De Langen—differed from each other in so many ways. Trying to pinpoint the difference responsible for heart disease was like looking for the proverbial needle in a haystack. During the Second World War, though, the same populations acted as their own controls, and many researchers, including Ancel Keys, were understandably intrigued. When Keys first heard about this curious downturn in deaths, he began examining the incidence of heart disease in different countries (as best he could, given the discrepancies in systems of diagnosis and record keeping) and concluded that the rates did indeed vary.
That looked a lot like those of the Burrs’ rats. By then, the Burrs had moved to Hawaii to study pineapple cultivation and had left the field entirely. George Burr, in other words, had many good reasons for putting the question of essential fatty acids on the back burner of his scientific stove in the 1930s and focusing instead on how sugar is metabolized. But in 1943, when Ralph Holman approached him for a new project, he had recently acquired an instrument, an advanced spectrophotometer, and saw an opportunity for using it to probe more deeply into fats.
Essential fats had been found (incorrectly) to be required only by rats, and cholesterol, first isolated from gallstones in the early 1800s, grabbed all the attention because it was the first fat that could be measured. Found exclusively in animal tissues, cholesterol turns a convenient blue-green color when it is treated with a strong acid (specifically, a mixture of sulfuric and acetic acids). When Holman entered graduate school in chemistry in 1941, his laboratory manual contained only one procedure related to fats: the Liebermann-Burchard method for determining cholesterol.
