THE THYROID CONTAINS THE HIGHEST CONCENTRATION OF SELENIUM IN THE HUMAN BODY and is able to retain it even under conditions of severe deficiency.
Selenium deficiency has been associated with a number
of adverse thyroid conditions, including hypothyroidism,
subclinical hypothyroidism, enlarged thyroid, thyroid cancer and autoimmune thyroid disease, including Hashimoto's disease and Grave's disease.
Selenium intake is very different from one part of the world to another because of the differences in the SELENIUM CONTENT OF THE SOIL on which crops and animal food are grown.
Selenium that people consume ranges from deficient (7 µg/d) to toxic (4990 µg/d) according to studies.
Although BRAZIL NUTS are the richest selenium food source they cannot be recommended as
the main source as the content is VERY VARIABLE, ranging
from 0·03 to 512 mg/kg fresh weight, and they are high
in BARIUM, which can be TOXIC.
ORGAN MEATS and SEAFOOD are the best sources, followed by muscle meats, cereals and grains, although the selenium content of the latter varies widely with location, being towards or at the bottom of the range in the UK and Europe but at the top in North America, most notably in Canada.
In China, selenium-enriched tea is an option to top up your selenium levels.
Given the sources described, vegans and vegetarians in the West are particularly at risk of inadequate selenium intake.
