From the Vine: Treasure the Many Types of Tomatoes


Until the 19th century, tomatoes were served on pottery that was made with lead. Acid from the tomatoes often leached lead from the dishes, resulting in the diner’s death. The tomato was blamed, which is why Europeans viewed them as “poisonous apples.” But that was then: Today, tomatoes are a big part of the famously healthful Mediterranean Diet.

Botanically, tomatoes are fruit, even though they often are referred to as vegetables thanks to an 1893 government classification for trade purposes. The tomato’s nutrient content is more similar to a vegetable than a fruit, as it contains significantly fewer calories and less sugars than other fruits. Tomatoes are an excellent source of vitamins A and C and a good source of potassium. They contain carotenoids alpha- and beta-carotene, lutein and lycopene. Because lycopene is fat-soluble, it is best to eat tomatoes with a fat source, such as olive oil or avocado, to increase its absorption. Cooking tomatoes before eating them also helps the body absorb lycopene.

Whether raw in salads, sliced on sandwiches or simmered in sauces, tomatoes complement most cuisines and can be prepared with a variety of methods: roasting, grilling, stewing, drying or reducing (such as with soups, chutneys and jams).

In season from June until September, tomatoes are best during summertime when ripe off the vine. Off-season, trucked-in varieties that are bred to withstand the rigors of transportation often are less flavorful. However, with a taste that approaches local, in-season produce, greenhouse-grown tomatoes are becoming popular.

Store tomatoes at room temperature or between 55 degrees and 65 degrees Fahrenheit. Place them in a single layer to avoid bruising. To store ripe tomatoes for more than a few days, especially in a hot climate, place them in the warmest part of the refrigerator.
