National Popcorn Day is observed on January 19, 2019. Popcorn, also known as popping corn, is a type of corn that expands from the kernel and puffs up when heated. This snack is usually served salted or sweetened. In North America, it is traditionally served salted, often with butter or a butterlike topping. However, sweetened versions, such as caramel corn and kettle corn, are also commonly available.
Depending on how it is prepared and cooked, some consider popcorn to be a health food, while others caution against it for a variety of reasons. Air-popped popcorn is naturally high in dietary fiber and antioxidants, low in calories and fat, and free of sugar and sodium. This can make it an attractive snack to people with dietary restrictions.
Popcorn can also have non-food applications, ranging from holiday decorations to packaging materials. There are various techniques for popping corn. Along with prepackaged popcorn, which is generally intended to be prepared in a microwave oven, there are small home appliances for popping corn. These methods require the use of minimally processed popping corn. (With material from: Wikipedia)
