The Australian and New Zealand Vitamin Decoder, Australia, 1991-1995

The Australian and New Zealand Vitamin Decoder by Dr Kate Short; tabulating device giving information on values, toxicity and RDI, published in Melbourne, Australia, 1991-1995.

Vitamins and minerals cannot be made by the body so have to be included as part of a healthy and balanced diet. A series of coloured wheels gives information on eighteen different vitamins and minerals, their natural sources, functions, recommended daily allowance (RDA) and the effects of exceeding this limit. For instance, folic acid is found in leafy green vegetables and liver and is recommended for pregnant women to help prevent spina bifida and malformations of the foetus. The decoder could be purchased in health stores.
