About us

DSC was created for you, dietitian.

We believe that in order to make positive, lasting change in the field of dietetics, we need to support our profession to build and develop their expertise. The nutrition field is constantly changing and evolving, you shouldn’t have to manage that alone. That’s why we offer an affordable membership to provide widespread access to our materials to dietitians, dietetic students and nutritionists around the globe.

DSC is committed to providing you with high quality, evidence-based content. We have spent the last two years striving to develop a gold standard process for content development and review. Our goal is to create a process that allows us to 1. Keep up with the ever-changing needs of nutrition practitioners, 2. Create content that reflects relevant nutrition issues in a timely manner and 3. Create content that can be easily updated as new research and evidence is released.

Here is our current content development process:

Needs are identified

We make is easy for our members to request content. We prioritize our content development based on what our members tell us they need. We release new content monthly.

Content development

Once a topic is identified, our Registered Dietitian Content Manager starts to develop  handouts, course content, resources & evidence reviews using the most up-to-date, high quality evidence-based nutrition information and current best practice recommendations.

Practice-based review

Once content is developed,
we work with a Registered Dietitian with at least 5 years of practice-based experience in that area to review the content, review references and add practice based case studies.

Technical review

Once practice review is complete, our Technical Review process begins whereby we do a final edit and assessment to make sure numerical values, spelling, grammar and references are all correct.

At DSC, we operate by four core values:


We do things differently. We believe that the evolution of dietetics is in our hands and it is up to us to create the future we want. We are unafraid to take the lead and pave the way.


We have a zero tolerance policy for disrespect in our community. We hold our content creators and community to a high standard. Employing dietitians and reinvesting back into the profession is a top priority for us.

Evidence-Based Nutrition

We are a gathering space for ALL dietitians and dietetic students, regardless of your practice area or expertise. We aim to present evidence-based nutrition content that is free from bias, based on what the current literature is telling us. 


We welcome feedback and incorporate member comments into our resource development. We also take resource requests from our members, to ensure you are getting the support you need.

The DSC Team

DSC currently includes 3 core team members. We also work with countless dietitians on a contract basis. Reinvesting back into the dietetics profession and employing dietitians is a priority for us.
