The Core Difference: Preparation Method
The most significant factor determining whether lo mein or chow mein is healthier lies in how the noodles are prepared. Both dishes typically use Chinese egg noodles, but the cooking technique dramatically alters their texture and nutritional values. Understanding this fundamental distinction is the key to making a healthier choice. For lo mein, the noodles are boiled separately until cooked but still firm, then tossed with a thick, savory sauce, vegetables, and protein. In contrast, chow mein noodles are parboiled and then stir-fried until crispy, with the ingredients and a lighter sauce mixed in during the frying process.
Lo Mein: Tossed for Softness and Flavor
Translated as 'tossed noodles,' lo mein's defining characteristic is its soft, chewy texture, achieved by mixing fully cooked noodles with the other ingredients at the end of the cooking process.
- Noodles: Boiled and remain soft. This avoids the extra fat and calories associated with frying.
- Sauce: The dish is generously coated in a thick, rich sauce made from ingredients like soy sauce, oyster sauce, sesame oil, and cornstarch. While this provides a deep flavor, it is also the primary source of calories and, notably, high levels of sodium.
- Ingredients: Lo mein often includes a higher proportion of vegetables and protein, which are stir-fried separately before being combined with the noodles and sauce.
Chow Mein: Fried for a Crispy Crunch
Chow mein, or 'fried noodles,' is celebrated for its crispy texture. There are two main types: steamed chow mein, which is flash-fried before being tossed with ingredients, and crispy chow mein, where the noodles are fried into a 'pancake' before the other ingredients and sauce are added on top.
- Noodles: The frying process gives chow mein its signature crispiness but also significantly increases its fat and calorie content due to the oil absorbed during cooking.
- Sauce: It uses a minimal amount of sauce to avoid making the crispy noodles soggy. This results in less sodium from the sauce compared to lo mein, but the frying oil adds a different kind of calorie density.
- Ingredients: Crispy chow mein often features fewer vegetables compared to lo mein, with the focus remaining on the noodles.
A Comparison of Nutritional Content
While the base egg noodles have similar nutritional values, the cooking method makes a world of difference for the final dish. Below is a general nutritional comparison, though exact values vary widely by restaurant and recipe.
| Nutritional Factor | Typical Lo Mein (restaurant portion) | Typical Chow Mein (restaurant portion) |
|---|---|---|
| Calories | Often lower | Often higher |
| Fat Content | Generally lower (due to boiling) | Generally higher (due to frying) |
| Sodium | Often higher (due to generous sauce) | Often lower (due to minimal sauce) |
| Carbohydrates | Similar, but can vary by portion | Similar, but can vary by portion |
| Vegetables | Tends to include more | Tends to include less |
| Protein | Can be high with lean protein choices | Can be high, but meat may contain more fat |
Making a Healthier Choice
Choosing the healthier option ultimately depends on your nutritional priorities. If you are watching your fat and calorie intake, lo mein is generally the better starting point due to its boiled noodles. If sodium is your primary concern, chow mein with its minimal sauce may be preferable. However, both dishes can be modified to be much healthier with a few simple adjustments.
Tips for a Healthier Chinese Noodle Dish
- Ask for modifications. Request less oil for chow mein or less sauce for lo mein. Many restaurants are happy to accommodate such requests.
- Increase the vegetables. A higher ratio of vegetables to noodles and protein increases fiber and nutrient content.
- Choose lean proteins. Opt for chicken, shrimp, or tofu instead of fatty cuts of pork or beef.
- Consider steaming. Ask for your protein and vegetables to be steamed and the sauce served on the side, allowing you to control the amount you add.
- Look for 'Hong Kong-style.' Some menus specify 'Hong Kong-style chow mein,' which refers to the crispy, pan-fried noodles, while the soft, saucy version may just be labeled 'chow mein' in American Chinese cuisine. Knowing the regional differences can help you order exactly what you want.
Conclusion
In the showdown between lo mein and chow mein, lo mein often wins as the healthier option due to its non-fried preparation method, resulting in lower fat and calorie counts. However, it can be higher in sodium because of the sauce. For those who prefer the crispy texture of chow mein, controlling the portion and ordering it with less oil can mitigate its higher fat content. Ultimately, the healthiest version of either dish is a customized one: loaded with vegetables, lean protein, and a mindful amount of sauce. The decision rests on balancing your preference for a soft or crispy noodle with your specific dietary goals.

How to make a healthier version at home
Making lo mein or chow mein at home gives you complete control over the ingredients, from the amount of oil and salt to the types of vegetables used. For a healthier lo mein, cook noodles according to package directions, and then toss them with pre-sautéed vegetables, protein, and a homemade sauce made with low-sodium soy sauce, ginger, and garlic. For a healthier chow mein, lightly pan-fry parboiled noodles in a hot wok with just a small amount of oil, focusing on getting them crisp without deep-frying, and serve with lots of fresh, stir-fried vegetables.
Ingredient breakdown
Noodles
Both dishes use egg noodles. The difference lies in their state when cooked—soft and boiled for lo mein, or semi-cooked and then fried for chow mein. The nutritional impact comes primarily from the oil used for frying in chow mein, not the noodle itself.
Protein
The protein source is a major determinant of the dish's healthiness. Common additions include chicken, beef, shrimp, or tofu. Lean options like shrimp and chicken breast are lower in saturated fat than beef or pork.
Vegetables
Both dishes can be made healthier by adding more vegetables, which increase fiber, vitamins, and minerals. Common vegetables include cabbage, carrots, bell peppers, broccoli, and bok choy.
Sauce
This is where much of the sodium and sugar hide. Lo mein relies heavily on its sauce, while chow mein uses it more sparingly. Low-sodium soy sauce and homemade alternatives can significantly reduce sodium levels.
The takeaway experience vs. homemade
Takeout versions of lo mein and chow mein are often high in sodium, oil, and hidden sugars to maximize flavor. Making these dishes at home allows for customization and healthier ingredients, like less oil, low-sodium sauces, and a higher vegetable-to-noodle ratio.
