Junk foods are bad for the body as they are loaded with fats, sugars, calories and have very little nutritional value. Consuming junk foods regularly has been linked to an increased risk of obesity and chronic diseases, such as cardiovascular disease, type 2 diabetes, non-alcoholic fatty liver disease and even some cancers.

However, experts believe that occasional indulgence will not impact a healthy diet. Hence, National Junk Food Day is celebrated on July 21 every year in the United States to let people indulge in junk foods that are not usually included in their daily diet.

This National Junk Food Day, go ahead and grab your favorite junk food and munch on it to your heart's desire. You may also share it with your loved ones to make this day extra special.

And if you decide to share photos of your favorite treats on Instagram but are not sure about the caption, fear not as we've got you covered. Here are 15 quirky and fun-filled Instagram captions that will go perfectly well with your photos. (Courtesy: women.com)
