A Deep Dive into Seed Oils: Extraction, Health Concerns, Alternatives: To ditch or not to ditch?

Does it feel like every day something is either bad or good for you that wasn’t the day before? Yeah, I know! Sometimes it feels like I have no idea what to eat. Is this good or bad? Will that make me sick or healthy? Sugar was bad, now it’s better than corn syrup and some labels are actually saying, “Made with real sugar!” One day coffee is bad and the next it helps with all sorts of things. What gives? OK, so the latest thing is “NO SEED OIL!” I suppose that makes sense.

What Exactly Is Seed Oil?

What exactly are these seed oils everyone’s talking about? Simply put, they’re oils extracted from the seeds of various plants. Think of things like sunflower seeds, soybeans, rapeseed (which gives us canola oil), and even corn. These little seeds are packed with oil. While some oils are obtained through simple pressing. The extraction of many common seed oils involves more industrial processes to yield more oil. This often involves the use of chemical solvents, such as hexane, which is derived from petroleum. This results in a less expensive product with a neutral flavor, making them versatile for all sorts of dishes. The methods used to extract these oils from seeds are a central point of debate. This is particularly true for the use of petroleum-based solvents and is detailed in the links below.

The Evidence, Or Lack There Of (you decide)

What’s Your Verdict?

So, after exploring those different perspectives, what are your thoughts? It’s certainly a lot to consider, and honestly, I’m still processing it all myself. In our household, we’ve leaned towards using non-seed oils for everyday cooking, but I still find myself reaching for corn or canola oil when I’m baking. I’m even curious enough to try avocado oil in my next cake! To help us all navigate this, I’ve put together a list of common “healthy” oils, outlining their potential benefits, drawbacks, and some helpful tips for incorporating them into your cooking.

The “Healthy” Oils

Olive Oil:

• Pros:
  • Adds a rich and often desirable fruity or peppery flavor to many dishes. This can range from salad dressings and marinades to sautéed vegetables and roasted meats.
  • Rich in monounsaturated fats, particularly oleic acid, which is well-regarded for its heart-healthy benefits.
  • Versatile for various cooking methods, though its flavor profile is most pronounced in lower-heat applications and as a finishing oil.
  • When used in baking, it can contribute to a moist and tender crumb
• Cons:
  • The distinct flavor can be overpowering or clash with certain recipes, especially those requiring a more neutral taste
  • Its lower smoke point compared to some other oils makes it less ideal for high-heat cooking methods like deep-frying.
  • In baking, its strong flavor might not complement all recipes, particularly delicate cakes or cookies. It can also sometimes cause cookies to spread more, resulting in a flatter, crisper texture.

Tips for Cooking with Olive Oil:

• Consider the flavor intensity: Extra virgin olive oil has the most pronounced flavor, while lighter or refined olive oils have a milder taste. Choose accordingly for your dish.
• Be mindful of heat: For high-heat cooking, opt for light or refined olive oil, which has a slightly higher smoke point than extra virgin.
• Use extra virgin olive oil generously in dressings and as a finishing touch to appreciate its full flavor and health benefits.
• Experiment in baking: If you enjoy the flavor, try it in more rustic baked goods like olive oil cakes or hearty muffins. Adjust your expectations for texture in more delicate items.

Coconut Oil:

• Pros:
  • Offers a distinct coconut flavor that can be desirable in certain cuisines, such as Thai or Indian dishes, and in some baked goods.
  • Contains medium-chain triglycerides (MCTs), which some studies suggest may have potential health benefits.
  • Its semi-solid state at room temperature can be useful for specific cooking techniques and in vegan recipes as a binding agent.
  • In baking, it can contribute to a tender and slightly chewy texture.
• Cons:
  • The pronounced coconut flavor can be overpowering or clash with dishes where a neutral taste is preferred.
  • It has a relatively low smoke point, making it less suitable for high-heat cooking methods like stir-frying or deep-frying.
  • In baking, the coconut flavor might not be desirable in all recipes, and it can sometimes make cakes dense if not used in the correct proportions.

Tips for Cooking with Coconut Oil:

• Consider the flavor profile: Use it intentionally when the coconut flavor will enhance the dish.
• Be mindful of heat: Opt for other oils with higher smoke points for high-heat cooking.
• Explore its texture: Its semi-solid state can be useful for no-bake desserts or as a dairy-free alternative in some recipes.
• Experiment in baking: If you enjoy the flavor, try it in cookies, muffins, or vegan desserts. Be mindful of its potential to create a denser texture.

Avocado Oil:

• Pros:
  • Boasts a mild and often neutral flavor, making it incredibly versatile for a wide range of culinary applications. It works well in everything from salad dressings and marinades to sautéing, roasting, and even grilling.
  • Rich in monounsaturated fats, similar to olive oil, which are beneficial for heart health.
  • A good source of vitamin E, an antioxidant.
  • Has a relatively high smoke point, making it suitable for medium-to-high heat cooking methods.
  • When used in baking, it can contribute to a moist and tender crumb without imparting a strong flavor.
• Cons:
  • Can be more expensive than some other commonly used cooking oils.
  • While it offers healthy fats, it may not provide the same distinct richness or mouthfeel as fats like butter or tallow in certain dishes.

Tips for Cooking with Avocado Oil:

• Take advantage of its neutral flavor: Use it when you want the taste of your ingredients to shine through.
• Utilize its high smoke point: It’s a great choice for sautéing, stir-frying, and roasting at higher temperatures.
• Consider it for dressings and sauces: Its smooth texture and mild flavor make it an excellent base.
• Experiment in baking: It’s a good option when you want a moist result without a strong oily flavor.

Tallow (Rendered Beef Fat):

• Pros:
  • Imparts a rich, savory, and satisfying flavor to many dishes. This is particularly true when used for searing meats, roasting vegetables, or making crispy fried foods. It adds a depth of umami. * see note at bottom
  • Has a high smoke point, making it excellent for high-heat cooking methods like searing, frying, and roasting without breaking down.
  • Can contribute to incredibly flaky textures in pastries and pie crusts.
  • Is a traditional fat source and can be part of ancestral or ketogenic diets.
• Cons:
  • The strong, beefy flavor is not suitable for all types of cuisine, especially dishes where a neutral or sweet flavor is desired.
  • Its solid consistency at room temperature requires melting before use and might not be as convenient as liquid oils for some applications.
  • It is not suitable for vegetarian or vegan diets.

Tips for Cooking with Tallow:

• Embrace the savory flavor: Use it to enhance the natural flavors of meats and vegetables. It’s fantastic for roasting potatoes or searing steaks.
• Utilize its high smoke point: Don’t hesitate to use it for high-heat cooking methods where other oils might degrade.
• Consider it for traditional recipes: It’s a key ingredient in many classic dishes.
• Be mindful of dietary restrictions: It’s not an option for everyone.
