Answer 1

Major health benefits of Polyunsaturated fatty acids

• Polyunsaturated fatty acids are those fatty acids which contain two or more double bonds in the fatty acyl chain. They cannot be synthesized by the body, and has to be obtained from dietary sources.
• Polyunsaturated fatty acids (PUFA’s) represent a healthy type of fats (as are most unsaturated fats). It is recommended that consumption of moderate amounts of polyunsaturated (and monounsaturated) fat as opposed to saturated and trans-fats can be beneficial for health.
• Omega-3-fatty acids, which are a class of PUFA’s, are one of the best types of fatty acids that can be consumed.
• Omega-3-fatty acids can be obtained from cold water fish, fatty fish, walnuts, peanuts, almonds, olive oil and canola oil.
• PUFA’s are beneficial in lowering the triglyceride levels of the body, and finds mention in the American Heart Association’s dietary recommendation for people with high triglyceride percentage in their body.
• PUFA’s have been shown to have anti-hypertensive effects, meaning they can help in lowering high blood pressure.
• There are also reports which mention that consumption of PUFA’s has been linked to improvement of people suffering from depression.
• Another class of PUFA’s include the omega-6-acids, which also provides benefits such as controlling blood sugar, reducing the risk of diabetes, and lowering the blood sugar.
• The 2010 Dietary Guidelines for Americans suggests that an adult should obtain no more than 25% to 30% of daily calories from fats, and most of these fats should be poly- or mono-unsaturated.
• Saturated fats should be less than 6% of daily diet. For a 2,000 calorie diet, that's approximately not more than 120 calories, or 13 grams of saturated fat a day.
