Alkaline Diet / Acid-Ash Cancer Theory
Alkaline Diet / Acid-Ash Cancer Theory is a cancer-related diet or nutrition protocol discussed for nutrition status, metabolic support, inflammation, digestion, immune resilience, treatment tolerance, or alternative cancer-treatment claims. In cancer care, it should be evaluated by evidence level, intended use, safety, interactions, and whether it is being used as conventional treatment, supportive care, an experimental adjunct, or an alternative claim.
