Omega-6 fatty acids are a key component of a healthy diet.
They’re found in many nutritious foods like nuts, seeds, and vegetable oils.
Getting a variety of these fats in a proper balance supports overall health, and this article explains how to accomplish that.
Omega-6 fatty acids are polyunsaturated fats found in a variety of foods.
Linoleic acid ⁠— often notated as 18:2 (n-6) ⁠— is one of the most common forms. Other types include arachidonic acid ⁠— 20:4 (n-6) ⁠— and gamma-linolenic acid ⁠— 18:3 (n-6).
They are considered essential fatty acids because your body needs them to function properly but is unable to produce them on its own. That means you must obtain them from foods.
On the other hand, consuming a high ratio of omega-6 to omega-3 fatty acids is thought to contribute to inflammation and chronic disease (
Some research suggests that the diets of human ancestors contained equal amounts of omega-6 and omega-3 fatty acids. But today, Western diets are significantly higher in omega-6 fatty acids with a ratio around 17:1 (
According to the Academy of Nutrition and Dietetics, women and men aged 19–50 need approximately 12 grams and 17 grams of omega-6 fatty acids per day, respectively (3).
To ensure a proper ratio, eat omega-6-rich foods in moderation and pair them with a good amount of omega-3 fatty acids from foods like fatty fish, nuts, and seeds.
Here are 10 nutritious foods high in omega-6 fatty acids, including their linoleic acid contents per serving.
Walnuts can be enjoyed on their own for a nutritious snack, or sprinkled over salads, yogurt, or oatmeal to boost the nutritional content of these meals.
Linoleic acid content: 10,800 mg per ounce (28 grams), or 38,100 mg per 3.5 ounces (100 grams) (4)
