The Claim

Higher intake of animal fat is associated with increased bone mineral density at multiple skeletal sites in both men and women over a six-year period.

In plain English

People who consume more animal fat have higher bone mineral density across multiple bones after six years compared to those who consume less.

See the scientific wording

Higher intake of animal fat is associated with increased bone mineral density at multiple skeletal sites in both men and women over six years, suggesting that dietary fat may play a protective role in bone health.

Why this might work

Eating more animal fat leads to higher levels of a growth hormone called IGF-I, which tells bone-building cells to make more bone. It also reduces the amount of calcium lost in urine, so more calcium stays in the bones to make them stronger.

  1. Study: Associations between Macronutrients Intake and Bone Mineral Density: A Longitudinal Analysis of the Health Workers Cohort Study Participants

    People who ate more animal fat instead of carbs had slightly stronger bones over six years, especially in the hip and spine, and this was true for both men and women.
