- Third-party site: the Tayebat system can serve as a preventive lifestyle against cancer (less processed meat, refined sugar, fried food, soft drinks), not as treatment; cancer patients must follow their oncology team and keep screening. – Studies supporting the claim
- Cross-system summary: avoiding the system's forbidden foods (industrial eggs, chicken, dairy, white flour, UPF, soft drinks, leafy greens, legumes, acid blockers, supplements) prevents cancer. – Studies with mixed or unclear results
