Scientists have genetically engineered a “golden lettuce” that provides significantly higher amounts of beta-carotene, which the body converts into vitamin A, vital for immune function, vision, and growth.
Researchers from Valencia Polytechnic University in Spain used genetic modifications and high-intensity light treatments to boost beta-carotene levels in lettuce without disrupting photosynthesis. The extra beta-carotene, stored in specialized cell compartments, enhances its bioavailability. This innovation could help combat vitamin A deficiency, a widespread issue affecting millions, particularly in malnourished populations.
