The Environmental Working Group, a nonprofit that is focused on public health, lists twelve fruits and vegetables that they call the "Dirty Dozen" because they reportedly contain 47 to 67 pesticides per serving.
The "Dirty Dozen" are:
Sweet bell peppers
Spinach, kale and collard greens
The group suggests avoiding purchasing these fruits and vegetables if they've been conventionally grown and instead opting for organic. Yes, buying and eating organic fruits and vegetables is ideal, but not always financially feasible. At least not for me. Instead of buying organic, why not learn to eat seasonally and grow some of the fruits and vegetables in your garden yourself?
From the "Dirty Dozen" list I'm growing: strawberries, bell peppers, spinach, kale, potatoes, lettuce and collard greens. And you know what? I'm growing them in a container garden (both traditional and repurposed plastic containers) on a porch that is roughly the size of a jail cell. You can too. When you're growing your own fruits and vegetables in your garden you can be sure you know exactly how they were grown. Plus, it has been fun showing my nephews and niece that they're favorite vegetables don't come in plastic bags from the grocery store. They sowed the seeds that resulted in seedlings that will mature and produce a harvest. They've being growing with their vegetables all along the way.
If you have the space try gardening in raised beds. You can lighten the amount of soil you use in containers, and the cost, if you create a false bottom in large containers.
