Source of validity: Scientific
Rating (out of 5): 5

Beef, particularly beef liver, is scientifically validated as supportive in the treatment of pernicious anemia due to its exceptionally high vitamin B12 content. Pernicious anemia is caused by a deficiency of vitamin B12, often due to impaired absorption rather than dietary lack. Historically, the discovery of beef liver’s effectiveness was a landmark in medical science: in the 1920s, George Minot and William Murphy demonstrated that feeding large amounts of raw liver to patients with pernicious anemia led to dramatic clinical improvement. This pivotal finding, for which they received the Nobel Prize in 1934, established that liver (a type of beef organ meat) contains a factor—later identified as vitamin B12—essential for red blood cell formation.

Today, vitamin B12 is routinely isolated and administered directly, but dietary sources such as beef remain important for maintaining adequate B12 levels, particularly in populations at risk for deficiency. Other cuts of beef contain variable amounts of B12, but organ meats like liver are especially potent. The use of beef and beef liver is thus both historically significant and scientifically validated; it is not merely traditional but grounded in robust clinical research. However, for individuals with pernicious anemia, B12 injections or high-dose oral supplements are preferred because the underlying issue is usually absorption, not intake.
