Food fanatic Stefan Gates and his intrepid Gastronuts go on another wild culinary adventure to discover the truth about how we eat, what we eat and where it comes from. Along the way they indulge in harebrained experiments and crazy cooking, and eat the world's weirdest food from scorpions to pig's ears. Farting is an essential part of human digestion but it always provokes embarrassment or laughter. So what would happen if we were to try and stop ourselves from parping? The Gastronuts put theory into practice by cooking up the world's fartiest foods, catch their trumps in a swimming pool and see what a whole week's worth of stored up wind would do to the human body.
