Trace ElementsHypothetical Dose Response
The Good – Calcium (?) The Bad – Arsenic, Lead, Mercury and many others
Trace ElementsHypothetical Dose Response
Most “Essential” Elements

Fluorosis in China
Goiter in Sri Lanka
Similar iodine concentrations in soilBut soils in wet areas have high organic matter, which binds iodine

Hard water 'stops heart attacks'Drinking hard water may protect against heart disease, researchers have claimed.
Researchers from the Geographical Survey of Finland looked at 19,000 men who had suffered heart attacks. They found for every unit increase in water hardness, there was a 1% decrease in the risk of having a further attack. Writing in the Journal of Epidemiology and Community Health, the researchers said the findings explained regional variations in heart attack rates.
