The purpose of this study was to evaluate the nutritional adequacy of senior-friendly foods sold in Korea, focusing on protein and sodium. This study examined the nutritional content of 170 products with nutritional labels that were sold in online stores in Korea and categorized the products into 93 staple foods (cooked rice, porridge, and mousse) and 77 side-dish and snack foods (braized·steam·roast products, broth, sauces, and snacks). Then, the adequacy of the nutritional content of these foods, focusing on protein and sodium, was evaluated according to product type. The 93 staple products and 77 side-dish products had average serving sizes of 163.27 g and 127.92 g, prices of $3.25 and $2.72, and energy contents of 295.25 kcal and 141.95 kcal, respectively. For staple foods, the energy content was significantly greater in cooked rice, but the protein content and index of nutrition quality (INQ) were significantly greater in mousse. There were no significant differences in sodium content or contribution to adequate intake (AI) by product type, but the sodium INQ was significantly greater in the mousse and porridge. For side-dish foods and snack products, the protein content, contribution to the recommended intake, and INQ were all significantly greater for the braized·steam·roast products. Sauces and braized·steam·roast products were significantly higher in sodium content and contribution to the AI, while broth was significantly higher in sodium INQ. These findings can be used to guide proper product selection and nutritional management that considers the health characteristics of health-vulnerable and elderly people.

All of us have no time to predict and prepare for a rapidly-approaching future change in the 21st century, thereby being reality that we feel uneasy about future society. Accordingly, there is necessity for re-consolidating environment and daily culture in preparation for future society, namely, aging society. Given well preparing for super-aging society that will approach in the future, by which this effort becomes what bad luck often brings good luck, our country's role is thought to get probably bigger even in the globally silver industrial market in near future. We need to synthetically recognize a human being's aging psychological and physical conditions through the aging experience exhibition available for publicizing properly this historical phenomenon, and to pay more attention to importance of interaction between a human being and product environment. The experience exhibition is a concept for the exhibition form and the spatial composition, which emphasized interaction, with having escaped from the simply exhibition space. Given trying to communicate information more scientifically with escaping from the conventional exhibition of seeing and listening, it is also important to research Into the basis for exhibition as the experience space based on interaction. After all, a human being's aging is the unavoidably future phenomenon. And, importance of environment, which influences a human being, is very mutual as well. Our country is desired to develop a research on interaction of the exhibition experience space available for broadening recognition of senior-friendly and for properly experiencing this, thereby being an opportunity that the business entity, which plans silver industry, and the academic circles, which research and develop this, do mutually cooperate and can make silver industry grow further.
