    Hello, I’m confused about using oil. I understand the Nutrivention diet does not use oil? I’m trying to find recipes that I can use to lower my risk of cancer (still in the testing phase). There doesn’t seem to be a Nutrivention cookbook, or recipe booklet that I know of. I’m not sure if I can use oil, or not use oil in cooking, or just as a salad dressing. Can you clarify? Many thanks. Best, Connie

      Hi Connie,

      Thank you for your comment — great question. This is definitely an area with differing opinions in the plant-based nutrition space. I love Dr. Shah’s work, and I think these conversations are important and needed.

      Nutrivention emphasizes a predominantly whole-food, plant-based pattern, with most fats coming from whole food sources like nuts, seeds, avocado, olives, and soy foods — which I’m a big advocate for.

      That said, and as you mentioned, research consistently supports dietary patterns rich in whole plant foods — vegetables, fruits, legumes, whole grains, nuts, and seeds — for cancer prevention and survivorship. Ultimately, the overall dietary pattern matters most.

      When it comes to oils, while I strongly believe healthy fats can absolutely come from whole food sources alone, I’m not personally opposed to small amounts of high-quality oils used intentionally. If using oils, I recommend prioritizing options like extra virgin olive oil or avocado oil over heavily refined oils, while also minimizing saturated fats where possible.

      Personally, I think small amounts of oil can make plant-based eating more practical, sustainable, and enjoyable for some people — and that context matters, too.

      So no, I don’t believe someone needs to fear a drizzle of EVOO on a salad or small amounts used in cooking. If someone prefers to be fully oil-free, that is certainly an option as well and one that I support. As an oncology dietitian and cancer survivor myself, I focus less on perfection and more on building meals around minimally processed plant foods consistently over time.

      Hope that helps clarify things a bit! The research around this nuance simply isn’t fully black-and-white. 💛
