Unlearn
Unfortunately for the last 100+ years the medical industry has been financed and indoctrinated by pharmacological vested interests so you need to become educated in the area to make accurately informed decisions with regards to your own health and well being.
Without wanting to blow my own trunpet, my book is a great place to start as it covers a wider range of topics than do most and I admit my bias up front: it is towards you being in control of your decisions, your choices and your outcomes, preferably without toxins and with food and vitamin and mineral supplements – what the body needs to be fully nourished and disease free.
