The Claim

In healthy young adults aged 18–45, consuming 200 grams of fructose daily with 3,900 mg of sodium for seven days increases 24-hour mean arterial blood pressure by approximately 3 mmHg (from 81 to 84 mmHg) compared to a diet with recommended sodium and fructose levels.

Cause and effect

In plain English

Consuming 200 grams of fructose and 3,900 mg of sodium daily for seven days raises average 24-hour blood pressure by about 3 mmHg in healthy adults aged 18–45 compared to diets with standard levels of these substances.

See the scientific wording

In healthy young adults aged 18–45, consuming 200 grams of fructose daily with 3,900 mg of sodium for seven days modestly increases 24-hour mean arterial blood pressure by approximately 3 mmHg (from 81 to 84 mmHg) compared to a diet with recommended sodium and fructose levels, suggesting a synergistic effect on blood pressure regulation.

Why this might work

When large amounts of fructose and salt are consumed together, the kidneys reabsorb more sodium instead of releasing it in urine. This causes fluid to build up in the bloodstream, increasing pressure inside the arteries. Fructose triggers a chain reaction in kidney cells that activates a sodium pump, while also preventing the body from normally turning off a hormone system that further boosts sodium retention.

  1. Study: The impact of dietary sodium and fructose on renal sodium handling and blood pressure in healthy adults

    When healthy young adults ate a lot of sugar and salt together for a week, their average blood pressure went up a little — but eating salt alone didn’t do it. This suggests sugar and salt work together to raise blood pressure.
