Swiss cheese, fresh mozzarella, ricotta, and cottage cheese are among the best options if you have high blood pressure, primarily because they’re lower in sodium than most other cheeses. But the type of cheese matters less than the version you buy: reduced-fat, low-sodium varieties of almost any cheese can fit into a blood-pressure-friendly diet. The key is knowing what to look for on the label and how much to eat.
Why Cheese and Blood Pressure Clash
The main issue with cheese isn’t the dairy itself. It’s the sodium. Most cheese relies on salt for flavor and preservation, and sodium directly raises blood pressure by pulling more water into your bloodstream and increasing the volume your heart has to pump. The American Heart Association recommends staying under 2,300 milligrams of sodium per day, with an ideal limit of 1,500 milligrams for people who already have high blood pressure. A single ounce of regular feta or blue cheese can pack 300 to 400 milligrams, eating into that budget fast.
Saturated fat is the secondary concern. Diets high in saturated fat contribute to arterial stiffness over time, which makes blood pressure harder to control. Full-fat hard cheeses tend to be the worst offenders on both counts.
The Lowest-Sodium Cheeses
Swiss cheese stands out as the clear winner for sodium. A typical 21-gram portion contains just about 39 milligrams of sodium, a fraction of what you’d get from cheddar or parmesan. Fresh mozzarella comes in around 147 milligrams for the same portion, which is still moderate. Ricotta checks in at roughly 102 milligrams per 100-gram serving, making it another reasonable choice, especially the part-skim version.
Cottage cheese deserves special mention. Standard cottage cheese is surprisingly salty, often 300 milligrams or more per half cup. But “no salt added” versions drop to around 60 milligrams per serving, which changes the picture entirely. Low-fat, no-salt-added cottage cheese is high in protein and calcium with very little saturated fat, making it one of the most heart-friendly cheeses you can buy.
What the DASH Diet Recommends
The DASH diet is the most well-studied eating plan for lowering blood pressure, and it doesn’t cut out cheese. It includes 2 to 3 daily servings of low-fat dairy, with one serving of cheese defined as 1.5 ounces. That means you can eat roughly 3 to 4.5 ounces of cheese per day within the plan’s framework, as long as you choose wisely.
The DASH meal plans published by the National Heart, Lung, and Blood Institute specifically call for reduced-fat, low-sodium natural cheddar cheese in multiple meals throughout the week. They also suggest swapping in reduced-fat Swiss cheese as an alternative. For recipes like lasagna, the guidance is to use low-fat, no-salt-added cottage cheese. The consistent theme: pick reduced-fat versions first, then look for low-sodium options within that category.
Cheeses With Blood-Pressure-Lowering Compounds
Some cheeses contain natural compounds that may actively lower blood pressure rather than just being less harmful. During aging and fermentation, milk proteins break down into small peptides that can block an enzyme your body uses to tighten blood vessels. This is the same mechanism targeted by a common class of blood pressure medications.
These peptides have been identified in several aged and fermented cheeses, including cheddar, manchego, and asiago. A meta-analysis found that food-derived versions of these peptides could lower systolic blood pressure by about 5 points. One Norwegian cheese called Gamalost, made from skimmed milk with no added salt and less than 1% fat, showed particularly strong activity. In a clinical trial, people with borderline-high blood pressure who ate Gamalost saw reductions of roughly 4 points systolic and 3.5 points diastolic over four weeks compared to a control group, though the results didn’t quite reach statistical significance.
Fermented cheeses containing live probiotic cultures add another potential benefit. A pilot study in adults with obesity and high blood pressure found that cheese made with a specific strain of Lactobacillus plantarum was associated with lower morning diastolic blood pressure. The more the probiotic colonized participants’ guts, the greater the blood pressure change. Fermented milk products with Lactobacillus helveticus have shown similar results in hypertensive adults when consumed daily.
Minerals That Work in Your Favor
Cheese isn’t just a sodium delivery vehicle. Dairy products supply three minerals that are inversely associated with blood pressure: calcium, potassium, and magnesium. A cup of milk provides about 300 milligrams of calcium (30% of your daily value) and 350 milligrams of potassium. Cheese concentrates the calcium further. Research has consistently found that higher dietary calcium intake correlates with lower odds of developing hypertension, and potassium directly counteracts sodium’s effects by helping your kidneys excrete more of it.
This is why eliminating dairy entirely isn’t the best strategy if your goal is blood pressure management. The DASH diet’s emphasis on low-fat dairy exists precisely because the mineral benefits outweigh the risks, as long as you control sodium and saturated fat.
A Quick Shopping Guide
- Best everyday picks: Swiss cheese, part-skim mozzarella, part-skim ricotta, and no-salt-added low-fat cottage cheese. These give you the calcium and protein benefits with the least sodium.
- Good with the right label: Cheddar and Gouda both come in reduced-fat, low-sodium versions that the DASH diet explicitly includes. Don’t grab the regular block; look for “low sodium” or “reduced sodium” on the packaging.
- Worth trying: Aged cheeses like manchego or asiago in small amounts, which contain natural blood-pressure-lowering peptides. Their sodium is higher, so treat them as a flavor accent (a tablespoon grated over a dish) rather than a main ingredient.
- Limit or avoid: Feta, blue cheese, processed American cheese, and regular cottage cheese. These tend to be the highest in sodium per serving.
Portion Size Matters More Than Type
Even the lowest-sodium cheese becomes a problem if you eat enough of it. Stick to the DASH guideline of 1.5 ounces per serving, which is roughly the size of three stacked dice or a pair of dominoes. At that size, even a moderate-sodium cheese like mozzarella stays well under 200 milligrams. Double the portion and you’ve doubled the sodium, regardless of the variety.
If you’re tracking your daily total, a useful rule of thumb is to keep any single cheese serving under 200 milligrams of sodium. Check the nutrition label carefully, since serving sizes listed on packages vary between brands and don’t always match the 1.5-ounce standard. Shredding or grating your cheese rather than slicing it makes smaller amounts go further in terms of flavor, which naturally keeps portions in check.
