The Claim

Smoking is associated with higher levels of C-reactive protein in adults, regardless of the presence or absence of age-related maculopathy.

Source: C-reactive protein and homocysteine are associated with dietary and behavioral risk factors for age-related macular degeneration.

In plain English

Adults who smoke have higher levels of C-reactive protein in their blood than non-smokers, whether or not they have age-related maculopathy.

See the scientific wording

Smoking is associated with higher levels of C-reactive protein in adults with or without age-related maculopathy, indicating that this behavioral risk factor for AMD is linked to systemic inflammation.

Why this might work

Chemicals in cigarette smoke damage cells throughout the body, which triggers a chain reaction that turns on a key inflammation switch inside immune cells. This switch causes the liver to release a protein called C-reactive protein into the blood.

What the research says

1 study

  1. Study: C-reactive protein and homocysteine are associated with dietary and behavioral risk factors for age-related macular degeneration.

    Smokers in the study had more of a body-wide inflammation marker called CRP, even if they didn’t have eye problems. So yes, smoking is linked to higher inflammation in the body.
