Is Popcorn a Healthy Snack?
Popcorn is one snack people love to take while watching movies in theaters. Many people take this crunchy snack, but have failed to ask this important question ” is popcorn a healthy snack”?. Popcorn is only healthy depending on how it is prepared. Popcorn is usually made from a grain of corn but some strains called flint corn are specially cultivated as popping corns.
Popcorn was discovered accidentally by a farmer Gonzalo Quádre who left some corn over the heat to dry. Quádre had surplus corn that he decided to dry up some to feed the chickens on his farm. On a summer day, while he was feeding the chickens, he heard a popping sound. As frightened as he was about the sudden noise, he looked down to see a white piece of fluff. Wikipedia.com
What Happens when Corn is Heated.
Popcorn is made with a type of corn that has a strong, hard hull or shell. Inside the shell is a starchy endosphere with 14% -15% moisture which later turn to steem when the kernel is heated. The pressure inside the hull continues building till it exceeds the hull’s ability to contain it. The kernel ruptures and explodes, allowing the contents to expand, cool, and finally set in a popcorn puff 20 to 50 times the size of the original kernel.
Popcorn in its natural state has so many health benefits. However when salt, butter, caramel or other toppings are added to popcorn, it then moves from the realm of healthy to unhealthy junk food. Basically, popcorn is as healthy as what you add to it. Avoid cooking with vegetable oil or olive oil as these can oxidize and damage the delicate polyphenol antioxidants. Oil can added after popping the corn.
