Agricultural practices affect arthritis

Newnham RE · Nutrition and Health

The origin of the boron-and-arthritis claim, and effectively its whole evidence base: regions with boron-poor soils were reported to have higher arthritis rates than boron-rich ones. Everything asserted about boron and joints since traces back to this line of argument.

Population

Ecological comparison of regional arthritis rates against soil and dietary boron

Intervention

Higher environmental and dietary boron

Comparator

Boron-poor regions

Limitations

An ecological argument in a journal without a substantial peer-review record, comparing regions that differ in far more than soil boron — diet, income, occupation, latitude and diagnostic practice among them. No individual-level exposure and no individual-level outcome. Recorded so that the claim's actual source is visible rather than inferred.
