Sweet Tooth in Dementia

Although eating sweet in high amounts can lead to an increased risk of developing dementia, it is not the cause of dementia.

Eating excessive amount of sweets is observed in patients with Alzheimer’s disease and both the sporadic Frontotemporal dementia (FTD) and familial FTD.

A prospective cohort study found that individuals who drink more sweetened beverages tend to have a higher risk of dementia and Alzheimer’s disease in comparison to those who don’t. The risk was especially higher in those who drank more than 7 sweetened beverages per week. In addition to this, high blood sugar levels can increase the risk of dementia, especially Alzheimer’s disease [1, 2].

However, the research behind it is not conclusive and more work needs to be done in order to really explore the connection of sweets and dementia.
