PUFAs are found in a variety of foods. Omega-3 fatty acids are abundant in fatty fish like salmon, mackerel, and sardines, as well as in flaxseeds, walnuts, and chia seeds. Omega-6 fatty acids are commonly found in vegetable oils such as soybean, corn, and sunflower oil. It's crucial to consume a balanced diet that includes both types of PUFAs.
