Good fats is favourite topic of mine, it massively contributes to our health.
Why good fats you might ask?
Good fats nourish our insides, make our skin and eyes clear and healthy and don't convert to cholesterol or go awry in our systems to later cause cancer and immunity issues.
It is as simple as this, if you are frying you need oils that will not burn for eg coconut oil, peanut oil and sunflower, (vegetable oils)
Cold pressed Oils are meant to be used exactly as that states 'cold pressed' after you have finished the cooking process.
