Seed Oils

Seed oils (also called vegetable oils) like soybean, corn, sunflower, and canola oil are highly processed oils extracted from seeds using heat and chemical solvents. They're rich in omega-6 polyunsaturated fats that oxidize easily when heated, potentially creating inflammatory compounds. These oils have only existed in our food supply for about 100 years, yet now make up a huge portion of calories in modern diets—especially in processed foods and restaurant meals. Many researchers question whether this dramatic shift away from traditional fats is contributing to chronic inflammation and metabolic disease.
