Effect of chronic feeding of Remington's diet and fasting on rat plasma composition

Rats fed on Remington's low iodine diet (supplemented with iodine) and on rat chow were compared as to their plasma composition. There are significant differences in plasma glycerol, aceto-acetate, beta-hydroxybutyrate and in several amino acid concentrations, mainly lysine and tryptophan. 24 hours of fasting lowered the differences between the groups, but some aspects remained unchanged, i.e. the low lysine and tryptophan concentrations in Remington diet fed rats. The use of the Remington diet therefore, provoked a functional lack of these amino acids, even when their concentration in the diet was higher.
