When acai is at Wal-Mart and bags of quinoa and chia seeds line the aisles of Costco, it's clear that super-foods have officially reached the masses. These supposedly nutritionally potent foods, which have grown for thousands of years in the Amazonian rainforest, the swamps of Trinidad or the Andean region of Peru, have found their way into American supermarkets and pantries.
Which means that a vacuum exists at the top of the food chain, again, for niche super-foods.
Now appearing at natural foods trade shows and in health food stores, and being touted online, are foods and beverages that are pitched as having even more antioxidants, vitamins and minerals than their predecessors. They are from Africa, India, Nicaragua and the mountains of Greece. Some have a cult following but can be hard to find. Their inherent appeal lies in the fact that they have an aura of uniqueness and exotica.
Still, the question remains: How necessary are these foods to an otherwise healthful diet filled with fruit, vegetables, protein and healthful carbs? Do people need to supplement their lunches with pitaya and baobab?
"It's human nature to want a quick fix, so there's always this great appeal when a new super-food is introduced," said Lori Chong, a registered dietitian and nutritionist at Ohio State University Wexner Medical Center. "But they're really not superior to any of the other fruits and vegetables we can get in the grocery store."
Certainly it's hard not to get lured in. Many of the new super-foods promise enhanced energy and wellbeing with a scoop of this or a shot of that. But Chong strongly advises people to do their homework before trying something new, no matter how healthful it sounds.
"Everything we take will interact with our medications or the other food we are eating," she said. "If it's something odd or not a normal part of your diet, definitely research it."
