Baby Dietitians


By: Katie Dunn, Dietetic Intern



Being a dietetic intern is so exciting. It’s short time frame in our path to becoming a registered dietitian sandwiched between graduating college and beginning our professional career. In a sense, we are “baby dietitians”.

We are baby professionals in a field which has been referred to as a “baby science”. They call nutrition a “baby science” because we’ve only just begun to see the tip of the iceberg in nutrition research. Nutrition sciences have come a long way, but there's still so much to learn which means I’ve chosen a career path that’s far from dull.

They don’t call nutrition a “baby science” because it’s a field for babies. In fact, that couldn't be farther from the truth. It takes confidence, wit, and compassion to be a dietitian. We are constantly bombarded by the latest fad diets and detox teas promising weight loss solutions backed by pseudo science. We are challenging the status quo in healthcare with innovative preventive measures that are often overlooked. We are proving our value in acute care settings with thorough assessment and effective interventions.

I didn’t truly understand this when I chose to study nutrition and dietetics. I just knew that I loved food and I was fascinated by human metabolism. In fact, like many dietitians will admit, I didn't even really know the full scope of what a dietitian does until this internship.

The problem is that there are many people that just don’t know exactly what dietitians do or how we can help. This includes people who are seeking nutrition advice as well as other healthcare professionals such as physicians, nurses, physical therapists, occupational therapists, pharmacists, etc.

This has become evident to me as I sit with my preceptors in “rounds” (a meeting with all members of a healthcare team meet to discuss the plan of care for patients), and through my Interprofessional Team Seminar (IPTS) meeting with other students in healthcare professions. They know that we can recommend nutrition supplements and talk to patients about food, but that seems to be it.

Our expertise are valuable in today’s world. We are educators, counselors, motivators, researchers, teachers, managers, and so much more. We seek out evidence based research to facilitate healing in acute settings like hospitals, as well as motivate our clients to make lifestyle changes for wellness and longevity. We are changing lives of others, helping them to cultivate better relationships with food and understand why it’s so important.

Ten years from now, I want more people to recognize the full scope of a dietitian’s role, especially healthcare professionals. This means I must advocate for my profession and encourage other dietitians to do the same, and I will proudly do so.

Sports Dietetics


by Megan Cooper

There are many different areas within the dietetics profession. The area that is most interesting to me is sports dietetics. I was involved in dance, tumbling, and cheerleading from the beginning of elementary until the end of high school. It really wasn’t until I was nearing the end of high school that I began to realize just how important nutrition is in regards to physical performance. I think back now to all the times I didn’t eat before practice or before competitions and I wonder how much better I would have felt and how much better I would have performed if I would have been more knowledgeable about nutrition and how it affected my performance. After graduating high school, I knew I had to find some different ways to stay physically active, so I began weight lifting, jogging, and trying various fitness classes. At this point, I was studying nutrition and dietetics and I was becoming even more aware of the benefits of both nutrition and exercise. Some of the health benefits associated with consuming a healthy, balanced diet include weight control and reduced risk for many diseases such as diabetes, cardiovascular disease, and certain types of cancer. Some of the benefits of exercise include weight control, reduced risk of cardiovascular disease, type 2 diabetes, metabolic syndrome, and certain types of cancer, stronger bones and muscles, and improved mental health and mood (Physical Activity and Health, 2018). I believe there are so many benefits that can be gained from exercise and from eating a healthful, balanced diet that I cannot understand why anyone would not want to live a healthy, active lifestyle! Since I believe nutrition and physical activity go hand in hand, it ultimately led me to my goal of wanting to become a sports dietitian.

What exactly is a sports dietitian?

“A sports dietitian provides individual and group/team nutrition counseling and education to enhance the performance of competitive and recreational athletes, on-site and during travel” (Clark & Steinmuller, 2012). Sports dietitians may work in individual nutrition counseling to assess and analyze dietary practices, body composition, and energy balance of athletes, counsel athletes on optimal nutrition for exercise training, competition, recovery from exercise, weight management, hydration, and supplementation, and provide meal and snack plans to help athletes achieve athletic performance goals. Sports dietitians may also work in food service and menu development and coordinate pre and post competition meals and snacks, purchase nutritional supplements, and deliver nutrition education to food service personnel. Sports dietitians may also provide nutrition education for teams, groups, or wellness programs (Clark & Steinmuller, 2012). Some of the skills needed to become a sports dietitian include communication, presentation, and counseling skills, ability to accurately assess height, weight, body composition, and energy balance, knowledge of nutritional supplements, knowledge of rules and regulations of athletic governing bodies regarding banned drugs and restricted substances, and knowledge of measurements of resting metabolic rate, energy expenditure, VO2max, and lactate threshold (Clark & Steinmuller, 2012).

How do you become a sports dietitian?

The first step is completing a bachelor’s degree in nutrition and dietetics. After that, a dietetic internship must be completed and the Commission on Dietetic Registration exam to become credentialed as a Registered Dietitian must be taken and passed. Once you are officially an RD, a minimum of two years of experience, preferably in a sports nutrition setting, is required in order to become a Certified Specialist in Sports Dietetics (CSSD). The NCAA Sport Science Institute (SSI), Sports, Cardiovascular, and Wellness Nutrition (SCAN), and the Collegiate and Professional Sports Dietitians Association (CPSDA) are all organizations that you can become a member of now if you want to get more involved in sports dietetics.

Move with the BEET!


By Alyssa Bossle

What if there was such thing as a drink that could benefit your overall performance, increase blood flow, improve lung function and strengthen muscle contractions?  Well, you might be surprised to know, this drink already exists! Research has shown that beet juice has all these benefits and more for enhancing athletic performance. Diets rich in vegetables like beets are shown to have a significant impact on body functions during exercise as well as aid in recovery after a workout. In fact, beet juice is becoming one of the most popular ergogenic and natural supplements used by athletes.

So, what makes beets such an athletic nutritional superfood?

Beetroots contain high amounts of inorganic nitrates, and after they are consumed, beetroots increase levels of nitric oxide in the body.  This serves multiple functions related to increased blood flow, improved lung function and stronger muscle contractions, as mentioned earlier. Beets also provide a boost stamina, which helps the body last longer during exercise. It's been well researched that a diet rich in vegetables can improve cardiovascular health, due to this high nitrate content. While all vegetables contain some nitrates, they are more abundant in beetroots, leafy greens, spinach, celery, arugula, and parsley.

What does nitric oxide do for your body?
  • ·         Improves oxygen delivery to cells
  • ·         Expands blood vessels  
  • ·         Leads to lower blood pressure
  • ·        Improves overall circulation
  •         Boosts energy
  • ·         Aids in digestion
  • ·         Improves immunity
  • ·         Improves sleep quality

What does the research say on how much you need?

Every person is different, so it is difficult to state one specific number for the entire population. From what has been seen in studies, drinking as little as 4 oz, or half a cup, two to three hours before exercise is sufficient to receive the many benefits beet juice has to offer. In one study, a group of researchers wanted to find out if consuming more beet juice is better or if there is an upper level, so they put it to the test. They set up a group of men on an exercise bike and had them cycle until they exhausted all their energy and could no longer pedal. The subjects made it about eight minutes after drinking a placebo. After one ounce of beet juice, which is about a quarter of a cup, some participants gained a few seconds while others showed no change. However, drinking about 4 ounces, or half-cup, gave them a full extra minute without exhaustion. Drinking even more didn’t seem to offer any additional benefit. The 4 ounces of beet juice corresponds to 8 units of nitrate. So, 4 units didn’t significantly work, and 16 did no better than 8 units found in the 4 ounces. The 8 units, found in the 4 ounces of juice, appears to be the best amount for improving athletic performance (Wylie, L.J., 2013)

 *PL – Placebo
*BR – Beetroot Juice

What other benefits does beet juice provide?

Consumption of beet juice is known to have anti-inflammatory properties and antioxidant properties, which helps to reduce the oxidation of LDL, or the “bad” cholesterol, protect the artery walls and guard against heart disease and stroke, according to the American Journal of Clinical Nutrition. Beets are good sources of folate, potassium, vitamin C, and fiber. It also aids in the absorption of iron, which ensures that our muscles are working properly by delivering oxygen to our tissues.

Tips for beet juice consumption

·        * It is suggested to avoid drinking beet juice on an empty stomach. 
o   Beet juice is very acidic, and when taken on an empty stomach, it can make you feel more nauseated than energized.
·         *Try mixing with lemon juice and ginger to give it more flavor.
·        * If your drink is too thick you can add some water to balance the consistency.
·         *Mix in with other fruits or vegetables to make a smoothie. (See recipe below)
·         *Don’t remove the pulp! That’s where all the fiber is.

Try it out!

Last Comments

Although researchers have narrowed down a recommended amount of beet juice to be consumed in order to enhance performance and have significant benefits on health, further research is needed to determine long-term effects and outcomes on performance. 

If you are an athlete and are interested in consuming beet juice to enhance performance, it is important to check with your sports nutritionist, athletic trainer, or coach before consuming.
