Diet and Dementia Risk: New Food for Thought
The combination of foods individuals consume may influence dementia risk as much as which foods they eat, new research suggests. Investigators from the University of Bordeaux in France examined "food networks" and found that individuals whose diets consisted mainly of highly processed and starchy foods were significantly more likely to develop dementia than those whose diets also included processed foods and incorporated a wider variety of healthy foods.
@shipra The current findings align with multiple previous studies that show strong associations between specific food groups and the risk for cognitive aging and dementia. For example, the Mediterranean diet, which emphasizes high intake of plant foods and low consumption of meat and dairy, among other factors, is associated with lower risk for cognitive impairment and Alzheimer disease. Similarly, the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet ― which promotes intake of berries, green leafy vegetables, and other plant-based foods and limits consumption of saturated fat and animal foods ― has also been linked to a lower risk for dementia. However, Samieri noted that much of this previous research focused on quantity and frequency of foods.
