Understanding the 'Wheat' in Subway's Bread
When ordering at Subway, many health-conscious consumers instinctively choose the 9-grain wheat bread, assuming it's a 100% whole-grain product. However, a closer look at the ingredients reveals a more nuanced picture. Unlike authentic whole wheat bread, which lists whole wheat flour as its first ingredient, Subway’s 9-grain wheat bread lists enriched white flour first. This is significant because the milling process that creates enriched flour strips away the nutrient-rich bran and germ, leaving only the starchy endosperm. While Subway adds some whole grain elements and seeds, the nutritional benefits are diminished compared to a genuinely whole-grain alternative.
Another key indicator of its processed nature is the addition of coloring. As revealed in a CBC Marketplace investigation, Subway adds caramel coloring to achieve its expected brown color, further masking its composition. This can be misleading for consumers who rely on color to gauge a bread's whole-grain content.
A Comparison of Subway's Breads
Subway's menu features various breads, each with a different nutritional profile. It's important to understand these differences to make an informed choice. The 'Hearty Multigrain' bread is a more recent addition and presents a better option for those seeking more fiber, although it is still a far cry from artisanal whole-grain bread.
Nutritional Comparison: 6-inch Subway Breads
| Attribute | 9-Grain Wheat Bread | Hearty Multigrain Bread | Artisan Italian (White) |
|---|---|---|---|
| Calories | ~210 | ~200 | ~200 |
| Protein | ~8g | ~9g | ~7g |
| Fiber | ~4g | ~3g | ~1g |
| Sodium | ~270mg | ~360mg | ~370mg |
| Added Sugar | ~4-5g | ~3g | ~2g |
As the table shows, the hearty multigrain bread often has a better fiber-to-sugar ratio than the 9-grain wheat, despite the latter's slightly higher calorie count in some regional formulations. However, both contain significant amounts of sodium and added sugar compared to what would be considered a truly healthy whole grain bread. The high sugar content in Subway's bread famously led an Irish court to rule that it was a sugary confectionery rather than a staple bread for taxation purposes.
The 'Processed Food' Elephant in the Room
The most significant concern regarding Subway's wheat bread is not simply its fiber content but its status as a processed food. The bread contains numerous ingredients beyond the basic flour, water, yeast, and salt found in traditional bread recipes. Historically, some formulations have included chemical dough conditioners like azodicarbonamide, which has been banned as a food additive in some countries. Although Subway has made reformulations, the complex list of ingredients points to a highly processed product designed for uniformity, shelf-life, and cost-effectiveness, rather than pure nutritional benefit.
This high degree of processing means the bread digests quickly, leading to potential blood sugar spikes—a common issue with refined grains. These spikes can lead to energy crashes and increased hunger, which undermines the goal of a healthy, filling meal. A truly wholesome whole-grain bread, with its high fiber content, digests slower, providing sustained energy and satiety.
Strategies for a Healthier Subway Sandwich
If your goal is to have the healthiest meal possible at Subway, focusing solely on the bread isn't enough. The fillings and condiments can dramatically alter the nutritional value.
Here is a list of choices to optimize your Subway experience:
- Prioritize lean proteins: Opt for lean meats like oven-roasted chicken breast or turkey breast over processed, higher-fat options.
- Maximize fresh vegetables: Load your sandwich with nutrient-packed vegetables like spinach, green peppers, cucumbers, and tomatoes.
- Use low-calorie condiments: Choose lighter dressings like balsamic vinegar or a small amount of mustard instead of creamy, high-calorie sauces.
- Consider a salad or wrap: For a lower-carb option, consider skipping the bread entirely and getting a salad. The newer, lavash-style wraps are also a lower-calorie alternative to the traditional wraps, though still higher in sodium than some breads.
- Stick to the 6-inch sub: Portion control is key. A 6-inch sub is often a more appropriate portion size than a foot-long, which can double your calories, sodium, and carbs.
Conclusion: A Balanced Perspective on Subway Bread
Ultimately, whether Subway wheat bread is healthy for you depends on the comparison. Compared to a double cheeseburger and fries from another fast-food chain, a Subway sandwich on wheat bread with fresh vegetables is likely a better option. However, when measured against genuine, unprocessed whole-grain bread, Subway's product falls short due to its primary ingredient being refined flour, high sodium levels, and added sugars. Consumers should be aware that the 'wheat' label is not a guarantee of a truly whole-grain product. Making a sandwich healthier involves a combination of choosing the best available bread option (like the Hearty Multigrain), and, most importantly, controlling fillings and condiments to keep overall nutritional values in check. The best choice is always one made with full information and awareness of your own dietary goals.
