UPSC CSE Prelims 2011

A company marketing food products advertises that its items do not contain trans-fats. What does this campaign signify to the customers ?

  1. The food products are not made out of hydrogenated oils.
  2. The food products are not made out of animal fats/oils.
  3. The oils used are not likely to damage the cardiovascular health of the consumers.
Which of the statements given above is/are correct ?

EXPLANATION

Correct Option

The campaign signifies that the food products do not contain industrially produced trans-fats. This claim has specific implications for the manufacturing process and the health benefits for consumers.

  • Statement 1: Trans-fats are primarily formed through the industrial process of partial hydrogenation of vegetable oils. This process converts liquid oils into solid fats, which are then used in various food products. Therefore, a company advertising "no trans-fats" indicates that its products are not made using such hydrogenated oils. This statement is correct.
  • Statement 3: Trans-fats are known to elevate low-density lipoprotein (LDL) cholesterol levels and decrease high-density lipoprotein (HDL) cholesterol levels, thereby increasing the risk of cardiovascular diseases. Consequently, the absence of trans-fats in food products is generally considered beneficial for cardiovascular health. This statement is correct.

Incorrect Options

  • Statement 2: While some animal fats, such as those found in dairy and meat from ruminant animals, naturally contain small amounts of trans-fats, the term "trans-fats" in the context of food product advertising predominantly refers to industrially produced trans-fatty acids. A claim of "no trans-fats" does not necessarily mean the complete absence of all animal fats, as these may contain naturally occurring trans-fats. Therefore, this statement is incorrect.
  • Option (a) is incorrect because statement 3 is also correct.
  • Option (b) is incorrect because statement 2 is not correct.
  • Option (d) is incorrect because statement 2 is not correct.
