Ocean Greens: The Superfood From the Deep

A world of green vegetables exists beneath the ocean's surface, offering unique flavors and significant health benefits. Sea lettuce (Ulva lactuca) is one such example, a nutrient-dense 'blue food' that provides omega-3s, zinc, iron, and vitamins A, D, and B12, alongside a distinct peppery, umami taste.

For generations, Indigenous coastal communities have incorporated sea lettuce into their diets. Its presence in Blue Zones, like Okinawa, Japan, highlights a strong connection between these marine vegetables and longevity. Experts view blue foods, including sea lettuce, as critical for mending the global food system in the face of climate change and a growing population.
