Abstract

<p>Lentils (Lens culinaris L.) are a source of many essential dietary components and trace elements for human health. In this study we show that lentils grown in the Canadian prairies are additionally enriched in selenium, an essential micronutrient needed for general well-being, including a healthy immune system and protection against cancer. Selenium K near-edge X-ray absorption spectroscopy (XAS) has been used to examine the selenium biochemistry of two lentil cultivars grown in various locations in Saskatchewan, Canada. We observe significant variations in total selenium concentration with geographic location and cultivar; however, almost all the selenium (86-95%) in these field-grown lentils is present as organic selenium modeled as selenomethionine with a small component (5-14%) as selenate. As the toxicities of certain forms of arsenic and selenium are antagonistic, selenium-rich lentils may have a pivotal role to play in alleviating the chronic arsenic poisoning in Bangladesh.</p>

Lentil (Lens culinaris Medik.) is an important pulse crop with annual production of 3-4 Mt across 70 countries (Cubero et al. 2009. DOI 10.1079/9781845934873.0000; pg. 13). Lentils are a good source of protein, carbohydrates, micronutrients and vitamins for human nutrition and is consumed in more than 120 countries. Furthermore, their small seed size and flat shape make them relatively quick cooking and easily decorticated compared to most other grain legumes (Sharpe et al. 2013. BMC Genomics. DOI 10.1186/1471-2164-14-192). The Lentil plant has a bushy growth habit with a height of about 40 cm; the seeds are lens-shaped and usually grow two per pod. ... [more]
