“…Selenium deficient soils are found in UK, Australia, central Siberia, New Zealand, Thailand, Africa, Finland, Turkey, Nepal, northeast to south central of China, Denmark, and parts of Bangladesh and India, among others (Rahman et al, 2013;Yasin et al, 2015). Most soils of the tropical zones have low Se concentrations (Sillanpää and jansson, 1992;Christophersen et al, 2013;Gabos et al, 2014a;Matos et al, 2017).…”

Selenium (Se) is an important element that was discovered in 1817, and since the 1960s, it has been regarded as an essential micronutrient for both animals and humans, playing among other functions a relevant role in the antioxidant system of mammals. Inadequate blood Se levels in the human body is a well-known concern in many parts of the world. This malnutrition problem is often due to Se-poor diet, probably as a result of the low Se availability in soils where crops are growing. Nowadays, it is known that not only the total content, but also the inorganic and organic forms of Se contained in foods are important for human nutrition. However, paradoxically some regions of the world present high Se levels in soils causing several functional disorders and diseases in people who live in seleniferous areas. As essential micronutrient, Se should be supplied in controlled amounts to avoid harmful effects. Therefore, taking into account the importance of the soils as a way to ensure the adequate Se supply for the population, this review has dealt with Se behavior in soil environment (e.g., Se forms and adsorption and desorption reactions) and its relevance for the human health. As a final message, the further understanding of Se behavior in soils to predict its availability for crops in different systems will be a significant approach in future studies to establish forms and safe doses of Se to be added in fertilizers. Agronomic and genetic biofortification of staple crops with Se has been suggested as an important tool to improve Se intake by population in Se-poor sites.Index terms: Essential micronutrient; Se adsorption; Se availability; biofortification; human nutrition. RESUMOO selênio (Se) é um elemento importante que foi descoberto em 1817 e reconhecido como elemento essencial para os humanos e animais desde os anos 60. Esse elemento apresenta, dentre outras funções, papel relevante no sistema antioxidante dos mamíferos. Níveis inadequados de Se no corpo humano tem sido uma preocupação bem conhecida em muitas regiões do mundo. Esse problema de desnutrição com Se ocorre frequentemente devido a dietas pobres nesse elemento, o que provavelmente tem relação com a baixa disponibilidade de Se nos solos onde as culturas agrícolas estão sendo cultivadas. Atualmente, sabe-se que, além da quantidade de Se contida nos alimentos, sua forma (e.g., inorgânica ou orgânica) é importante para a nutrição humana. Apesar da deficiência de Se ser um problema em alguns locais, algumas regiões do mundo apresentam níveis altos de Se nos solos, causando várias desordens e doenças nas pessoas que moram nestas áreas consideradas seleníferas. Sendo um elemento essencial, o Se deve ser suprido em quantidades adequadas para evitar efeitos prejudiciais. Assim, levando-se em consideração a importância dos solos como um meio para garantir o suprimento adequado de Se para a população, esta revisão tem abordado o comportamento do Se no ambiente do solo (e.g., formas de Se e reações de adsorção e dessorção) e sua relevância para a saúde hu...

“…[1][2][3][4][5][6][7] After being absorbed by the gut this element plays an important anti-oxidant role, primarily as selenomethionine (SeMet), acting in the treatment and prevention of cancer and cardiac diseases. Despite its relevant characteristics, Se is not present in appropriate levels in most types of food and this low ingestion level has been associated with a massive list of direct and indirect negative health effects.…”

“…Despite its relevant characteristics, Se is not present in appropriate levels in most types of food and this low ingestion level has been associated with a massive list of direct and indirect negative health effects. 6,[8][9][10][11] About half of the world population suffers from the malnutrition of Fe, Zn, Ca, I and Se. 8 Hence, increasing the concentration of bioavailable elements in edible crop tissues (biofortification) has become a promising strategy to increase the intake of some micronutrients.…”

“…Regarding selenium, Thavarajah and Thavarajah 12 carried out a study to determine the potential for Se, Fe, Zn, Ca, Mg, K, Cu and P biofortification of chickpea to improve human micronutrient nutrition. The results showed that the fortified chickpeas are a good source of a range of mineral micronutrients, are low in antinutrients, have moderate levels of carotenes, and are a rich source of phenolic compounds; Rahman et al 6 evaluated lentils produced in farms of Bangladesh, which were grown with the addition of Se containing fertilizers. The authors concluded that Se biofortification in lentil are possible to increase Se intake for Se deficient populations.…”

The effect of selenate and selenite enrichment on mineral composition of a red type of lettuce cv. "Veneza roxa" was evaluated using inductively coupled plasma-optical emission spectroscopy (ICP OES), molecular modeling and principal component analysis (PCA). Both Se species did not show toxicity, while selenate promoted the greatest Se accumulation by the plant. There was an increase of 886 µg of Se per 100 g of fresh sample at different concentrations of selenate, but for selenite the maximum variation was only of 114 µg per 100 g. Selenate promoted the absorption of Mo and S and the reduction of K, Mn and P, meanwhile selenite increased Mn and decreased Mo accumulation. Copper and Fe absorption was negatively affected, Ca and Mg showed a slight increase, and Na and Zn were not affected by Se species. Despite the changes in the nutritional balance, Se-enriched lettuce can still be considered a potential dietary source of this essential element.

Cu, Fe, Mn, Mo, Selenium (Se), and Zn bioavailability from selenate‐ and selenite‐enriched lettuce plants was studied by in vitro gastrointestinal digestion followed by an assay with Caco‐2 cells. The plants were cultivated in the absence and presence of two concentrations (25 and 40 µmol/L of Se). After 28 days of cultivation, the plants were harvested, dried, and evaluated regarding the total concentration, bioaccessibility, and bioavailability of the analytes. The results showed that biofortification with selenate leads to higher Se absorption by the plant than biofortification with selenite. For the other nutrients, Mo showed high accumulation in the plants of selenate assays, and the presence of any Se species led to a reduction of the plant uptake of Cu and Fe. The accumulation of Zn and Mn was not strongly influenced by the presence of any Se species. The bioaccessibility values were approximately 71%, 10%, 52%, 84%, 71%, and 86% for Cu, Fe, Mn, Mo, Se, and Zn, respectively, and the contribution of the biofortified lettuce to the ingestion of these minerals is very small (except for Se and Mo). Due to the low concentrations of elements from digested plants, it was not possible to estimate the bioavailability for some elements, and for Mo and Zn, the values are below 6.9% and 3.4% of the total concentration, respectively. For Se, the bioavailability was greater for selenite‐enriched than selenate‐enriched plants (22% and 6.0%, respectively), because selenite is biotransformed by the plant to organic forms that are better assimilated by the cells.
