This mineral derives from the Persian word for stone, sing. Zinc has been used as material as early as the Greeks and Romans in 20 BC but was only identified as an element in 1746 by William Champion. Zinc is essential for all living creatures as it forms the active site of over 20 enzymes, the section of an enzyme that must bind with another molecule to initiate the chemical reaction. On average, we retain around 2.5g of Zinc although men require 9.5mg Zinc per day and women need 7mg. Zinc can be found in meat, shellfish, chickpeas, lentils, beans, sunflower seeds, pecans and dairy products.
This mineral naturally occurs in the soil, hence why the richest food sources of Zinc include the Brazil nut, mushrooms, garlic, brown rice and eggs. Selenium can be found in any plant grown, or animal grazed on selenite rich soil. Our body mainly stores Selenium in the skeletal muscle where 28% - 46% of our Selenium store can be found.
Iodine was discovered in 1811 by a French scientist. Bernard Courtois came across the purple substance while trying to extract other materials from seaweed, hence the name which derives from the Greek term for violet, iodes. Our bodies can't produce Iodine so we rely on dietary intake and supplementation. Fish and dairy products are rich dietary sources of Iodine, with white fish containing more Iodine than oily fish.
