Researchers have discovered that epicatechin, a compound in dark chocolate, may protect your brain after a stroke by increasing cellular signals that shield nerve cells from damage. An hour and a half after feeding mice a single dose of epicatechin, animals that had ingested the compound suffered significantly less brain damage following an induced stroke. Eurekalert reports: “While most treatments against stroke in humans have to be given within a two- to three-hour time window to be effective, epicatechin appeared to limit further neuronal damage when given to mice 3.5 hours after a stroke. Given six hours after a stroke, however, the compound offered no protection to brain cells.” Dark Chocolate Protects Against Brain Injury
