A Heart-Healthy Fat You Shouldn’t Overlook
When we think of healthy fats, omega-3 and omega-6 often steal the spotlight. But there’s another important player in the world of fatty acids — omega-9.
While not considered “essential” (your body can produce it), omega-9 fatty acids still offer a wide range of health benefits, especially for the heart, brain, and metabolism. And the best part? You can easily get them from delicious, everyday foods.
Let’s dive into the properties, benefits, and best food sources of omega-9 fatty acids.
What Are Omega-9 Fatty Acids?
Omega-9s are a type of monounsaturated fat. The most common form is oleic acid, which makes up a large portion of olive oil and other plant-based fats.
Unlike omega-3 and omega-6, omega-9 is non-essential, meaning your body can synthesize it if you have enough of the others. Still, consuming omega-9-rich foods can help maintain balance in your fat intake and support various aspects of health.
Health Benefits of Omega-9
1. Supports Heart Health
- Helps reduce bad LDL cholesterol and increase good HDL cholesterol
- May lower the risk of heart disease, stroke, and atherosclerosis
2. Boosts Brain Function
- Omega-9 contributes to healthy brain cell membranes and may support cognitive function, memory, and mood
- May reduce inflammation linked to neurodegenerative diseases
3. Reduces Inflammation
- Helps balance the body’s inflammatory response, especially when consumed alongside omega-3s
- May ease chronic inflammation and improve joint health
4. Aids in Weight Management and Metabolism
- May enhance fat burning and insulin sensitivity
- Linked to improved blood sugar control, especially in people with type 2 diabetes
5. Supports Healthy Cells
- Strengthens cell membranes and protects against oxidative stress
- Plays a role in skin health and immune function
Foods Rich in Omega-9 Fatty Acids
Many delicious and widely available foods are naturally high in omega-9, particularly oleic acid:
🌿 Plant-Based Oils:
- Olive oil (extra virgin is best)
- Avocado oil
- Almond oil
- Canola oil (non-GMO and organic recommended)
- Hazelnut oil
🥜 Nuts and Seeds:

Omega-9 in Balance: A Word on Fat Ratios
Though omega-9 is beneficial, the key to optimal health is balance:
- A healthy diet should include omega-3s, omega-6s, and omega-9s in the right proportions.
- The Mediterranean diet, which is naturally rich in omega-9 from olive oil and nuts, is a great model to follow.
- Try to replace saturated and trans fats with omega-9-rich monounsaturated fats for better cardiovascular outcomes.
Omega-9 fatty acids may not be “essential” in the technical sense, but their impact on health is anything but optional. From supporting your heart and brain to balancing inflammation and blood sugar, they offer powerful protective benefits.
By including olive oil, avocados, nuts, and seeds in your daily meals, you’ll easily fuel your body with the omega-9s it needs to thrive.
