Identify one health benefit of omega-3 fatty acids.

Omega-3 fatty acids are essential fats that have garnered significant attention for their role in supporting heart health. They are known to lower triglyceride levels, reduce blood pressure, and decrease the risk of heart disease by reducing inflammation and improving endothelial function. This is particularly important as cardiovascular diseases are a leading cause of mortality globally, and incorporating omega-3s into the diet through sources like fish, flaxseeds, and walnuts can contribute to a healthier heart.

The other options, while beneficial in different contexts, do not accurately reflect the primary health benefit associated with omega-3 fatty acids. For instance, omega-3s do not increase muscle mass directly; instead, they are more linked to recovery post-exercise and reducing muscle inflammation. They also do not have a direct role in improving bone density, which is more influenced by factors like calcium and vitamin D intake. Furthermore, omega-3 fatty acids are not a cure for digestive disorders; while they can have a positive impact on gut health, they do not cure those conditions outright. Thus, the emphasis on supporting heart health stands out as a key benefit of omega-3 fatty acids.
