Background: Selenium is one of the essential trace elements in various biological body functions. The main source of Selenium in the body is food, one of which is vegetables. Vegetables collect Selenium from the soil which is then converted into various chemical species of Selenium. Such species should be recognized since each has different biological activities. Objective: The aim of this review was to identify chemical species of Selenium in vegetables as well as the benefits and toxicity for the body. Methods: Reference searches were done in Pubmed and Google Scholar databases with the keywords Selenium speciation in plants, selenite, selenate, selenomethionine, selenocystine, and se-methylselenocysteine Results: The results of speciation in several types of vegetables showed that the chemical species of Selenium abundantly found in vegetables were selenomethionine (SeMet), selenocystine (SeCys2) and se-methylselenocysteine (Se-MeSeCys), gamma-glutamyl-Se-methyl-selenocysteine, and inorganic species. Both Selenium-enriched vegetables and the species contained therein have a variety of benefits for the body. However, excessive consumption can also cause toxic effects. Conclusion: The chemical species of Selenium in vegetables can be either organic or inorganic. Both types of species have different benefits and toxic effects.

Dietary Deficiency

For an element to be considered essential it should satisfy three criteria: (1) it must be present in living matter; (2) it must be able to interact with living systems; (3) a dietary deficiency must consistently result in a reduction of a biological function, preventable or reversible by physiological amounts of the element. Ideally, essentiality should be established in more than one species and confirmed in more than one laboratory. Since 1970, vanadium, fluorine, silicon, nickel and arsenic have been shown to meet all the criteria listed above, and evidence from one laboratory has indicated that tin may have an essential biological role in the laboratory rat. A review is presented of the evidence on which the essentiality of these elements has been established and, when known, an indication of their biochemical functions. The possible significance of these ‘newer’ trace elements to the health of man and animals is discussed.

Positive Effect

The aim of the present review is to summarize selenium’s connection to pests. Phytopharmaceuticals for pest control, which increase the pollution in the environment, are still widely used nowadays regardless of their negative characteristics. The use of trace elements, including selenium, can be an alternative method of pest control. Selenium can repel pests, reduce their growth, or cause toxic effects while having a positive effect on the growth of plants. In conclusion, accumulated selenium protects plants against aphids, weevils, cabbage loopers, cabbage root flies, beetles, caterpillars, and crickets due to both deterrence and toxicity.
