Dietary patterns in people with mild cognitive impairment

Area of Science:

• Nutritional Neuroscience
• Gerontology
• Cognitive Health

Background:

• Dietary habits significantly influence cognitive function and may modulate diet-related cognitive decline.
• Identifying specific dietary patterns associated with cognitive impairment can inform prevention and treatment strategies.
• Maintaining cognitive health is crucial for quality of life, especially in aging populations.

Purpose of the Study:

• To characterize the dietary habits of individuals diagnosed with mild cognitive impairment (MCI).
• To identify differences in food consumption patterns between individuals with and without MCI.
• To explore potential dietary interventions for managing and preventing cognitive decline.

Main Methods:

• A survey was conducted involving 146 participants, with 101 diagnosed with MCI and 45 in a control group (n-MCI).
• Dietary habits were assessed using the Questionnaires Eating Behaviour (QEB).
• Cognitive function was evaluated using the Montreal Cognitive Assessment (MoCA) screening test, with MCI diagnosis based on a score of 25 or fewer points.

Main Results:

• Significant differences were observed in breakfast and lunch food consumption between MCI and n-MCI groups.
• MCI patients consumed significantly less low-fat dairy (p=0.001), vegetables (p=0.034), cereal products (p=0.001), and fish (p=0.007).
• Conversely, the MCI group exhibited higher consumption of high-fat and high-sugar products (p=0.010).

Conclusions:

• Dietary patterns low in saturated fats but rich in omega-3 polyunsaturated fatty acids, vitamins, and bioactive substances may aid in MCI prevention.
• Health-conscious dietary behaviors, exemplified by the Nordic Diet or Mediterranean Diet (MD), are associated with beneficial outcomes.
• Targeting dietary habits offers a promising avenue for managing and preventing mild cognitive impairment.
