Red wine consumption may protect brain from stroke damage, say Johns Hopkins researchers

He also notes that even if further research affirms the benefits of red wine, no one yet knows how much would be optimal to protect the brain, or even what kind of red wine might be best, because not all types contain the same amount of resveratrol. More research is needed, he says.

Dor- says his research suggests that the amount needed could end up being quite small because the suspected beneficial mechanism is indirect. "Resveratrol itself may not be shielding brain cells from free radical damage directly, but instead, resveratrol, and its metabolites, may be prompting the cells to defend themselves," he suggests.

"It's not likely that brain cells can have high enough local levels of resveratrol to be protective," he says. The resveratrol is needed to jump-start this protective enzymatic system that is already present within the cells. "Even a small amount may be sufficient," Dor- says.

Dor- says his ongoing research also suggests some therapeutic benefits to giving resveratrol to mice after a stroke to limit further neuronal damage.
