Dietary guidelines for Americans.

Since the guidelines were first issued back in 1980, Americans have gotten slightly healthier, except for children, got significantly bigger, gotten significantly bigger (especially children), and gotten very, very confused about what they should be eating.

It is suggested that methionine is required for select components of the antibody response, which effect might be related to T-cell help.
Amino acid diets and maximal growth in the rat.
From the late 1940's until the present there has been considerable controversy over the question of whether there is a specific compound in protein which in creases the growth rate of animals fed an amino acid diet and an examination of the literature indicates that maximal growth rate has, in fact, never been ob tained routinely.
Adaptation of rats to diets containing different levels of protein: effects on food intake, plasma and brain amino acid concentrations and brain neurotransmitter metabolism.
The results indicate that protein intake appeared to be related to the animal's ability to maintain brain total IAA content between some upper and lower limits, and was accomplished initially through downward adjustment of protein intake and subsequently through an increase in catabolic capacity for the amino acids.

Sulfur amino acid and methyl donor status of corn-soy diets fed to starting broiler chicks and turkey poults.
It is concluded that (within the limits of the experimental model) corn-soy type diets contain an adequate amount of total sulfur amino acid for chicks, but not poults, when sufficient choline or betaine are provided.
