Liebig also studied respiration, at one point measuring the "ingesta and excreta" of soldiers, a bodyguard of the Grand Duke of Hessen-Darmstadt, for an entire month. Liebig drew upon his work in plant nutrition and plant and animal metabolism to develop a theory of nutrition, which had significant implications for cookery. Liebig saw similarities between plant and animal metabolism, and suggested that nitrogenous animal matter was similar to, and derived from, plant matter.
