The Claim

In healthy young adults, replacing carbohydrates with dairy at breakfast results in reduced postprandial glucose levels without a significant change in postprandial insulin response, indicating that the glycemic effect of dairy is not mediated by insulin secretion.

How it works
1 study reviewed
In plain English

When healthy young adults eat dairy instead of carbohydrates for breakfast, their blood sugar drops but their insulin levels stay the same, meaning dairy lowers blood sugar through a process that does not involve increasing insulin.

See the scientific wording

In healthy young adults, replacing carbohydrates with dairy at breakfast does not significantly alter postprandial insulin response despite reducing glucose levels, suggesting that dairy’s glycemic benefit is mediated by mechanisms other than insulin secretion.

Why this might work

When dairy is eaten instead of carbs, proteins in the dairy break down into amino acids that signal the gut to release a hormone called GLP-1. This hormone slows down how fast food leaves the stomach and tells the pancreas to stop releasing glucagon, which reduces the amount of sugar released into the blood. This lowers blood sugar without needing more insulin.

    When people ate dairy instead of carbs for breakfast, their blood sugar dropped, but their insulin didn’t go up — meaning dairy lowers blood sugar in a different way than making the body release more insulin.
