Omega 3 to 6 Fat Ratio of Seeds [Data]

O

seeds variety

Seeds are one of the best vegan sources of fats, and also a great vegan source of calcium.

After making a page about the ratio of omega 3 to 6 fats in nuts, it only made sense to do the same for seeds.

I collected basic nutritional data for all the common seeds I could think of, and the results are just below.

If there are any seeds that I forgot, just let me know and I’ll add them.

Omega 3:6 Ratio of Seeds Table

The most important column of this table is the one on the far right.

In general, you want this ratio to be as high as possible.

Seed Fat in 100g Omega 3 (g) Omega 6 (g) Omega 3:6 ratio
Flax 42.2 22.81 5.91 3.8596
Chia 30.8 17.55 5.79 3.0311
Hemp 50 8.33 30 0.2777
Sesame 49.7 0.38 21.37 0.0178
Pumpkin 19.4 0.077 8.6 0.0090
Sunflower 51.5 0.074 23.05 0.0032

Both flax and chia are amazing sources of plant-based omega 3 fats.

But there’s a big difference between certain types of seeds. Sunflower and pumpkin seeds barely have any omega 3 fats. Their ratio is closer to the typical nut rather than flax or chia seeds.

What’s the Ideal Omega 3 To 6 Ratio?

Studies show that humans historically ate a diet with a omega 3:6 ratio of approximately 1 (source).

On the other hand, the omega 3:6 ratio of modern Western diets is more like 1:15, which is responsible for chronic inflammation and many resulting health consequences.

You can start to see where the ratio went haywire in the graph below:

omega 3 to 6 fat history

Back to our seed data, we can conclude a few things:

  • Chia and flax both have great ratios of omega 3 to 6 fats.
  • Hemp has a decent ratio of omega fats; most research seems to suggest you want at least a 1:4 ratio (0.25 in our table above), so hemp just beats this cutoff. Hemp also has a pretty good amino acid profile.
  • Other seeds aren’t so great – When it comes to the other seeds, they’re clearly not good sources of omega 3 fats. You should limit your intake of sesame, pumpkin, and sunflower seeds.

Seeds have a much better ratio than nuts for omega 3s and 6s, but certain ones are clearly better than others.

Other Ways to Get Omega 3 Fats

If you eat a lot of those “bad” seeds, you can attempt to balance out your polyunsaturated fat intake by getting more omega 3s from other sources.

If you eat fish, that’s the best source.

If you don’t for whatever reason, an algae-based vegan omega 3 supplement is a good alternative that is the easiest way to get omega 3s from plants. It’s really the only other realistic option on a plant-based diet.

Limit, But Don’t Eliminate Seeds

While you don’t want to go overboard on certain seeds, they are all packed with nutrients.

For example, sunflower seeds are the best plant-based source of vitamin E, while pumpkin seeds have a lot of zinc and magnesium.

Eat a variety of seeds if possible, just don’t overdo it.
