Today’s Wonder of the Day was inspired by Steve. Steve Wonders, “Why Do People Like Pineapple On Their Pizza?” Thanks for WONDERing with us, Steve!

There have been many great debates over the ages. Which came first: the chicken or the egg? Why did the chicken cross the road? Is it soda or pop? And is Coke or Pepsi better? Michael Jordan or LeBron James? The list goes on and on.

Recently, however, a new debate has run rampant across social media, dividing friends and families and possibly threatening the survival of civilization itself. The question: does pineapple belong on pizza?

For fans of Hawaiian pizza (a classic pie topped with pineapple and ham), the answer is a clear "Yes!" However, many others feel that adding super-sweet pineapple to an otherwise salty and savory pizza pie is an abomination akin to adding watermelon to a cheeseburger.

What do you think? Do you love pineapple on your pizza? Or does fruit on a savory pizza pie make you cringe? Those seem to be the only opinions in this debate. There doesn't seem to be much middle ground. When it comes to pineapple on pizza, most people either love it or hate it.

And the numbers are pretty close. A pizza delivery smartphone app called Slice conducted a survey of over 9,000 people about pineapple on pizza. The results? A majority of 54% of respondents said "No!" to pineapple on pizza. That means 46% gave pineapple a "thumbs up!"

Pizza purists often claim that pineapple is not a classic Italian ingredient and therefore does not belong on pizza. However, others point out that there are plenty of new and interesting types of pizzas out there that don't seem to offend people the way pineapple does, from buffalo chicken to Philly cheesesteak.

If you happen to love Hawaiian pizza, you may be surprised to learn that the pineapple-and-ham concoction was invented in Canada in the 1960s. It does happen to be popular in Hawaii today, although residents of Oregon, Maine, California, and Nevada order it more frequently than Hawaiians.

People who like pineapple on their pizza might be able to back up their preference with a bit of science. Of the five basic flavors — sweet, salty, bitter, sour, and savory — our bodies naturally crave both sweet and salty foods.

This is why certain salty and sweet combinations are very popular. For example, who doesn't like classic salty/sweet combinations like chocolate-covered pretzels, peanut butter and jelly sandwiches, and salted caramel?

Pineapple on pizza proponents say the sweet pineapple combines with the salty tomato sauce to provide the same salty/sweet punch as other classic combinations. It may also be healthy. Experts point out that pineapple contains valuable nutrients, including manganese, vitamin C, and vitamin B2.

So if you love pineapple on pizza, keep eating it! Who's going to stop you? If you're not a fan, don't worry about it. Let others eat what they want to eat and you can keep chowing down on your own personal favorite combination of pizza toppings.
