Researchers have identified the molecular mechanism that makes omega-3 fats effective in reducing chronic inflammation and insulin resistance.
The scientists identified a key receptor on macrophages found in obese body fat. Omega-3 fats activate this macrophage receptor, resulting in anti-inflammatory effects and improved insulin sensitivity.
Eurekalert reports:
“Macrophages are specialized white blood cells that engulf and digest cellular debris and pathogens. Part of this immune system response involves the macrophages secreting cytokines and other proteins that cause inflammation ... Obese fat tissue contains lots of these macrophages producing lots of cytokines. The result can be chronic inflammation and rising insulin resistance”.
