Age-related brain atrophy, the gradual loss of neurons and shrinkage of brain tissue, is a natural part of aging, which can lead to cognitive decline and other neurological issues. While so far aging cannot be prevented, recent research from an 18-month dietary intervention offers hope that lifestyle and dietary changes can slow brain aging. A new international study, led by Ben-Gurion University of the Negev as part of the DIRECT PLUS Brain MRI trial, has brought to light how blood sugar control can significantly impact brain health.
