Understanding Healthy Fats: Monounsaturated & Polyunsaturated Fats
Not all fats are the same — and some fats can actually support your health.
Monounsaturated and polyunsaturated fats are often called “healthy fats” because they can help:
✔ Support heart health
✔ Improve cholesterol levels
✔ Support brain function
✔ Reduce inflammation
Health experts encourage replacing unhealthy fats with these healthier options when possible.
What Are Monounsaturated Fats?
Monounsaturated fats (often called MUFAs) are a type of fat that may support heart health when used instead of saturated fat.
They are found mostly in plant-based foods
Common Sources:
- Olive oil
- Canola oil
- Avocados
- Nuts (almonds, cashews, peanuts)
- Seeds (sesame, pumpkin)
For example, olive oil is rich in monounsaturated fat, making up most of its fat content.
What Are Polyunsaturated Fats?
Polyunsaturated fats (PUFAs) include omega-3 and omega-6 fats.
These fats are important because:
✔ Your body cannot make them
✔ They must come from food
Polyunsaturated fats support:
- Heart health
- Brain function
- Cell growth
- Vitamin absorption
Replacing saturated fats with polyunsaturated fats has been shown to reduce the risk of heart disease
Common Sources:
- Fatty fish (salmon, tuna, sardines)
- Walnuts
- Flaxseed
- Sunflower seeds
- Soybean oil
- Corn oil
Some polyunsaturated fats — especially omega-3s — are especially helpful for heart health.
Why These Fats Matter
These healthy fats may help:
✔ Lower “bad” LDL cholesterol
✔ Support “good” HDL cholesterol
✔ Reduce risk of heart disease and stroke
Experts recommend focusing on replacing saturated fats — like butter or fatty meats — with healthier unsaturated fats instead of eliminating fat altogether.
Where You Might See Them on a Food Label
On some Nutrition Facts labels, monounsaturated and polyunsaturated fats may be listed.
However:
➡️ These are optional — not all labels include them
Even if not listed, you can still identify healthy fat sources by looking at the ingredient list.
Helpful Tips for Older Adults
Try simple swaps:
Instead of butter → use olive oil
Instead of fatty meats → choose fish
Instead of creamy sauces → use avocado
Small changes can support long-term heart health.
Balance Is Still Important
All fats — even healthy ones — contain calories.
Fat provides about 9 calories per gram, so portion awareness matters
The goal is not to eat more fat —
but to choose better types of fat.
