The Claim

In healthy young adults, replacing carbohydrates with dairy at breakfast reduces postprandial parathyroid hormone concentrations and bone resorption (measured as CTX-I) without altering bone formation (measured as P1NP).

How it works
1 study reviewed
In plain English

In healthy young adults, eating dairy instead of carbohydrates at breakfast lowers markers of bone breakdown without changing markers of bone building.

See the scientific wording

In healthy young adults, replacing carbohydrates with dairy at breakfast reduces postprandial parathyroid hormone and bone resorption (CTX-I) without affecting bone formation (P1NP), suggesting a transient suppression of bone breakdown that may support skeletal health.

Why this might work

When dairy is eaten for breakfast, calcium from the dairy enters the bloodstream, which tells the parathyroid gland to stop releasing a hormone that tells bones to break down. With less of this hormone, bone breakdown slows down, but bone building stays the same.

    When healthy young people eat dairy instead of carbs for breakfast, their bodies temporarily slow down the process of breaking down bone, but don’t change how fast they build new bone — which could help keep bones strong over time.
