Cooking With Healthy Oils: The Secret to Anti-Inflammatory Meals
Healthy oils can quell chronic, systemic inflammation—a condition that significantly exacerbates the risks of cardiovascular illness, autoimmune conditions and neurodegenerative diseases like Alzheimer’s and Parkinson’s. Beneficial fats are indispensable for metabolic processes, brain function, hormone production and the absorption of vitamins A, D, E and K. For overall well-being, the optimal choices are cold-pressed, anti-inflammatory oils made from avocados, walnuts and flaxseeds, as well as extra virgin olive oil and modest amounts of virgin coconut oil.
Inflammatory Fats
The typical American diet of drive-through meals and processed, packaged foods like salad dressing, ketchup, mayonnaise and sweet treats in the cookie aisle contains refined vegetable and seed oils. Whether it’s safflower, sunflower, corn, soybean, canola or cottonseed oil, these polyunsaturated fatty acid oils are often bleached, deodorized and chemically extracted with hexane to ensure a greater, more cost-effective yield with a longer shelf life. Such refinement methods destroy the naturally occurring antioxidants. Consequently, a diet high in ultra-processed foods containing seed and vegetable oils can increase systemic inflammation.
“Polyunsaturated fatty acids have multiple double bonds in their carbon chains. This structure makes them fragile and prone to becoming inflammatory compounds,” explains Sara Banta, a health coach and supplement specialist in Newport Beach, California. “They also inhibit fatty acid beta-oxidation, making your body less efficient at using fat for fuel and leading to larger fat cells.”
Healthy Oils
Avocado Oil: Rich in monounsaturated fats and vitamin E, avocado oil is a versatile choice for moist muffins, roasted vegetables and flavorful homemade salad dressings. With a high smoke point, avocado oil is perfect for savory stir-fries and mouth-watering, healthy grills. In a study published in Disease Markers involving rat subjects, avocado oil was found to partially reverse inflammatory processes and reduce levels of triglycerides and low-density lipoprotein (“bad” cholesterol), without affecting high-density lipoprotein (“good” cholesterol) levels. Banta cautions, “Most avocado oils are cut with seed oils. In fact, over 60 percent of the avocado oils are not pure avocado oil, so buyer beware. Look for a brand you trust that is organic.”
Olive Oil: Consider using extra-virgin olive oil, an important culinary staple that offers impeccable health properties and delicious flavor to appetizers, dipping sauces, salads and sautés. Studies have reported that regular consumption of olive oil may be linked to lower levels of certain markers of inflammation, including C-reactive protein and interleukin-6, as well as a lower risk of dying from cardiovascular disease. Banta notes that olive oil is a heart-healthy choice because of its high levels of monounsaturated fats and antioxidants, and a perfect oil for dressings and low-heat cooking. Organic, cold-pressed olive oil is the best option because it is processed without using high heat or chemical solvents.
Walnut Oil: According to a 2023 review published in Antioxidants, drizzling walnut oil over a grain bowl or grilled salmon may help prevent chronic inflammatory diseases and cancer. Rich in polyunsaturated fatty acids and prebiotics, it was found to promote the growth of beneficial gut bacteria, as well as urolithin, a potent natural compound with antioxidant and anti-inflammatory properties.
Alpha-Linolenic Acid: Mayo Clinic suggests that alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid found in flaxseed oil, might help individuals with heart disease or women going through menopause. Flaxseed oil offers its powerful nutrients best when used unheated and can be whipped up in smoothies, sprinkled on soup, drizzled over salads or cottage cheese and added to protein-packed nut butter energy balls.
Coconut Oil: When used in moderation, coconut oil is also a versatile option in the kitchen for sautés, desserts, curries and healthy breakfast shakes. Research published in the Journal of Nutritional Science in 2024 suggests that this lauric acid-rich oil lowers inflammation and relieves COVID-19 symptoms. “Coconut oil offers numerous health benefits due to its unique composition and stability at high temperatures,” says Banta. “Rich in medium-chain triglycerides, coconut oil provides a quick and efficient energy source, supporting metabolism and promoting fat burning.”
Eating Out
When eating out, be mindful that most salad dressings and marinades are likely to contain highly processed, inflammatory oils. To minimize ill effects, Banta recommends asking for salad dressing on the side or replacing it with vinegar or lemon; requesting that the chef use the healthier option of real butter instead of vegetable or seed oil; and avoiding fried foods.
