What are butter beans?
Butter beans, scientifically known as Phaseolus lunatus, are a type of legume also widely referred to as lima beans. They are characterized by their creamy, starchy texture and mild flavor. They are a staple in many cuisines, prized for their versatility in a wide range of dishes, including soups, salads, and casseroles. Available dried, canned, or frozen, their nutritional profile is a key reason for their popularity among health-conscious consumers. While they offer substantial nutritional benefits regardless of the preparation, the specific values, particularly sodium content, can vary between dried beans and those that are canned.
Detailed nutritional breakdown of cooked butter beans
The nutritional composition of cooked butter beans per 100g showcases a nutrient-dense food that is both low in fat and cholesterol-free. The values can vary slightly depending on the preparation method and source, but general figures provide a clear picture of their health benefits.
- Calories: 100 grams of cooked butter beans provide approximately 115 calories, making them a relatively low-energy-dense food that promotes satiety.
- Protein: They offer a solid source of plant-based protein, with about 7.8 grams per 100g. This is crucial for muscle repair, tissue regeneration, and overall bodily function, particularly for vegetarians and vegans.
- Carbohydrates: With roughly 20.9 grams of carbohydrates per 100g, butter beans provide long-lasting energy due to their complex carbohydrate structure.
- Fiber: A single 100g serving contains about 7 grams of dietary fiber. This high fiber content includes both soluble and insoluble types, which aids digestion, promotes fullness, and can help regulate blood sugar and cholesterol levels.
- Fat: Butter beans are naturally low in fat, with only about 0.38 grams per 100g, and contain virtually no saturated fat.
Key vitamins and minerals
Beyond the macronutrients, butter beans are an excellent source of several vital vitamins and minerals.
- Folate (Vitamin B9): Essential for red blood cell formation and DNA synthesis, a 100g serving contributes significantly to daily folate needs.
- Iron: The iron content helps prevent anemia by assisting in oxygen transport throughout the body. Plant-based iron is best absorbed when consumed with a source of Vitamin C.
- Potassium: Crucial for maintaining fluid balance, nerve function, and supporting heart health, butter beans contain significant amounts of potassium.
- Magnesium: This mineral is involved in hundreds of biochemical reactions in the body, including muscle and nerve function, and energy production.
- Zinc: Important for immune function and cellular metabolism, butter beans provide a valuable source of this trace mineral.
- Manganese: Another trace mineral, manganese assists in metabolizing carbohydrates and proteins.
