Is cheese high in saturated fat?
Yes. An ounce of cheddar has 6.0 g of saturated fat, more than a quarter of the 22 g line for a 2,000 calorie day. Two ounces on a sandwich or a plate of nachos is more than half.
Cheese doesn’t look like a fat. It looks like protein, and it is, about 7 g in an ounce of cheddar. But it’s also 9 g of fat, and two thirds of that fat is saturated. It hides inside other foods too. The 2020 to 2025 US guidelines found that the top sources of saturated fat for adults are sandwiches, including grilled cheese, burgers, tacos and burritos, and mixed dishes like casseroles and quesadillas, where cheese does a lot of the work.
What we’d do: keep cheese and shrink it. Aim for about an ounce a day, use a strong one like aged cheddar or parmesan so a little goes further, and put avocado on the sandwich in its place now and then.
Cheese by the portion
| Cheese (USDA) | Saturated fat | Share of a 22 g line |
|---|---|---|
| Cheddar, 1 oz | 6.0 g | 27% |
| Cheddar, 2 oz | 12.0 g | 54% |
| Cottage cheese, 4% fat, 1 cup | 6.0 g | 27% |
| Cottage cheese, 2% fat, 1 cup | 2.8 g | 13% |
| Parmesan, grated, 1 tbsp | 1.0 g | 5% |
A tablespoon of grated parmesan has a sixth of the saturated fat of an ounce of cheddar, and enough flavor to finish a bowl of pasta. Switching from 4% to 2% cottage cheese saves 3.2 g a cup.
How it adds up in a day
Two ounces a day is an easy amount to reach, with a slice at lunch and some on dinner. That’s 12 g of saturated fat, more than half of a 2,000 calorie line, from cheese alone. Add a tablespoon of butter and you’re at 19.2 g before any meat. Cut back to one ounce and the day drops by 6 g.
The guidelines’ own suggestions are lower fat cheese in mixed dishes, and avocado, nuts or seeds in place of cheese. Two ounces of avocado has 1.4 g of saturated fat, against 6.0 g for an ounce of cheddar.
The new guidelines
The 2026 US guidelines say to include full-fat dairy with no added sugars, and they keep the saturated fat cap at 10% of calories in the same short document. Cheese is the dairy food where those two lines pull hardest against each other, since an ounce is more than a quarter of the line. Is full-fat dairy healthy? has the rest, and if cheese is the biggest source in your week, the quiz calls it The Cheese Board and gives you the swap.
