If you have a rotten egg smell…
you may eat too much meat. Meat is a product that is heavy on the digestive system, which is why people who eat a lot of meat on a daily basis may have a repulsive sulfuric odor like rotting eggs. This specific odor is caused by the high content of sulfur-containing amino acids in meat — particularly red meat. There is no harm in these amino acids, but they need to be digested well, which is not that common.
