Because selenium-enriched foods contain much more selenium than natural foods, selenium toxicity is a potential problem, and such foods must be treated with caution. The EU allows up to 300 micrograms of selenium per day, but one long-term study of selenium supplementation showed no evidence of toxicity at a dose as high as 800 micrograms per day.
Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 3 ...
Selenium is toxic in high concentrations. As sodium selenite, the chronic toxic dose for human beings was described as about 2.4 to 3 milligrams of selenium per day. [7] In 2000, the US Institute of Medicine set the adult Tolerable upper intake levels (UL) for selenium from all sources - food, drinking water and dietary supplements - at 400 μg/day. [8]
Almonds: 6 grams of protein. Walnuts: 4.3 grams of protein. Pistachios: 5.7 grams of protein. Cashews: 5.1 grams of protein. Hazelnuts: 4.25 grams of protein. Brazil nuts: 4 grams of protein. Pine ...
While a 3.5-ounce serving of boneless skinless white meat clocks in with 32 grams of protein and only 3 grams of fat, the same amount of dark meat contains just 23 grams of protein and 8 grams of ...
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. [ 1][ 2][ 3] Minerals are one of the four groups of essential nutrients; the others are vitamins, essential fatty acids, and essential amino acids. [ 4] The five major minerals in the human body are calcium, phosphorus ...
Selenium is a vital nutrient in animals, [6] including humans. About 25 different selenocysteine-containing selenoproteins have so far been observed in human cells and tissues. [ 7 ] Since lack of selenium deprives the cell of its ability to synthesize selenoproteins, many health effects of low selenium intake are believed to be caused by the ...
Selenium, 34 Se; Selenium ... Dietary selenium comes from meat, nuts, cereals and mushrooms. Brazil nuts are the richest dietary source (though this is soil-dependent
