This is where the internet gets weird. You’ll see “alkaline diet” gurus screaming that milk is “acid-forming” and will leach calcium from your bones. Spoiler: that’s mostly nonsense. Your body is a master at regulating its own pH (around 7.4 in your blood). Drinking a glass of milk—even slightly acidic—won’t throw off that balance.

In fact, milk is slightly acidic itself, but it has a buffering capacity. That means it can neutralize some acids in your stomach. That’s why a glass of milk can calm heartburn for some people (though for others, it backfires—bodies are weird, don’t let them gaslight you).
So, if you’re worried about “alkalizing” your body? Save your money. Just drink the milk—or oat milk, or whatever makes your taste buds happy. Your pH police (your kidneys and lungs) have it under control.
The Real Takeaway: pH is Just a Number
Look, the next time you’re pouring milk into your coffee and wondering if you’re committing a chemical crime—you’re not. A pH of 6.7 is basically a shrug from the universe. It’s fresh, it’s fine, and it’s not going to melt your mug.
But now you know: milk is a slightly acidic, surprisingly versatile liquid that just wants to be understood. And if your oat milk curdles in hot coffee? Check the pH on the carton. Or just blame the brand. That’s always acceptable.
So go forth, ask your barista for the pH of their almond milk, and watch them blink. You’re welcome. And remember—milk’s pH isn’t a mystery. It’s just a number that keeps your coffee from turning into cheese.
