The fibre content can slow carbohydrate digestion and glucose absorption, potentially helping with better post-meal blood-glucose control.
6. Supports healthy weight management
Lotus stem is relatively low in calories while providing fibre, which can increase satiety and fullness.
7. Supports bone health
It provides minerals such as manganese, copper and phosphorus, which contribute to normal bone and connective-tissue metabolism.

Important point
The strongest evidence supports lotus stem as a nutritious vegetable, particularly as a source of fibre and micronutrients. Claims regarding anti-diabetic, anti-inflammatory or disease-preventive effects are promising but should not be interpreted as evidence that lotus stem can treat or cure diseases.
In short: Lotus stem can be a healthy addition to a balanced diet, particularly for fibre intake, antioxidant nutrition, digestive health and overall micronutrient intake.
