Dietary nutrients are substances ingested to maintain the function of
the body. These include "carbohydrates & sugars, protein, fats &
cholesterol, vitamins, minerals, fiber, [and] water."

"Prolactin is a single-chain protein hormone closely related to growth
hormone. It is secreted by so-called lactotrophs in the anterior
pituitary. It is also synthesized and secreted by a broad range of
other cells in the body, most prominently various immune cells, the
brain and the decidua of the pregnant uterus.
Prolactin is synthesized as a prohormone. Following cleavage of the
signal peptide, the length of the mature hormone is between 194 and
199 amino acids, depending on species. Hormone structure is stabilized
by three intramolecular disulfide bonds."
"Prolactin induces lobuloalveolar growth of the mammary gland. Alveoli
are the clusters of cells in the mammary gland that actually secrete
milk.
Prolactin stimulates lactogenesis or milk production after giving
birth. Prolactin, along with cortisol and insulin, act together to
stimulate transcription of the genes that encode milk proteins. "

"... For nonvegetarians, prolactin levels were positively correlated
with dietary energy, protein, total and saturated fatty acids, and
oleic acid."

Prolactin may promote initiation of lactation by controlling
"...nutrient partitioning that is necessary to supply mammary needs
for milk synthesis."

Prolactin "direct[s] the flow of nutrients to the process of highest
priority, partly by coordinating nutrient utilization by competing
tissues."

"...[T]here was a significant positive association between plasma
prolactin concentration and increasing saturated fatty acid
intake...and there was a negative association with vitamin C.... For
usual nutrient densities (estimated by quantitative food frequency
questionnaire) there was a statistically significant trend...toward
lower prolactin concentrations with increasing sodium density, and a
marginally significant positive trend...with increasing dietary
density of refined sugars."
