The objective of this work was to study identify trends of consumption and types of vegetable oils consumed by some Saudi families . Another objective was to study the fatty acid composition of the mostly consumed oils and to compare to Saudi standards.
The study included 500 family, representing all Riyadh locations. Source of information was thirty years old house holds (64%), with education level and middle income level were most of the families.
(5000-10000 SR) Results reveled that the main dietary fats consumed are vegetable oils with a consumption rate of 20Kg/year.Trend of consumption of the main vegetable oil consumed are ,corn oil and sunflower oil were for cooking and palm oil was for frying and olive oil was for salad. Fatty acid composition results showed that the three types of oils contains monounsaturated and die and polyunsaturated and that is beside variable amounts of saturated fatty acids. The dominant saturated fatty acids consumed by the studied families was plasmatic acid. The study showed that the consumed oil contains a considerable amount of the essential fatty acid leinolenic a which may supply them with some of their daily needs from this fatty acid. The studied oils contain the trans fatty acid eliadic(C18:1t) with a ratio of up to 3% in sunflower oil.
