McDonald’s Filet-O-Fish Sandwich

The Filet-O-Fish was the first fish sandwich ever offered by a fast-food chain. It has been on the McDonald’s menu since 1962. And its ingredients have essentially remained the same since its inception.

The fish sandwich is one of the chain’s most requested menu items and, it’s also the perfect choice for the Lenten season. Let’s take a look at its nutritional profile.

McDonald’s Fish Sandwich — better known as Filet-O-Fish (or Fish-O-Filet) — is a 390 calorie menu item that is both filling and satisfying, and it has a decent amount of protein.

The sandwich has 19 grams of fat, 38 grams of carbs, and 560 milligrams of sodium. Those nutritional numbers make it one of the healthiest choices on the restaurant’s menu.

The sandwich’s ingredients include a wild-caught Alaskan Pollock, breaded and deep fried in vegetable oil, and topped with melted American cheese and tartar sauce on a warm, soft bun.

You can actually make it healthier by doing a few simple adjustments like dropping the cheese, the sauce, and maybe even the bun depending on your needs. I will refer to more specifics below.
