Is cottage cheese healthy?

Cottage cheese is having a revival. People are whipping it into dips, baking it into flatbread and spreading it on toast, and plenty of shoppers who wrote it off years ago are putting it back in the cart. If a tub is now in your fridge most weeks, it's fair to ask whether all that eating is doing you any good.

The protein story is the part everyone already knows, and our guide to cottage cheese for weight loss covers it in full. This page is about the rest of the label: the vitamins and minerals in a tub, what its sodium means for your blood pressure, what the heart and diabetes research shows, how much lactose it holds, whether it's safe in pregnancy, how ricotta compares, and who should eat less of it.

If you're trying to eat better, you've probably noticed that every food has fans calling it a superfood and critics calling it a problem. That noise makes it harder to settle into simple habits you can repeat. For cottage cheese the evidence is mostly good news, with one number on the label worth checking every time you buy it.

Cottage Cheese Nutrition per Half Cup

Here's what a half-cup serving (4 ounces, or 113 grams) of the common types gives you, using the averages in USDA FoodData Central. The percentages are shares of the FDA's adult Daily Values.

Values from USDA FoodData Central SR Legacy entries (FDC IDs 173417, 172182, 172179 and 168114), scaled to 113 grams and rounded. Daily Values: phosphorus 1,250 mg, selenium 55 µg, vitamin B12 2.4 µg, riboflavin 1.3 mg, sodium 2,300 mg. Brands vary, most of all in sodium.

Three things stand out. Vitamin B12 is the headline nutrient, with half a cup of 1% covering close to a third of the day's need. Phosphorus and selenium arrive in useful amounts at every fat level. And the sodium column is where brands part ways: regular 1% runs close to 460 milligrams per half cup, while the no-salt-added version stays near 15.

Does Cottage Cheese Contain Phosphorus?

Yes. Half a cup of cottage cheese has about 150 to 180 milligrams of phosphorus, 12 to 14 percent of the Daily Value. Your body uses phosphorus to build bones and teeth and to make ATP, the molecule that carries energy inside your cells.

What's unusual about cottage cheese is how much protein comes with that phosphorus. Low-fat 1% carries about 11 milligrams of phosphorus per gram of protein in USDA's data, against about 27 in plain low-fat yogurt and about 20 in whole-milk ricotta. That ratio matters to people with chronic kidney disease, who often need to limit phosphorus without falling short on protein. A review of dietary phosphorus by Kalantar-Zadeh and colleagues (2010) advised choosing foods with low phosphorus-to-protein ratios and as little added phosphate as possible, because the inorganic phosphate in food additives is absorbed more readily than the phosphorus that occurs naturally in food.

If your kidneys are healthy, there's nothing to avoid here. The phosphorus in cottage cheese is simply part of what makes it a nourishing food.

Vitamin B12, Selenium and Iodine in Cottage Cheese

Vitamin B12 keeps your nerves and red blood cells healthy, and it comes almost entirely from animal foods. Half a cup of 1% cottage cheese gives about 0.7 micrograms, close to 30 percent of the 2.4-microgram Daily Value. That makes a tub a handy source if you eat little meat.

Selenium, a mineral your body builds into antioxidant enzymes, lands at about 10 to 13 micrograms per half cup, roughly a fifth of the 55-microgram Daily Value. Riboflavin, a B vitamin you need to turn food into energy, comes in at 14 to 22 percent depending on the type.

Iodine is the nutrient most labels leave out. USDA's newer laboratory analysis of full-fat cottage cheese measured 45.7 micrograms of iodine per 100 grams. That's about 52 micrograms in half a cup, or a third of the 150-microgram Daily Value. The NIH Office of Dietary Supplements lists milk, yogurt and cheese among good sources of iodine. It's one lab average, so your tub may hold more or less.

Cottage Cheese Sodium and Blood Pressure

Sodium is the one number worth checking on every tub. A half cup of regular cottage cheese carries about 350 to 460 milligrams, 15 to 20 percent of the 2,300-milligram daily limit. Lactose-reduced 1% averages about 250 milligrams in USDA's data, and no-salt-added 1% about 15. Per 100 grams, regular cottage cheese has several times the sodium of plain yogurt, about the same as cream cheese and less than cheddar.

Most of us start the day over budget. The average American eats about 3,400 milligrams of sodium a day, according to the FDA, and a CDC analysis of US eating data (2012) listed cheese among the 10 food categories that together supplied 44 percent of the sodium Americans eat.

Cutting sodium lowers blood pressure, and the trials are clear about how much. A 2013 Cochrane meta-analysis by He, Li and MacGregor pooled 34 trials with 3,230 people who cut their salt for at least four weeks. Eating about 1,700 milligrams less sodium a day, or 4.4 grams of salt, lowered blood pressure by an average of 5.4/2.8 mm Hg in people with high blood pressure and 2.4/1.0 mm Hg in people without it. Bigger cuts brought bigger drops.

Here's what that means for a cottage cheese habit. A daily cup of regular 1% carries about 920 milligrams of sodium, and a cup of the no-salt-added kind carries about 30. Switching saves close to 900 milligrams a day, about half the cut those trials tested, and you keep the food.

Low-fat dairy may even help your blood pressure. In the DASH trial (Appel and colleagues, 1997), 459 adults ate one of three diets for eight weeks while their sodium was held constant. A diet rich in fruits and vegetables lowered systolic pressure by 2.8 mm Hg compared with a control diet typical of what Americans ate. The same kind of diet with low-fat dairy and less saturated fat lowered it by 5.5 mm Hg, and by 11.4 mm Hg in people who already had high blood pressure.

Cohort studies point the same way. A pooled analysis of nine cohorts by Soedamah-Muthu and colleagues (2012), covering 57,256 people, found that every 200 grams a day of low-fat dairy went with a 4 percent lower risk of developing high blood pressure, while cheese showed no link either way. Cottage cheese sits between the two: low in fat like milk, salted like cheese.

If your blood pressure runs high, the no-salt-added tub is the easy win, and so is movement. Our review of isometric exercise and blood pressure covers the wall-squat and handgrip routines that lowered it in trials.

Ricotta vs Cottage Cheese: Which Is Healthier?

For most goals, cottage cheese is the healthier everyday pick, because it has more protein per calorie and far less saturated fat. Ricotta wins on calcium and sodium. Here's how they compare per 100 grams in USDA FoodData Central:

Values from USDA FoodData Central SR Legacy entries 173417, 172179, 171248 and 170851, rounded.

So is ricotta cheese healthy? Yes, in normal portions. It has roughly three times the calcium of cottage cheese and about a quarter to a third of the sodium. The trade-off is fat. Whole-milk ricotta has about ten times the saturated fat of 1% cottage cheese and twice the calories, with less protein. Part-skim ricotta closes the protein gap but still carries several times the saturated fat.

Ricotta and cottage cheese aren't the same cheese, either. Under the federal standard (21 CFR 133.128), cottage cheese is drained curd, called dry curd, mixed with a creamy dressing, and the full-fat version must carry at least 4 percent milkfat. Ricotta is a heat-and-acid cheese. According to the Canadian Dairy Commission, milk is acidified and heated to about 80 to 85°C, and the fine curds that form hold both casein and whey proteins, while a conventional cheese curd is almost all casein. That's why ricotta is smooth and cottage cheese is lumpy.

You can swap one for the other in most recipes. Blended smooth, cottage cheese stands in for ricotta in lasagna or stuffed shells and saves calories and saturated fat, though it adds salt unless the tub is no-salt-added. Going the other way, ricotta gives creamier pancakes and dips, with more calcium and less sodium.

Is Cottage Cheese Healthy for Cholesterol and Your Heart?

For cholesterol, low-fat cottage cheese is one of the gentler dairy choices. Half a cup of 1% has about 0.7 grams of saturated fat and 4 milligrams of cholesterol. Full-fat has about 1.9 grams of saturated fat, a tenth of the 20-gram Daily Value, and 19 milligrams of cholesterol. Per 100 grams, 1% cottage cheese carries 0.6 grams of saturated fat against 19 in cheddar. If your LDL cholesterol is high, saturated fat is the number to watch, so the fat level you buy matters more than the cheese itself.

On heart disease, cheese has a better record than its reputation. A 2017 meta-analysis by Chen and colleagues pooled 15 prospective studies. People who ate the most cheese had a 10 percent lower risk of cardiovascular disease, a 14 percent lower risk of coronary heart disease and a 10 percent lower risk of stroke than people who ate the least, with the lowest risk at about 40 grams a day. Three of its seven authors worked for a dairy company, and the journal later corrected the paper's funding and conflict-of-interest statements. The studies also grouped all cheeses together, so they can't speak to cottage cheese on its own.

Observational studies like these can't prove that cheese protects the heart. What they do show is that a moderate cheese habit didn't carry the extra risk people once expected, and cottage cheese is among the leanest cheeses you can buy.

Is Cottage Cheese a Good Snack for People With Diabetes?

Yes, for most people with diabetes it's a good snack. Half a cup of 1% cottage cheese has about 3 grams of carbohydrate, so on its own it does little to blood sugar. That's been measured, too. In a 1992 metabolic study by Gannon and colleagues in men with untreated type 2 diabetes, 25 grams of protein from cottage cheese produced only a very small rise in blood glucose compared with a glucose drink.

The same study gave cottage cheese together with 50 grams of glucose. The protein trimmed the glucose response by 11 percent, while the insulin response more than doubled. It's a modest effect, but it's in the right direction, and it's why pairing fruit or toast with a protein food makes sense.

Two cautions apply. Diabetes raises the risk of heart disease, so the sodium in a regular tub counts for more, and a no-salt-added version solves that. And the habits that move blood sugar most are the meals and movement you repeat, more than any single snack. Our guide to exercise and type 2 diabetes covers how to build the movement side.

How Much Lactose Is in Cottage Cheese?

Cottage cheese has less lactose than a glass of milk but more than aged cheese. In USDA's data, half a cup of 2% cottage cheese has about 4.4 grams of lactose, full-fat about 3 grams and nonfat dry curd about 1.8 grams. For comparison, the NIDDK says many people with lactose intolerance can have 12 grams of lactose, roughly what a cup of milk holds, with mild symptoms or none. It names yogurt and hard cheeses as lower-lactose dairy.

Many people who think they can't handle any lactose can handle more than they expect. In a double-blind trial by Suarez and colleagues (1997), adults whose bodies had stopped making lactase, including 19 who described themselves as markedly lactose intolerant, drank a cup of milk twice a day with meals for a week. Their symptoms were no worse than during a week of lactose-free milk.

So half a cup of cottage cheese, a quarter to a third of that 12 grams, usually sits well, especially with other food. If it doesn't, look for a tub labeled lactose-reduced or lactose-free, or try yogurt, whose live cultures help digest its lactose, as our page on whether Greek yogurt is healthy explains.

Lactose intolerance and milk allergy are different problems. A milk allergy is the immune system reacting to milk protein, and since cottage cheese is mostly milk protein, no version of it is safe for someone with that allergy. In a national survey of 40,443 US adults by Gupta and colleagues (2019), about 1.9 percent had a convincing milk allergy, making it the second most common adult food allergy after shellfish.

Is Cottage Cheese Safe During Pregnancy?

Yes, as long as it's made with pasteurized milk, so check the label. On its Listeria prevention page, the CDC lists cottage cheese, cream cheese, string cheese, feta and mozzarella made with pasteurized milk as safer choices. The UK's NHS puts pasteurized cottage cheese on its safe-to-eat list for pregnancy.

Listeria is why the label matters. Every year in the US, about 1 in 25,000 pregnant women get a Listeria infection, and the CDC reports that 1 in 4 of them lose the pregnancy or the baby shortly after birth. The CDC is stricter about soft, fresh queso fresco-type cheeses: it advises avoiding them unless they're heated to 165°F or until steaming hot, whether they're made with pasteurized or raw milk.

Cottage cheese also helps with a nutrient pregnancy asks more of. The NIH's Office of Dietary Supplements recommends 220 micrograms of iodine a day in pregnancy and 290 while breastfeeding, up from 150, and USDA's lab sample of full-fat cottage cheese held about 52 micrograms per half cup, close to a quarter of the pregnancy target. It's an easy way to add protein when your appetite is small, too.

Keep it simple: buy tubs made with pasteurized milk, keep them in the fridge and don't eat them past the date.

Who Should Limit Cottage Cheese, and Who Doesn't Need To

Most adults have no reason to cut back. A few groups should talk to a doctor or dietitian first:

• People with chronic kidney disease. Cottage cheese's low phosphorus-to-protein ratio helps, but its sodium and protein still count against kidney limits, and protein targets differ once you're on dialysis. A renal dietitian can tell you how much fits, and a no-salt-added tub is usually the better pick.
• People told to restrict salt. Heart failure, hard-to-control high blood pressure and some kidney conditions come with sodium limits tighter than 2,300 milligrams. Regular cottage cheese eats into those fast, while no-salt-added versions barely touch them.
• Anyone with a milk allergy. As the lactose section explains, no version is safe.

Two groups who often hear they should avoid cheese can usually keep cottage cheese:

• People taking MAOI antidepressants. These drugs can interact dangerously with tyramine, which builds up in aged cheeses. Fresh cheeses made from pasteurized milk, cottage cheese included, are less likely to be high in tyramine, according to the Mayo Clinic. Confirm your own list with your prescriber.
• People with gout. Dairy doesn't appear to raise gout risk, and it may lower it. In a 12-year study of 47,150 men by Choi and colleagues (2004), those who ate the most dairy products had a 44 percent lower risk of developing gout than those who ate the least.

Is Cottage Cheese Good for Weight Loss or Gain?

It helps with both, for the same reason: plenty of protein for very few calories. For weight loss, that protein helps you stay full on fewer calories and hold on to muscle, and our cottage cheese weight-loss guide covers the trials, the casein-before-bed question and eight ways to eat it. For gaining weight or muscle, full-fat cottage cheese adds calories along with about 12.5 grams of protein per half cup, and a bowl with fruit and oats makes an easy extra meal. Either way, the result comes from your total calories and the training you pair it with.

What This Means for You

Cottage cheese earns its place in a healthy diet. It's one of the best protein-per-calorie foods in the dairy case, a good source of vitamin B12, selenium and phosphorus, easy on blood sugar and safe in pregnancy when it's pasteurized. The only habit it asks of you is reading the sodium line. Pick a no-salt-added or lower-sodium tub if your blood pressure runs high or you eat it daily, choose the fat level that suits your goals, and add fruit or vegetables to the bowl, since cottage cheese has no fiber.

Food is the easier half. The harder half is training often enough for that protein to turn into strength, and plenty of plans fall apart right there. Katie put it this way: "I've tried everything.
