No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it. There are no known biological systems that could accomplish this, and the energy required to produce and expel fire would be impractical for a living organism. Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **

It is still a better option than refined semolina, but it is not considered a true whole grain product. **
