Lack of oxygen: The “Warburg Effect,” described by Dr. Otto Warburg (1931), demonstrates that cancer cells primarily rely on glucose fermentation instead of aerobic respiration. A 2019 report in Science Translational Medicine also highlighted that a low-oxygen environment promotes cancer invasion (Semenza, 2019).Acidic environment: Lactic acid buildup from glucose fermentation creates a favorable environment for tumors. A 2021 study in Cancer Research found that tumor acidity suppresses the immune system (Fischer et al., 2021).Olive Leaf Extract: A Powerful Natural Cancer RemedyOne natural remedy advocated by Barbara O’Neill is olive leaf extract. Olive leaves contain oleuropein, a compound with strong antioxidant, antibacterial, and anti-inflammatory properties.A 2022 study in the International Journal of Molecular Sciences demonstrated that oleuropein can slow the growth of breast and prostate cancer cells by inhibiting the PI3K/Akt/mTOR pathway (González-Vallinas et al., 2022). Additionally, a 2018 Oncotarget study reported that oleuropein induces apoptosis (programmed cell death) in colorectal cancer cells (D’Angelo et al., 2018).Diet as a Cancer-Fighting ToolBarbara O’Neill emphasizes the importance of diet in cancer prevention. Here are some science-backed beneficial foods:
