Question:Consider the following statements 1. Trans fats are a form of unsaturated fat. 2. Natural trans fats are found in some animal products and are not harmful. 3. Trans fats significantly increases HDL cholesterol. Which of the above is/are true?. -View

(a) Only 2 & 3

(b) Only 1

(c) Only 1 and 2

(d) 1, 2 and 3

Check Answer:

Answer:
Explanation

• Saturated fats are derived from animal products such as meat, dairy, and eggs. But they are also found in some plant-based sources such as coconut, palm and palm kernel oils. These fats are solid at room temperature. Saturated fats directly raise total and LDL (bad) cholesterol levels. • Trans fats are actually unsaturated fats, but they can raise total and LDL (bad) cholesterol levels while also lowering HDL (good) cholesterol levels. • Trans fats are used to extend the shelf life of processed foods, typically cookies, cakes, fries, and donuts. Any item that contains “hydrogenated oil” or “partially hydrogenated oil” likely contains trans fats. Hydrogenation is the chemical process that changes liquid oils into solid fats. • Monounsaturated fats are liquid at room temperature but begin to solidify at cold temperatures. This type of fat is preferable to other types of fat and can be found in olives, olive oil, nuts, peanut oil, canola oil, and avocados. Some studies have shown that these kinds of fats can actually lower LDL (bad) cholesterol and maintain HDL (good) cholesterol. • Polyunsaturated fats are also liquid at room temperature. These are found in safflower, sesame, corn, cottonseed and soybean oils. This type of fat has also been shown to reduce levels of LDL cholesterol, but too much can also lower your HDL cholesterol.
