Would you believe that every year around February 14 — Valentine’s Day — men and women (but mainly men!) spend over $1 billion on chocolate? It’s true! What is it about chocolate that people love so much?

If you love chocolate, there’s just something about its sweet taste that’s better than any other type of sweet treat. What’s your favorite type of chocolate?

Do you prefer dark chocolate or milk chocolate?  Would you rather have a chocolate pie, a chocolate cake, or a solid chocolate candy bar? Maybe you like to drink your chocolate in the form of chocolate milk or hot chocolate? Some people even enjoy just snacking on chocolate chips!

People’s fascination with chocolate began over 2,000 years ago. It was way back then in Latin America that the Mayans and Aztecs discovered that they could combine crushed cocoa beans (what chocolate is made from) with water to make the first chocolate-flavored drinks.

During his travels in the 16th century, Christopher Columbus noticed how people in the Caribbean used cocoa beans as money, just like the ancient Aztecs did. He brought these beans back to Europe where they soon became very popular. Many people believed the cocoa beans had magical powers. French doctors were even known to use them to treat “broken hearts.”

By the mid-1800s, the Cadbury Brothers began making chocolate candies to sell in their shop in England. In 1861, Richard Cadbury made the first heart-shaped box of chocolate candies for Valentine’s Day.

Chocolate candies in heart-shaped boxes have been a popular Valentine’s Day present ever since. In fact, the Chocolate Manufacturers Association estimates that approximately 36 million heart-shaped boxes of chocolate candy — about 58 million pounds’ worth — are sold each year around Valentine’s Day.

Besides the fact that people love the taste of chocolate, is there any other reason that chocolate should be so closely associated with Valentine’s Day? Maybe!

Scientists today believe that a chemical in chocolate — phenylethylamine — may be responsible for certain feelings we experience. They believe this chemical may make the body release serotonin, the hormone responsible for making you feel calm, relaxed, and happy.

Americans eat a lot of chocolate every year. Experts estimate Americans eat about 11 pounds per person each year. That’s a lot of chocolate, but not near as much as the world’s leaders in chocolate consumption.

When it comes to eating chocolate, no one beats Switzerland. The Swiss eat an incredible 22 pounds of chocolate per person each year!

My favorite kind of chocolates are Snickers, Hershey’s, M&M, and all the other ones, and the ones that I really like are Snickers. Whenever I go to a store or gas station, I have to get a Snickers, and if I don’t get one, I have a tantrum or fit or I get mad at my mom and don’t talk to her or look at her.

    • WOW! It sounds like you REALLY like your chocolate, Victoria, especially those Snickers! We hope you thank your mom for all the times she HAS let you get a candy bar at the store or the gas station. We think she would really appreciate that! :-)

  7. I think that wonderopolis should take a survey so everybody knows how many people like what chocolate type and which chocolate type is most liked.

    Types of chocolates like: Hershey’s, Reese’s Cups, etc.

    • That sounds like fun, Kolbe! If you think about it, we are already doing that in a way by asking all of our Wonder Friends to share their favorite chocolate in a comment! There are LOTS of different types of chocolate out there, and we’re so glad you guys are sharing your favorites with us! :-)

  15. When I saw that video I had to make it full screen and I sat staring and drooling at it. Yum yum. My favorite chocolate would probably be… I don’t know probably it would be between dark and Ferrero Roche. But I like most chocolate. What’s your favorite, wonderopolis?:)

    • We thought the video for today’s Wonder was GREAT too, Wonder Friend! Thank you for sharing your favorite chocolates with us today. It’s hard to choose only one favorite…there are SO MANY different, yummy kinds and flavors of chocolate in the world! We love them all! :-)

  16. If I had to pick my favorite kind of chocolate, it would have to be truffles! I especially love ones that are given on valentine’s day because most guys put in more effort to buy the chocolates on this day than any other day of the year! It is SO romantic!!! And wonderopolis is SO awesome!!! :-P

  17. I love milk chocolate, chocolate ice-cream and a Mexican chocolate from Oaxaca that is called “Mayordomo” (butler) and has to be melted and added to milk or water to make a drink. I don´t like it with water, although that is the original Aztec and Maya drink, before they even had cows in the Americas. They didn’t add any sweetener either, so it used to be really bitter. (they didn’t have sugar, but they had honey).

    • WOW! Thank you so much for sharing about your Mexican culture today and also what your favorite ways to eat chocolate are, Chela! We really appreciate learning new things from you…you are a GREAT Wonder Friend! :-)

  18. Hi Wonderopolis! I really liked this wonder of the day because chocolate is my favorite thing to eat! It’s interesting that chocolate was made over 2000 years ago. It also surprised me that people spend $1 billion on chocolate. It’s weird that people eat 11 pounds of chocolate every year. I could never eat that much!

    • We think you’re AWESOME for letting us know all the chocolatey facts you learned by exploring this Wonder of the Day®, A! Thanks so much for leaving us a comment to tell us! :-)

    • We think so, too, Josh! It made us hungry to hear all the delicious types of chocolates that our Wonder Friends shared as their favorites! :-)

  19. I like chocolate a lot. When I eat it, I don’t go crazy, but my favorite kind of chocolate is all of the chocolate except for dark chocolate it’s nasty a lot. I like milk chocolate, too. I eat it all the time and it’s good. I wonder what’s your favorite chocolate?

    • We’ve had a few Wonder Friends ask us what our favorite chocolate is, Tomiya, and to be honest, we can’t pick just ONE favorite! We like them ALL! Thanks for sharing YOUR favorite chocolate with us today! :-)

    • We think there are a LOT of Wonder Friends who ate chocolate, chocolate, and more chocolate yesterday, Salima! Thanks for leaving us this SWEET comment to let us know what YOUR favorite chocolate is! :-)

  20. Hi, it’s me again. Please tell me that if you eat 4 chocolates in a row you wont get sick because I just ate 4 chocolates and I think that the wonder of the day for tomorrow will be about horses. Can you please make it horses? I love horses and I think they are beautiful. By the way, who answers all the comments from wonderopolis? I mean, isn’t that kind of tiring and do they answer them from people around the world, too?

  21. Thanks for the recipes. I will definitely ask my mom to make one or all of them. Because all my family LOVES anything to do with chocolate.

  23. I love chocolate and I love each kind of chocolate! How did you get that video of all the chocolates? In my school, Bailey Elementary, we are a big fan of Wonderopolis and it would be cool to find out so I can tell my friends at Bailey!

    • Happy Sunday, Ally! We think Bailey Elementary ROCKS! It makes us happy to hear that we have so many Wonder Friends there! We search high and low for the best videos to go with each day’s Wonder. We found the video for today’s Wonder by searching for yummy ways CHOCOLATE can be made! We thought the video was AWESOME in how it showed making chocolate to be so artistic! :-)

  24. My favorite chocolate is dark chocolate. I especially like Hershey’s dark chocolate! I went to Chicago last summer and went to the Hershey store, it was awesome!!!

  25. My fave kind of treat is french fries dipped in ice cream! It’s salty, sweet, cool, and hot all at the same time! You’ve got to admit that is pretty cool!!!!!!!!

    • That IS really cool, Mak! We know lots of Wonder Friends who agree with you about how yummy french fries dipped in ice cream are. We know one Wonder Friend in particular who likes them dipped in strawberry milkshake! :-)

  26. I think milk chocolate is the best! Dark chocolate is too bitter. But, pretty much all chocolate is delicious!

    • We sure know a lot of Wonder Friends who like milk chocolate, “Love!” Thanks for sharing that it’s a favorite of yours, too! :-)

  27. I like every type except for fillet jelly ones and the super dark chocolate, but I really like cookies and cream white chocolate. Fun, fun, this makes me crave it even more!

    • Thanks for sharing your favorite chocolate, Hj! Cookies and cream white chocolate sounds like a sweet treat! :-)

    • There sure are a lot of different kinds, aren’t there, Kylie? We are SUPER glad you visited this SWEET Wonder of the Day® today and left us this COOL message! :-)

  28. Dear Wonderopolis,
    Thanks you for having this topic as one of your WONDERS!! One thing that I learned reading this article is that on average a person in the USA eats 11 pounds of chocolate each year, and Switzerland has an average of 22 pounds a year per person! That is A LOT of chocolate! Another fact I learned was that scientists today believe that a chemical in chocolate- phenylethylamine- may be responsible for certain feelings we expirience. My favorite chocolate would have to be milk chocolate, but you can never go wrong with chocolate!! Two new vocabulary words that I learned were coco and valentine! Coco is made from crushed up cocoa beans and is put into chocolate. A valentine is a gift or greeting sent or given to a sweetheart (or anyone they want to give it to) on St. Valentines Day. One question I have after reading this is: where did chocolate originate? Thanks again for having this be another WONDERFUL wonder topic!!

Try It Out

Ready to set sail on a sea of chocolate? If you love chocolate as much as we do, that probably sounds like a WONDERful adventure! So recruit a friend or family member (or two or three!) and try out one or more of the following fun activities:

  • How many ways have you eaten chocolate in the past? If you really sit down and think hard about it, you’ll probably be amazed. So brainstorm and make a list. Here are just a few examples of ways you may have eaten chocolate in the past. How many more can you think of?
    • chocolate chips
    • chocolate cake
    • chocolate pie
    • chocolate milk
    • hot chocolate
  • You don’t need a boat to sail on a sea of chocolate. Just head to the kitchen. You might also need to make a trip to the grocery store. Check out the recipes below and choose one or two to make. Double check to make sure you have all the ingredients and then have fun making your own fantastic chocolate creations!
  • Chocolate is closely associated with Valentine’s Day, the holiday of love. Why do people love chocolate so much? Why do YOU love chocolate? Think of someone you love who also loves chocolate. Write a chocolate-inspired poem for them that expresses how much they mean to you. Do you love them more than all the chocolate chips in the world? Perhaps you think the two of you go together like chocolate and peanut butter. Be inventive. Be creative. If you can, put your poem into an electronic form. Can you tweet it to the person? Post it on their Facebook page? Create a PowerPoint presentation with graphics? Show them some love with chocolate poetry and technology…and then have a chocolate candy or two to celebrate!

Still Wondering

Check out Science NetLinks’ A Question of Temperature activity, which shows children how temperature plays an important role in melting and cooling chocolate.
