Hi, I’m Krystle Zuniga

PhD, RD, CSO, LD

I’m a Registered Dietitian and Board-Certified Specialist in Oncology Nutrition, and I’ve spent over 18 years working in nutrition and cancer as a researcher, educator, and clinician.

A Little About Me

After my B.S. in Dietetics my curiosity about the why behind nutrition and disease led me to pursue a PhD in Nutritional Sciences, where I studied the role of diet in cancer. I began my career in academia, continuing to study nutrition and cancer while teaching in higher education

But over time, something felt like it was missing. The research was meaningful, but the impact felt distant. I was discouraged to see the long gap between what we were learning in research and what was actually being implemented in clinical practice.

So I made a shift into full-time clinical practice, working directly with patients navigating cancer treatment and recovery. That’s where everything changed.

I was sitting across from patients who were overwhelmed, scared, and confused by conflicting nutrition information they had read online, heard from others, or seen on social media. I was shocked to discover how much of that information didn’t align with the evidence.

It raised several questions for me:
Why isn’t the science reaching people in a way that’s clear and usable?
Why are patients left to sort through this on their own?
Why aren’t more scientists and clinicians part of these conversations?

So I started showing up.

What began as a way to share evidence-based information has grown into Cancer Nutrition HQ—a platform focused on making oncology nutrition easier to understand and more practical to apply.

Today, my work brings together my background in research, clinical care, and education. I teach, speak, work with patients, and create content through social media and my podcast, to help bridge the gap between evidence and application.

Because when information is clear and accessible, it has the power to reduce fear, support better decisions, and help people feel more empowered in how they care for their bodies.

Cancer Nutrition HQ exists because everyone affected by cancer deserves access to nutrition guidance they can trust. I built this to be that place, and I’m grateful to share it with you.
