"polyunsaturated fat"的定义和意义

What is "polyunsaturated fat"?

Polyunsaturated fats are a type of unsaturated fat found in various foods, including nuts, seeds, fish, and certain vegetable oils like soybean oil, corn oil, and sunflower oil. What sets polyunsaturated fats apart is that they contain more than one double bond in their molecular structure. This makes them remain liquid at room temperature and contributes to their role in supporting heart health. Polyunsaturated fats are known for their ability to lower levels of LDL cholesterol, which is associated with an increased risk of heart disease. Additionally, they provide essential fatty acids, such as omega-3 and omega-6, which our bodies cannot produce on their own but are necessary for proper functioning. Including sources of polyunsaturated fats in your diet, such as fatty fish, nuts, and seeds, can contribute to a balanced and heart-healthy eating pattern.
