Fast food sandwiches can be tasty and convenient. Unfortunately, not all breakfast sandwiches are healthy. While some are made with health-conscious ingredients and fewer grams of sugar, others are loaded with carbs, fats, and staggering amounts of sodium. Fast food sandwiches run the gamut, so how do you tell healthy from unhealthy options?
To start, Jesse Feder, RDN, CPT to My Crohn’s and Colitis Team, shares that unhealthy breakfast sandwiches typically contain high amounts of saturated fat, sodium, calories, refined carbohydrates, and little to no fiber or nutrients. “The saturated fat in breakfast sandwiches usually comes from fatty meats, fried foods, and lots of cheese,” Feder shares.
Feder also points out that the bread used for unhealthy breakfast sandwiches is “usually refined white bread with little or no nutritional value.” “All of these things can contribute to excessive calorie intake, high blood pressure, increased levels of bad cholesterol, and other cardiovascular diseases,” Feder advises.
Luckily, it’s not all bad news – healthier options exist. Just be on the lookout for them (or modify the less healthy ones). For example, Mandy Tyler, M.Ed., RD, CSSD, LD, LAT sharing that you need to pay special attention to the type of bread used in a breakfast sandwich. “Select a sandwich made on an English muffin, bun, or whole-grain bread over a croissant or cookie to help reduce the amount of saturated fat in the sandwich,” says Tyler.
Feder adds that a healthy breakfast sandwich is usually made up of lean proteins (like egg whites and turkey bacon), healthy fats (including avocado and egg yolks), and whole grain carbohydrates. “A healthy breakfast sandwich will also include items that provide vitamins and minerals, such as a mix of different vegetables,” says Feder.
