Organic foods are associated with improved nutritional properties and healthier foods by the general public, as well as non-polluting sustainable agricultural practices. However, although it is clear that organic foods are less polluting because of the way they are grown, it is not clear whether their overall health properties are better. Within the health properties of foods we find the bioactive or nutraceutical properties of foods. In the case of vegetables, the main compounds involved in these properties are total phenols and total carotenoids, and both are involved in increasing the total antioxidant activity of vegetables, both in their water- and fat-soluble forms. Therefore, in this work these four parameters have been quantified in different vegetable species, such as chard, garlic, pumpkin, spring onion, baby lettuce, lemon, orange, bell pepper, leek, pear tomato and round tomato, all of them organically and conventionally grown. From the results obtained it can be said that organic cultivation does not produce a greater nutraceutical or bioactive value in the vegetables and fruits studied, since in all the parameters quantified there have been different responses. Thus, in some species these parameters were higher in those grown organically, in others in those grown conventionally, and in others there were no significant differences.
