Omega-3 and Omega-6 are both essential fatty acids, but they have different roles in the body. Omega-3s, found in fish, flaxseeds, and walnuts, are anti-inflammatory and support heart, brain, and joint health. Omega-6s, found in vegetable oils and processed foods, play a role in energy production and immune responses but can promote inflammation when consumed in excess. Maintaining a balanced ratio of Omega-3 to Omega-6 is key to overall health, as most modern diets tend to be too high in Omega-6.
