Which practical eating strategy best leverages fermented foods to support digestive health without over-relying on a single probiotic strain?

• A. Rotate several fermented foods (e.g., yogurt, kimchi, kefir, sauerkraut) across the week while maintaining varied fiber sources to support multiple strains and their substrates.
• B. Replace all plant foods with fermented animal products exclusively, because animals’ fermented products contain proprietary bacterial strains that act identically to a broad, diverse microbiome.
• C. Only eat fermented foods intermittently once a month because frequent exposure will cause permanent displacement of native microbes and harm digestive health.
• D. Consume a single brand of high-CFU probiotic yogurt multiple times daily and avoid any other fermented foods or fiber sources to ensure dominance of that strain.
