Coffee is one of the most consumed beverages worldwide, but when it comes to energy, there’s a lot of confusion about what actually helps and what might be working against you. In Episode 195 of the Real World Nutrition Podcast, Shelley Rael, Registered Dietitian Nutritionist, breaks down the difference between coffee, caffeine, and energy, and what you should really know about each.
Shelley discusses the pros and cons of caffeine, how much is too much, and why “energy” drinks may not provide the kind of energy you actually need. Shelley explains how caffeine works as a central nervous system stimulant and clears up the difference between stimulant energy and the actual energy your body uses (hint: that comes from food, not caffeine). You’ll also learn about caffeine tolerance, side effects of overuse, and when energy drinks can become dangerous.
Whether you love your morning brew or reach for an afternoon energy boost, this episode will help you use caffeine wisely to support your health, not drain it.
