Understanding the 'Low-Carb' Label
Many people on low-carb or ketogenic diets must carefully monitor their carbohydrate intake to maintain a state of ketosis. When evaluating vegetables, it's crucial to look at 'net carbs' rather than total carbohydrates. Net carbs are calculated by subtracting the dietary fiber from the total carbohydrates. Because fiber is a type of carbohydrate that the body cannot digest, it does not raise blood sugar levels and can be excluded from the total count.
Green Bean Net Carb Breakdown
Green beans have a favorable carbohydrate profile that makes them ideal for low-carb diets. A 100-gram serving of green beans contains approximately 7 grams of total carbohydrates. However, it also boasts about 3.4 grams of dietary fiber. This brings the net carb count down to just 3.6 grams, an amount that easily fits within the daily carb limits of most low-carb and keto plans. The edible pods of green beans are what make them significantly lower in carbs compared to many other legumes.
More Than Just a Low-Carb Vegetable
Beyond their low carb count, green beans are a nutritional powerhouse, providing a wealth of vitamins, minerals, and antioxidants that are beneficial for overall health.
Key nutritional benefits:
- Rich in Vitamins: They are an excellent source of vitamins C, K, and A. Vitamin C is a powerful antioxidant, Vitamin K is crucial for blood clotting, and Vitamin A supports healthy vision.
- High in Folate: A single cup provides a significant portion of the recommended daily intake of folate, a B vitamin essential for cell growth and DNA formation.
- Heart Health: The fiber content can help lower LDL ('bad') cholesterol, while potassium helps regulate blood pressure.
- Digestive Health: The fiber aids in digestion, promotes regular bowel movements, and supports a healthy gut microbiome.
- Low Glycemic Index: With a glycemic index (GI) of around 32, green beans have a minimal effect on blood sugar, which is particularly beneficial for those managing diabetes or following low-carb diets.
How Green Beans Compare to Other Low-Carb Vegetables
While many vegetables are low in carbs, green beans hold their own with a balanced nutritional profile. Here’s a quick comparison of the net carbs in a 100-gram serving of common vegetables:
| Vegetable | Total Carbs (g) | Fiber (g) | Net Carbs (g) | Key Nutrients |
|---|---|---|---|---|
| Green Beans | ~7 | ~3.4 | ~3.6 | Vitamins A, C, K, Folate |
| Broccoli | ~7 | ~2.6 | ~4.4 | Vitamins K, C, Folate |
| Cauliflower | ~5 | ~2 | ~3 | Vitamins K, C |
| Carrots (raw) | ~9.6 | ~2.8 | ~6.8 | Vitamin A, Biotin, Potassium |
As the table shows, green beans are a very competitive low-carb option, sitting comfortably alongside vegetables like cauliflower and broccoli. Their distinct flavor and texture also provide a welcome variety to a low-carb meal plan.

Important Considerations for Canned Green Beans
When using canned green beans, always check the ingredients label for hidden sugars or unwanted additives that can increase the carb count. Opt for brands with minimal ingredients or those explicitly labeled as low-carb or keto-friendly. Fresh or frozen green beans are often a safer bet, as you have full control over the ingredients used in preparation.
