Abstract
Manganese, copper and zinc contents of 87 Japanese foods were determined and the data were tabulated.
Cereals, nuts, beans, mushrooms and seaweeds were generally rich in manganese, the highest value of 7.00mg% was found with dried Juda's ear (Auricularia auricula-judae, Schroet). Copper was contained universally but poorly in almost all foods examined, the highest being 3.41mg% in dried brewer's yeast. Meats, milk and its products, cereals and beans contained much zinc. The highest content found 8.80mg% in beef liver.
