Omega-3 fatty acids have anti-inflammatory effects, and in a clinical trial of lung cancer patients, omega-3 supplementation significantly reduced the levels of inflammatory factors such as CRP and IL-6 in the blood of patients during chemotherapy while improving body weight, albumin, and other nutritional indicators, which helped alleviate the systemic inflammatory response and malnutrition caused by chemotherapy (63). The gene discussed is CRP; the disease is lung cancer.
