The 5th house rules the stomach and digestion. Mars (Mangal) is the planet of fire, heat, and the oven (Tandoor).
When Mars sits in the 5th house, it creates a very specific, fiery digestive system. Dr. Sharma reveals a classic Lal Kitab *Nishaniya*: This person will have an absolute obsession with eating Tandoori Roti (bread baked in a clay oven) or foods cooked directly over an open flame ("tandoori rotiyan bohat chabata hoga").
Their strong digestive fire (Jatharagni) craves heavy, fire-baked foods. However, they must be careful not to overdo it, as excess Mars energy in the 5th house can lead to severe acidity and stomach ulcers.
