In simple terms, alkaline is the opposite of acidic. Your body runs on a pH scale from 0 (super acidic) to 14 (super alkaline), with 7 being neutral. Blood, for example, likes to hang out at a tight 7.35 to 7.45. That’s slightly alkaline, and your body fights like a tiny, invisible bodyguard to keep it there. No, drinking alkaline water won’t magically change your blood pH—your lungs and kidneys are the real gatekeepers here.
But that doesn’t stop the internet from screaming that alkaline foods “detox” you. The truth? Your stomach’s pH is around 1.5 to 3.5—basically battery acid level. Anything you eat or drink gets hit with that acid instantly. So that $3 bottle of alkaline water? It’s neutralized before it even leaves your stomach. (Sorry to burst your bubble, or rather, your alkaline bubble.)
