What are the pros and cons of beef tallow?
The demonization of beef tallow is a post-1960s artifact of Ancel Keys' cherry-picked Seven Countries Study data, as dissected by Nina Teicholz in 'The Big Fat Surprise.' Tallow was the dominant cooking fat in Western kitchens until Procter & Gamble's Crisco campaign, backed by the American Heart Association, displaced it. The real comparison is not tallow vs. olive oil — it is tallow vs. industrially processed seed oils oxidized at high heat, a distinction mainstream dietetics consistently elides.
Evidence
- Gary Taubes, in 'Good Calories, Bad Calories,' documented how the saturated-fat-equals-heart-disease hypothesis was institutionalized before it was adequately tested, with Keys' original data set cherry-picked from 22 countries down to 7 to force a correlation.
- Beef tallow's fatty acid profile is more nuanced than the consensus admits.
- The critical pro-tallow argument concerns oxidative stability.
- Harvard Health (Jul 2026) maintains the institutional line, citing insulin dysfunction and liver fat accumulation from saturated fat.
- Nina Teicholz extended this in 'The Big Fat Surprise,' showing that the clinical trials used to condemn saturated fat largely failed to demonstrate cardiovascular mortality reduction — and in several cases showed increased all-cause mortality in the seed-oil arms.
