Field beans (Vicia faba L.) are nutrient-dense legumes that provide excellent nutritional value. Research from ScienceDirect and studies from the Journal of Animal and Feed Sciences demonstrate that field beans offer unique nutritional advantages due to their high protein content and complete amino acid profile.

Regular Field Beans (per 100g raw):
• Calories: 341 kcal
• Protein: 24.4g (complete amino acid profile)
• Carbohydrates: 58.3g (complex carbohydrates)
• Fat: 1.5g (low fat content)
• Fiber: 25.0g (exceptional fiber content)
• Iron: 6.7mg (excellent iron source)

Cooked Field Beans (per 100g):
• Calories: 110 kcal (water absorption reduces density)
• Protein: 7.6g (retains protein quality)
• Carbohydrates: 19.7g (easily digestible)
• Fat: 0.4g (minimal fat)
• Fiber: 8.1g (supports digestion)
• Iron: 2.1mg (good iron content)

Field Bean Serving Size Guidelines

Standard Serving: One cup of cooked field beans (180g) provides about 220 calories and serves as an excellent source of plant-based protein and fiber for healthy meal planning.

Common Serving Sizes:
• 1 tablespoon raw (15g): 51 calories
• 1/4 cup raw (40g): 137 calories
• 1/2 cup raw (80g): 273 calories
• 1 cup cooked (180g): 220 calories
• 100g raw: 341 calories

Portion Control: Field beans are calorie-dense and provide sustained energy due to their high fiber and protein content. Plan your daily macros accordingly to optimize your nutritional intake.

Field Bean Nutritional Profile

Field beans are exceptional nutritional powerhouses that provide complete nutrition for overall health. Studies from Taylor & Francis demonstrate that field beans offer unique health benefits due to their high protein and fiber content.

Key Nutrients (per 100g raw field beans):
• Complete Protein: 24.4g (contains all essential amino acids)
• Complex Carbohydrates: 58.3g (sustained energy release)
• Dietary Fiber: 25.0g (highest among legumes)
• Iron: 6.7mg (significant plant-based iron source, non-heme form)
• Folate: 423mcg (106% DV – supports DNA synthesis)
• Manganese: 1.6mg (supports bone health)

Protein Digestibility: Field beans have a protein digestibility-corrected amino acid score (PDCAAS) of 0.69, which is good for a plant-based protein source. The protein is limiting in methionine and cysteine but provides excellent complementary nutrition when combined with grains or other protein sources. Calculate your daily protein needs to optimize your field bean consumption.

Tannin Content & Nutritional Considerations

Proanthocyanidin Content: Field beans naturally contain condensed tannins that can affect nutrient absorption. Research shows that cooking methods and variety selection can significantly reduce tannin levels while preserving nutritional benefits.

Low-Tannin Varieties: Modern low-tannin field bean varieties provide superior nutritional bioavailability and are easier to digest without compromising protein quality.

Cooking Impact: Proper soaking and cooking can reduce tannin content by up to 80% while maintaining the beneficial nutrients. Use our BMI calculator to assess your overall health status.
