    A review is presented of the recent results mainly obtained by author's studies on the texture, taste and odor of chicken, pork and beef. An organoleptic study revealed that the texture of beef was very similar to that of pork but quite different from that of chicken. The meat-like taste and umami of soup were most intensive with chicken and weakest with beef, the umami of the soup being attributable to glutamic acid and 5'-inosine monophosphate. The organoleptic test panel was unable to identify chicken, pork and beef soups by their tastes, possibly due to the fact that the free amino acid pattern of each soup was similar with these three types of meat. On the other hand, the organoleptic test panel could readily identify chicken, pork and beef by their odor. The meat of Nagoya Cochin chicken was shown to have a unique odor of the meat of aigamo (a crossbreed of domestic and wild ducks). There was no difference in the odor character among the meat from three types of pig, including Kagoshima Berkshire. Wagyu beef from Japanese Black Cattle was found to have a preferable aroma (Wagyu beef aroma) which was sweet and fatty. This Wagyu beef aroma was concluded to be the main reason why the Japanese prefer Wagyu beef to imported beef. The Wagyu beef aroma was generated through unknown reactions between lean meat, fat and oxygen and the subsequent heating process.

    The purpose of this study was to examine appropriate measures of knowledge, attitudes, and behavior for assessment/evaluation for nutrition education for young adults. The conceptual framework was developed based on two models: one is the Precede-Proceed model by Green and the other is the framework of nutrition ecology by Adachi. Firstly, based on the review of the recent studies and 16 focus group interviews for young adults conducted at worksite and community, several measures were selected; such as self-efficacy, stage of change, and the scale for positive dietary behavior and attitude developed by the author. Secondly, a cross-sectional survey was conducted with questionnaires including those measures, for 397 young adults at 3 worksites. The correlations among health, nutritional status and those measures were examined. Thirdly, participatory nutrition education intervention was implemented at 2 worksites in order to examine the appropriate measures for evaluation of the participants' changes of attitudes and behaviors. Finally, worksite health professionals and dietitians examined the selected measures, from the viewpoints of those applications into worksite health and nutrition promotion. Conclusively, self-efficacy, dietary stage of change, and dietary skill were suggested to be appropriate and valid measures for assessment and evaluation for nutrition education for young adults.

    The effects of administering a dietary fiber (DF) beverage on defecation and intestinal flora were studied in female college students prone to functional constipation (n=10). The DF beverage (125ml) contained 3g of commercial depolymerized sodium alginate as a non-fermentable dietary fiber and 3g of commercial water-soluble corn bran fiber as a fermentable supplement. The fecal weight was increased (p<0.05) after 2 weeks of administration, suggesting that DF was effective against constipation.
    The DF beverage resulted in significantly higher (p<0.05) numbers of total microbes, anaerobes, fecal bacteroides and bifidobacterium than those from a placebo during the administration period. The ratio of bifidobacterium to the total number of microbes was also increased by about 40% (p=0.10) at the end of administration. The fecal short chain fatty acid (SCFA) and ammonia contents per weight of wet feces was unchanged by the administration, so the intestinal environment is presumed not to have been adversely affected.
    These results indicate that the administration of the DF beverage improved both the intestinal environment and intestinal flora.

    栄養疫学研究に役立てることを目的として, 20歳女子の食事によるタウリン摂取量と食品群別摂取量の関連より, 魚介類及びレバー摂取量を用いたタウリン摂取量の推定式の開発を試みた。さらに, タウリン摂取量の季節変動や日常の食事中タウリンの1日摂取量を求めるために必要な食事調査日数, 推定式の交差妥当性についても検討を行い, 以下の結論を得た。
    1) 食事によるタウリン摂取量を従属変数とし, その他の食品群別摂取量 (動物性食品及び海藻類) を独立変数とする重回帰分析の結果, 82%が説明され, タウリン摂取量と魚介類摂取量の間には, 標準偏回帰係数0.60(p<0.001), レバー摂取量との間には, 0.52(p<0.001)で有意な関連が認められたが, その他の食品群については, 関連が認められなかった。
    2) 食事によるタウリン摂取量を従属変数, 1日の魚介類別 (6分類) 摂取量及びレバー摂取量を独立変数とし, 夏 (6~7月) と冬 (12~1月) の食事調査結果をそれぞれについて重回帰分析し, 比較した結果, 夏と冬のいずれにおいてもタウリン摂取量と魚類摂取量, いか・たこ類摂取量の間に関連が認められたが, タウリン摂取量と貝類及びえび・かに類との間には, 冬においてのみ, レバー摂取量については, 夏においてのみ関連が認められた。
    3) 日常の食事中タウリンの1日摂取量を算出するのに必要な食事調査日数は, 10%以下の誤差範囲で704日, 20%以下で176日であった。
    4) 夏と冬の食事調査結果をもとに算出した1日の食事中タウリン摂取量を従属変数, 1日の魚介類及びレバー摂取量又は魚介類別及びレバー摂取量を独立変数として重回帰分析を行い, タウリン摂取量の推定式を検討した結果,“タウリン摂取量(mg/day)=1.909×魚類摂取量(g/day)+6.798×貝類摂取量(g/day)+2.867×その他魚介類摂取量(g/day)+22.95×レバー摂取量(g/day)+14.02”となった (決定係数が73.5%)。
    以上, 魚類摂取量, 貝類摂取量, その他魚介類摂取量(えび・かに類, いか・たこ類, その他) 及びレバー摂取量から, タウリン摂取量の推定式は, 他の地域の対象者での交差妥当性の検討からも, 20~21歳女子学生において, タウリン摂取量推定の精度, 妥当性も高いものを得ることができた。また, 日常の食事中タウリンの1日摂取量を求めるには, 10%以下の誤差範囲で704日, 20%以下の誤差範囲で176日以上の食事調査をもとに算出する必要性が示唆された。今後, さらに幅広い年齢層や男性においても活用できる食事中タウリン摂取量の推定式の検討を考えている。
