Coastal communities are experiencing rapid changes on their livelihood due to the degradation of coastal areas and growing tourism. We analyze the changes in the diet of two fishing communities from the southeastern Brazilian coast, in regard to their consumption of animal protein. Using multivariate methods, we followed the diet of 32 households through the 24-hour recall method (three days per month, September 1998 to August 1999) in order to compare the niche breadth of the communities, and to verify the relationships between fish consumption and socioeconomic characteristics. The nutritional quality of the diets is analyzed. Even with the partial abandonment of fishing activities, fishing activity still guides fish consumption. Nutritional adequacy is above the recommended levels for protein intake, but is below it for food energy. Non-local industrialized food items influence the increase of the niche breadth. The abandonment of livelihood activities that historically assured Caiçara's self-sufficiency are resulting in the food delocalization.
由于沿海地区退化和旅游业发展，沿海社区的生计正经历快速变化。我们分析了巴西东南海岸两个渔业社区在动物蛋白消费方面的饮食变化。我们采用多变量方法，通过24小时回忆法（1998年9月至1999年8月，每月三天）跟踪了32户家庭的饮食，以比较社区的生态位宽度，并验证鱼类消费与社会经济特征之间的关系。我们分析了饮食的营养质量。即使部分放弃了捕鱼活动，捕鱼活动仍然主导着鱼类消费。营养充足率高于蛋白质摄入量的推荐水平，但低于食物能量的推荐水平。非本地工业化食品影响了生态位宽度的增加。历史上保证凯萨拉人自给自足的生计活动的放弃正导致食物的非本地化。
