Many foods contain caffeine, including guarana, decaffeinated coffee, chocolate cake, matcha desserts, yerba mate, energy bars, bottled water, kombucha, and breakfast cereal. While caffeine can have health benefits such as improved memory, concentration, and exercise performance, excessive consumption can lead to negative effects like jitteriness, anxiety, and trouble sleeping. It's important to consume caffeine in moderation, with most healthy adults considered safe at 300-500 mg per day. Individual sensitivity varies, so paying attention to how caffeine affects your body is crucial.
