Wild rice's inclusion on this list should come as no surprise -- because it's not a rice, but a grass. (For that matter, it's not always wild. Most so-called wild rice in North America is grown on farms.) As you may have predicted from our previous discussions on pasture-raised meat and dairy foods, being a grass makes it a likely candidate for high omega-3 content. Wild rice is not only a good source of omega-3, but contains only slightly more omega-6, for a ratio of about 1.25:1 [source: NutritionData].
White and brown rice, on the other hand, are grains. Grains offer nutritional benefits of their own. But again, grain-based feeds are responsible for the high levels of omega-6 acids found in conventionally produced foods from animals, so make sure you're buying wild rice if you've got omega-3 in mind.
