Top 10 Foods with the Highest Omega 3 to Omega 6 Ratio

Research suggests that eating a diet with a high omega-3 to omega-6 ratio leads to a reduced risk of some cancers, cardiovascular disease, inflammation, developmental disorders, and cognitive aging. (1,2)

This article lists the foods with the highest omega-3 to omega-6 ratio, so that you can achieve a better balance in your diet.

Foods with a high omega-3 to omega-6 ratio include crab, fish (tuna, cod, salmon), mussels, rapini, spinach, flax seeds, mangoes, lettuce, and kidney beans.

There is no daily value set for omega-3s, but the adequate intake (AI) per day is set at 1600mg. This is used to calculate the AI of omega-3 for the foods in the list.

Below is a list of foods with high omega 3 to omega 6 ratios, for more, see the list of foods high in omega 3s, and the complete ranking of over 200 foods high in omega 3s per omega 6.

Do Leafy Greens like Broccoli Raab, Spinach, and Lettuce really have Omega 3 fats?

While it is surprising, leafy greens like lettuce and spinach do contain omega 3 fats; specifically, alpha-linolenic acid (18:3).

While a cup of butterhead lettuce only has 0.1g of fat, this is equivalent to 1000mg of fat. Of those fats 0.046g or 46mg are alpha-Linolenic acid or (18:3).

Viewing the data directly from the USDA we see that 100 grams of butterhead lettuce provides even more than a cup, with 0.083g or 83mg of ALA. This is listed under 18:3 on the USDA website.

While there are many plant foods higher in Omega 3 fats, you don't want to discount leafy green as a source of healthy fats in your diet. A large salad can get you far in meeting your 1600mg recommended daily intake (RDI) for Omega 3s.
