Sweeteners

S01 E03 • Thursday, Sep 9, 2010 • Sep 9

Stefan looks at E number sweeteners used to replace sugar and also learns about the chemicals used to hold our food together. He looks at how E numbers keep the ice out of ice cream, discovers the seaweed that's an E number found in our cakes, and even undergoes MRI scans in an attempt to discover whether E number sweeteners are clever enough to fool our brains.
