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.
