The Claim

In older adults with low-grade chronic inflammation, plasma phospholipid DHA content is inversely associated with body mass index (BMI), and BMI is positively associated with inflammatory markers including C-reactive protein (CRP) and interleukin-6 (IL-6), indicating that adiposity is a key driver of inflammation in this population.

In plain English

In older adults with low-grade chronic inflammation, higher body mass index is linked to lower levels of DHA in blood plasma and higher levels of inflammatory markers such as CRP and IL-6, suggesting that increased body fat is associated with greater inflammation.

See the scientific wording

In older adults with low-grade chronic inflammation, plasma phospholipid DHA content is inversely associated with body mass index (BMI), and BMI is positively associated with inflammatory markers including CRP and IL-6, suggesting adiposity may be a key driver of inflammation in this population.

Why this might work

When DHA, a fat from fish, is stored in cell membranes, it gets turned into special signaling molecules that calm down immune cells. These molecules block a key switch inside immune cells that turns on inflammation, leading to less production of inflammatory chemicals like IL-6 and CRP. Higher body fat reduces DHA levels in the blood, so this calming effect weakens, allowing inflammation to rise.

  1. Study: Associations between omega-3 fatty acid-derived lipid mediators and markers of inflammation in older subjects with low-grade chronic inflammation

    In older adults with long-term inflammation, people with more DHA (a healthy fat from fish) in their blood had lower levels of inflammation signals. This suggests that having less of this fat might be tied to more inflammation, which often comes with higher body fat.
