Detaljert beskrivelse
Obesity is a significant risk factor for the development of cognitive impairment, making precise nutritional interventions a vital strategy for preventing and managing this condition. Based on an established cohort, this randomized controlled trial aims to evaluate the efficacy of substituting regular dietary oil with functional diacylglycerol (DAG) oil in obese patients with MCI.
The study will analyze changes in overall cognitive function, body composition, and dietary quality before and after the 6-month intervention. Furthermore, the study will explore the underlying mechanisms by analyzing biological samples (blood and feces) for alterations in lipid metabolites, gut microbiota composition, inflammatory cytokines, and specific markers of white adipose tissue browning. The findings will help determine the therapeutic potential of DAG oil in regulating lipid metabolism and delaying cognitive decline.

Beskrivelse
Inclusion Criteria:
- Meets the diagnostic criteria for obesity combined with mild cognitive impairment (MCI) (obesity: BMI ≥28.0 kg/m^2 per the 2022 Chinese Expert Consensus on Obesity Prevention and Treatment; MCI: Montreal Cognitive Assessment [MoCA] score below the education-adjusted cutoff, confirmed by a neurologist)
- Aged 45 to 75 years
- Has not been on a diet or has discontinued dieting for at least 3 months, and has not taken fish oil or similar supplements, or is willing to discontinue such supplements for 3 months prior to the intervention
- Able to accept and consume DAG oil as part of daily diet
- Voluntarily agrees to participate and signs the informed consent form
Exclusion Criteria:
- History of neuropsychiatric disorders such as stroke, epilepsy, or schizophrenia
- Cognitive impairment attributable to depression, thyroid disease, traumatic brain injury, or drug- or alcohol-induced intoxication
- History of cerebrovascular disease, or cognitive decline due to severe impairment of cardiac, hepatic, pulmonary, or renal function
- Use of antibiotics, health products, or nutritional supplements within 2 weeks prior to fecal sample collection; or gastrointestinal symptoms (trauma, inflammation/infection, abdominal pain, diarrhea, or constipation) or vaccination history within the same period

Placebo komparator: RSO Group (Rapeseed Oil)
Participants with obesity and mild cognitive impairment (MCI) will be provided with conventional rapeseed oil (RSO), in which diacylglycerol (DAG) occurs only at the low level naturally present in regular cooking oil (predominantly triacylglycerol), for household use for 6 months.
Dietary guidance based on balanced nutrition principles will be provided.
Compliance, dietary intake, anthropometric, biochemical, and cognitive assessments will be evaluated at baseline and 6 months.
|
A commercially available conventional rapeseed oil for daily household cooking use, containing diacylglycerol (DAG) only at the trace level naturally occurring in regular vegetable oil.

Eksperimentell: DAG Group (Diacylglycerol Oil)
Participants with obesity and MCI will be provided with rapeseed oil-based diacylglycerol (DAG) oil (DAG content ≥40%), produced from conventional rapeseed oil via lipase-catalyzed enzymatic conversion followed by distillation, deodorization, and decolorization, for household use for 6 months, replacing conventional cooking oil.
Dietary guidance based on balanced nutrition principles will be provided.
Compliance, dietary intake, anthropometric, biochemical, and cognitive assessments will be evaluated at baseline and 6 months.
|
A rapeseed oil-based functional oil produced via lipase-catalyzed enzymatic conversion, with a diacylglycerol content ≥40% (national standard requirement), for daily household cooking use in place of conventional cooking oil.
