Key Nutritional Components
Let’s break down what’s actually in a Filet-O-Fish, beyond just the fish. It’s easy to think of it as just a sandwich, but there are a few key players when it comes to its nutritional makeup. We’re talking about the protein, the carbs, and the fats, and how they all add up.
Filet O Fish Protein Content
Protein is a big one, right? It’s what helps you feel full. The Filet-O-Fish packs a decent amount of protein, mostly coming from that fish patty. It’s not a steak, obviously, but it contributes to your daily protein needs. For a standard serving, you’re looking at around 15 grams of protein. That’s pretty good for a fast-food fish sandwich. It’s a solid chunk of the recommended daily intake, which is helpful if you’re trying to keep track of that. This protein helps build and repair tissues, so it’s doing more than just filling you up.

You’ve got fats from the fish itself, the oil used for frying, the cheese, and the tartar sauce. The total fat content is around 21 grams. A good chunk of that is saturated fat, which is something to be mindful of. Remember, fats are necessary, but it’s about balance.
Vitamins and Minerals in Filet O Fish
While it’s not exactly a health food powerhouse, the Filet-O-Fish does offer some vitamins and minerals. The fish itself provides some omega-3 fatty acids, which are good fats. You’ll also find smaller amounts of things like Vitamin A, calcium, and iron, mostly from the bun, cheese, and fish. For instance, the zinc content is around 0.78 mg, which is about 7% of your daily value. It’s not a huge amount, but it’s there. These micronutrients play various roles in keeping your body running smoothly. It’s interesting to see what little bits of goodness can be found even in a fast-food item. The Filet-O-Fish meal offers a bit of everything, but it’s important to see the whole picture.

Let’s break down what actually goes into a Filet-O-Fish. It’s not just a fish sandwich; it’s a specific combination of ingredients that give it that familiar taste. Understanding these components can help you make more informed choices about what you’re eating.
The Fish Fillet Ingredients
The star of the show, the fish fillet, is made from Alaska Pollock. It’s coated in toasted wheat crumbs and fried in a blend of vegetable oils, including canola, corn, soybean, and hydrogenated soybean oil. You’ll also find modified corn starch, flour, colorings like paprika and turmeric, cellulose gum, salt, and spices in the coating. It’s important to note that this part contains wheat and fish.
Bun and Tartar Sauce Components
The bun is a standard soft, steamed bun made from unbleached enriched wheat flour. It also contains sugar, yeast, vegetable oil, salt, and potato flour. Additives like monoglycerides, calcium propionate, and potentially wheat gluten, enzymes, ascorbic acid, and others are used for texture and preservation. The tartar sauce is a mix of soybean oil, relish (which includes pickles, vinegar, and spices), liquid egg yolk, onion, sugar, and salt. It also contains mustard flour and preservatives like potassium sorbate and xanthan gum. This section contains egg and mustard.
Processed Cheese Slice Ingredients
That melty slice of cheese isn’t just any cheese. It’s a processed cheese slice made primarily from cheese (which includes milk and bacterial culture), modified milk ingredients, and salt. The exact composition can vary slightly, but it’s designed to melt well on the sandwich.
