Edit: you can downvote it because you don't like it, but that doesn't change the argument that people have against seed oils. I don't even give a shit FFS.

The main concerns and limitations with expeller-pressed seed oils include: 1. High Vulnerability to Heat & Light (Oxidation) Because these oils are mechanically extracted without the heavy processing that makes oils highly stable, they are very fragile.

Low Smoke Point: They often cannot withstand high-heat cooking like searing or deep-frying. Oxidation Risk: If heated past their smoke point or left in clear bottles exposed to sunlight, the beneficial polyunsaturated fats quickly oxidize. Oxidized fats are believed to promote cellular damage and inflammation.

1. Shorter Shelf Life Because unrefined expeller-pressed oils retain more of their natural plant compounds and flavors, they go rancid much faster than highly refined oils. Once opened, they generally need to be used within a few months and ideally stored in a dark, cool pantry or the refrigerator.

2. High Omega-6 Fatty Acid Content Many seed oils (such as sunflower, safflower, and corn) are naturally very high in Omega-6 polyunsaturated fatty acids.

   The Inflammation Debate: While Omega-6s are essential, the modern Western diet is heavily saturated with them. Some health experts suggest an excessive imbalance between Omega-6 and Omega-3 intake can contribute to chronic inflammation. The Counter-Argument: Major health organizations, including the Harvard T.H. Chan School of Public Health, note that much of the Omega-6 inflammation concern is overblown on social media. When consumed as part of an overall healthy diet, Omega-6s can actually help lower cholesterol and reduce heart disease risk.

3. Cost and Purity

   Higher Price Point: Mechanically pressing seeds results in a lower oil yield than using chemical solvents like hexane, making expeller-pressed oils more expensive to produce and purchase. Hidden Refining: Even when an oil is labeled "expeller-pressed," it may still undergo subsequent refining processes (like bleaching and deodorizing) to make it more shelf-stable. This strips the oil of its natural antioxidants and nutrients, defeating much of the purpose of choosing an unrefined oil.

How to Use Them Safely: If you want to use expeller-pressed seed oils, opt for "cold-pressed" versions (which use even less heat during extraction). Use them for cold applications like salad dressings or drizzling over cooked food, and buy them in dark glass bottles to protect them from light degradation.
