<qa>  What is the most common food in Bangladesh?Supplementation of Se as pills is currently used to treat arsenicosis. But pills are not often well received by people and are expensive for low-income families. Lentils are a common food in Bangladesh and the country already imports lentils from Canada. Saskatchewan SK grown lentils are rich in Se, mostly in form of L-selenomethionine, which is highly bioavailable. The Saskatchewan lentils have mean selenium levels between 425-672 μgkg, with some regions where lentil selenium levels go up to 1884 μgkg. These high Se lentils, incorporated into the daily meals of As-exposed Bangladeshi families, may help mitigate the symptoms of long-term As poisoning in a cost-effective, uncomplicated, and nutritionally beneficial way.
