Are superfoods all that they’re cracked up to be? There’s plenty of worldwide hype about eating chia seeds, goji berries and quinoa - but what benefits do they really bring?
This documentary looks at what superfoods do for people and more. How is the healthy eating boom influencing agriculture and business? There are more and more restaurants serving superfoods in Germany. Florian Klar of Bochum opened the first superfood bistro in the Ruhr region about a year ago. He buys in all types of food, using local suppliers when he can, but he also uses exotic superfoods in his meals.
Quinoa, goji berries and chia seeds can now all be found in supermarkets as well. The food industry has discovered selling these products is lucrative and changed its product selection accordingly. Superfoods are simply that a foodstuff contains a high amount of nutrients. "Every country has its own superfood,” says nutritionist Matthias Riedl. Blueberries, flax seed, blackcurrants, and kale are all superfoods native to Germany.
The film also takes viewers to Bolivia, a key quinoa exporter, to see how the hype has influenced farming there. Exports of the so-called "Inca corn” quadrupled between 2007 and 2013. The rising price of quinoa on global markets has led Andean farmers to increase the size of their fields. Yet after just two straight years of quinoa harvests, the soil is already exhausted and barren.

PERSPECTIVES | The Igbo are one of Nigeria's largest ethnic groups and among them is a minority of practicing Jews that claim to be the descendants of a lost tribe of Israel, but the Jewish state doesn't recognize them. Our Elinor Lalo has the story.

Probability is the backbone of science, but how well do you understand it? Odds are, not as well as you think; it is a surprisingly subtle concept that is often misunderstood, sometimes even by professionals who use it to guide crucial and far-reaching decisions. In this program, experts from technology, physics, medicine, and programming explore the slippery side of probability and the powerful role it plays in modern life.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness? Experts in the field of physics, including David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the history of quantum mechanics, current theories in the field, and possibilities for the future.
