What’s The Optimal Omega-6 to Omega-3 Ratio?

Is your diet healthy for your heart? You might be missing a key piece: the balance between omega-6 and omega-3 fatty acids. Turns out, too much of one disturbs this balance.


We've all been told fats are bad, right? But the reality is, some fats are good for you. Especially these things called polyunsaturated fats, like omega-3s and omega-6s. These fatty acids are your friends in keeping inflammation down and helping your brain work properly.
People might tell you to eat more fish and nuts to get more omega-3 and omega-6 in your system. But it's not just about eating more of them, it's about getting the right balance. That is what we call the omega-6 to omega-3 ratio.
What Are Omega-6 and Omega-3 Fatty Acids?
Let's start with the basics. Polyunsaturated fats lower your LDL, or bad cholesterol. These fats are important for your brain and cell growth. Since our bodies cannot produce these fatty acids, we need to get them from food.
Omega-6 fatty acids are important in cell signaling and inflammation. Now, Omega-6s aren't naturally bad for you. In fact, when they come from whole foods like nuts and seeds, they can even improve your heart health. The problem is, too much Omega-6 from processed foods contributes to chronic inflammation.
On the other hand, Omega-3 fatty acids have anti-inflammatory properties for your heart and brain. They’re found in fatty fish like salmon, and plant-based sources like flaxseeds and chia seeds. Omega-3 has different types:
- Eicosapentaenoic Acid (EPA): This is useful for heart health.
- Docosahexaenoic Acid (DHA): This is good for brain and eye health.
- Alpha-Linolenic Acid (ALA): This is a plant-based omega-3 found in flaxseeds, chia seeds, and walnuts. The body still needs to convert ALA into EPA and DHA.
Omega-6 to Omega-3 Ratio Explained

This ratio compares how much omega-6 you eat to how much omega-3 you consume. In the past, human diets had a balanced ratio of about 1:1. This means equal amounts of both fats.
But now, that ratio has changed because of processed foods and vegetable oils. Many now have unhealthy ratios as high as 15:1 or even 20:1, with more omega-6s.
When the ratio is not balanced, it may be linked to chronic inflammation. This especially happens when you have too much omega-6. That puts you at risk of Coronary artery disease, hypertension, high total cholesterol, and stroke. It also leads to arthritis, autoimmune diseases, and mental health issues.
What is the Ideal Omega-6 to 3 Ratio?
So, what’s the optimal ratio of omega-6 to omega-3 fatty acids in your diet? While recommendations vary slightly, most experts agree that a ratio closer to 1:1 to 4:1 is ideal. When your fatty acids are balanced, it reduces your inflammation. It also improves your heart health and boosts your brain function.
Balancing Omega-3 and 6: What You Can Do

- Adjust Your Diet: Eat more foods high in omega-3 and low in omega-6. Think salmon, mackerel, flaxseeds, chia seeds, and walnuts. The Dietary Guidelines for Americans 2020-2025 recommends a daily intake of 1.1 to 1.6 grams of omega-3 fatty acids. According to the American Heart Association, two servings of fish (3 to 4 ounces each) weekly are a good source of omega-3. You should also limit processed foods and vegetable oils rich in omega-6. Go for plant-based cooking oil like olive or avocado oil.
- Use Omega-3 Fish Oil Supplements: It’s more effective to increase your omega-3 while reducing omega-6 fats. If you’re struggling to get omega-3 from your diet, you can take Omega-3 supplements like fish, krill, or algae oil. Fish oil supplements usually have around 300 milligrams per pill. When choosing supplements, focus on quality and purity. You can ask your doctor for the right dose.
- Change Your Lifestyle: In addition to diet and supplements, some lifestyle changes can help. Manage stress and exercise regularly to lower inflammation. Also, learn to read labels to make better choices while shopping for food.
