1. Caffeine just might be good for you.
The health benefits of caffeine are far-reaching — as long as it’s consumed in moderate amounts, says Rania Batayneh, MPH, a nutritionist and owner of Essential Nutrition for You, a nutrition consulting firm. “Caffeine stimulates the release of dopamine, a neurotransmitter that activates an area of gray matter in the brain responsible for alertness and productivity,” she says. And because dopamine regulates mood, a cup of coffee can improve your mood, at least temporarily. As a stimulant, caffeine has also been shown to boost endurance and speed in workouts, though not all experts recommend consuming caffeine pre-workout.
