About this episode

The episode discusses recent health news linking vitamin C levels to brain connectivity and other health studies.

HEALTH NEWS Study links low vitamin C levels in the blood plasma to reduced brain connectivity Study: Tart Cherry Supplementation Alters Muscle Protein Profile After Exercise Socioeconomic factors may leave more lasting imprint on children's brains than IQ or parenting style Fasting-mimicking diet reduces gum disease inflammation Low blood pressure shows strongest link to Alzheimer's disease Study links low vitamin C levels in the blood plasma to reduced brain connectivity Hirosaki University (Japan), June 10 2026 (News-Medical) Previous research has uncovered associations between diets higher in vitamin C and lower risk of cognitive impairment in older adults. However, few studies have looked directly at vitamin C levels in blood plasma and potential associations with brain structure and connectivity within brain networks. To help fill that gap, Nagaya and colleagues analyzed magnetic resonance imaging (MRI) scans and plasma vitamin C levels of 2,044 adults over the age of 64. Specifically, they measured the volume of each participant's gray and white brain matter (accounting for individual differences in total brain volume between participants). They also evaluated connectivity…
