How much saturated fat should I eat with high cholesterol?
The US line is the same for everyone, under 10% of your calories, about 22 g on 2,000. With high LDL, what you eat in its place counts most. Swapping butter, cheese and fatty meat for olive, canola and other vegetable oils is the food change that lowers LDL.
After a high cholesterol result, it’s tempting to look for one food that fixes it. On the fat side, the move with the most evidence is less exciting. You find where your saturated fat comes from and replace the biggest piece of it. Saturated fat turns down the liver’s LDL receptors, the drain that pulls LDL out of your blood, and unsaturated fats turn them back up (why that happens).
What we’d do, in this order:
- Find your biggest source. Put a usual day into the scorer below. For most people it’s butter, cheese or fatty meat.
- Swap that one food for a vegetable oil. Olive oil in the pan in place of a tablespoon of butter takes 7.2 g of saturated fat down to 1.8 g.
- Retest in about two to three months, at the same lab, so you see what the swap did for you.
How much your LDL should fall for a given swap depends on your starting number, and cholesterol.guide works that out.
What the trials found
In a 2020 Cochrane review of 15 trials with 56,675 people followed for at least two years, cutting saturated fat lowered heart attacks, strokes and other heart events by 17%. Bigger cuts went with bigger effects. Replacing it with polyunsaturated fat or with carbohydrate both looked useful, and the data on monounsaturated fat were too thin to judge.
The best evidence for one specific swap comes from 221,054 US adults followed for up to 33 years. Replacing 10 g of butter a day, about two thirds of a tablespoon, with plant oils went with 17% fewer deaths. It’s an observational study, so people who ate more oil and less butter may have differed in other ways, and the authors say so.
How low should you go?
The 2026 US guidelines set one cap, “saturated fat consumption should not exceed 10% of total daily calories,” and don’t give a lower one for people with high cholesterol. In the Cochrane trials, the more people cut, the more it helped, so going well under your line is likely to do more than sitting right at it.
| Calories a day | The 10% line |
|---|---|
| 1,500 | 17 g |
| 1,800 | 20 g |
| 2,000 | 22 g |
| 2,500 | 28 g |

If you take a statin
Keep taking it. Food changes add to what a statin does, and a statin is never stopped on your own. Your doctor decides whether food is enough for your number. The check-it-worked guide covers the retest.
