Dr. Krystle Zuniga, PhD, RD, CSO, LD, is a board-certified specialist in oncology nutrition with over 14 years of experience encompassing research, higher education, and clinical practice. As the owner of Cancer Nutrition HQ, she is dedicated to providing evidence-based nutritional support to cancer survivors, aiming to enhance their health and quality of life.

In today’s episode, we sit down with Dr. Krystle to bust myths and break down what the science actually says about cancer prevention, survivorship, and the power (and limits) of nutrition. From supplement risks to the misunderstood role of sugar, Dr. Krystle explains the nuance often lost in sensational headlines and social media soundbites. We also explore how movement, muscle, sleep, stress, and even connection with others tie into cancer risk and recovery - zooming out from individual nutrients to look at health through a truly holistic lens. Dr. Krystle offers compassionate clarity in a sea of misinformation, arming listeners with tools to support themselves or loved ones without fear-based messaging or false hope.

If you’ve ever wondered about alcohol, processed meats, or whether “sugar feeds cancer,” this conversation is a must-listen.

“If you respect the power of nutrition, you also respect what it can’t do on its own.”

- Dr. Krystle Zuniga, PHD RD CSO

“We can't reduce risk to zero - but the good news is, the basics go a long way - not just for cancer, but for lifelong health.”

- Dr. Krystle Zuniga, PHD RD CSO
