A new study published in Neurology has found that older people with higher concentrations of vitamins B, C, D, and E may have better mental functioning. The study was conducted in people who had an average age of 87, and noted that the more vitamins found in the subjects’ bloodstream, the better they performed on mental exercises and tests.
The study yielded two other preliminary findings: first, that Omega-3s were associated with better executive functioning, and second, that people with more trans fats in the blood had lower cognitive scores overall.
It’s important to note that this was a relatively small study, involving only 104 people, so a larger study (ideally with thousands of people) will be necessary to bear these findings out.
