How much
How much fat should I eat a day?20 to 35% of your calories, about 44 to 78 g on 2,000. The kind of fat counts for more than the total, so keep saturated fat under 10%.
How much fat should I eat on 1,500 calories?About 33 to 58 g of fat, with saturated fat under 17 g. A tablespoon of butter would be 7.2 of those.
How much saturated fat should a woman eat a day?The same 10% line as everyone. On 1,600 calories that's about 18 g, on 1,800 about 20 g, so the label's 20 g can be more than your line.- How much saturated fat should I eat a day?Under 10% of your calories: about 22 g on 2,000 calories, 17 g on 1,500, 28 g on 2,500 (2025 to 2030 US guidelines). The tool works out yours.
How much saturated fat should I eat with high cholesterol?Under 10% is the US line for everyone. With high LDL, swapping saturated fat for vegetable oils is the change that moves it. cholesterol.guide sizes it for your number.
Is 20 g of saturated fat a day too much?On 2,000 calories it's 9%, just under the line. On 1,500 it's 12%, over. The 20 g on labels is a fixed Daily Value, so check it against your own calories.
Saturated fat
- Is saturated fat bad for you?It raises LDL, and in 15 trials cutting it meant 17% fewer heart events. Swap it for olive, canola or other plant oils, the swap with the best evidence.
- What are healthy fats?Mostly the unsaturated ones in olive and canola oil, nuts, seeds, avocado and oily fish. Eaten in place of butter and fatty meat, they lower LDL.
- What foods are high in saturated fat?Coconut oil (11.2 g a tablespoon), butter (7.2), cheese (6.0 an ounce), fatty beef, cream and pastry. In US diets, sandwiches and burgers carry the most.
- What is saturated fat?Fat whose chains are straight, so they stack tight and stay solid at room temperature. Butter, cheese, fatty meat, coconut and palm oil have the most.
What's the easiest way to cut saturated fat?Change your cooking fat. Olive or canola oil in place of a daily tablespoon of butter takes off 5.4 to 6.2 g, about a quarter of your line, with one bottle.
Why does saturated fat raise cholesterol?It slows the liver's LDL receptors, the drain that pulls LDL out of the blood, so more stays in. cholesterol.guide has the numbers.
Oils and spreads
Avocado oil or olive oil?They're close cousins, both mostly monounsaturated with 1.6 to 1.8 g of saturated fat a tablespoon. In one lab test the olive oil smoked later. Pick by taste.- How much saturated fat is in butter?7.2 g a tablespoon, about a third of a 2,000 calorie day's line. About 62% of butter's fat is saturated. Ghee is the same fat, a little more concentrated.
Is beef tallow healthy?The 2026 guidelines list it as an option, after olive oil. A tablespoon has 6.4 g of saturated fat, about half its fat. Use it for flavor, and count it.- Is butter worse than olive oil?For your heart, yes. Butter has 7.2 g of saturated fat a tablespoon, olive oil 1.8. Swapping 10 g of butter a day for plant oils went with 17% fewer deaths.
Is canola oil bad for you?No. It has 1.0 g of saturated fat a tablespoon, near the lowest of any oil, and in a 33-year US study more canola went with fewer deaths. Long frying is its weak spot.
Is coconut oil healthy?It's the most saturated cooking fat, about 83%, and raised LDL about 10 mg/dL against plant oils in 16 trials. Use it for flavor and keep a plant oil for every day.- Olive oil or canola oil?Keep both. Extra virgin olive oil for most cooking, since it held up best to heat in a lab test, and canola for baking. Both lower LDL in place of butter.
- What is the healthiest cooking oil?Extra virgin olive oil for most cooking. It's low in saturated fat and, averaged over two lab heat tests, broke down the least. Canola when you want no taste.
- What is the smoke point of olive oil?In one lab test, extra virgin olive oil smoked at 404 °F (207 °C) and, averaged over two heat tests, made the fewest breakdown compounds of ten oils.
Omega-3 and fish
Can fish oil cause an irregular heartbeat?In seven big heart trials, fish oil raised the risk of atrial fibrillation about 25%, and about half above 1 g a day. Ask your doctor before high doses.
How do vegans get omega-3?ALA is easy from flax, chia and walnuts, but the body turns only a little into EPA and DHA. Algae oil carries EPA and DHA directly, from the sea algae that make them.- How many fish oil capsules should I take a day?Check the back of the bottle, since a 1,000 mg capsule means 1,000 mg of oil. Eat fish first. Over 1 g a day of EPA and DHA, talk to your doctor.
How much fish should I eat while pregnant?The FDA says 8 to 12 ounces a week while pregnant or breastfeeding, 2 to 3 servings from its lowest-mercury list, like salmon, sardines and trout.- How much omega-3 do I need a day?The US advice is fish: at least 8 ounces a week. Of salmon, sardines or trout, that's about 280 to 700 mg of EPA and DHA a day. The counter does yours.
What foods are high in omega-3?Oily fish, like salmon, herring, mackerel, sardines and trout, for EPA and DHA. Chia, walnuts, ground flax and canola oil for the plant kind. Food first, capsule second.
Which fish has the most omega-3?Farmed salmon and herring lead the common fish, about 1.7 to 1.8 g of EPA and DHA in 3 oz. Sardines and trout have about 0.8, canned light tuna 0.2.
Fat in foods
- How much fat is in an avocado?About 5 g an ounce (a fifth of one), mostly monounsaturated, with under 1 g saturated. A whole one has about five times that.
- Is cheese high in saturated fat?Yes. An ounce of cheddar has 6.0 g, more than a quarter of a 2,000 calorie day's line. Strong cheese goes further, so you can use less.
Is full-fat dairy healthy?The 2026 guidelines say include it, with no added sugar, and keep saturated fat under 10%. A cup of whole milk has 5.1 g, so count it.- Should kids drink whole milk?Pediatricians advise whole milk from 1 to 2, then lower-fat milk. The 2026 US guidelines favor full-fat dairy for kids, and schools can serve whole milk again.
Special cases
Why do fatty foods make me nauseous on Ozempic?GLP-1 drugs slow how fast the stomach empties, and a big fatty meal slows it more. Smaller meals with less fat usually sit better.- Why is my LDL high on keto?Butter, cream and fatty meat can push LDL up a lot in some people. Keep the carbs low and change the fat. The study saying plaque didn't follow it was retracted in 2026.
