Four major findings
- Women who consumed the most quantities of saturated fat foods (e.g. red meat and butter) were 60 percent more likely to have change scores than those consuming the least.
- Women who consumed the most monounsaturated fat (which is found in foods like olive oil, avocados, nuts and seeds) were 44 percent less likely to have change scores
- Consumption of polyunsaturated fats and trans fats was not associated with any changes
- Total fat was not associated with any changes
Interpretation
This study shows that a heart healthy diet is probably also healthy for the brain and replacing unhealthy fats in the diet with healthy ones will do double duty and help preserve cognitive function as well.
Okereke, the lead author notes that strategies to prevent cognitive decline in older people are particularly important. Even subtle declines in cognitive functioning can lead to higher risk of developing more serious problems, like dementia and Alzheimer disease.
