What is Trans Fat?

Trans Fat

Quick Answer

Trans fat is a type of unhealthy fat that can be found in some processed foods. It is created through a process called hydrogenation, which makes liquid oils solid and can increase shelf life.

Overview

Trans fat is a type of fat that is not good for your health. It is made by adding hydrogen to liquid oils, which turns them into solid fats. This process makes the fats last longer on store shelves, which is why they are often found in processed foods like baked goods, snacks, and fried foods. When you eat trans fats, they can raise your bad cholesterol levels while lowering your good cholesterol levels. This imbalance can lead to heart disease and other health problems. For example, many fast-food restaurants use trans fats in their frying oils, which can contribute to unhealthy eating habits. Understanding trans fats is important in nutrition and dietetics because they can have serious health implications. Health experts recommend limiting or avoiding trans fats altogether to maintain a balanced diet. Reading food labels can help you identify and reduce your intake of these harmful fats.
