Which includes one of by favorite quotes from the book:

"It was not until the late 1960s that Western medical science realized that
adult lactase deficiency -- the inability to digest milk sugar -- was the
rule rather than the exception, and was not really a deficiency at all but
the natural state of affairs. It took this long because most Westerners, in
particular those of northern European background, are capable of digesting
lactose in adulthood. Their lactase levels, and those of a couple of nomadic
African tribes, do not drop off as drastically as those of the rest of the
world's population. The "ethnic chauvinism," as it has been called, of
assuming that everyone could digest milk led to such policies as shipping
surplus powdered milk to famine areas where it could do as much harm as
good. This attitude was overcome only when researchers noticed that about
70% of American blacks are intolerant of lactose, while the figure for
whites is closer to 10%. A few years of study showed that lactose-tolerant
adults are a distinct minority on this planet."
