We hear so much about alkaline diets and alkaline water, but the colonic ecosystem (microbiome) is different.
When beneficial bacteria ferment dietary fibre, they produce short-chain fatty acids like butyrate, which help lower colonic pH.
Your colon is also meant to be an extremely 𝐥𝐨𝐰-𝐨𝐱𝐲𝐠𝐞𝐧 environment.
Health promoting bacteria like Faecalibacterium and Roseburia are obligate anaerobes & they need oxygen-free conditions to thrive.
But when the gut lining becomes dysfunctional, more oxygen can leak into the colon, giving oxygen-tolerant opportunistic bacteria a competitive advantage. Enter dysbiosis 🫨
BUTYRATE plays a crucial role here. Your colon cells use it for fuel, consuming oxygen in the process and helping maintain that low-oxygen environment.
So more prebiotic fibre > more short chain fatty acids > colonic PH goes down. You get me? This allows friendly microbes to thrive, and oxygen loving / alkaline microbes to starve.
𝐃𝐘𝐒𝐁𝐈𝐎𝐒𝐈𝐒 treatment plans do not need to involve prolonged anti-microbials. Change the PH - Change the dysbiosis! You’re welcome 🤓
