Result
Your answer: —  Â·  Correct: C
Explanation

A 'trans-fat free' campaign signifies that food products are not made from partially hydrogenated oils, which are the primary industrial source of trans fats [4]. Hydrogenation adds hydrogen to liquid vegetable oils to make them solid, creating trans-fatty acids as a byproduct [2]. Statement 1 is correct because avoiding trans fats implies avoiding these hydrogenated oils. Statement 2 is incorrect because trans fats occur naturally in meat and dairy products from ruminant animals; thus, 'trans-fat free' does not necessarily mean the product is free of all animal fats [1]. Statement 3 is correct as trans fats are scientifically linked to serious cardiovascular risks, including raising LDL (bad) cholesterol and lowering HDL (good) cholesterol, leading to heart disease [1]. Therefore, the campaign assures consumers that the oils used are less likely to damage cardiovascular health.
