Mycoprotein is a protein-rich food derived from a type of fungus, specifically the Fusarium venenatum species. It is commonly used as a meat substitute in various vegetarian and vegan products, providing a source of high-quality protein along with essential amino acids. Mycoprotein is often found in products like Quorn, which is a popular brand that offers meat alternatives. This ingredient is low in fat and high in fiber, making it a nutritious option for those looking to reduce meat consumption. Mycoprotein is also environmentally friendly, as its production requires less land and water compared to traditional livestock farming.
