Shane Rutherfurd and colleagues at Massey University
used a new method to analyze the amounts of lysine actually available for
nourishment in 20 commercial cat foods. Lysine is an "essential" amino acid
important in a range of body functions, including absorption of calcium and
building muscle protein.
The researchers found older, traditional tests significantly overestimate the amount of nutritionally available lysine. "This overestimate ranged from 41% to 143% for the moist food and from 18% to 90% for the dry foods," the scientists said.
The study appears in the May 2 issue of the American Chemical Society's Journal of Agricultural and Food Chemistry.
