Since animal fats are a rich source of dietary saturated fat and cholesterol, they quickly became the object of his derision. It also were quick to endorse industrial seed oils, more kindly referred to by now as “vegetable oils,” as a healthier alternative to traditional animal fats.Īround the same time, an ambitious physiologist and researcher named Ancel Keys introduced his diet–lipid hypothesis, in which he presented data that seemed to suggest a link between saturated fat and cholesterol intake and heart disease. In the late 1940s, a small group of cardiologists who were members of the still somewhat new American Heart Association received a $1.5 million donation from Procter & Gamble thanks to this generous infusion of cash from the makers of Crisco, the AHA now had sufficient funding to grow its national profile as a physician’s organization dedicated to heart health. How did industrial seed oils go from being classified as “toxic waste” to enjoying the title of “heart healthy” fats? As first documented by Nina Teicholz, in her book, The Big Fat Surprise, the story involves a scandalous combination of donations to medical organizations, dubious scientific research, and unsubstantiated marketing claims. From Toxic Waste to “Heart Healthy”: The History of Seed Oils

But there was another plus that appealed to their business sensibilities: the oil could be chemically altered via a process called “hydrogenation” to turn it into a solid cooking fat that resembled lard. Cottonseed oil was consigned to the status of “toxic waste” until the enterprising Procter & Gamble realized that all that unwanted cottonseed oil could be used to produce soap. Around the same time, oil was discovered in Pennsylvania it quickly displaced cottonseed oil, which had long been used for lighting, as a fuel source. While soap had historically been made from rendered pork fat, Procter and Gamble were an innovative pair and decided to create a new type of soap from vegetable oils. In 1870s Cincinnati, two soapmakers-William Procter and James Gamble-decided to enter into business together. So how did these industrial byproducts end up on our plates? #industrialseedoils #processedfood #seedoils #toxins Industrial seed oils were originally used in the soapmaking process. How, then, did these oils come to occupy such an influential position not only in the Standard American Diet but in “”Westernized” diets around the world? The story is strange indeed. In fact, industrial seed oils, the highly processed oils extracted from soybeans, corn, rapeseed (the source of canola oil), cottonseed, and safflower seeds, were only introduced into the American diet in the early 1900s.

Unlike traditional fats such as olive oil, coconut oil, butter, ghee, and lard, industrial seed oils are a very recent addition to the human diet.
