为了能够验证对营养建议的依从性,评估老年受试者的食物摄入量至关重要。在这种情况下,估计特定膳食生物活性物质的摄入量,如多酚,尽管特别具有挑战性,有必要计划可能的干预策略来增加他们的摄入量。本研究的目的是:(i)评估在住宅护理环境中提供的饮食菜单的营养成分;(ii)估计参与MaPLE研究的一组老年受试者中营养素和多酚的实际摄入量;(iii)调查八周富含多酚的饮食模式的影响,与八周的控制饮食相比,老年参与者的总体营养素和多酚摄入量。提供给参与者的菜单平均每天提供约770mg的总多酚,季节之间的变化很小。对实际消费的分析,使用称重的食物日记测量,与菜单提供的相比,显示出更低的营养素(〜20%)和多酚摄入量(〜15%)。讨论了饮食模式的可行性,该模式可以增加多酚的摄入量,并对与年龄相关的疾病具有公认的健康益处。从制定目标人群的饮食指南的角度来看。
The evaluation of food intake in older subjects is crucial in order to be able to verify adherence to nutritional recommendations. In this context, estimation of the intake of specific dietary bioactives, such as
polyphenols, although particularly challenging, is necessary to plan possible intervention strategies to increase their intake. The aims of the present study were to: (i) evaluate the nutritional composition of dietary menus provided in a residential care setting; (ii) estimate the actual intake of nutrients and
polyphenols in a group of older subjects participating in the MaPLE study; and (iii) investigate the impact of an eight-week polyphenol-rich dietary pattern, compared to an eight-week control diet, on overall nutrient and polyphenol intake in older participants. The menus served to the participants provided ~770 mg per day of total
polyphenols on average with small variations between seasons. The analysis of real consumption, measured using weighed food diaries, demonstrated a lower nutrient (~20%) and polyphenol intake (~15%) compared to that provided by the menus. The feasibility of dietary patterns that enable an increase in polyphenol intake with putative health benefits for age-related conditions is discussed, with a perspective to developing dietary
guidelines for this target population.
