Can a Good Diet Improve Cognitive Function?

Can a good diet improve cognitive function?

Check out this answer from Consensus:

The collective evidence suggests that a good diet can indeed improve cognitive function, particularly in older adults. The Mediterranean and MIND diets show the most promise, with consistent findings supporting their benefits for various cognitive domains. While certain dietary supplements also show potential, the evidence is less robust. Overall, adopting a healthy dietary pattern, possibly in combination with other lifestyle interventions, appears to be an effective strategy for enhancing cognitive health.

The relationship between diet and cognitive function has been a subject of extensive research. Various studies have explored how different dietary patterns and specific nutrients can influence cognitive health, particularly in older adults. This synthesis aims to present the key insights from multiple research papers on whether a good diet can improve cognitive function.

Key Insights

• Mediterranean Diet and Cognitive Function:
  • The Mediterranean diet (MeDi) is associated with improved cognitive function, particularly in domains such as global cognition, episodic memory, and executive function6 7 10.
  • Randomized controlled trials (RCTs) and cohort studies indicate that adherence to the MeDi can lead to significant improvements in cognitive performance, although the results are sometimes inconsistent6 7.
• MIND Diet:
  • The MIND diet, which combines elements of the Mediterranean and DASH diets, has been shown to be positively associated with cognitive function in older adults. It may be superior to other plant-rich diets for improving cognition1.
• Dietary Supplements:
  • Certain dietary supplements, such as B vitamins, DHA, EPA, and flavonols, have shown potential benefits for cognitive function, particularly in memory and executive function2 3 8.
  • However, the evidence is mixed, and more well-designed trials are needed to confirm these findings3.
• Healthy Dietary Patterns:
  • General healthy dietary patterns, including high consumption of fruits, vegetables, and polyphenol-rich foods, are associated with better cognitive function. These patterns may influence multiple brain processes, including neurotransmitter pathways and synaptic transmission4 5 9.
• Multi-domain Interventions:
  • Interventions that combine diet with other lifestyle factors, such as exercise and cognitive training, show more significant effects on cognitive function than diet alone9 10.

The answer is yes, but exercise is probably more robust. Restricting required nutrients can impact brain function. Even if all nutrient requirements are met, certain micronutrients are capable of having specific effects, e.g., cocoa flavanols acutely increase elasticity of blood vessels which would be hypothesized to be good for brain function.

While there is almost no data that provides evidence that diet has any effect on cognitive function in people with no impairment in cognitive function, there is a growing body of literature that a diet rich in omega three fatty acids may be beneficial in preventing or slowing the progression of Alzheimer’s disease or dementia. The same is true for physical activity. Here the data are even stronger that regular physical activity can prevent the onset of dementia or Alzheimer’s disease. It is likely that the anti-inflammatory effects of each is the mechanism.

There is plenty of evidence that a bad diet (lots of processed food high in saturated fat, added sugar and salt) can impair cognitive function, but very little robust evidence that a healthy diet can improve it. That said, a healthy diet (lots of fruit and veg) may improve mood, and there is a growing body of evidence for this. But mood is not cognition. So my answer (given current evidence) has to be unlikely.

Considering the number of poorly nourished people who may appear well nourished (or over-nourished), I will say “likely” or “possible” since nutrients (vitamin D, B12, etc.) may be low or omega-3 fatty acids or phytochemicals are not at optimal intake levels. However, there is also newer evidence indicating that overconsumption of micronutrients can also be harmful, so finding a balance is important. Remember to watch out for “experts” who use fear with the promise of disease prevention to convince you otherwise. And to echo and expand on Dr. Evans comments, exercising is key (with nutrition) to the recipe for cognitive and other health outcomes.

Diet is a major route for a variety of essential micronutriens required for proper brain function. There is substantial evidence that show dietary uptake of micronutrients (e.g. Se) can improve learning ability in animals. Even if a proper diet can not boost cognitive ability, an improper one impairs that for sure!

There are some mouse experiments showing evidences that gut microbiota significantly improved cognitive functions.
