In what form do omega-3 fatty acids primarily benefit health?

Omega-3 fatty acids primarily benefit health as precursors for hormones. These essential fatty acids play a critical role in the body by being converted into eicosanoids, which are signaling molecules that help regulate various physiological functions such as inflammation, blood clotting, and the immune response. This hormone-like effect of eicosanoids is significant because it can influence conditions such as heart disease, arthritis, and other inflammatory disorders.

While other options describe different macromolecules, they do not accurately represent the primary function of omega-3 fatty acids in health. Simple sugars, complex carbohydrates, and saturated fats serve different roles and do not encompass the unique benefits provided by omega-3 fatty acids in terms of hormone production and regulation. Thus, option B is the most accurate definition of how omega-3 fatty acids contribute to health.
