In a world where the pursuit of health pushes us towards organic aisles and fresh produce, this film uncovers a chilling revelation: the very foods promoted for wellness might be our greatest peril. As we navigate grocery store aisles, seemingly benign items like romaine lettuce, cut fruit, and even infant formula hide tales of contamination and legal battles. This gripping exposé dives deep into the unsettling truth about our food, revealing risks where we least expect them.
With every bite, we make choices about our health. But what if those choices, even the most well-intentioned ones, are not as safe as we believe? Poisoned: The Dirty Truth About Your Food challenges our perceptions and urges viewers to question: In the modern food landscape, is anything truly safe? The film is a truly call to action for the officials who have the power to mitigate the danger caused by foodborne pathogens that kill thousands of people every year.

The episode is a journey through the human gut and the process of turning food into energy to keep the body going. Humans have turned eating into culture, a way to celebrate our roots, to bring us together. But food is really just one thing: Fuel. It's where you get the power to live your life. Even when you're sitting completely still, your body needs a lot of energy to stay on. But nowhere is the need for fuel more apparent than when you push yourself to the absolute limit. And the microbiome, the bacteria living in our gut, plays a great role in all this.

Chris turns to longevity doctor Peter Attia to find out how changing his eating habits can help his quest for longevity. Ironically, the answer is to eat no food at all for four long days. If he can bear the hunger, fasting will unlock his body’s own anti-aging powers and give Chris the edge he needs when he tries to hunt for his next meal … by spearfishing off the Great Barrier Reef.

This episode explores the world of human sensation and how it defines reality.
