Understanding Dietary Fats: What to Choose, Limit, and Avoid

Not all fats are the same. Some fats support heart health and overall wellness, while others can increase the risk of heart disease when eaten too often. The goal isn’t to avoid fat entirely — it’s to choose the right types more often.

Best Choices: Heart-Supportive Fats

These fats can help support healthy cholesterol levels when used in moderation.

Common sources include:

Olive, avocado, and canola oils
Nuts and seeds (almonds, walnuts, sunflower seeds)
Avocados
Fatty fish such as salmon, trout, sardines, and tuna

Why they matter:

Help improve cholesterol balance
Provide essential fatty acids the body cannot make on its own
Support heart and blood vessel health

Use Sparingly: Higher-Risk Fats

These fats can fit into an overall healthy pattern but should be limited.

Common sources include:

Butter, cream, and full-fat dairy products
Cheese
Fatty cuts of red meat
Bacon and sausage

Things to know:

Can raise LDL (“bad”) cholesterol levels
Often found in larger amounts in processed or restaurant foods

Best to Avoid When Possible: Unhealthy Fats

These fats offer little health benefit and can increase heart disease risk.

Common sources include:

Foods made with partially hydrogenated oils
Fried foods from fast-food restaurants
Commercial baked goods (donuts, pastries, cakes)
Some shelf-stable snack foods

Why to limit them:

Increase inflammation and cardiovascular risk
Raise harmful cholesterol levels
Often hidden in processed foods

Simple Ways to Make Healthier Fat Choices

Cook with plant-based oils instead of butter or shortening
Choose grilled, baked, or roasted foods instead of fried
Read ingredient lists for “hydrogenated” or “partially hydrogenated” oils
Add nuts, seeds, or avocado to meals for flavor and texture
Enjoy higher-fat foods in smaller portions

The Big Picture

Healthy eating isn’t about cutting out entire food groups. It’s about balance, variety, and choosing fats that support your heart more often than those that don’t.

Small swaps — made consistently — can lead to meaningful health benefits over time.
