Choosing the right fats isn’t about eating “fat-free”—it’s about swapping unhealthy fats for better ones. U.S. Dietary Guidelines emphasize limiting saturated fat (from fatty meats, butter, full-fat dairy, some baked goods) and keeping trans fat as close to zero as possible, while choosing unsaturated fats from foods like olive or canola oil, nuts, seeds, avocados, and fatty fish. These swaps can help improve LDL (“bad”) cholesterol and support heart health. In practice, that means cooking with oils instead of butter, picking fish or beans over processed meats, choosing low-fat dairy, and reading labels for hidden saturated/trans fats. The sections below translate those principles into simple meal ideas, shopping tips, and cooking habits.
Choose heart-smart fats, limit saturated fat, avoid trans fat—aligned with U.S. Dietary Guidelines and AHA.

Why This Matters
Small kitchen choices add up. Swap butter for olive oil, pick salmon over processed meats, and keep nuts or seeds on hand. U.S. guidance is consistent: limit saturated fat, avoid industrial trans fat, and lean on unsaturated fats from plants and fish.

Dietary Guidelines
The Dietary Guidelines for Americans (2020–2025) advise keeping saturated fat under 10% of calories from age 2 onward. On a 2,000-calorie day, that’s about ≤22 g. The practical message: shift toward plant oils, nuts, seeds, and seafood.

Healthy vs. Unhealthy Fats: Quick Map
- Choose more often (unsaturated): olive, canola, avocado, peanut, soybean oils; almonds, pistachios, walnuts; pumpkin/sunflower seeds; salmon, sardines, trout.
- USDA MyPlate (Oils): https://www.myplate.gov/eat-healthy/more-key-topics
- Go easy on (saturated): butter, ghee, lard, full-fat cheese, high-fat cuts of beef/pork, coconut and palm oils.
- AHA on Saturated Fat: https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/fats/saturated-fats
- Skip (industrial trans fat): the FDA removed partially hydrogenated oils (PHOs), but still scan labels.
Grocery Swaps (Easy Wins)
- Butter → olive or canola oil for stovetop cooking
- Creamy dressing → vinaigrette (olive oil + lemon + Dijon)
- Deli meats → tuna or salmon (water/olive-oil pack)
- Daily full-fat cheese → rotate with nuts, hummus, plain yogurt (watch added sugar)

Label Reading for U.S. Shoppers
Three quick checks on Nutrition Facts:
- Saturated fat: lower per serving is better

Why Swaps Work (Evidence Snapshot)
Replacing saturated fat with polyunsaturated (and, to a lesser extent, monounsaturated) fats improves LDL-cholesterol and supports heart health. Swapping saturated fat for refined carbs doesn’t help.
