A Nutrient Powerhouse: What's in Lotus Root?
The lotus root is a low-calorie, fat-free option rich in carbohydrates and dietary fiber. A half-cup serving of cooked lotus root (approx. 60g) contains about 40 calories, 1g of protein, and nearly 2g of fiber. It's a good source of essential vitamins and minerals.
Vitamin and Mineral Content
Lotus root is rich in Vitamin C, a powerful antioxidant. It also contains B-vitamins, including B6 and thiamine. Key minerals include potassium, which helps regulate blood pressure, copper, important for brain function and bone strength, and iron, crucial for red blood cell production.
Primary Health Benefits of Eating Lotus Root
The compounds in lotus root offer several health advantages.
Supports Digestive Health
High in dietary fiber, lotus root promotes regular bowel movements and can help prevent constipation. This supports a healthy digestive tract and a balanced gut microbiome.
Boosts Heart Health
The potassium in lotus root can help lower blood pressure by balancing fluid levels. Its dietary fiber can help remove bad cholesterol, reducing the risk of heart disease. Pyridoxine (Vitamin B6) content also helps manage homocysteine levels, beneficial for heart health.
Strengthens Immunity
With its high concentration of Vitamin C, lotus root acts as an effective immune booster. Vitamin C is vital for immune system function and works as an antioxidant.
Aids in Weight Management
Lotus root is low in calories and high in fiber, which helps promote fullness and can aid in weight management. Its nutrients also support a healthy metabolism.
Promotes Glowing Skin and Brain Health
Vitamin C in lotus root supports collagen synthesis for healthy skin and acts as an antioxidant. Copper aids brain health by facilitating neural pathways, and polyphenolic compounds may improve neural function.
