Zinc is an essential trace element, 22 Jun 2010
This review is from: The Zinc Solution (Hardcover)
Zinc is an essential trace element in human nutrition - you don't need huge amounts, but you need some. This is a fairly recent discovery - I've seen a British WW2 manual for housewives telling them that galvanised iron vessels (galvanised = covered with a coating of zinc, to prevent rust) could lead to 'zinc poisoning' which is true but off-putting. It seems rather odd that a book on this subject should have been published by a publisher specialising in alternative, new age-style books. Prof Bryce-Smith was/is a chemist best known for opposing lead tetraethyl in petrol, though he's not a biochemist. He ought to be known for getting the subject of trace element nutrition taught to medical students - when he started, they had just one hour on the subject in their seven-year course! This book must have helped push interests in nutrition into the middle-class mainstream, though of course many supposed experts were antagonistic, considering that ordinary food contains sufficient micro-nutrients. It has a test for zinc deficiency (can you taste zinc sulphate in water?), and says deficiency is linked with anorexia, schizophrenia, wound-healing, vision problems, infertility, and other hard-to-treat conditions. Much of this material seems to be mainstream now. One of the interests of this book is the resistance of psychologists to the idea that a simple cure can be had with a simple supplement. They'd prefer to get paid for something that goes on indefinitiely.
