Nutrients, phytochemicals and antioxidant activity in wild populations of Allium ampeloprasum L., a valuable underutilized vegetable

Wild leek can be considered as a low energy food, being a good source of fiber and zinc, compared to its cultivated relatives, and has revealed a predominance of polyunsaturated fatty acids, linoleic acid being the main fatty acid. Additionally, the natural yield of this species, although lower than other cultivated Allium species, was found to be stable and well-adapted to human-disturbed environments. For these reasons, this non-conventional wild bulb should be revalorized as a good alternative to increase the diversity of vegetables consumed and enhance the quality of current occidental diets.
