A Coffee a Day Keeps the EMH Away?
In a recent study, scientists have found that a daily dose of caffeine blocks the disruptive effects of high cholesterol linked to Alzheimer’s disease. Just one cup of coffee a day could protect the blood-brain barrier (BBB), which protects the central nervous system, from harmful colesterol. Caffeine appears to protect BBB breakdown by maintaining the expression levels of tight junction proteins. These proteins bind the cells of the BBB tightly to each other to stop unwanted molecules crossing into the central nervous system. Maybe that’s why Janeway is so sharp.
