Heart-healthy diet: 8 steps to prevent heart disease
4. Limit unhealthy fats
Limiting how much saturated and trans fats you eat is an important step to reduce your blood cholesterol and lower your risk of coronary artery disease. A high blood cholesterol level can lead to a buildup of plaques in your arteries, called atherosclerosis, which can increase your risk of heart attack and stroke.
The American Heart Association offers these guidelines for how much fat to include in a heart-healthy diet:
| Type of fat | Recommendation |
|---|---|
| Saturated fat | Less than 6% of total daily calories.* If you're eating 2,000 calories a day, that's about 11 to 13 grams. |
| Trans fat | Avoid |
*Note: The 2020-2025 Dietary Guidelines for Americans recommend limiting saturated fat to less than 10% of total daily calories.
There are simple ways to cut back on saturated and trans fats:
- Trim fat off your meat or choose lean meats with less than 10% fat.
- Use less butter, margarine and shortening when cooking and serving.
- Use low-fat substitutions when possible for a heart-healthy diet. For example, top your baked potato with low-sodium salsa or low-fat yogurt rather than butter, or use sliced whole fruit or low-sugar fruit spread on your toast instead of margarine.
Check the food labels of cookies, cakes, frostings, crackers and chips. Not only are these foods low in nutritional value, some — even those labeled reduced fat — may contain trans fats. Trans fats are no longer allowed to be added to foods, but older products may still contain them. Trans fats may be listed as partially hydrogenated oil on the ingredient label.

When you do use fats, choose monounsaturated fats, such as olive oil or canola oil. Polyunsaturated fats, found in certain fish, avocados, nuts and seeds, also are good choices for a heart-healthy diet. When used in place of saturated fat, monounsaturated and polyunsaturated fats may help lower your total blood cholesterol. But moderation is essential. All types of fat are high in calories.
An easy way to add healthy fat (and fiber) to your diet is to use ground flaxseed. Flaxseeds are small brown seeds that are high in fiber and omega-3 fatty acids. Studies have shown that flaxseed lowers unhealthy cholesterol levels in some people. You can grind the flaxseeds in a coffee grinder or food processor and stir a teaspoon of them into yogurt, applesauce or hot cereal.
