MIND-NL diet adherence moderates the relation of low-grade systemic inflammation with neuroinflammatory metabolites and cognitive functioning: an exploratory cross-sectional study in older adults.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundObservational studies have linked high adherence to the “Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay” (MIND) diet to improved cognitive functions in older adults. The underlying peripheral and central mechanisms of this association remain poorly understood, although multiple nutrients in the MIND diet are known for their anti-inflammatory effects. Therefore, we explored the cross-sectional relation between MIND diet adherence (Dutch version), systemic inflammation, neuroinflammation, and cognitive functioning in older adults. In addition, we examined the role of intestinal barrier permeability in MIND diet associations with (neuro)inflammation.
methodsWe included 88 older adults (60–75 year) at risk of cognitive decline. MIND-NL diet adherence was assessed using a food frequency questionnaire. Systemic inflammation (C-reactive protein levels, white blood cell-counts and neutrophil-to-lymphocyte ratio) and intestinal barrier permeability (lipopolysaccharide-binding protein, zonulin, and lipopolysaccharide) markers were measured in blood. Neuroinflammation-associated metabolites (myo-inositol, choline and creatine) were measured in the dorsolateral prefrontal cortex with proton magnetic resonance spectroscopy (1H-MRS). Cognitive functioning was assessed with a neuropsychological test battery.
resultsLinear models showed that both MIND diet adherence and systemic inflammation did not predict neuroinflammation or cognition independently. However, MIND diet adherence significantly moderated the relation between systemic inflammation and neuroinflammation (β=-0.22, p = 0.04) as well as between systemic inflammation and cognition (β = 0.22, p = 0.02). Specifically, in individuals with lower MIND diet adherence (identified as scores ≤ 7), systemic inflammation was positively related to neuroinflammation, and negatively to cognition. Similarly, MIND diet adherence significantly moderated the relation between intestinal barrier permeability and neuroinflammation (β=-0.28, p = 0.05). Finally, within participants with lower MIND diet adherence (median split at ≤ 8.75), systemic inflammation mediated the relation between the intestinal barrier permeability and neuroinflammation (path coefficient = 0.427 [0.072; 0.891], p = 0.04).
conclusionOur findings show that MIND diet adherence modulates inflammation-brain relationships in aging, with detrimental associations between systemic inflammation and both neuroinflammation and cognitive functioning observed only in individuals with lower adherence. Moreover, MIND diet adherence similarly modulates the systemic inflammation-mediated relationship between intestinal barrier permeability and neuroinflammation. These findings should be confirmed in randomized controlled trials.
