Some plants naturally contain the deadly poison cyanide. But humans have developed clever ways of
preparing these plants to transform them into safe foods.

NARRATION

Some plants naturally contain the deadly poison cyanide. Ten bitter almonds contain enough cyanide
to kill a human. But cultivated almonds contain no cyanide so you can enjoy a friand every day and
die of a heart attack instead. Bamboo shoots, happily chomped by Pandas, are chock full of cyanide.
But, once peeled, sliced and boiled they're fine for a stir fry...That's the shoots, not the
pandas.

Raw Lima Beans contain cyanide, but thorough soaking and simmering make them way less dangerous
than a trip to Lima itself. Cassava is cyanide rich, but does no harm when eaten as tapioca
pudding. It just looks gross. While the post mortem odour of bitter almonds is a dead giveaway for
cyanide poisoning, strangely, some of us are genetically programmed NOT to be able to detect this
scent. In which case probably best to stick to wine appreciation.
