What You'll Learn
Eat more walnuts, tofu, hemp seeds, and peanut butter
Linoleic acid is an omega-6 polyunsaturated fatty acid that occurs naturally in a wide variety of foods, especially nuts and seeds. If you're looking to add more of it to your diet, consider eating more walnuts, tofu, hemp seeds, and peanut butter.
Walnuts are an excellent source of alpha-linolenic acid (ALA), the plant-based omega-3 essential fatty acid. A one-ounce serving of walnuts provides 2.5 grams of ALA. As one of the best plant food sources of omega-3s, walnuts are a great way to add more linoleic acid to your diet.
Tofu, made from soybeans, is another good source of linoleic acid. Soybean oil is also a source of linoleic acid, so using it in your cooking can help you add more to your diet.
Hemp seeds are technically a nut, and they are very nutritious. They are a great source of protein, with more than 25% of their total calories coming from high-quality protein. They are also rich in healthy fats and essential fatty acids, including linoleic acid (omega-6) and alpha-linolenic acid (omega-3). Eating hemp seeds may also reduce your risk of heart disease, as they contain high amounts of the amino acid arginine, which produces nitric oxide, helping to lower blood pressure.
Peanut butter is another good source of linoleic acid, as peanuts are often included in lists of foods that are high in this fatty acid.

Choose corn-free, soy-free animal products
Linoleic acid is an omega-6 polyunsaturated fatty acid (PUFA) that occurs naturally in a wide variety of foods, especially nuts, seeds, and vegetable oils. It is considered an essential fatty acid because it cannot be synthesized by the human body.
While modest amounts of linoleic acid support human health, excessive intake has been linked to various illnesses, including cardiovascular disease, cancer, and Alzheimer's disease. This is because linoleic acid is prone to oxidation, forming harmful byproducts known as oxidized linoleic acid metabolites (OXLAMs).
To reduce your linoleic acid intake, it is recommended to avoid seed oils and processed or pre-packaged foods with high linoleic acid levels. When dining out, be mindful that restaurants often use high linoleic acid oils for cooking, so consider ordering grilled meat, seafood, or vegetables without added oils.
When it comes to choosing corn-free and soy-free animal products to reduce linoleic acid intake, it is important to understand the feeding practices of different animals. Here are some guidelines to follow:
- Poultry, including chicken, is typically fed a diet that includes corn and soy. Soy is a popular choice due to its high protein content, which supports growth and egg production. However, some producers are exploring soy-free feeds due to health concerns and production issues. If you're raising chickens, you can consider corn and soy-free feeds like Organic Fertrell Poutry Nutri-Balancer, which provides omega-6 fatty acids and protein.
- Meat from grass-fed animals, such as beef and lamb, tends to have higher levels of linoleic acid. To minimize linoleic acid intake, opt for meat from animals fed a corn-free and soy-free diet.
- Farm-raised fish often have higher levels of linoleic acid due to their diet. Choose wild-caught fish and shellfish, which have lower linoleic acid levels as they feed on natural, species-appropriate diets.
- Eggs can also contain linoleic acid, with chicken eggs being supplemented with grains high in linoleic acid to increase weight. To reduce linoleic acid intake, opt for eggs from corn-free and soy-free sources.
By choosing corn-free and soy-free animal products, you can effectively reduce your linoleic acid intake and potentially lower your risk of associated health issues. However, it is important to note that completely eliminating linoleic acid from your diet may not be necessary, as it offers health benefits when consumed in moderation.

Consume wild-caught fish and shellfish
Linoleic acid is an omega-6 fatty acid that is essential for human nutrition as it cannot be synthesized by the human body. While it is important to consume linoleic acid, it is also crucial to maintain a proper balance of omega-3 and omega-6 fatty acids in the diet. Excessive intake of linoleic acid has been linked to various health issues, including inflammation, obesity, and chronic diseases such as cardiovascular disease and Alzheimer's.
To add linoleic acid to your diet in a healthy way, it is recommended to consume wild-caught fish and shellfish. Farm-raised fish often contain higher levels of linoleic acid due to their diet, which typically includes corn and soy that are high in linoleic acid. On the other hand, wild-caught fish and shellfish have lower levels of linoleic acid because they feed on natural, species-appropriate diets.
When consuming wild-caught fish and shellfish, it is important to choose a variety of species to maximize the benefits. For example, longtail shad, yellowstripe scad, and moonfish are good sources of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA), respectively. At the same time, fringescale sardinella, malabar red snapper, black pomfret, Japanese threadfin bream, giant seaperch, and sixbar grouper are excellent sources of omega-3 fatty acids.
It is worth noting that the way you prepare your wild-caught fish and shellfish can also impact your linoleic acid intake. Ordering grilled or pan-seared seafood with vegetables and no added oils can help reduce your exposure to high-linoleic acid cooking oils. Additionally, when dining out, it is advisable to avoid pre-packaged or prepared foods, as they often contain vegetable oils with high levels of linoleic acid.
By incorporating a variety of wild-caught fish and shellfish into your diet and preparing them in a healthy manner, you can effectively increase your intake of linoleic acid while also benefiting from the other nutrients and omega-3 fatty acids that these seafood options provide.
