Prominent Features of Commonly Consumed Allium Species and Effects on Human Health

Objective: Natural foodstuffs consumed daily contain compounds which are recuperative for healing of
diseases. Plants belong to genus Allium contain these components highly. Vegetables often consumed raw or
cooked like onion, garlic, leek are included in this group. Compounds they contain such as phenolic compounds,
vitamins, fatty acids, essential amino acids, glycosides show that these products are very important for health.
The aim of this study is to summarize, based on scientific literature, the components good for health found in
three of most consumed species belonged to the genus Allium as onion (Allium cepa), garlic (Allium sativum) and
leek (Allium porrum) and the kinds of disorders which of these components are good for healing them.
Materials and Methods: In this article, the studies on the bioactive components of Allium species,
especially onion, garlic and leek and how they act on human health have been systematically reviewed.

Results: Clinical studies have proven that these plants, which have high antioxidant and antimicrobial
properties, are important for human health.

Conclusion: Components like quercetin, allicin, kaempferol have provided to obtain positive results in
the treatment of various diseases from cardiovascular disorders to cholesterol, from diabetes to tumor formation.
