Mercury, Lead, Arsenic, Cadmium: "Heavy Metals" to Know

In the industrial world in which we live we can run but we cannot hide from all toxins that can rob us of our health and vitality. However, armed with adequate scientific information, we can avoid many toxins and strive for optimal health. A group of health stealers are the heavy metal toxins. These include the big four of mercury, lead, arsenic and cadmium.  These metal compounds are found in the earth’s crust but play no role in human health. Indeed, they have been associated with a range of illnesses in children and adults including cardiovascular disease (

We can now add toxic heavy metals to the list of environmental pollutants to avoid so that your bodies can perform the miracle of self-healing and maximal performance so you feel good every day. While there is no controversy over the recommendation to never smoke, perhaps it is no longer wise to teach a man to fish along with cooking bone broth or rice.
