Abstract
Polyunsaturated fatty acids not synthesized in the body but required for normal metabolism called essential fatty acids (EFAs), these fatty acids are linoleic (C18:2), linolenic acid (C18:3) and arachidonic acid (C20:4). In the last 20 years, epidemiologic studies, clinical investigations, and animal experiments have expanded our knowledge of the properties of dietry fatty acids in health and disease and in growth and development. So, this study aimed to study impact of individual or mixed plant oils and ground (walnut, pecans, almond and sesame (sources of Omega-3 fatty acids) on cardiovascular heart diseases of rats.
Four types of oils and ground (walnut, pecans, almond and sesame) were the main materials of this study. The oils and ground were added to basic diets individually as 5% and 10% of total diet and mixtures as 10% of total diet.
Moisture and ash value were determined according to AOA C, (1999), protein value was determined according to method described by the AOA C, (1995), fat content was determined according to AOA C, (1995) and carbohydrate was estimated by difference. Fatty acids content oils were estimated by HPLC and method described in AOA C, (2000).
