Transcript:

Well, David, I'd divide them into three categories. There are risks that were identified where we knew there was a risk, probably very small and something where you've got to tell people that could be a risk but we're not asking you to do anything different. And a classic example of that was acrylamide. So in about 2001, 2002, some Swedish scientists discovered that if you cook certain kinds of food, particularly starch-containing foods at a high temperature, like making chips or French fries, then you create this chemical called acrylamide which can be carcinogenic. So when you discover that do you say to people, "Stop eating chips?" Do you say to people, "Cook your chips to low temperature so they're not nice and crisp and possibly burn yourself on the fat while you're measuring the temperature?" Or do you say, "This is not a new risk, we think it's very small. Be aware of it but carry on doing what you were doing before."

According to the audio, which of the following statements are true about acrylamide and its discovery?

* Click on the correct answers

Acrylamide was discovered by Swedish scientists around 2001-2002. Acrylamide is only found in potato chips. Acrylamide is formed when cooking starch-containing foods at high temperatures. The discovery led to an immediate ban on cooking chips and French fries. The risk of acrylamide is considered to be very small. People were advised to stop eating chips after the discovery.

Option 3: "Acrylamide is formed when cooking starch-containing foods at high temperatures."

Explanation: The text explains that acrylamide is created when cooking certain starch-containing foods at high temperatures, which directly supports this statement.

Option 4: "The discovery led to an immediate ban on cooking chips and French fries."

Explanation: The text indicates that there was no immediate ban; instead, it discusses how people were advised to be aware of the risk without changing their cooking habits, making this statement incorrect.

Option 5: "The risk of acrylamide is considered to be very small."

Explanation: The text mentions that the risk of acrylamide is considered very small, which directly supports this statement.

Option 6: "People were advised to stop eating chips after the discovery."

Explanation: The text clearly states that people were not advised to stop eating chips, but rather to be aware of the risk, making this statement incorrect.
