Most all chocolate has heavy metals like cadmium and lead in it because of where the trees are grown. Cadmium is much worse than lead and by detoxing we can eliminate most of the heavy medals from our body. Ghiradelli is the only chocolate I found without Cadmium, although it does still have some lead in it. In order not to give up chocolate entirely, I order Ghiardelli. But, I also regularly detox so as to eliminate mercury from Omega fish oils. and chocolate. Unfortunately, there is cadmium, lead, mercury, and other heavy metals n most of the soil that our food is grown in, especially root veggies. So it is important to detox in order to live a healthy life without toxic poisons.
