The Claim

In healthy adult men, a high-carbohydrate diet providing 52% of total calories leads to an initial sodium-retaining effect, which is accompanied by a compensatory reduction in plasma aldosterone levels by the second week, suggesting a counter-regulatory hormonal mechanism that may prevent prolonged sodium retention and subsequent elevation in blood pressure.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When healthy guys eat a diet high in carbs for a couple of weeks, their bodies initially hold onto more salt—but by week two, a key hormone that controls salt goes down, which might help stop blood pressure from rising.

See the scientific wording

In healthy adult men, the transient sodium-retaining effect of a high-carbohydrate diet (52% of calories) is accompanied by a compensatory decrease in plasma aldosterone levels by the second week, suggesting a counter-regulatory hormonal response that may prevent sustained sodium retention and blood pressure elevation.

What the research says

1 study
  1. Study: High-carbohydrate diet: antinatriuretic and blood pressure response in normal men.

    The study found that while eating lots of carbs causes the body to hold onto sodium at first, it quickly balances things out by lowering a hormone called aldosterone, which helps prevent long-term water retention and high blood pressure.
