Which food item is a primary source of omega-6 fatty acids?

Walnuts are indeed a primary source of omega-6 fatty acids. Omega-6 fatty acids are essential fats that the body cannot produce on its own, so they must be obtained through diet. Walnuts are particularly high in a type of omega-6 fatty acid known as linoleic acid, making them an excellent choice for those looking to increase their omega-6 intake.

In addition to being a rich source of fatty acids, walnuts also provide other beneficial nutrients, including protein, fiber, vitamins, and minerals. These attributes contribute to their reputation as a heart-healthy food that can support overall nutrition.

While options like sardines, chicken, and whole grain bread contain some fat, they are not as concentrated in omega-6 fatty acids as walnuts. Sardines primarily offer omega-3 fatty acids, chicken is a source of various types of fats but with a lesser concentration of omega-6, and whole grain bread provides carbohydrates and some healthy fats but lacks significant amounts of omega-6. Thus, walnuts stand out as a key dietary source of omega-6 fatty acids.
