10. Vegetable oils
I always do a double take whenever I see a bottle of canola, corn, soy or sunflower oil sitting in someone’s kitchen pantry. That’s because vegetable oils are one of the most harmful foods on the planet. These oils are processed to a point where they’re almost inedible, they contain an atrocious omega-3 to omega-6 ratio, and they expose your body to free-radical supporting oxidized cholesterol. Stay away from the vegetable oils and stick to staples like butter, coconut oil or avocado oil.
