The Dangers of Seed Oils for Health and Why Animal Fats Are Better

Understanding Seed Oils and Their Risks

Seed oils, such as canola, sunflower, soybean, corn, and safflower, are widely used in processed foods and restaurant cooking. They are typically high in omega-6 polyunsaturated fatty acids, especially linoleic acid. Some research suggests that when linoleic acid is heated or consumed in excess, it can break down into pro-inflammatory compounds. Chronic inflammation has been linked to an increased risk of diseases like diabetes, depression, cardiovascular disease, and cancer.

Seed oils are often extracted through chemical processes, which may introduce unwanted residues and further degrade the oil’s quality. Critics argue that the high omega-6 content and chemical processing can contribute to inflammation and other health problems, especially when seed oils are a major part of the diet.

Why Animal Fats May Be a Healthier Choice

Animal fats—such as butter, lard, and tallow—have been used in traditional cooking for centuries. They tend to have a more balanced ratio of omega-3 to omega-6 fatty acids, which may help reduce inflammation and promote heart health4. Animal fats are also rich in fat-soluble vitamins like A, D, E, and K, which are essential for immune function, bone health, and hormone regulation4.

Another advantage is the higher smoke point of many animal fats, making them more stable during cooking and less likely to break down into harmful compounds compared to some seed oils4. While animal fats are higher in saturated fat, recent research has challenged the idea that saturated fat is solely responsible for heart disease. Moderation and variety in fat sources remain important, but animal fats can be part of a balanced diet

Conclusion

While seed oils are common and convenient, concerns about their inflammatory potential and processing methods have led many to prefer animal fats for cooking and nutrition. Animal fats offer a more balanced fatty acid profile, essential vitamins, and greater stability at high temperatures. As with all dietary choices, moderation and individual tolerance are key—especially for those with allergies or sensitivities to seed oils.
