Popular science [can sprouted garlic still be eaten?] Many people feel that food should not continue to be eaten when it sprouts. In fact, sprouted garlic can be eaten, and the nutritional value will be higher. One study found that garlic that sprouted for 5 days had higher internal antioxidant activities than fresh garlic. However, if the garlic sprouts and becomes rotten and moldy, it cannot be eaten any further. (via BTV I'm a big doctor official micro)
