The Potassium Content of Lima Beans
Lima beans are a nutritional powerhouse, known for their smooth, buttery texture and high potassium content. A single one-cup serving of cooked lima beans offers a substantial amount of nutrients. Here is what you can expect from a serving:
- Potassium: Around 955 mg, which is nearly 20% of the recommended daily intake.
- Fiber: With 13 grams per cup, lima beans provide excellent fiber content, which helps digestive health and helps manage cholesterol and blood sugar levels.
- Protein: Containing about 15 grams of plant-based protein per cup, lima beans are a useful source for vegetarians and vegans.
- Iron: A cup provides a considerable amount of iron, which is important for red blood cell production.
- Manganese: This mineral works as an antioxidant and is important in metabolism.
- Magnesium: This is essential for energy production and blood pressure regulation.
Comparing Lima Beans to Other High-Potassium Foods
While bananas are known for their potassium content, they are not the most concentrated source when compared to lima beans. Vegetables and legumes offer a higher density of this mineral. A cup of cooked lima beans contains more potassium than a medium banana, a cup of cooked spinach, or a medium baked potato.
Health Advantages of a Diet Rich in Potassium
The high potassium content in lima beans offers several significant health benefits. Potassium helps the body function correctly.
- Heart Health: Potassium helps control blood pressure by counteracting the effects of sodium, which helps reduce strain on the heart. A higher potassium intake is linked with a lower risk of cardiovascular disease and stroke.
- Bone Health: Potassium may improve bone health by neutralizing acids in the body that can leach calcium from bones. Diets rich in fruits and vegetables, which contain organic salts of potassium, can improve calcium balance.
- Kidney Health: Maintaining a healthy potassium intake is important for normal kidney function. In healthy individuals, the kidneys help regulate potassium levels by eliminating excess amounts.
