摘要：Research suggests that omega-3 fatty acid s (n-3 FAs) play an important role in reducing the risk of heart diseases. The objectives of the current study were to investigate the consumption and the food sources of n-3 FAs in two samples of elderly men living in different geographic locations (coastal and internal regions) of Saudi Arabia. Sixty men from each of the coastal and the internal regions provided a 24-hour recall and 2-day food record and a food frequency questionnaire. Food Processor Plus computer program software (ESHA Version 0.7; Salem, Oregon, 2002) was used to analyze the dietary intake . The intake of total n-3 FAs, alpha-lenolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were higher among the coastal region residents than among the internal residents (P food consumption pattern for food providing n-3 FAs differs by location and coastal residents consume more than twice as much n-3 FAs as internal residents. Nutrition education intervention among internal residents is needed for increasing the consumption of n-3 FAs.
