The Connection Between Good Nutrition and Good Cognition
January 15, 2012
A study that looked at biomarkers in the blood to correlate vitamins and brain function found very clear links between nutrition and brain health.
A new study goes deeper in understanding the connection between good nutrition and a healthy brain. Previous studies have linked individual vitamin deficiencies to cognitive decline. But new research looks at a wider range of vitamins, and even better, it uses biomarkers in the blood to correlate vitamins with brain health, both good and bad.
Many studies exploring the relationship between nutrition and cognitive health rely on people’s personal reports of their diets — a notoriously unreliable way to gather personal nutritional information. For this reason, the researchers behind the current study decided to use a more objective means of studying the nutrition-brain link: they looked at biomarkers in the blood to measure the vitamin levels in 104 participants. They also had participants take tests to measure thinking and memory function, and 42 participants had MRI scans to measure their brain volume.
The researchers found some striking connections between nutrition and brain health. People who had higher levels of B family vitamins, as well as vitamins C, D, and E had higher scores on cognitive tests than people with lower levels. The same positive relationship was found for omega-3 fatty acids, which have previously been linked to better brain health.
