Scientists are rethinking bamboo as a powerful new superfood
Bamboo shoots may be far more than a crunchy side dish. A comprehensive review found they can help control blood sugar, support heart and gut health, and reduce inflammation and oxidative stress. Laboratory and human studies also suggest bamboo may promote beneficial gut
Researchers found a tipping point for video gaming and health
Moderate video gaming appears harmless, but heavy gaming may take a toll on young people’s health. Researchers found that students gaming more than 10 hours a week had worse diets, higher body weight, and poorer sleep than lighter gamers. Below that level, health outcomes were
