Simple food for brain protection – scientists discover unexpected benefit

Scientists have found that regular nut consumption may be linked to better memory and overall cognitive performance in people without a stroke. An analysis of observational data from 1,771 people showed a connection between nut intake and cognitive test results, as well as brain volume in physically active participants. Researchers emphasize that the findings indicate a correlation, not proof that nuts prevent dementia.

Scientists have found that regular nut consumption may be linked to better memory and overall cognitive abilities. This conclusion was reached after analyzing data from a long-term observation of 1,771 people with an average age of 61. Participants regularly reported their diet and underwent tests for memory, information processing speed, and reasoning ability. In people without a stroke, higher nut consumption was associated with better results on memory and general mental ability tests. This relationship persisted even after accounting for age, education, smoking, physical activity, and overall diet quality. The connection was particularly noticeable among participants who had poorer diet quality or engaged in little physical exercise. Researchers also found a link between nut consumption and larger total brain volume, but this association was observed only among the most physically active participants. However, scientists did not determine the exact portion needed for a potential positive effect. The median nut intake was only 1.3 grams per day. The authors emphasize that the results require confirmation in larger studies and indicate a correlation, not proof that nuts can prevent dementia.
