The fat profile of raw pistachios consists of saturated fats, monounsaturated fats and polyunsaturated fats. Malondialdehyde results from lipid peroxidation of polyunsaturated fatty acids. The triglycerides contain a mixture of saturated, monounsaturated, and polyunsaturated fatty acids. Marine omega-3 polyunsaturated fatty acids appear to reduce the risk. They are enzymatically derived from arachidonic acid a 20-carbon polyunsaturated fatty acid. Coconut oil contains only 6% monounsaturated and 2% polyunsaturated fatty acids. These contain high levels of polyunsaturated fatty acids. Many fatty acids are unsaturated; some are polyunsaturated (e.g., those derived from linoleic acid). These esters are characterized by high levels of polyunsaturated fatty acids, especially alpha-linolenic acid. Vegetable oils are rich in various polyunsaturated fatty acids (PUFA). Everything bagels contain about 2 grams of fat consisting of mostly monounsaturated and polyunsaturated fat. The edible seed oil is a source of polyunsaturated fatty acids. Each variety has its own unique levels of monounsaturated, saturated, and polyunsaturated fats. The percentage of polyunsaturated fatty acids (PUFAs) is inversely correlated with insulin resistance. Pumpkin seed oil has an intense nutty taste and is rich in polyunsaturated fatty acids.
