Based on the provided text, which of the following statements about trans fats is/are true?

  • A: Trans fats are exclusively produced by natural processes in plants.
  • B: Trans fats are known to contribute to coronary heart disease.
  • C: The U.S. FDA required nutritional labels to include trans fat content and has ordered a ban on their production by 2021.
  • D: Denmark and Switzerland have banned artificially produced trans fats.

Explanation

The text explicitly states that 'trans fats can contribute to coronary heart disease,' confirming option B. It also mentions that the 'FDA requires nutritional labels to include information on trans fat content. In addition, the FDA has ordered U.S. food manufacturers to stop producing trans fats in foods by 2021,' supporting option C. Finally, 'Some countries, such as Denmark and Switzerland, have already banned artificially produced trans fats in foods,' validates option D. Option A is incorrect as the text describes trans fats being produced by 'hydrogenating vegetable oils,' implying an artificial process, and directly contradicts 'artificially produced trans fats.'
