Calorie Breakdown for 80g of Black Beans
The number of calories in 80g of black beans is highly dependent on their state—whether they are raw (dry), cooked, or canned. Understanding this distinction is key to accurate calorie tracking and meal planning. The water content is the primary factor that alters the caloric value by weight. When beans are cooked, they absorb a substantial amount of water, which increases their weight without adding calories, effectively lowering the calorie density per gram.
Raw vs. Cooked Black Beans
Raw, dry black beans are in their most concentrated form. An 80g serving of raw black beans is a dense, calorific portion that will expand significantly in volume and weight once cooked. For example, 80g of raw black beans contains around 273 calories. The same amount of raw beans will yield a much larger portion after cooking. Conversely, 80g of cooked black beans will have a much lower calorie count because the weight is predominantly water, not just the bean's solid components. For example, 80g of cooked black beans contains around 67 calories. This demonstrates how simply stating a calorie count for black beans without specifying their state can be misleading.
Nutrient Profile in 80g of Black Beans
Beyond calories, an 80g serving of black beans offers an impressive nutritional profile. They are a great source of plant-based protein and dietary fiber, which are vital for satiety, digestive health, and blood sugar control.
Macronutrient Breakdown (based on 80g raw black beans):
- Carbohydrates: 50g
- Protein: 17g
- Fat: 1g
- Fiber: 12g
This breakdown highlights their role as a high-fiber, high-protein food. For canned or cooked beans, these numbers will change relative to the lower caloric total for an 80g serving, but the overall nutritional density per calorie remains high.
Cooking Methods and Calorie Changes
The way black beans are prepared can influence the final calorie count and nutritional content, particularly concerning additives. While the beans themselves remain consistent, what you add to them can significantly alter their nutritional value.
- Boiling at home: Cooking dried black beans in plain water does not add any calories. The calorie count per gram simply decreases as the beans absorb water and swell. You can control the amount of sodium by avoiding salt or adding a small amount to taste.
- Canned beans: Canned black beans are a convenient option, but they often contain added sodium. However, rinsing and draining canned beans can significantly reduce their sodium content. A typical 80g serving of canned, drained black beans contains around 73 calories and a small amount of sodium.
- Refried beans: Some products, like refried black beans, are mixed with other ingredients such as oil or lard, which increases their fat and calorie content. For example, some brands of refried beans contain added fats and sodium that boost their caloric value.
Comparison Table: 80g of Black Beans by Preparation Type
| Preparation Type | Calories (Approx.) | Protein (Approx.) | Fiber (Approx.) | Notes |
|---|---|---|---|---|
| Raw, Dry | 273 | 17g | 12g | Calorie-dense due to low water content. |
| Cooked (Boiled) | 67-115 | 5-8g | 6-8g | Weight includes absorbed water; lower calorie density. |
| Canned (Drained) | 73 | 5g | 6g | Convenient but may contain added sodium; rinse to reduce sodium. |
Health Benefits of Adding Black Beans to Your Diet
Including black beans in your meals is a great way to boost your nutritional intake. Here are some of their key health benefits:
- High in Antioxidants: Black beans are rich in anthocyanins and flavonoids, which have antioxidant properties that help protect cells from damage and may lower the risk of chronic diseases such as heart disease and cancer.
- Supports Heart Health: The soluble fiber in black beans helps lower cholesterol levels, and their potassium, magnesium, and folate content can help regulate blood pressure, contributing to better cardiovascular health.
- Aids in Weight Management: The high fiber and protein content promotes satiety, helping you feel fuller for longer and potentially reducing overall calorie intake. The slow-digesting carbohydrates also help manage blood sugar levels, preventing spikes.
- Boosts Digestive Health: Both soluble and insoluble fiber in black beans support a healthy digestive system. The resistant starch acts as a prebiotic, feeding beneficial gut bacteria and aiding gut health.
Conclusion
The number of calories in 80g of black beans is not a single, fixed number. It varies significantly based on whether the beans are raw, cooked, or canned. A small 80g serving of dry black beans is much more calorie-dense at around 273 calories, while the same weight of cooked beans is far lower at approximately 67-73 calories. For accurate nutritional information, it is essential to specify the bean's state. Incorporating black beans into your diet is an excellent way to get a nutrient-dense food rich in fiber, protein, and antioxidants, offering numerous health benefits for heart health, weight management, and digestion.

How to Calculate Black Bean Calories Accurately
To ensure you are tracking your intake correctly, always use the nutritional information for the specific preparation method you are using. For dried beans, a good practice is to weigh them dry, cook them, and then divide the cooked portion into desired serving sizes. For canned beans, always drain and rinse to control the sodium and use drained weight for calculation. Food tracking apps or websites can be helpful, but double-check that they specify raw, cooked, or canned beans.
