Food Unwrapped S09E09 - Revisited: Brazil Nuts, Coconut Oil, Goat

Jimmy Doherty, Kate Quilton and Matt Tebbutt reveal unusual, intriguing and surprising secrets behind the food we eat. Jimmy takes to the skies above Israel to join the battle to protect the bell pepper crop from the Mediterranean fruit fly, but is amazed to learn that it's not insecticide that he's helping to spread across the desert. Can you put dishwasher salt on your chips? Jimmy visits an extraordinary underground salt mine in Sicily, with a vast network of tunnels leading to a subterranean salt processing plant. Kate visits Vietnam to find out if coconut oil is any healthier than other oils. She also heads to the Amazon rainforest to investigate rumours that the Brazil nuts on UK supermarket shelves are all radioactive.
