Citrus fruits are celebrated for their health benefits, but did you know they might pose a hidden risk when combined with sun exposure? Recent studies have raised concerns about certain compounds in citrus fruits that could increase the risk of skin cancer. Here's what you need to know to stay safe while enjoying the sunshine.

The Cancer Culprit: Psoralens and Furocoumarins

Citrus fruits, such as oranges, lemons, limes, and grapefruits, contain naturally occurring compounds called psoralens and furocoumarins. These compounds are known as photocarcinogens, meaning they can interact with sun ultraviolet (UV) radiation to cause DNA damage in skin cells. This damage may increase the risk of developing skin cancers, including basal cell carcinoma (BCC)[i] [ii]  [iii], squamous cell carcinoma (SCC),[iv] and melanoma.[v] One population study found one serving per day of an increase in total citr...

Notice: This information is intended for educational purposes only and should not be used as a substitute for professional medical advice, diagnosis, or treatment. Always consult with your healthcare team before considering the integration of ivermectin or any other therapy into your health program to ensure it aligns with your specific medical needs and circumstances.

Ivermectin History

Ivermectin is a medication primarily used to treat parasitic infections. It was initially developed in the 1970s for veterinary use but was later approved for human use in the 1980s. In humans, ivermectin is prescribed for conditions such as strongyloidiasis (intestinal infection caused by threadworms) and onchocerciasis (river blindness). It is also used topically to treat head lice and skin conditions like rosacea.

Quercetin is a plant-derived flavonol found in many fruits, vegetables, and herbs. Known for its potent antioxidant, anti-inflammatory, antihistamine, and anticancer properties, it’s emerging as a key player in integrative oncology and immune modulation.

If you’re navigating cancer—whether newly diagnosed, in treatment, or in recovery—you’ve likely heard about antioxidants and immune support. But one compound stands out: quercetin, a flavonoid found in everyday foods like onions, apples, and broccoli. Emerging research suggests quercetin may help regulate inflammation, stabilize histamine levels, and even influence cancer-related pathways like apoptosis and angiogenesis. In this...

Recent medical studies have shown promising anticancer effects, making it a potential natural treatment for cancer.

Written by Keith Bishop, Clinical Nutritionist, Cancer Coach, Author, and Retired Pharmacist

Boswellia serrata, or frankincense, has been used in traditional medicine for centuries. Recent studies have shown promising anticancer effects, making it a potential natural treatment for cancer.

Health Benefits of Boswellia

Boswellia offers a range of health benefits beyond its anticancer properties. Its potent anti-inflammatory effects make it helpful in treating conditions such as arthritis, inflammatory bowel disease (IBD), and asthma. Additionally, Boswellia can help reduce pain and improve respiratory health.[i]

Boswellia Anticancer  Ingredients and Mechanisms

Boswellia's anticancer properties are primarily attributed to its active compounds, boswellic acids. These compounds inhibit the production of leukotrienes, molecules that contribute to inflammation and t...

Cancer cells can remarkably manipulate their environment to support their growth and spread. One key component of this environment is collagen, a significant protein in the extracellular matrix (ECM). Collagen provides structural support and is crucial in cancer progression and metastasis.

I want to share my concerns since collagen peptide protein powders are popular. 

Collagen peptide proteins, derived from enzymatic hydrolysis of collagen, provide high doses of type I and III collagen. These collagens are particularly significant in cancer progression, as they contribute to the structural integrity and stiffness of the tumor microenvironment. Cancer cells can exploit these collagen-rich environments to enhance their adhesion, migration, and invasion capabilities, promoting tumor growth and metastasis. Studies have shown that cancer cells can utilize collagen peptides to create a protective extrace...

Learn about the anti-cancer benefits of Cannabigerolic acid (CBGa), a non-psychoactive cannabinoid found in the cannabis plant.

Written by Keith Bishop, Clinical Nutritionist, Cancer Coach, and Retired Pharmacist

The world of health and wellness is continually evolving, with new research and discoveries coming to light regularly. One such breakthrough is the potential anti-cancer benefits of Cannabigerolic acid (CBGa), a non-psychoactive cannabinoid found in the cannabis plant. This blog post explores the potential benefits of CBGa, its sources, and possible concerns and side effects, all backed by medical journal references.

Understanding CBGa

CBGa, often called the "mother of all cannabinoids," is the precursor from which other cannabinoids are made in the plant. It's sourced from the cannabis plant, specifically from young, immature plants. CBGa is non-psychoactive, meaning it won't cause the "high" associated with cannabis use. Its previous research has been hampered because t...

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.

Updated December 2024

This paper discusses the Glucose Ketone Index (GKI) a tool developed by Dr. Thomas Seyfried and his team at Boston College, and L-Glutamine restriction as a strategy for managing cancer growth.[1] The GKI It is the ratio of blood glucose to ketone bodies. The higher the ratio the higher the glucose and lower the ketone bodies. The lower the ratio the lower the glucose and higher the ketone bodies.

GKI and Cancer

There is a very strong association between elevated blood glucose, oxidative stress, inflammation and the higher risk of cancer.[2] Ketone bodies (the body using fat for energy) and ketogenic diets appear to be powerful agents in treating human cancers. Ketone bodies often enhance the effectiveness of chemotherapy treatments.[3]

Dr. Seyfried's research in the realm of cancer treatment has shown increasingly impressive therapeutic outcomes with lower GKI r...
