Scientists have developed a method to make lettuce darker and healthier using ultraviolet (UV) light-emitting diodes (LEDs). Steven Britz of the U.S. Department of Agriculture and his colleagues used low-power LEDs that exposed lettuce to ultraviolet B (UVB) light for 43 hours. The lettuce was noticeably darker than plants not exposed to the UVB. They have not quantified this effect, but the lettuce darkening increased with the intensity of the light. Darker lettuce, like spinach, is known to be more nutrient dense than its lighter counterparts, such as iceberg.
