Greek Yogurt vs. Cottage Cheese: Protein Is Close, Sodium Isn't
Greek yogurt and cottage cheese are the two reigning high-protein darlings of social media — one silky-smooth, the other salty and curdy. Which is actually better for you? Drawing on dietitian analyses compiled by Verywell Health, Peloton's health column, Diet Doctor and Jackson Health System: cottage cheese edges ahead on protein, but the sodium gap is enormous — roughly ten to one. The right pick depends on your health goals.
Per one cup (about 226 g), cottage cheese delivers roughly 24–25 grams of protein versus 20–24 grams for low-fat Greek yogurt. Diet Doctor notes that standard serving sizes can mislead — a typical Greek yogurt serving is 5 ounces while cottage cheese is sold in 4-ounce servings; eat a full cup and cottage cheese lands at 24–28 grams, matching or beating the yogurt. Dietitian Bouchard's verdict: the difference is small, but if you struggle to hit your protein target, those extra grams genuinely matter.
This is where the two diverge hardest. Salt is added during cottage cheese production, pushing a cup to roughly 700–800 mg of sodium — nearly a third of the daily recommended limit. Greek yogurt has only about 70–83 mg per cup. The American Heart Association suggests an ideal sodium ceiling of 1,500 mg a day, so anyone watching blood pressure should default to the yogurt. Low-sodium cottage cheese exists — read the label.
Greek yogurt carries more calcium (about 282 mg per cup versus 187 mg for cottage cheese), and as a fermented food it naturally contains probiotics that support gut bacterial balance. It's also lower in lactose, making it the friendlier option for the mildly lactose-intolerant. Cottage cheese probiotics depend on the brand — Good Culture and Muuna add live cultures, so look for "live active cultures" on the package.
Plain versions of both are naturally low in carbs (around 5–9 grams per serving), but flavored tubs are the trap: fruit-on-the-bottom and sweetened nonfat yogurts can hit 32 grams of carbs per serving, and pineapple cottage cheese reaches 15 grams. Dietitians are unanimous: buy plain, then add your own berries, cinnamon or vanilla. Cottage cheese also shines savory — black pepper, herbs or everything-bagel seasoning.
Cottage cheese for a few extra protein grams and a savory bite; Greek yogurt for lower sodium, probiotics and a gentler gut. Gisela Alvarez, a dietitian at Jackson Memorial Medical Center, offers two kitchen hacks: blend cottage cheese into pasta sauce for a protein boost, or swap sour cream for Greek yogurt with a pinch of salt on tacos.
