetics, which is the professional organization that registered dietitians belong to, decided maybe we should opt to call ourselves registered dietitian nutritionists RDN, because then people would start to put it together that there are different kinds of nutritionists. And so many dietitians have moved to the title of RDN, others who’ve been in the field longer may have chosen to stick with the RD only. And so really look for an RDA or an RD when you’re looking for professional help, because you know you have a highly qualified individual.
When I became an oncology dietitian, my whole day was about taking care of cancer patients. I wasn’t seeing one cancer patient and five heart patients and two pediatric patients. I was seeing oncology patients, inpatient, outpatient, all different cancers at all levels of care. And so I really understood the disease process and how it affected the nutritional status of my patients. And so it’s just a matter of an oncology dietitian is really going to have that certification above and beyond the RDN that says, I know my stuff, and I’ll share it with you. And they also have to go through an exam, a special exam to be an oncology dietitian, and they have to repeat that exam every five years, so very intense. You get what you pay for, and the dietitians who put them through, themselves through all that training do so because they know that’s what’s best to meet the needs of their patients.
