The Claim

Among individuals with varying levels of cardiovascular fitness, the association between red and processed meat intake and cancer mortality is weaker in brisk walkers than in slow walkers, with a hazard ratio of 1.015 (95% CI: 0.990–1.040).

Source: Relevance of physical function in the association of red and processed meat intake with all-cause, cardiovascular, and cancer mortality.

In plain English

People who walk briskly show a slightly weaker link between eating red and processed meat and dying from cancer compared to those who walk slowly, based on a hazard ratio of 1.015.

See the scientific wording

The association between red and processed meat intake and cancer mortality is slightly attenuated in brisk walkers compared to slow walkers, with a hazard ratio of 1.015 (95% CI: 0.990–1.040), suggesting a potential protective effect of cardiovascular fitness on meat-related cancer risk.

Why this might work

People who walk briskly have muscles that use more oxygen and burn more fuel, which helps remove harmful chemicals from the blood faster and lowers chronic inflammation. This makes it harder for the damage from eating red and processed meat to lead to cancer.

  1. Study: Relevance of physical function in the association of red and processed meat intake with all-cause, cardiovascular, and cancer mortality.

    People who walk quickly may have a slightly smaller increase in cancer death risk from eating red or processed meat than people who walk slowly, though the difference is very small and not certain. The study found this pattern in a large group of people.
