Trans Fatty Acids Uncovered: IELTS Reading Passage with Questions & Answers

Trans fatty acids, commonly known as trans fats, are a type of unsaturated fat that occur in small amounts in nature but are also artificially created during food processing. For IELTS aspirants, understanding complex topics such as trans fats is crucial, not only for enhancing reading skills but also for preparing to tackle a range of topics that may arise in the exam. This article will explore the nature of trans fatty acids, their impact on health, and their presence in our diet, providing a comprehensive passage for IELTS reading practice.

Trans Fatty Acids: A Closer Look

Trans fats can be found naturally at low levels in meat and dairy products from ruminant animals such as cows and sheep. However, artificial trans fats are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. This process is known as partial hydrogenation.

For many years, trans fats were a staple in various food products due to their ability to improve taste and texture and extend shelf life. Common sources of artificial trans fats include margarine, snack food, packaged baked goods, and some types of cooking oils and spreads.

The Health Implications of Trans Fats

The consumption of trans fats is associated with an increased risk of heart disease. They are known to raise levels of 'bad' LDL cholesterol while also lowering 'good' HDL cholesterol in the blood. The World Health Organization has recommended that trans fat intake be reduced to less than 1% of total energy intake to minimize health risks.

In response to these health concerns, many food manufacturers have reduced or eliminated trans fats from their products. Additionally, several countries have implemented restrictions or bans on trans fats in food products.
