蛋白质是人体重要的营养物质,蛋白质的长期缺乏会直接或间接导致人体免疫力低下、肌肉衰减、骨质疏松等病症的发生概率增加,这种现象在老年人群中更为突出,从而降低了老年人群的运动及机体代谢能力,直接影响其生活质量,这也增加了我国公共卫生及医疗系统负担,阻碍了“健康中国”战略的稳步推进。目前,对于改善老年人蛋白质摄入不足/缺乏的方式主要有改良食物特性(改变蛋白质结构)、改善身体机能(添加可促进蛋白消化酶分泌的成分)、改变饮食结构(增加寡肽的摄入)以及改变饮食习惯(增加蛋白质摄入量和种类)。本文探讨年龄增长对蛋白质消化吸收能力的影响作用,并总结现有的促进蛋白质消化吸收的方法,同时对未来改善老年人蛋白质消化吸收能力的方法进行展望,以期为促进老年人营养尤其是蛋白质吸收的研究提供参考。 相似文献

Anna Jdrusek‐Goliska Danuta Grecka Maciej Buchowski Katarzyna Wieczorowska‐Tobis Anna Gramza‐Michaowska Krystyna Szymandera‐Buszka 《Comprehensive Reviews in Food Science and Food Safety》2020,19(2):835-856
The number and proportion of older adults are increasing globally, and it is predicted that in 2020, there will be 723 million people worldwide aged 66 and older. In recent decades, numerous studies showed that healthy eating is positively associated with better nutritional status and quality of life, and the decreased incidence of noncommunicable diseases. As older adults become health conscious, the demand for foods and beverages rich in nutrients and bioactive compounds has increased. The increased demand for healthy food stimulated a recent rapid increase in designing, producing, and marketing functional foods to prevent or correct nutrient deficiencies and to improve the nutritional status of older adults. These functional products contain and/or are enriched with dietary fiber; omega‐3 polyunsaturated fatty acids; phytoestrogens; polyphenols; carotenoids such as alpha‐ and beta‐carotene; lutein and zeaxanthin; pre‐, pro‐, and synbiotics; and plant sterols and stanols. A limited number of publications have thoroughly addressed the effect of functional foods on the nutritional status of older adults. The goal of this review was to review existing recent research on the role of functional foods in healthy and active aging. 相似文献

Food-evoked emotions may provide relevant consumer insights, beyond liking alone. Previous research, using the EsSense25 method, showed that the food-evoked emotion profiles of adults vary along the two dimensions valence and arousal, whereas those as reported by seniors vary mainly in valence. However, it is unknown to what extent these findings can be replicated using other self-reported emotion measuring tools. This study therefore compared food-evoked emotion profiles of 71 younger adults (mean age 30.8 (years) ± 9.3 (SD)), 86 older normosmic adults (i.e. normal sense of smell, mean age 67.5 (years) ± 5.4 (SD)), and 70 older hyposmic adults (i.e. impaired sense of smell, mean age 68.2 (years) ± 5.9 (SD)). These groups evaluated three types of gingerbread and three types of chocolate using the self-reporting emotion measurement tools PrEmo2 tool and the Affect Grid. In line with previous observations, the self-reported emotion profiles differed between the age groups. The emotion profiles of younger adults varied for both methods along the dimensions valence and arousal, whereas, for the older groups, this valence/arousal differentiation was less clear. The effect of olfactory function was less pronounced, as the older adults with normal and impaired olfactory function had similar emotion profiles. For the PrEmo2 tool specifically, the older adults had generally lower scores for negative emotions compared to the younger adults. Hence, age should be considered an important factor when self-reported food-evoked emotions are being measured in order to develop food products targeted at specific consumer groups. 相似文献
