In the developing world, 160 million children are currently undernourished, notes Jessica Fanzo, an associate professor of nutrition at Columbia University in New York City and co-editor of a recently released book, "Diversifying Food and Diets: Using Agricultural Biodiversity to Improve Nutrition and Health Security."
This is partly due to economics, of course, but while food security is a more pressing issue in the developing world, many people there are also not availing themselves of the foods they have ready access to.
"You walk around a small farm in Tanzania, for example, and you'll see many different leafy greens, but then the staple crops like corn are the ones that people end up not only consuming on a regular basis, but also harvesting and selling," Fanzo says. "As such, they forget about what's growing around them and they're missing out on the many benefits that their local biodiversity has to offer."
Fanzo also believes that diet diversity in the developed world could use a serious boost as well-and not only because the American crop system has lost much of its diversity through the years ("A century ago, we had 300 varieties of sweet corn and now we have just 12," notes Fanzo), but also because in the U.S., "peoples' knowledge of what they're eating and where it comes from is probably lower than it is in the developing world, where the farm to fork pathway is much shorter."
Her best advice for a rich and diverse diet: Explore farmers' markets and ethnic grocery stores to sample the plethora of fruits and vegetables, meats, cheeses and eggs they offer in order to "color your diet, because the more color you have on your plate, the better for you-and that's the golden rule," she says.
Purple, yellow, red and orange vegetables all have wonderful and essential properties for health and wellbeing, notes Fanzo, and the same goes for fruits. Each color group offers endless possibilities, she says, especially the greens-where many Americans could afford to diversify much more.
"Most people think they're doing the right thing by eating kale, for instance, because they have read so much about its properties, but that sets a precedent for not being diverse or seeking out other leafy greens, when there are so many other varieties out there that also have amazing and essential properties," explains Fanzo.
Here, we feature some greens you may not have heard of but that are equally, if not more, beneficial to your health and wellbeing.
