By G. L. Seifert and H. C. Wood
Summary: As read at the Second International Seaweed Symposium in 1956. Seifert reports on a study in which "the nutritional value of sea kelp and trace minerals was demonstrated." In the experiment, the diet of 400 pregnant women—the majority suffering anemia—was fortified with tablets of dried giant bladder kelp (Macrocystis pyrifera). In the majority of the subjects, the anemia disappeared within six to eight weeks of the onset of supplementation. In addition, there was "a spectacular drop in the incidence of colds" among the subjects. (Anemia and a tendency to develop colds is a common problem faced by pregnant women, the investigators note.) Seifert adds that the success of the study is likely a result of the high trace mineral content of the kelp, concluding that "in certain types of body stress, the difference between health and disease may often be a trace mineral supplement."
