Healthy eating may help keep the brain younger, study suggests

Following the MIND diet was linked to 20% less gray matter shrinkage, equating to brains appearing 2.5 years younger, according to the 12-year Framingham Heart Study.

  • Published Tuesday in the Journal of Neurology, Neurosurgery & Psychiatry, a study found that closer adherence to the MIND diet was linked to slower brain ageing over about 12 years in over 1,600 Framingham Heart Study Offspring cohort adults.
  • Researchers analyzed over 1,600 participants from the Framingham Heart Study Offspring cohort enrolled from 1999 with an average age 60 and an average MIND diet score just under 7.
  • Quantitatively, researchers found each three-point increase in MIND adherence was linked to 20% less gray-matter shrinkage and a 2.5-year delay in brain aging.
  • Among specific foods, researchers found berries and poultry contributed most to slower brain aging, while sweets and fried fast foods were linked to faster ventricular expansion and hippocampus decay.
  • The researchers caution that associations were stronger in older participants, reinforcing the MIND diet’s potential but noting the observational study cannot prove causation.
