Does feta have lactose? Yes, but not as much as you might think. A one-ounce serving—about 1/4 cup crumbled—typically contains around 1 gram of lactose. That’s far less than the roughly 12 grams in a cup of milk, which is why feta can still fit into many lactose-intolerant meal plans.
Why feta is lower in lactose than milk
Lactose is the natural sugar found in milk. When feta is made, cheesemakers drain off much of the whey, then live cultures keep converting leftover lactose into lactic acid. Because feta is stored in salty brine, moisture—and some lactose—also moves out of the cheese.
Still, feta doesn’t receive the long aging that cheeses like Parmesan do, so it keeps a small amount. Fresh, creamier feta will generally have a little more lactose than a drier, more thoroughly drained one. The animal source doesn’t change much: sheep’s milk and goat’s milk contain lactose too.
How much lactose is actually in feta?
Most commercial feta lands at about 1 gram of lactose per ounce. Here’s how that compares with other dairy:
- Whole milk (1 cup): about 12 grams of lactose.
- Feta (1 ounce): about 1 gram of lactose.
- Aged cheddar or Parmesan (1 ounce): usually less than 0.5 gram.
Your personal limit matters more than those numbers. Many people with lactose intolerance handle up to 12 grams of lactose if it’s spread across the day and eaten with meals; others can feel symptoms from 1 gram. If you do well with Greek yogurt or a sprinkle of Parmesan, feta is probably worth trying. If you know even small amounts bother you, choose an aged hard cheese or a lactose-free feta-style product instead.
💡 Note: Want to test feta comfortably? Start with 1 tablespoon crumbled over a full meal, not on an empty stomach. That keeps the dose tiny while you learn how your body responds.
Keep feta in its proper place: a tangy finishing cheese. Crumble it over salads, grain bowls, soups, or roasted vegetables, where a little goes a long way. For most people with lactose sensitivity, that small, flavorful amount is enough to enjoy it—without spending the rest of the day wondering why you tried it.
