Researchers studied how adding selenium to Cordyceps militaris mushrooms affects their nutritional value and ability to prevent obesity. They found that selenium enrichment increased the mushroom’s carbohydrates and fiber content, and enhanced beneficial compounds like terpenoids and alkaloids. In mice fed a high-fat diet, both regular and selenium-enriched Cordyceps militaris reduced weight gain and improved metabolic health equally well. The study suggests these mushrooms work against obesity by using multiple active compounds that target different biological pathways simultaneously.
