Have you eaten a pickle lately? All of a sudden they're trendy. According to the Boston Globe, pickle obsession is everywhere these days. There are more than 500 Facebook fan pages devoted to pickles. A growing number of restaurants are adding pickle dishes to their menus. You can also join a "Pickle Of The Month" club. All around the world, families are rediscovering the art of pickling at home.Mark Goldberg is a professional chef who says this pickle craze is part of an overall movement to revive "comfort foods" - like cupcakes, chocolates, or mac and cheese. He says when money gets tight, people turn to foods that are cheap to buy, and cheap to make, and pickles satisfy our craving for something crunchy and flavorful, without ruining our diet or budget. Goldberg adds that most people grew up eating pickles at family picnics and barbeques, so there's a "nostalgia factor" involved. That's one reason you may begin to see more restaurants offering seasonal pickled veggies at your table, instead of a bread basket.Know this: No two pickles taste the same. In fact, experts say there are as many varieties of pickles as there are varieties of beer! That's because different manufacturers spend years perfecting the right balance of vinegar, garlic and other ingredients, to create pickles that are salty, sweet, or spicy hot. Pickles are good for you too: Research shows that the acetic acid in pickled vegetables reduces blood pressure, and prevents the formation of fat. Another reason to snack on pickles? One pickle has only ten calories and a single gram of carbs! Plus, eating two tablespoons of vinegar - that's about the amount in one pickle - reduces the blood sugar spike you get after eating lunch. That can go a long way toward reducing your risk of developing type 2 diabetes.
