GAS IS THE RESULT ........
Foods high in certain carbs and fibres don't get break down completely in small intestine by enzymes.

We have 38 trilion bacteria in large intestine. When they eat this left over food, they produce
Hydrogen
Carbon Dioxide
Methane
Hydrogen Sulphide ( remember, rotten egg smell !!! )
These gas builds up and come out as FART .....!!!!
Some foods get digested before reaching bacterial hub. They don't produce gas. They are ----
Rice Potato Banana Egg Meat
