How pumpkin seeds support anticancer nutrition, key nutrients, research findings, and practical guidance. 

Research and written by Keith Bishop, Cancer Coach, Clinical Nutritionist, Retired Pharmacist, and Founder of Prevail Over Cancer™ and the Prevail Protocol™

Pumpkin seeds—often treated as a simple snack—are quietly becoming one of the most compelling foods in anticancer nutrition. Rich in bioactive compounds, antioxidants, lignans, and unique proteins, these seeds have demonstrated promising effects in laboratory studies and population research. Below is a comprehensive, evidence-based look at what we know so far.

Anticancer Actions of Pumpkin Seeds

Pumpkin Seed Apoptosis-Inducing Activity

Pumpkin seed protein fractions have been shown to induce apoptosis (programmed cell death) in cancer cells, including liver (HepG2) and triple-negative breast cancer (MDA-MB-231) cell lines.[i]

Antioxidant & Anti-Inflammatory Effects

Pumpkin seeds contain phenolic compounds, tocopherol...

The Anticancer Actions of IV Vitamin C: Mechanisms, Dosing, Safety Labs, and Integration with Oncology Care

Researched and written by Keith Bishop, Clinical Nutritionist, Cancer Coach, and Founder of Prevail Over Cancer™, and the Prevail Protocol™

High-dose intravenous vitamin C (IVC) has reemerged as a promising adjunctive therapy in integrative oncology. Modern research highlights its unique pharmacology, potential anticancer mechanisms, and its ability to support patients undergoing chemotherapy, radiation, and immunotherapy. This guide breaks down the science, dosing considerations, safety labs, and clinical integration—supported by peer-reviewed medical literature.

What Makes IV Vitamin C Different From Oral Vitamin C?

Oral vitamin C absorption is tightly limited by intestinal transporters, which cap blood levels even at high doses. In contrast, IV administration bypasses intestinal absorption and produces blood concentrations 100–500× higher than those required for a...

Foods, supplements, and lifestyle habits that support your immune system’s interferon natural defense.

What Is Interferon?

Interferons are natural proteins your body makes to help fight infections and abnormal cells—including cancer. They act like messengers, telling your immune system to wake up, attack, and clean up. There are three main types:

• Type I (IFN-α and IFN-β): These help stop cancer cells from growing and spreading.
• Type II (IFN-γ): This type activates immune cells to recognize and destroy cancer cells.
• Type III (IFN-λ): Mostly helps protect surfaces like your skin and gut, with growing interest in cancer research.

Interferons are so powerful that some cancer treatments use them directly or try to boost their effects.[i]

Cancer Cells Thrive on Glucose and L-Glutamine: Insights from Dr. Thomas Seyfried

Dr. Thomas Seyfried, PhD, has extensively researched how cancer cells depend on glucose and L-glutamine for their growth and proliferation. Cancer cells exhibit altered metabolism, relying heavily on glucose (the Warburg effect) and L-glutamine (an amino acid) to fuel their rapid division and growth. By disrupting these metabolic pathways, we can effectively starve cancer cells and inhibit their growth.

Unveiling the Power of Green Tea, Matcha and EGCG: A Natural Ally in Cancer Prevention and Treatment

Written by Keith Bishop, Clinical Nutritionist, Cancer Coach, Retired Pharmacist, and Founder of Prevail Over Cancer. 

In my ongoing quest to empower our community with knowledge and tools to prevail over cancer, I turn my focus to one of nature's most potent gifts: green tea. Revered for centuries for its healing properties, green tea has emerged as a beacon of hope in cancer prevention. Join me as I delve into the science behind green tea's anticancer benefits and explore how integrating this miraculous beverage into our daily routine can fortify our defenses against this formidable adversary.

Green Tea: The Cancer Antioxidant Powerhouse

At the heart of green tea's anticancer prowess lies its rich concentration of antioxidants, particularly catechins. Epigallocatechin-3-gallate (EGCG), the most abundant and powerful catechin in green tea, has been extensively studied for its abili...
