Scientists fermented mealworms (a sustainable food source) with a medicinal fungus called Cordyceps militaris to make them more nutritious and appealing. The fermented mealworms had much higher protein, fiber, and a cancer-fighting compound called cordycepin compared to regular mealworms. This technique creates a healthier, more environmentally friendly alternative protein food that could help feed growing populations while reducing the environmental impact of traditional livestock farming.
