Resveratrol is a molecular compound that is found prominently in red wine. One study found that resveratrol is able to repair damaged blood-brain barriers—places that allow blood to enter the brain—resulting in a slowing of the progression of Alzheimer’s disease. Researchers say resveratrol seems to be able to shut down harmful molecules created by the body’s own immune system and reverse the damage that they cause.
The brains of people with Alzheimer’s disease usually contain tissue inflammation that has been caused by harmful immune molecules released by the body. These harmful molecules can pass through the blood-brain barrier. With the help of resveratrol, the inflammation is lessened. Because of the way that resveratrol helps to repair certain parts of the brain, it is thought that resveratrol stops Alzheimer’s disease from progressing as quickly as it normally would.
During the study, researchers were able to see a 50 percent reduction in the levels of several types of harmful immune molecules in participants. Folks who cannot or do not drink wine for any reason don’t need to worry though. Resveratrol can also be found in red grapes, raspberries, and dark chocolate.
