The Claim

In healthy young adults aged 18–45, seven days of high sodium intake alone does not significantly alter 24-hour mean arterial blood pressure, whereas the combination of high sodium and high fructose intake induces a modest increase in 24-hour mean arterial blood pressure, demonstrating that fructose exposure converts individuals who are sodium-resistant into those who are sodium-sensitive.

How it works
1 study reviewed
In plain English

In healthy young adults, eating a lot of salt for seven days does not raise blood pressure, but adding a lot of fructose to the same diet causes a small increase in blood pressure, showing that fructose changes how the body responds to salt.

See the scientific wording

In healthy young adults aged 18–45, high sodium intake alone for seven days does not significantly alter 24-hour mean arterial blood pressure, but the addition of high fructose induces a modest increase, indicating that fructose converts sodium-resistant individuals into sodium-sensitive ones.

Why this might work

When a person eats a lot of sugar and salt together, the sugar causes the kidney to hold onto more salt instead of letting it leave in the urine. This extra salt pulls in more fluid, increasing the volume of blood in the vessels, which raises blood pressure. The sugar also stops the body from normally turning down a system that controls salt balance, making the kidney even more sensitive to signals that tell it to keep salt.

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

    Eating a lot of salt by itself doesn’t raise blood pressure in most young, healthy people—but when you add a lot of sugar, blood pressure goes up a little. This means sugar makes your body react to salt in a way it normally wouldn’t.
