In Japan, kombu (Laminaria japonica), a type of seaweed, has been consumed for centuries. It contains a variety of active compounds such as minerals, vitamins, and dietary fiber. The aim of this human pilot study is to investigate the effects of kombu on lifestyle-related diseases. The study had a randomized crossover design, and the subjects (N=48) freely took 6 g of roasted kombu a day for 4 weeks. The subjects' responses to the Gastrointestinal Symptom Rating Scale questionnaire suggested that the frequent intake of kombu may lead to the relief of constipation, diarrhea, and hard stools. In addition, blood tests indicated the possibility that the frequent intake of kombu can decrease the serum triglyceride levels of subjects with abnormally high serum triglyceride levels. Kombu intake might lead to relief from intestinal ailments and improvements in hypertriglyceridemia.
