The omega‑6/omega‑3 ratio measures the balance between two essential fatty acids that influence inflammation and cellular function. A higher ratio—indicating relatively more omega‑6 than omega‑3—can suggest a diet rich in processed vegetable oils, excess linoleic acid intake, or insufficient consumption of fatty fish and other omega‑3 sources, and it is often associated with a pro‑inflammatory state that may contribute to cardiometabolic risk. Conversely, a lower ratio reflects greater omega‑3 availability, which is linked to anti‑inflammatory effects and may support heart health; this can be achieved through higher intake of omega‑3‑rich foods or supplementation. Factors such as dietary patterns, weight changes, and certain medications can shift the ratio, while the metric is applicable to all adults regardless of sex.
