Butter
I am an avid fan of butter! I believe that it's one of the very best things to fry in, as it doesn't turn toxic the way oils do when they get hot. They are also filled with loads of natural vitamins and minerals.
Some of the things butter helps you out with is: Helps protect your thyroid, helps to treat against internal fungal infections like candida, butter contains antioxidents, are anti-cancer and anti-tumor, is an immunity booster, helps you to absorb calcium, protects against tooth decay, protects your joints, and the list just goes on and on!
So don't be afraid to use butter! It's good stuff!
