Higher levels of vitamin C levels were linked to healthier brain structure in older adults, suggesting a potential role for nutrition in brain aging.That’s according to new research from Japan, published in the journal PLOS ONE.The observational study included 2,044 participants living in Hirosaki City, Japan, who were originally included in a study exploring dementia and heart disease risk.The average age was 69, and 61% of them were female.SKIP THE MULTIVITAMIN: 5 NUTRIENT-RICH FOODS RECOMMENDED BY DOCTORS INSTEADThe researchers measured the participants’ vitamin C levels using blood samples and performed MRI scans to calculate the volume of gray matter and white matter in their brains.Even after accounting for external factors like age, smoking habits, diabetes and other lifestyle behaviors, they found that those with lower vitamin C levels appeared to have lower brain tissue volumes and weaker structural network patterns.Higher levels of vitamin C levels were linked to healthier brain structure in older adults, suggesting a potential role for nutrition in brain aging.
