Consideration 21 - Renal Solute Loads
None of these assertions come from actual clinical trials with goat milk. They come from projections and speculations from other sources. This objection did not show up in the Interim Marketing Authorization. Their other objections did not show up in the Interim Marketing Authorization. These objections did not show up in the pre-market examination.
They will say that goat milk is too high in protein and minerals. They will suggest that this will place too much strain on immature kidneys for the excretion of excess solutes. Perhaps kidneys that are produced by breastmilk or goat milk can handle the solute load. Perhaps kidneys that are produced by infant formulas cannot.
“Renal solute load refers to all solutes, of endogenous or dietary origin, that require excretion by the kidneys… nitrogen and electrolyte content of the diet. …
When an infant is well and consuming a predominately liquid diet ad libitum, his or her ability to excrete un-needed solutes and maintain water is more than adequate even if whole cow’s milk is fed.”

Goat milk and cow’s milk have a similar renal solute load. All infant foods will have to add water to the diets of infants when situations like sweating due to fever or diarrhea occurs.
The following is from a Health Canada website. It is no longer available from them.
“The higher renal solute load of cow’s milk results in a urine osmolality approximately two times higher than that observed in breastfed infants (Fuchs et al., 1992). Usually, there are no adverse clinical sequellae associated with the increased renal solute load;”
“Caprine [goat] milk has been recommended as an ideal substitute for bovine milk, especially for those who suffer from cow’s milk allergy. [CMA] [Rosenblum and Rosenblum 1952; Walker 1965; Van der Horst 1976; Taitz and Armitage 1984; Park 1994; Park and Heinlein2006].”
