The findings, published in the Journal of Agricultural and Food Chemistry, said that mixing lettuce, one of the indispensable vegetables in the Mediterranean diet, could be a good idea as not all lettuce varieties have the same antioxidant effect.
Free radicals harm our body by causing, in the best of cases, ageing and, in the worse, serious diseases.
Lettuce is rich in antioxidants, as it contains compounds like phenolic acids, flavonoids, anthocyanins, and vitamins A and C, among other things, the researchers said.
