研究目的:

探究符合中国饮食习惯的抗炎膳食干预对轻度认知障碍者认知功能的改善作用;明确肠道菌群及其代谢产物在抗炎膳食改善认知功能中的作用机制,构建“抗炎膳食→肠道菌群及代谢产物→认知功能”的作用途径,进而为痴呆症干预提供新靶点和新思路。  

Objectives of Study:

To investigate the efficacy of an anti-inflammatory dietary intervention tailored to Chinese dietary habits in improving cognitive function in individuals with mild cognitive impairment; to elucidate the mechanism by which the gut microbiota and its metabolites mediate the cognitive benefits of the anti-inflammatory diet, thereby establishing the pathway of "anti-inflammatory diet → gut microbiota and metabolites → cognitive function" and providing novel targets and insights for dementia intervention.

干预措施:

在入组后接受痴呆防控知识健康教育。试验期间,注册营养师仅对受试者提供健康膳食教育,不对膳食进行纠正。

Intervention:

After enrollment, participants will receive health education on dementia prevention. During the trial, registered dietitians will provide only healthful dietary education to the participants without actively correcting their dietary intake.

Group:

Anti-inflammatory diet group

Sample size:

干预措施:

基于受试者基线自报的膳食模式,由本单位2名注册营养师制定个性化抗炎膳食方案。基本原则是减少原有促炎食物的摄入,增加原有抗炎食物的摄入,同类食物中抗炎替代促炎食物。在增加膳食抗炎潜力同时,最大程度保留受试者原有饮食习惯,以提高依从性。推荐使用蒸、煮、炖等烹饪方法,不推荐油炸或高温烹饪过度。干预期间(12个月),通过手机智能软件,每月推送受试者个性化的抗炎食谱。

干预措施代码:

Intervention:

Based on participants' self-reported dietary patterns at baseline, two registered dietitians from our institution will develop individualized anti-inflammatory dietary plans. The core principle is to reduce the intake of pro-inflammatory foods while increasing the intake of anti-inflammatory foods, replacing pro-inflammatory foods with anti-inflammatory alternatives within the same food category. To enhance adherence, the intervention aims to maximize the preservation of participants' original dietary habits while increasing the anti-inflammatory potential of the diet. Cooking methods such as steaming, boiling, and stewing are recommended, whereas deep-frying or high-temperature cooking is discouraged. During the 12-month intervention period, personalized anti-inflammatory meal plans will be delivered monthly to participants via a mobile intelligent application.

盲法:

由于干预组和对照组间干预措施不一样,无法实现三盲。在试验开展的过程中,会减少两组间受试者的接触,另外,数据处理和分析人员对分组情况不知晓

Blinding:

Due to the differences in interventions between the intervention group and the control group, triple-blinding could not be achieved. During the trial, contact between participants in the two groups will be minimized. Additionally, the personnel responsible for data processing and analysis will remain blinded to group allocation.
