Question

Eating a diet high in trans fatty acids has been shown to increase circulating levels of LDL. Why do food manufacturers use trans fatty acids like partially hydrogenated vegetable oils in packaged and processed foods?

1) Trans fatty acids increase a food's shelf life.
2) Trans fatty acids increase a food's selling price.
3) Trans fatty acids decrease the likelihood of foodborne illness.
4) Trans fatty acids contain added vitamins and minerals that promote health.

Answer 1

Food manufacturers use trans fatty acids like partially hydrogenated vegetable oils in packaged and processed foods because 1) Trans fatty acids increase a food's shelf life.

Step-by-step explanation:

Food manufacturers use trans fatty acids like partially hydrogenated vegetable oils in packaged and processed foods mainly because they increase a food's shelf life. Trans fatty acids are a by-product of the hydrogenation of vegetable oils, and they can convert liquid oils into solid fats, which helps extend the shelf life of the food products. This is especially important for products that need a longer shelf life, such as packaged and processed foods.

Although trans fatty acids may increase the shelf life of food products, it's important to note that they have been shown to increase circulating levels of LDL (low-density lipoprotein) cholesterol, which is considered bad cholesterol. Consuming high amounts of trans fatty acids can contribute to an increased risk of heart disease. Therefore, it is recommended to limit the consumption of foods high in trans fats and choose healthier alternatives, the correct answer is 1) Trans fatty acids increase a food's shelf life.
