What Are Seed Oils?
Seed oils are plant-based oils extracted from seeds like soybean, sunflower, corn, and canola. Due to their affordability and long shelf life, they are a go-to choice for manufacturers and fast-food chains. Commonly labeled as "vegetable oil," they often seem like a healthy option—but their production and nutritional profile tell a different story.
Why Are Seed Oils Unhealthy?
Seed oils are high in omega-6 fatty acids, which, when consumed excessively, can disrupt the balance of omega-3 and omega-6 in the body. This imbalance can lead to:
- Chronic inflammation: A key factor in diseases like heart disease, arthritis, and diabetes.
- Oxidative stress: Seed oils are highly processed, often undergoing chemical extraction and high-heat treatments that generate harmful free radicals.
- Hormonal disruption: Studies link seed oils to disrupted hormonal balance and weight gain.
- Increased risk of chronic diseases: Diets high in seed oils have been associated with obesity, metabolic disorders, and cardiovascular issues.
