We’ve heard for years about the dangers of eating too much fat or salt. But there have never been recommended limits for sugar on Canadian food labels, despite emerging research that suggests the sweet stuff may be making more of us fat and sick. In the fifth estate’s season premiere, Gillian Findlay digs into the surprising science — and the reaction from the food industry — to reveal The Secrets of Sugar. Has the sugar industry been hiding an unsavoury truth from consumers?

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.

Bacteria, viruses, but also fungus spores, algae, pollen, and even insects: microorganisms are constantly drifting through the sky. How can so many living beings find their way into the air and be circulating in our atmosphere? How do they survive? What is their influence on our lives and our entire living world? Biodiversity, health, climate - scientists are only now discovering just how much this discreet airborne "plankton" affects our lives and the entire ecosystem on Earth. But despite its many virtues, this magic matter is now under threat from human activity. With help from experts and using 3D visual effects, this scientific investigation will take us to the heart of a world that is still very little understood, and will reveal the diversity and fragility of the air we breathe.

When Hannah Fry is diagnosed with cervical cancer at the age of 36, she starts to interrogate the way we diagnose and treat cancer by digging into the statistics to ask whether we are making the right choices in how we treat this disease. Are we sometimes too quick to screen and treat cancer? Do doctors always speak to us honestly about the subject? It may seem like a dangerous question to ask, but are we at risk of overmedicalising cancer? At the same time, Hannah records her own cancer journey in raw and emotional personal footage, where the realities of life after a cancer diagnosis are laid bare.

Fresh or processed, white or red - how does meat measure up? It's been getting a lot of bad press recently with new links to cancer and heart disease. But 98 per cent of us in the UK are still meat eaters. Chris Bavin, a greengrocer by trade and a carnivore by nature, wants to know if he can keep meat in his diet and stay healthy. He teams up with top scientists to put meat under the microscope and examine it as never before. They follow 40 volunteers on a groundbreaking study to find out exactly how much meat is good for us, test whether paying more for chicken makes it any better for us, discover a way to dramatically reduce the health risks associated with processed meats and reveal an unlikely lean supermeat that won't break the bank.

As the narrative goes, fat is bad. Well, it's actually more nuanced than that. The type of fat you eat is more impactful on your health than the quantity. George Zaidan examines triglycerides, the varied molecules that make up fat, and how to identify which types of fat you are consuming.
