Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are types of healthy fats found in fish. They may compete with each other in our bodies, affecting how our cells work and how inflammation is controlled. EPA and DHA might fight for space in our cell membranes, which could change how our bodies make substances that affect inflammation. They also have different effects on the structure of our cell membranes, which could impact how cells communicate. DHA can also lower the amount of EPA in our cell membranes. This competition between EPA and DHA could be important for our health and might change how we should eat to stay healthy.
