How the Right Carbohydrates Reduce the Risk of Dementia

New scientific data suggests that the quality and quantity of carbohydrates we consume daily play a significant role in brain health and the risk of dementia and Alzheimer's disease. While age remains the primary risk factor, lifestyle – particularly diet – can improve cognitive function and promote healthy aging. An important element in evaluating carbohydrates is the glycemic index, which measures how quickly blood sugar rises after consuming a food. Foods with a high glycemic index, such as white bread, cause rapid increases in sugar, while foods like fruits, legumes, and whole grains have a milder effect. Studies show that people with a low to moderate glycemic index diet have a lower risk of dementia compared to those who regularly consume high glycemic index foods. In conclusion, careful carbohydrate selection, with an emphasis on quality, can help protect brain health and reduce the risk of dementia and Alzheimer's disease.
