An author and investigative science journalist, Nina Teicholz advocates for the consumption of foods often painted as dietary villians including butter, meat, and cheese. However, the American dietary policy establishment has shunned them for more than a half-century. In addition, Teicholz advocates for a health-centered lifestyle, low in carbohydrates and high in fat, which may reduce the risk of type-2 diabetes, metabolic disease, and cardiovascular disease. Teicholz shows that Proctor & Gamble (producer of vegetable oil-derived Crisco) and the American Heart Association have financed the “diet-heart hypothesis.” Founder of the nonprofit Nutrition Coalition, Teicholz relies on in-depth dietary research and trial evidence to forward the idea that dietary cholesterol and saturated fat do not cause adverse blood lipids and serious heart disease. In the mid-1960s, before the diabetes and obesity epidemic, Americans consumed an average of 43 percent of calories from naturally occurring fats. The fats stemmed from natural sources instead of industrially produced vegetable seed oil alternatives, which involve high-pressure extraction methods that remove many nutrients and introduce potential contaminants. By contrast, lard, butter, tallow, and other whole-food animal fats feature minimal processing and have been part of healthy diets for millennia. Instead of harming the body, natural saturated fat helps protect the cells from stressors such as oxidation, glycation, and endotoxin buildup.
