It's the one day of the year that you don't have to feel guilty about eating your favorite junk food. Today is National Junk Food Day.

National Junk Food Day is celebrated each year on July 21st. According to Holiday Insights, there is no official origin to the start of the day and Congress of course does not recognize it as a holiday. All that aside, it's still a fun day to celebrate.

Today will give you the opportunity to eat Oreos, Cracker Jacks, Cheesecake bites, M&Ms, and chips with no guilt to be felt. With today's heat index rising to over 100 degrees, it might be a great day to stay in the air conditioning with your favorite ice cream dessert. Just a few ideas for you for this glorious day.

My advice to you, don't put Twinkies on your pizza.
