Beans are a nutritious food packed with protein, fiber, vitamins, and minerals. However, if you’re watching your carbohydrate intake or following a low carb diet, you may wonder whether beans fit into your eating plan.
The short answer is yes, beans are relatively high in carbohydrates. However, they also contain significant amounts of fiber and protein, which can affect how your body processes these carbs and may offer several health benefits.
This comprehensive guide will help you understand the carbohydrate content of various beans, their nutritional value, and how to incorporate them into your diet based on your health goals.
Understanding Carbohydrates in Beans
Beans and legumes are considered complex carbohydrates, meaning they contain longer chains of sugar molecules that take more time for your body to break down compared to simple carbs.
Most beans contain both total carbohydrates and dietary fiber. When calculating “net carbs” (total carbs minus fiber), the number becomes more favorable for those monitoring their carb intake, as fiber doesn’t significantly impact blood sugar levels the same way other carbohydrates do.
The carbohydrate content in beans varies by type, but generally, one cup of cooked beans contains between 25-45 grams of total carbohydrates.
Carb Content in Different Types of Beans
Here’s a detailed breakdown of the carbohydrate content in common bean varieties per 1 cup (approximately 160-200 grams) of cooked beans:

Green beans are significantly lower in carbs than dried beans. One cup (100 grams) of cooked green beans contains approximately 7 grams of total carbs and 3 grams of fiber, resulting in just 4 grams of net carbs.
Black Soybeans
Black soybeans are among the lowest-carb bean options. One cup of cooked black soybeans contains about 8 grams of total carbs, 7 grams of fiber, and only 1 gram of net carbs, making them suitable for even strict low carb diets.
Edamame (Young Soybeans)
One cup of cooked edamame contains approximately 14 grams of total carbs, 8 grams of fiber, and 6 grams of net carbs, along with 17 grams of protein.
Nutritional Benefits of Beans
Despite being higher in carbohydrates, beans offer numerous nutritional benefits that make them a valuable addition to many diets:
High in Protein
Beans are an excellent plant-based protein source, with most varieties providing 15-18 grams of protein per cup. This makes them particularly valuable for vegetarians, vegans, and those looking to reduce meat consumption.
Rich in Fiber
The high fiber content in beans supports digestive health, helps maintain stable blood sugar levels, promotes feelings of fullness, and may aid in weight management. Most beans provide 11-19 grams of fiber per cup.
Packed with Essential Nutrients
Beans contain important vitamins and minerals including:
- Folate (vitamin B9)
- Iron
- Magnesium
- Potassium
- Zinc
- B vitamins
- Antioxidants
Support Heart Health
Regular consumption of beans has been linked to improved heart health. The soluble fiber in beans can help reduce cholesterol levels, while their potassium content supports healthy blood pressure.
May Reduce Disease Risk
Studies suggest that eating beans regularly may help reduce the risk of heart disease, type 2 diabetes, and certain types of cancer due to their nutrient profile and anti-inflammatory properties.
Can You Eat Beans on a Low Carb Diet?
Whether beans fit into a low carb diet depends on your specific carbohydrate goals and the type of low carb plan you’re following.
Ketogenic Diet (20-50 grams of carbs daily)
Most traditional beans are too high in carbs for a strict ketogenic diet. However, you may be able to include small portions of lower-carb options like black soybeans, edamame, or green beans.
Moderate Low Carb Diet (50-100 grams of carbs daily)
On a moderate low carb diet, you can typically include small to moderate portions of beans. A half-cup serving of most beans would provide 12-22 grams of net carbs, which can fit into this carb range when balanced with other foods.
Liberal Low Carb Diet (100-130 grams of carbs daily)
With this higher carb allowance, you can more easily incorporate beans into your meals. A full cup serving can fit comfortably within your daily carb limit while providing valuable nutrients.
Tips for Including Beans in a Lower Carb Diet
If you want to enjoy beans while managing your carb intake, consider these strategies:
Watch Portion Sizes
Instead of a full cup, try using 1/4 to 1/2 cup portions of beans in salads, soups, or side dishes. This reduces carb intake while still providing nutritional benefits.
Choose Lower Carb Varieties
Opt for black soybeans, edamame, or green beans when possible. These varieties provide protein and fiber with fewer net carbs.
Balance with Low Carb Foods
Combine beans with non-starchy vegetables, healthy fats, and protein sources to create balanced meals that won’t spike your blood sugar.
Account for Total Daily Carbs
Plan your meals to ensure beans fit within your overall daily carb budget. If you include beans at one meal, reduce carbs from other sources.
Focus on Whole Beans
Avoid refried beans with added fats and oils, canned beans with added sugars, or sweetened baked beans, which contain more carbs and less nutritional value.
Beans vs. Other Protein Sources
Comparing beans to other protein sources can help you make informed dietary choices:
Beans vs. Meat
Animal proteins like chicken, beef, and fish contain virtually no carbohydrates but also lack the fiber found in beans. Beans offer a more economical protein option with additional nutrients but higher carbs.
Beans vs. Tofu
Tofu is lower in carbs than most beans (3 grams per cup) while providing similar protein content, making it a better option for strict low carb diets.
Beans vs. Nuts
Nuts generally contain fewer carbs than beans while providing healthy fats and protein. However, beans are more affordable and provide more fiber per serving.
How Beans Affect Blood Sugar
Despite their carbohydrate content, beans have a relatively low glycemic index (GI), typically ranging from 20-40. This means they cause a slower, more gradual rise in blood sugar compared to refined carbohydrates.
The high fiber and protein content in beans helps slow digestion and the absorption of glucose into the bloodstream. This can help prevent blood sugar spikes and crashes, making beans a reasonable choice even for people managing diabetes, though portion control remains important.
If you have diabetes or blood sugar concerns, consult with your healthcare provider or a registered dietitian about appropriate portion sizes and how beans fit into your meal plan.
Preparing Beans for Better Digestion
Some people experience digestive discomfort when eating beans. Here are tips to improve digestibility:
Soak Dried Beans
Soaking dried beans for 8-12 hours before cooking can help reduce compounds that cause gas and bloating.
Cook Thoroughly
Ensure beans are fully cooked, as undercooked beans are harder to digest and may cause discomfort.
Start with Small Portions
If you’re not used to eating beans regularly, introduce them gradually to allow your digestive system to adjust.
Rinse Canned Beans
Rinsing canned beans removes excess sodium and some of the oligosaccharides that can cause gas.
Add Digestive Aids
Cooking beans with herbs like bay leaves, cumin, or ginger may help improve digestion.
Healthy Ways to Enjoy Beans
Here are nutritious ways to incorporate beans into your diet while managing carb intake:
- Add a quarter cup of black beans to salads for extra protein and fiber
- Use chickpeas to make homemade hummus with plenty of vegetables for dipping
- Include green beans as a low carb side vegetable
- Add lentils to soups and stews in smaller portions
- Snack on roasted edamame for a protein-rich treat
- Use black soybeans in chili recipes as a lower-carb bean option
- Mix beans with cauliflower rice to reduce overall carb content while adding nutrition
When to Limit or Avoid Beans
While beans are nutritious for most people, certain situations may require limiting or avoiding them:
Very Low Carb or Ketogenic Diets
If you’re following a strict ketogenic diet with a very low daily carb limit (20-30 grams), most traditional beans won’t fit into your plan except in very small amounts.
Digestive Conditions
People with certain digestive conditions like irritable bowel syndrome (IBS) may need to limit high-FODMAP foods, including some types of beans.
Allergies or Sensitivities
Though rare, some people have allergies or sensitivities to legumes and should avoid them.
Certain Medications
If you’re taking specific medications, particularly MAO inhibitors, consult your healthcare provider about bean consumption, as they contain tyramine which may interact with these medications.
