Triglycerides are a type of fat found in your blood. They are the most common type of fat in the body and are used for energy. High levels of triglycerides in the blood can increase the risk of heart disease, stroke, and other health problems. Research in this area focuses on understanding the role of triglycerides in health and disease, as well as developing treatments and interventions to help lower triglyceride levels and reduce the risk of cardiovascular events. Studies may also investigate how lifestyle factors, such as diet and physical activity, can affect triglyceride levels.
