In this study, researchers analyzed the diets and cognitive performance of 72 older adults living in Brookings, South Dakota, and found that higher intake of fiber, vitamins A and E, magnesium, potassium, and carotenoids was associated with better memory and overall cognitive function. The findings were published in the journal Nutrients and add to growing evidence that diet is a modifiable factor in reducing the risk of cognitive decline.
The study also highlighted widespread nutrient shortfalls among the participants. Nearly all reported diets failed to meet recommended intakes for several essential nutrients, including fiber, calcium, and potassium. In contrast to the benefits seen with whole foods and nutrient-dense diets, refined grains – such as those found in white bread, pasta, and many packaged cereals – were negatively linked to cognitive performance, suggesting that dietary quality, not just calorie intake, matters for brain health.
