Health Benefits Of Tomato Rasam

3. Low In Calories
Tomato rasam is a low-calorie dish, making it an excellent option for those watching their weight. Its light and refreshing nature make it ideal for a guilt-free meal or snack.
4. Boosts Metabolism
The combination of spices in rasam can help boost metabolism, which may aid in weight loss. A faster metabolism also means your body can efficiently burn fat and convert food into energy, keeping you active throughout the day.

Why Is Sambar Considered Healthy?
1. Good Source Of Fibre
Sambar is made with a variety of vegetables and lentils, providing an excellent source of dietary fibre. A high-fibre diet like sambar helps promote regular bowel movements and prevents constipation.
2. Rich In Protein
The lentils used in sambar are a good source of protein, supporting muscle building and repair. This makes sambar an excellent option for vegetarians and vegans looking to meet their daily protein needs.
3. Packed With Vitamins And Minerals
Sambar contains a variety of vitamins and minerals, including vitamin A and potassium, which support healthy vision, immune function, and heart health.
4. Supports Healthy Gut Bacteria
The spices and lentils in sambar help support the growth of beneficial gut bacteria. Research by the National Institutes Of Health indicates that a diet rich in fibre and polyphenols can improve digestion and boost immunity.
Which Dish Is Lighter And Better For Weight Loss?
Tomato rasam is the lighter option and more effective for weight loss. Its low-calorie content, high water percentage, and metabolism-boosting spices make it ideal for slimming diets. Sambar, while highly nutritious, is more substantial due to its higher calorie and fibre content, making it better suited for a filling meal rather than a light snack.
