Beef is not “all you need for better health”. It should be “part of the diet”, but it doesn’t cover ALL nutritional needs. An all beef diet induces negative calcium balance (as found in Stefansson and Anderson when they went on carnivore for 1 year in the Bellevue study). Additionally, beef (muscle meat) lacks magnesium, copper, thiamine, manganese, folate, boron, etc. The more restrictive a diet is, the greater the risk for nutrient deficiencies.
