The Claim

High carbohydrate intake leads to increased sodium retention in the body, which contributes to elevated blood pressure levels.

What the research says

Supports is higher

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

High carbohydrate intake causes sodium retention in the body, contributing to increased blood pressure.

What the research says

3 studies

  1. Study: Gender-specific association between carbohydrate consumption and blood pressure in Chinese adults

    The study found that women who ate more carbohydrates tended to have higher blood pressure, which fits with the idea that carbs might affect blood pressure, possibly through salt balance.

  2. Study: Carbohydrate hastens hypervolemia achieved through ingestion of aqueous sodium solution in resting euhydrated humans

    The study found that adding carbs to a salty drink made the body hold onto more fluid faster, which can lead to higher blood pressure. This supports the idea that carbs can increase sodium retention.
