Which is the healthiest bread to get at Subway?

3 min read

According to nutrition data updated in 2025, Subway's Hearty Multigrain bread stands out for its high fiber and protein content, making it a top contender when determining which is the healthiest bread to get at Subway. However, the best option depends on your specific health goals, as some breads may be lower in calories or sodium.

Quick Summary

This guide breaks down the nutritional content of Subway's most popular bread options, comparing their fiber, protein, calorie, and sodium levels. It helps you select the best bread for your dietary needs, whether you prioritize fiber, lower calories, or less added sugar.

Key Points

  • Hearty Multigrain is the most balanced choice: It offers the highest fiber and protein content, making it great for satiety and digestive health.

  • Flatbread is the lowest in calories: With only 140 calories per 6-inch serving, it's the ideal option for those watching their caloric intake.

  • Avoid sugary or high-sodium breads: Breads with added cheese or flavorings, such as Jalapeño Cheddar, are often higher in calories and sodium.

  • Check the added sugar content: Some supposedly 'healthier' whole-grain breads can contain added sugar, so review the nutrition information.

  • Consider the 'mini' size for portion control: For a lighter option, the mini-sized sandwiches or wraps can help reduce overall calorie and carb intake.

  • The wrap is not always the healthiest option: Despite popular belief, a standard wrap often contains more calories and sodium than a 6-inch multigrain bread sub.

  • Pair with healthy fillings: The final healthiness of your sandwich depends on all components. Load up on fresh vegetables and lean protein.

Navigating Subway's Bread Options for Better Nutrition

Choosing a healthier meal at a fast-food restaurant like Subway often comes down to making small, informed decisions. The bread you select is a foundational choice that significantly impacts your sandwich's overall nutritional profile. With various options, from whole-grain to artisan varieties, it can be tricky to know which is truly the healthiest. This article explores the nutritional details of Subway's breads to help you make the best choice for your dietary needs.

The Top Contenders: Hearty Multigrain vs. Flatbread

For most people, the decision will come down to Hearty Multigrain or Flatbread, each offering distinct benefits. Hearty Multigrain is the best option for those prioritizing fiber and whole grains, with 3 grams of fiber per 6-inch serving. This helps with digestion and keeps you feeling full longer. However, it does contain some added sugar. Flatbread, on the other hand, is the clear winner for those watching calories, as it is the lowest-calorie bread on the menu and contains no added sugar.

Nutritional Comparison of Key Breads

To help you decide, here is a comparison table of some of the most common 6-inch bread options at Subway, based on recent nutritional data:

Bread Type Calories Total Fat (g) Sodium (mg) Fiber (g) Protein (g) Added Sugar (g)
Hearty Multigrain 200 2 360 3 9 3
Flatbread 140 3 220 1 4 0
Artisan Italian 200 2 370 1 7 2
Honey Oat ~190 ~2 ~350 ~3 ~8 ~4
Jalapeño Cheddar 230 5 490 2 9 2

Beyond the Numbers: Other Considerations

While Hearty Multigrain and Flatbread are generally the top choices, other factors can influence your decision. For example, some locations may offer a Honey Oat bread that, while having a slightly higher sugar content, provides a similar level of fiber to Hearty Multigrain. The Artisan Italian is a suitable white bread option if you prefer a simpler flavor, as it is relatively low in fat and calories compared to some other choices. For those with dietary restrictions, it's worth noting that some locations offer a gluten-free bread, though cross-contamination is a risk. Wraps, often perceived as healthier, actually tend to be higher in both sodium and calories than a standard 6-inch sub, so it's essential to check the specific nutrition information.

Customizing Your Healthiest Subway Meal

Selecting the bread is just the first step in building a healthy sandwich. Your choice of fillings, sauces, and toppings can dramatically alter the final nutritional count. To maximize your sandwich's health benefits, follow these tips:

  • Choose Lean Proteins: Opt for options like oven-roasted turkey, rotisserie-style chicken, or roast beef.
  • Load Up on Veggies: Add extra vegetables like spinach, peppers, and cucumbers for more fiber and nutrients.
  • Be Mindful of Sauces: High-calorie sauces like ranch or creamy Italian can add significant calories and sugar. Stick with simpler dressings like vinegar or mustard.
  • Limit Processed Toppings: Cheese and extra sauces can increase sodium and saturated fat levels. Opt for a lower-sodium cheese like Swiss, or skip it entirely.

The Final Verdict: Which Bread Should You Choose?

For overall nutritional density, especially if you're looking for whole grains and fiber, the Hearty Multigrain is the best choice. It offers a solid balance of fiber and protein to keep you full. For those on a calorie-controlled diet or trying to minimize added sugars, the Flatbread is an excellent alternative, offering the fewest calories and no added sugar. Ultimately, the healthiest bread is the one that aligns best with your specific health priorities while serving as a foundation for a nutrient-packed meal.

By prioritizing whole grains, lean proteins, and plenty of fresh vegetables, a Subway sandwich can be part of a balanced diet. For comprehensive nutritional information, it's always best to consult Subway's official nutritional charts.

Conclusion: Your Healthiest Subway Choice

Choosing a healthy bread at Subway is a straightforward process once you know what to look for. While the Hearty Multigrain is the most nutrient-dense option, providing the most fiber and protein, the Flatbread offers the lowest calories and no added sugar. By comparing these options against your personal health goals, you can make an informed decision. Remember that a sandwich's healthiness also depends heavily on its fillings. To create a balanced and satisfying meal, choose lean meats, load up on vegetables, and use sauces sparingly.
