4 min read

According to nutrition data, green beans contain one of the lowest carbohydrate counts of any legume, with only around 2-4 grams of net carbs per cup. So, which bean has the lowest net carbs, and how do other popular varieties stack up for those following low-carb or ketogenic diets? This article delves into the nutritional facts to help you make informed choices.

Quick Summary

A nutritional guide identifying the beans with the lowest net carb count, featuring green beans and black soybeans. Includes comparison data for other legumes and tips for fitting them into a low-carb diet.

Key Points

  • Green Beans Offer Lowest Net Carbs: Green beans are a top choice with around 2-4 grams of net carbs per cup.

  • Black Soybeans are a Low-Carb Alternative: Black soybeans are an excellent substitute for traditional beans, containing as little as 2 grams of net carbs per half-cup.

  • Identify High-Carb Beans: Most common beans like pinto, kidney, and chickpeas are high in carbohydrates and should be limited on strict low-carb diets.

  • Focus on Net Carbs: Calculate net carbs by subtracting fiber from total carbohydrates, as fiber is not digested.

  • Utilize Portion Control and Substitution: Managing portion sizes or substituting higher-carb beans helps control carb intake.

  • Explore Other Low-Carb Legumes: Edamame, mung bean sprouts, and lupini beans are also viable low-carb options.

Low-Carb vs. High-Carb Beans

For those managing their carbohydrate intake, not all beans are created equal. The key metric to consider is 'net carbs,' which is calculated by subtracting fiber from the total carbohydrates. Fiber is a type of carbohydrate that the body does not digest and can lower a bean's impact on blood sugar. While many perceive beans as high-carb, certain types can be included in moderation on a low-carb or keto-friendly diet due to their high fiber content.

The Top Contenders for Lowest Net Carbs

When seeking the beans with the lowest net carbs, green beans and black soybeans are prominent options. Green beans, though botanically legumes, are often consumed like vegetables, contributing to their low carb count. Black soybeans offer a lower-carb alternative to traditional black beans.

Green Beans: A Leading Low-Carb Choice

Green beans, or snap beans, are a favored low-carb side. A one-cup serving of fresh green beans typically has around 7 grams of total carbs and 2.7 grams of fiber, resulting in approximately 4.3 grams of net carbs. This makes them a versatile low-carb option.

Black Soybeans: A Great Alternative

Black soybeans are another low-carb ally. A half-cup serving of canned black soybeans may contain as little as 1-2 grams of net carbs, although labeling can differ. They are also high in protein and can replace traditional black beans in many dishes.

Other Lower-Carb Options

Other legumes can be included in a lower-carb diet with careful portioning:

  • Edamame: Provides about 5-6 grams of net carbs per half-cup.
  • Lupini Beans: High in fiber and protein, with potentially as low as 1 gram of net carbs per serving.
  • Mung Bean Sprouts: The sprouted form is very low in net carbs and works well in salads and stir-fries.

Understanding Higher-Carb Beans

Certain beans have significantly higher net carb counts and are generally limited or avoided on most low-carb diets. These include:

  • Pinto Beans: Around 15 grams of net carbs per half-cup.
  • Kidney Beans: Approximately 13-14 grams of net carbs per half-cup.
  • Chickpeas: One of the highest net carb counts, about 17 grams per half-cup.

Comparison of Common Beans and Net Carbs

Here is a comparison of the net carb content for a half-cup serving of various beans. Values may vary.

Bean Type Total Carbs (g) Fiber (g) Net Carbs (g) Suitability for Low-Carb/Keto
Green Beans (Fresh) 3.5 1.8 1.7 Excellent
Black Soybeans (Canned) 8.0 6.0 2.0 Excellent
Edamame (Shelled) 7.0 4.0 3.0 Good (in moderation)
Mung Bean Sprouts 2.1 1.0 1.1 Excellent (sprouted form)
Lupini Beans 4.0 3.0 1.0 Excellent
Kidney Beans 20.0 7.0 13.0 High Carb (limit)
Pinto Beans 23.0 8.0 15.0 High Carb (limit)
Chickpeas 25.0 8.0 17.0 High Carb (limit)

Incorporating Beans into a Low-Carb Diet

Including beans in a low-carb diet is possible with careful planning and portion control. For higher-carb beans, use small amounts as a garnish or incorporate them into multi-serving recipes to distribute the net carbs. Substituting high-carb beans with low-carb options like black soybeans is also effective. Always check nutritional labels.

Conclusion

To determine which bean has the lowest net carbs, green beans and black soybeans are top choices due to their low net carb content, making them suitable for low-carb and keto diets. Green beans are consumed more like a vegetable, while black soybeans are a good substitute for higher-carb beans. With careful portioning and substitutions, you can incorporate various beans into your low-carb meal plan.
