Nuts are one of the best vegan sources of fats, and have some protein too. But, there’s that pesky issue of having a ton of omega 6 fats, and not many omega 3 fats.
If you’re reading this, I suspect you already know why keeping a high ratio of Omega 3:6 fatty acids is a good idea, so I’ll get right into the data instead.
I collected nutritional data for all common nuts that I could think of.
If I missed any, just let me know and I’ll add it.
Omega 3:6 Ratio of Nuts Table
Here’s a table of the fats in 1 cup of each nut.
Pay special attention to the 2 columns on the far right. The actual ratio (that we want to be as high as possible) is in one of them, followed by that number multiplied by 1000 just for more convenient numbers to compare.
|Nut||Fats (g)||Omega 3 (g)||Omega 6 (g)||Omega 3:6 ratio||Ratio*1000|
Here’s a few things that you might want to takeaway from this:
- Macadamia nuts have the best omega 3:6 ratio, but also a low amount of both fats in the first place. Most of its fats are monounsaturated fats (Omega 3s and 6s are polyunsaturated fats).
- Walnuts have the 2nd best ratio, but also one of the highest raw amounts of omega 6, which is also something you want to minimize. So I’d still limit how many walnuts you eat.
- Almonds, peanuts, and Brazil nuts have essentially zero omega 3 fats and should really be eaten in limited quantities.
A Visual Look at the Omega 3 to 6 Ratio of Nuts
The chart below is the exact same data above, just in a bubble chart. You can click it to open it bigger.
The ideal nut would be far to the right, and close to the bottom.
What’s the Ideal Ratio of Omega 3 to 6 Fats?
Research suggests that humans evolved on a diet with a omega 6:3 ratio of approximately 1 (source).
More recently, particularly in Western diets, the ratio is more like 15:1 to 17:1, which causes inflammation and all sorts of health risks.
You can see in the image that the lines for omega 6 and omega 3 calories were straight until the 20th century, where they started to diverge.
While nuts certainly aren’t the driving issue of this (processed foods and cooking oils are the main ones), nuts can make our ratio worse if we already have a poor ratio.
There’s no exact optimum ratio in terms of convenience and health benefits.
But current research generally supports the idea that an omega 6:omega 3 ratio of 4:1 or below is likely close to optimal.
It’s tough to say anything beyond that at this time.
How To Get More Omega 3s to Balance Out Nuts
Hopefully that data helps you reach your nutritional targets, whatever they may be.
If you eat a lot of nuts, you’ll want to try and balance them out by getting omega 3 fats from other sources.
If you happen to be vegan, where a plant-based source is your only option, an algae-based vegan omega 3 supplement is a good option to help keep your ratio somewhat reasonable.
