THYROID
LOW SELENIUM STATUS AND THYROID STIMULATION
Selenium is essential for the production and regulation
of thyroid hormones. A study was designed to investigate
thyroid function across large variations in dietary selenium
intakes and correlate this with blood levels of selenium
and thyroid health. 68 healthy men, previously screened
for endocrine disease, selenium supplements and food frequency
data, gave blood for analysis of plasma selenium and thyroid
hormones.
Results revealed that plasma selenium was positively and
significantly correlated with the number of fish meals per
month. Thyroid-stimulating hormone (TSH) was negatively
and significantly correlated with plasma selenium levels.
This suggests that low selenium status causes a homoeostatic
increase in TSH.
