There's a surprising story to this piece of fruit, and weirdly, it starts with pineapples.
As the video says, strawberries are safe to eat, and they're good for you too. But that doesn't mean the way we grow them is safe.

Also, strawberries and other fruits and vegetables aren't always chemical-free. Check out this comparison of pesticide residues found on fruits and vegetables. There's endless debate about the health impacts of consuming conventional vs. organic produce. The most important thing is to keep eating your fruits and veggies! But the chart below helps you figure out what non-organic produce is most likely to carry additional chemicals. (Psst, the most recent research moves strawberries up to #2!)
