Researchers conducted this cross-sectional study to explore the connection between vitamin D intake and brain cortical thickness in older adults. The sample consisted of 263 cognitively unimpaired candidates aged 65 and up who were part of the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) trial (an ongoing study testing the effects of a 3-y diet intervention on cognitive decline). Dietary vitamin D had no effect on brain cortical thickness. Total and supplemental vitamin D intakes were associated with cortical thickness in regions vulnerable to AD in cognitively unimpaired older adults.
