The Claim
In older adults aged 70 and above, an 8-week high-protein diet (1.2–1.5 g/kg/day) without omega-3 supplementation is associated with reduced gene expression of IL-1 receptor antagonist (IL1RN) in peripheral blood mononuclear cells.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 70 and older, following an 8-week high-protein diet without omega-3 supplements is associated with lower levels of IL1RN gene activity in immune cells from the blood.
See the scientific wording
In older adults aged 70 and above, an 8-week high-protein diet (1.2–1.5 g/kg/day) without omega-3 supplementation is associated with reduced gene expression of IL-1 receptor antagonist (IL1RN) in peripheral blood mononuclear cells, indicating a potential downregulation of anti-inflammatory signaling at the cellular level.
When older adults eat a high-protein diet, small protein fragments from dairy enter the bloodstream and bind to immune cells, turning down the activity of a key inflammation switch called NF-κB. This causes the cells to produce less of a protein that normally stops inflammation, leading to reduced anti-inflammatory signaling.
What the research says
1 studyIn older adults, eating more protein for eight weeks lowered the activity of a gene that helps calm inflammation, even without taking fish oil supplements. This suggests protein alone can affect how immune cells behave.
