Algin in the diet, as from kelp (seaweed) or the supplement sodium alginate, helps to bind lead and other heavy metals in the gastrointestinal tract and carry them to elimination. Pectin and other fiber foods in the diet will also tend to bind the heavier metals and reduce absorption. With this, though, we need to take more of our essential vitamins and minerals, such as the Bs, vitamin C, iron, calcium, zinc, copper, and chromium, to help decrease lead absorption. As mentioned, L-cysteine, 250 mg. twice daily, is a sulfur-containing, detoxifying amino acid that will help bind and eliminate lead.
Children can be somewhat protected by getting adequate iron, calcium, and vitamins C and E in their diet and as supplements in appropriate amounts for their age. This program may also help get a little of that lead out and keep them clear thinking, more balanced, and active (but not hyperactive).
Our understanding of lead is just beginning. Better prevention and treatments for lead intoxication, along with reduced lead use by industry in fuels, cars, paints, and so on, should enable us to control the problems associated with this widespread contaminant.
