Poorly prepared food depraves the blood and damages the digestive system.

Original passage

Scanty, ill-cooked food depraves the blood by weakening the blood-making organs. It deranges the system and brings on disease, with its accompaniment of irritable nerves and bad tempers. The victims of poor cookery are numbered by thousands and tens of thousands. Over many graves might be written: “Died because of poor cooking;” “Died of an abused stomach.”
