在过去的半个世纪里，通常被认为是蔬菜的栽培番茄（Lycopersicon esculentum）的果实在美国已经成为一种受欢迎和高度消费的食物。西红柿在美国的产量仅次于土豆。因此，西红柿和以西红柿为基础的食品提供了一个方便的基质，通过它可以向人类提供营养和其他与健康有关的食品成分。西红柿和番茄制品富含叶酸、维生素C和钾。相对于植物营养素，番茄中最丰富的是类胡萝卜素。番茄红素是最主要的类胡萝卜素，其次是-胡萝卜素、-胡萝卜素和植物素以及几种次要的类胡萝卜素。番茄红素和其他几种类胡萝卜素的抗氧化活性以及它们在西红柿中的丰富含量使这些食物具有丰富的抗氧化活性。β -胡萝卜素和γ -胡萝卜素的维生素A原活性，它们在番茄制品中的含量适中，以及这些食物的高摄入量，导致了番茄食品中维生素A活性的丰富供应。西红柿还含有其他几种对健康有益的成分，包括维生素E、微量元素、类黄酮、植物甾醇和几种水溶性维生素。
During the last half-century, the fruit of the cultivated tomato (Lycopersicon esculentum), commonly considered a vegetable, has become a popular and highly consumed food in the United States. Production of tomatoes in the United States ranks second only to potatoes. As a consequence, tomatoes and tomato-based foods provide a convenient matrix by which nutrients and other health-related food components can be supplied to human beings. Tomatoes and tomato products are rich sources of folate, vitamin C, and potassium. Relative to phytonutrients, the most abundant in tomatoes are the carotenoids. Lycopene is the most prominent carotenoid followed by beta-carotene, gamma-carotene and phytoene as well as several minor carotenoids. The antioxidant activity of lycopene as well as several other carotenoids and their abundance in tomatoes makes these foods rich sources of antioxidant activity. The provitamin A activity of beta- and gamma-carotene, their modest levels in tomato products, and the high consumption of these foods results in a rich supply of vitamin A activity from tomato-based foods. Tomatoes also contain several other components that are beneficial to health, including vitamin E, trace elements, flavonoids, phytosterols, and several water-soluble vitamins.
