Storage of descriptive data relating to food during the Showa period and analysis from the perspective of the history of food culture: Newspapers, magazines, and books

为了阐明昭和前期日本饮食信息的实际状况和饮食的变化，我们提取了1927年至1960年期间在报纸上发表的有关烹饪、食物和营养的文章，并对其内容进行了回顾。共提取了11,344篇文章（烹饪：5,618篇；食品：4,092篇；营养：1,634篇）。与1941年及更早的时期相比，1948年至1945年期间烹饪用品的数量急剧减少，但此后有增加的趋势。随着进口食品和新品种的引进，食品种类变得多样化，但在1941年至1944年期间，配给食品的数量急剧增加。营养方面的文章主要侧重于对营养知识和价值的教育，但重点逐渐转移到战时对营养的需求和营养补充剂的繁荣。昭和前半期的饮食受到战争的影响很大。

With the objective of elucidating the actual condition of dietary information and changes in diet in Japan during the first half of the Showa period, we extracted articles relating to cooking, food, and nutrition published in newspapers between 1927 and 1960 and reviewed their contents. A total of 11,344 articles (cooking: 5,618; food: 4,092; nutrition: 1,634) were extracted. The number of cooking articles decreased sharply during the 1948 up to 1945 compared to 1941 and earlier, but tended to increase thereafter. Food articles diversified with the introductions of imported foods and new varieties, but the number of articles on food rations increased sharply between 1941 and 1944. Nutrition articles focused primarily on education on the knowledge and value of nutrition, but the focus gradually shifted to the need for dietetics in wartime and the boom in nutritional supplements. Diet during the first half of the Showa period was found to be greatly influenced by the war.
