More wine on the brain: healthy reason #93 to drink wine

93. We continue to hear about all of the ways by which wine might be good for the brain: activating memory and learning enzymes, untangling the plaques associated with Alzheimer's disease, and so on. But some have cautiously pointed out that the polyphenols that mediate these effects might not actually get into the brain tissue. Our central circuitry is protected by what is called the "blood-brain barrier" so that toxic molecules can't wander in at will. This of course also creates difficulties in getting medications and helpful nutrients across. Indeed, studies have shown that after oral ingestion, wine polyphenols might not get in to any great degree, suggesting that what we see in a test tube might not be happening inside the brain.
But recent findings from Purdue University show that with regular daily consumption, levels do begin to accumulate in about a week to 10 days. So all of the things we have been saying about regular moderate consumption find more support here.
