Gallery: 12 Affordable, Organic Superfoods You Should Be Buying

In the past few years, more and more Americans have been trying to live healthier lives by purchasing organic foods at the supermarket. But, what exactly does "organic" mean, and why is it so expensive? 

Organic produce and meats are grown without pesticides, not engineered with genetically-modified organisms (GMOs), and aren't fed antibiotics or growth hormones. 

Organic farmers are faced with rigorous paperwork to ensure their crops meet the correct standards. Conventional farmers, not so much. Not to mention, small organic farms do not receive federal money like large, conventional farms.

Due to higher farming prices, this means that organic superfoods seem even more expensive. Superfoods are nutrient-dense foods that promote health, which might include improving heart-health, boosting brain function, preventing inflammation, etc.

Sometimes these powerfoods can be hard to afford, that's why we've put together a list of the most affordable, organic superfoods. And some of them might already be in your pantry.
