Although they seem like the outcast of the family of fats, omega-6 fatty acids deserve to share the spotlight. After all, you’ll find notable amounts of these fats in nutritious foods, like nuts, seeds and vegetable oils.

Despite all of the attention given to omega-3s, omega-6s are also good for your body, including your heart.

Just like all other types of fats, there are several different omega-6 fatty acids. The two most common are linoleic acid (LA) and gamma-linolenic acid (GLA). LA is an essential nutrient, meaning your body can’t make it, yet your cells need it to live. That’s where your diet comes in.

Research suggests that a high intake of omega-6s may be associated with inflammation and arthritis. This may happen as your body derives compounds called eicosanoids from these fats, which seem to increase inflammation, per the Journal of Nutrition and Metabolism.

However, a growing body of research supports a variety of benefits of omega-6s. The possible link between omega-6 fatty acids and inflammation may not be what it’s cracked up to be. A research review published in Prostaglandins, Leukotrienes & Essential Fatty Acids finds that an increased intake of certain omega-6s – arachidonic acid or linoleic acid – won’t increase inflammation and, in fact, may play a role in reducing it. To ensure this occurs, you need to pair omega-6s with a nutrient-rich diet.

Since omega-6s are unsaturated fats, they’re considered good for your heart and may lower LDL (‘bad’) cholesterol levels. A meta-analysis published in Vasa, the European journal of vascular medicine, found that a greater intake of nuts (which are high in omega-6s) is associated with a lower risk for cardiovascular disease.

What’s more, a meta-analysis in Nutrients finds that there’s no connection between omega-6 consumption and risk of cancer – and a potential for the fats to lower the risk of cancer.

Still, it’s possible that overdoing omega-6s may hinder the anti-inflammatory abilities of omega-3s.

Your overall diet naturally contains a mixture of various fats. Individual foods that contain fats, like nuts, will offer a mixture, too. For heart health, it’s advisable to eat more unsaturated than saturated fats.

Getting into specifics, many nutrition experts recommend aiming for a certain omega-6:omega-3 ratio for the healthiest approach to heart health. Research in the journal Oilseeds and Fats, Crops and Lipids suggests a 2:1 ratio. Meanwhile, research in the journal Open Heart recommends a 1:1 ratio. (In comparison, a typical Western diet can have an unbalanced ratio that’s 15:1 omega-6 to omega-3.) For adults age 19 to 50, the Institute of Medicine’s recommended adequate intake for omega-6 is 12 grams per day for women and 17 grams per day for men.

For overall good health, instead of trying to meet a strict omega-6:omega-3 ratio in your diet, think of it as a simple balancing act by letting the ratio happen naturally. Here’s how: simply add more omega-3s to your eating plan. That’s it. One way of doing this is by including your favourite omega-6-rich foods along with omega-3-rich foods in the same meal, such as adding a nutty pesto (high in omega 6s) to grilled salmon (high in omega 3s).

The typical Western diet appears to lack sufficient omega-3 fats. A scientific review in Life Sciences finds that these fats provide an anti-inflammatory effect and protect against chronic diseases. In food terms, that means if you’re not already eating a variety of foods high in these heart-friendly fats, such as salmon, sardines, mackerel and anchovies, consider giving them a boost in your eating plan. (Note that you can also get a form of omega-3s in plant foods, such as flaxseed oil, flax seeds, and chia seeds.)

Fish oil or plant-based omega-3 supplements may be beneficial, too. But do talk to your healthcare provider about the best way to include them.

Now, go ahead and enjoy the following delightful foods that offer a healthy amount of omega-6s.

Walnuts

11g omega-6 per 28g walnuts (about 14 halves)

Eating a small handful of nuts a day can boost diet quality, offer satiety, and benefit heart health. And walnuts are an excellent pick since they’re not just rich in omega-6s, they offer a significant amount of omega-3s.

According to a study in Circulation Research, people with type 2 diabetes who eat more nuts, particularly tree nuts like walnuts, may have a lower risk for cardiovascular disease.

Plus, research in Nutrients suggests that eating walnuts may offer benefits for brain health.

To punch up omega-3s: finely chop walnuts, mix with breadcrumbs and seasonings, and use a nut crust for a fatty fish, like mackerel.

As we’ve just discovered, walnuts are a great source of healthy fats. Now check out the 5 healthiest nuts you can eat.

Pine nuts

Pine nuts are rather pricey, but they do offer a wealth of nutrients, including magnesium and iron. A case-control study published in the Journal of Nutrition found that a greater intake of pine nuts, peanuts and almonds is associated with a lower risk of colorectal cancer. And there’s more good news. Animal research in Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy suggests that pine nuts may play a therapeutic role for people with diabetes due to their potential ability to manage blood glucose and oxidative stress.

To punch up omega-3s: toss pasta with garlicky sautéed fennel, canned sardines, pan-toasted pine nuts and lots of lemon.

Grapeseed oil

9.5g omega-6 per 1 tablespoon grapeseed oil

Grapeseed oil is exactly what it sounds like – the oil extracted from the seeds of grapes. It’s good for our planet as the seeds may otherwise go to waste after the process of winemaking. While grapeseed oil may not be as popular as olive oil, it’s got lots to brag about. First, it has a high smoke point, making it versatile in cooking. It’s also an excellent source of vitamin E, providing 3.9 mg per one tablespoon – that’s 26 per cent of the daily recommended amount. That’s especially important since the body needs the vitamin for a strong immune system. Plus, a research review in the journal Foods suggests that grapeseed oil may be associated with antioxidant, anti-inflammatory, antimicrobial and antitumoral activities.

To punch up omega-3s: enjoy a classic niçoise salad dressed with a grapeseed oil-based vinaigrette.

Hemp seeds

8g omega-6s per 28g hemp seeds

Although hemp seeds come from the Cannabis sativa L. plant, you won’t get ‘high’ from them. Hemp seeds don’t naturally contain THC, the psychoactive compound that’s in marijuana. They are enjoyable on top of salad and soups – and straight by the spoonful. A review published in Nutrients suggested that these unique seeds offer high antioxidant activity, which is important for protecting polyunsaturated fatty acids from oxidation. They also contain bioactive compounds which offer potential neuroprotective, antihypertensive, antioxidant and anti-inflammatory activities.

To punch up omega-3s: pulse hemp seeds, lemony mayo, seasonings and salmon in a food processor, form into patties, and grill for a superfood salmon burger.

Corn oil

7g omega-6s per 1 tablespoon corn oil

Corn oil is mild with a hint of a buttery taste. If it’s not one of your go-to cooking oils, give it a second look. A randomised crossover trial published in The Journal of Nutrition suggests that about 54 grams of corn oil per day included in a routine diet may lower total and LDL (‘bad’) cholesterol while raising HDL (‘good’) cholesterol.

What’s more, 2021 research published in the journal BMC Medicine, found that swapping non-hydrogenated vegetable oil, including corn, canola or olive oil, in place of butter or margarine (solid fats) may be associated with improved cardiometabolic health and greater life expectancy.

To punch up omega-3s: combine prepared shelled edamame, kidney beans, corn, fresh coriander and a corn oil-based lime vinaigrette for a cool side salad.

Sunflower seeds

6.5 g omega-6 per 28g sunflower seeds

Grabbing some sunflower seeds is a tasty anytime snack – and a health-protective one. A review of research published in Chemistry Central Journal notes that sunflower seeds offer an abundance of nutrients, including vitamin B6, magnesium, niacin and iron, as well as phytonutrients, including phenolic acids, flavonoids and tocopherols.

Plus, the seeds contain cholesterol-lowering phytosterols and antioxidants, while offering a myriad of potential beneficial properties, including antidiabetic, antihypertensive, antimicrobial and anti-inflammatory properties.

To punch up omega-3s: make a salad with mayo, Dijon mustard, fresh dill or tarragon and hard-cooked omega-3 eggs and serve on sunflower seed bread. Or do a DIY trail mix featuring various nuts, including walnuts, and various seeds, including sunflower seeds.
