Low-Sugar Diet Early in Life Linked to 46% Lower Alzheimer's Risk

A UK Biobank study used World War II-era sugar rationing as a natural experiment.

People exposed to less sugar before and just after birth later showed lower rates of dementia, Alzheimer’s disease, depression, and anxiety.

The low-sugar group also had some favorable brain MRI differences, suggesting lasting effects on brain health.

The findings point to pregnancy and early childhood sugar exposure as a possible factor in lifelong dementia risk.
