    Journal: Int J Med Mushrooms; 2017; 19(7):653-665. PubMed ID: 29199586.
    Abstract:
    The objectives of this study were to investigate mineral profiles of 35 species of edible mushrooms collected in China; we compared nutritional values and tolerable values with the official recommended daily intakes (RDIs), maximum intake limits, and provisional tolerable weekly intakes. A total of 19 minerals were detected in edible mushrooms by inductively coupled plasma optical emission spectrometry. The results showed that the mushroom samples had a low percentage of RDI for the minerals calcium, iron, magnesium, manganese, zinc, potassium, and sodium and a relatively higher percentage of RDI for copper and molybdenum. The samples also had a very high percentage of RDI for chromium and selenium. The level of heavy metals in a majority of the mushrooms was above the limited level, and only concentrations of copper and zinc were safe in all mushrooms. In conclusion, the mushrooms collected in China are a good source of minerals such as molybdenum and selenium but are badly contaminated with aluminum, arsenic, cadmium, chromium, and lead.
