humans on the planet can’t digest the milk sugar called lactose, that the best route to calcium balance may not be massive milk intake These complications help remind us that milk was designed to be a food for the young and rapidly growing calf, not for the young or mature human Milk Nutrients Nearly all milks contain the same battery of nutrients, the relative proportions of which vary greatly from species to species Generally, animals that grow rapidly are fed with milk high in protein and minerals A calf doubles its weight at birth in 50 days, a human infant in 100; sure enough, cow’s milk contains more than double the protein and minerals of mother’s milk Of the major nutrients, ruminant milk is seriously lacking only in iron and in vitamin C Thanks to the rumen microbes, which convert the unsaturated fatty acids of grass and grain into saturated fatty acids, the milk fat of ruminant animals is the most highly saturated of our common foods Only coconut oil beats it Saturated fat does raise blood cholesterol levels, and high blood cholesterol is associated with an increased risk of heart disease; but the other foods in a balanced diet can compensate for this disadvantage (p 253) The box below shows the nutrient contents of both familiar and unfamiliar milks These figures are only a rough guide, as the breakdown by breed indicates; there’s also much variation from animal to animal, and in a given animal’s milk as its lactation period progresses The Compositions of Various Milks The figures in the following table are the percent of the milk’s weight accounted for by its major components ...unsaturated fatty acids of grass and grain into saturated fatty acids, the milk fat of ruminant animals is the most highly saturated of our common foods Only coconut oil beats it Saturated fat does raise blood cholesterol... a given animal’s milk as its lactation period progresses The Compositions of Various Milks The figures in the following table are the percent of the milk’s weight accounted for by its major components ...
