Over two billion people worldwide suffer from micronutrient deficiencies. Biofortifying vegetables can enhance intake through the diet. This study assessed biofortification of indoor-grown baby-leaf lettuce using aeroponics. Four experiments, each, were conducted by adding different concentrations Zn (from 10 to 450 µM) or Cu 3 250 into a nutrient solution. A fifth experiment was simultaneously solution optimal concentration I (5 and Se (13 µM), chosen on basis previous works, (250 (150 results obtained in first four experiments. Leaf biomass, mineral concentrations, chlorophylls, carotenoids, phenols, flavonoids, nitrates, antioxidant capacity measured 21 days after transplanting. Higher Cu, Zn, I, led an increase their leaves, without affecting growth leaf quality plants. The simultaneous application with other elements induced higher accumulation leaves compared when is applied alone. One hundred grams biofortified Se, would provide 6.1%, 35.3%, 263.0% Adequate Intake for respectively, 4.5% Population Reference Zn. Our suggest that biofortifying these minerals practical convenient way integrate micronutrients diet reducing yield lettuce.
