The intake of vegetables and fruits has been shown to reduce the risk of multiple diseases in many different populations. Various components of these foods have been investigated to explain the protective effects. Carotenoids, a class of phytochemicals found in these foods, have been investigated for links between their oxidative, provitamin A, and cellular properties and disease risk reduction. Many nutrition-based studies employ dietary questionnaires to estimate intakes for associations with disease. Reliable assessments of the components of these foods are necessary for accurate quantification of intake. While databases have been published, they vary greatly due to differences in methodology, growth conditions, and handling. In addition, data relevant to foods grown and consumed in Latin America and Costa Rica are scarce. In this paper, we employ a quality-controlled method for analyzing foods to obtain data on vegetables and fruits that are common to the Costa Rican diet. The data is presented in tables and compared to databases from the United States and Europe.
在许多不同人群中，摄入蔬菜和水果已被证明可降低多种疾病的风险。人们对这些食物的各种成分进行了研究，以解释其保护作用。类胡萝卜素是这些食物中发现的一类植物化学物质，人们已对其氧化、维生素A原和细胞特性与降低疾病风险之间的联系进行了研究。许多基于营养的研究采用饮食问卷来估计摄入量与疾病之间的关联。对这些食物成分进行可靠评估对于准确量化摄入量是必要的。虽然已经发布了数据库，但由于方法、生长条件和处理方式的不同，它们差异很大。此外，与拉丁美洲和哥斯达黎加种植和消费的食物相关的数据很少。在本文中，我们采用一种质量控制方法来分析食物，以获取哥斯达黎加饮食中常见蔬菜和水果的数据。数据以表格形式呈现，并与来自美国和欧洲的数据库进行比较。
