How much polyinsaturated fat is in an egg yolk?

An egg yolk contains approximately 1.5 to 2 grams of polyunsaturated fat. The exact amount can vary slightly based on the size of the egg and the diet of the chicken. This fat is primarily composed of omega-3 and omega-6 fatty acids, which are essential for health. Overall, while egg yolks do contain polyunsaturated fats, they are not the primary source of fat in the yolk, which is mostly made up of monounsaturated and saturated fats.
