The Claim

In older adults aged 65 and above, a higher ratio of animal protein to plant protein intake is associated with higher bone mineral density at the spine and total body, independent of total protein intake.

Support is ahead, but a single strong opposing study can change this.

In plain English

Older adults who consume more animal protein relative to plant protein have higher bone mineral density in the spine and entire body, even when total protein intake is held constant.

See the scientific wording

In older adults aged 65 and above, a higher ratio of animal protein to plant protein intake is associated with higher bone mineral density at the spine and total body, independent of total protein intake.

Why this might work

Eating more animal protein than plant protein makes the body less acidic, which reduces the need to pull calcium from bones to balance blood pH. This lets more calcium stay in the bones and makes them denser.

1 study
  1. Study: Protein intake and bone mineral density: Cross‐sectional relationship and longitudinal effects in older adults

    In older adults, people who get more of their protein from meat, eggs, and dairy than from plants like beans and grains tend to have slightly stronger bones, even if they eat the same total amount of protein as others.
