People who follow a pescatarian diet have a lower rate of death from any cause compared to people who eat meat and fish.
Mechanism
Synthesis from 1 study
Eating fish instead of red meat lowers bad fats and swelling in the body, which keeps the heart and blood vessels healthier. This directly reduces the chance of dying from chronic diseases.
Most probable mechanism
Eating fish instead of red meat lowers harmful fats in the blood and reduces swelling in the body, which keeps blood vessels and organs healthier and prevents early death.
Increased intake of omega-3 fatty acids from fish directly reduces the production of pro-inflammatory lipid mediators in immune cells
Lower consumption of red and processed meats decreases saturated fat intake, reducing hepatic synthesis of very-low-density lipoprotein and lowering circulating triglycerides
Reduced systemic inflammation and improved lipid profile decrease endothelial dysfunction and arterial plaque formation
Lower incidence of cardiovascular disease, metabolic dysfunction, and chronic organ damage reduces the risk of all-cause mortality
