It has been assumed that the occurrence of gallstones is closely related to the daily diet. In this respect, we conducted two studies, the results of which appeared in two issues of the Japanese Journal of Nutrition (Vol. 28, No. 5, 1970 & Vol. 30, No. 4, 1972) since there had not been any previous detailed studies on such a relationship. We have made a further study on the relationship between the pain experienced by cholelithiasis patients and their daily diets. Ninety-one percent of the patients who were conscious of an unpleasant feeling in the stomach, gastralgia, colic pain, or backache, reported what they had consumed prior to the development of such symptoms. These included pork, Chinese-style food, fried seafoods, and excess eating or drinking. It was also found—depending on the type of the fatty acid—that there are dietetic differences in digestion, absorption, and types of pain, and also that excessive physical or mental fatigue is a factor.
The guiding principle for curing liver diseases by dietetic therapy is to provide high protein and high caloric foods to patients suffering from liver diseases. To some extent, however, it is necessary to supply such high caloric and balanced nutritious foods properly fitting the physical constitution of individual patients. Needlessly, the diet should contain high quality foods. The author has contrived a guidance method which patients well understanding these facts, can continuously follow and practice with ease. At the 20th meeting of Japan Dietetic Society, the author reported this study under the title below “Application of the Food Exchange Table to the Diet for Liver Diseases.” For one year in the past, the author practised this method of diet guidance to liver patients and studied its possible effects. Accordingly, the author proposes to make a report of this study and its effect on diet guidance. In short, patients who had faithfully followed the diet guidance indicated increase in body weights and good balance of nutrients. Moreover, symptoms of the patients were greatly improved. Consequently, the author may conclude that this method for diet guidance is effective temporarily. However, the author strongly holds the opinion that relationship dietetic therapy and results of liver function still requires study for a long period.
