The Value of the Oyster in Nutritional Anemia

The Role of Copper in the Setting, Metamorphosis, and Distribution of the American Oyster, Ostrea virginica

“…Oysters contain more copper per unit of weight than any other animal which renders them particularly valuable in our diet. Recent studies by Levine, Remington, and Culp ( 1931) show that oysters contain considerable amounts of copper, iron, and manganese and that these elements are responsible for the antianemic potency of this seafood.…”

The oyster—Modern science comes to the support of an ancient food

“…Their work was corroborated by the investigational findings of Levine and Remington (26) in South Carolina who employed local oysters in feeding white rats likewise made anemic on the milk diet. These latter results inspired editorial comment in the Journal of the American Medical Association (December 20, 1931) under the heading: "Oysters-A Pleasant Form of Therapy.…”

The Copper Content of Sea-water

“…It remains to consider the presence of iron in sea-water as a source of error in direct examination. According to Ansbacher, Remington and Culp (1931) with the xanthate method, 0-050 mg. of iron gives the same colour as 0-0123 of copper. On testing the carbamate method, however, the writer found that it required a concentration of 1-32 mg. per litre of ferric iron to give as much colour as 0-01 mg. per litre of copper.…”

“…Inrecent years the study of the distribution of copper has become of increasing importance in connection with researches on its nutritional value. Analyses have been given of the copper content of many vegetables and fruits (Remington and Shiver, 1930) and of the oyster in relation to the cure of nutritional amBmia (Levine, Remington and Culp, 1931). Orton (1924) collected a number of results bearing on the copper content of oysters.…”
