Is Soup High in Fiber?

Soup can be high in fiber if it has lots of high fiber vegetables or beans in it. The Mayo Clinic recommends getting between 21-25 grams of fiber daily for women and 30 to 38 grams of fiber for men. The average vegetable has around 4-5 grams per cup. A cup of lentils contains 15.5 grams of fiber. Choose a soup with lots of vegetables and beans for a high fiber soup option.

How do you make a Soup High Fiber?

Soup can be made high fiber with the addition of both beans and vegetables. Beans and legumes have the highest fiber content, making them a great ingredients to easily increase fiber. Split peas, lentils, and black beans all have around 15 grams of fiber per cup. Vegetable soup can be made high fiber by adding in beans or lentils into it.

Does Lentil Soup have Fiber?

Lentil soup has around 12 grams of fiber per cup of soup. You can increase the fiber in lentil soup by adding in extra vegetables or beans. For this detox lentil soup, we added in high fiber foods like dates, pumpkin seeds, and kale. Lentil soup is already a great source of fiber by itself, add in some extra high fiber vegetables and beans to make it even better.

What are the benefits of Lentil Soup?

The largest benefit of lentil soup is the fiber content. However, that is not the only benefit that lentil soup offers. This healthy soup is high in protein, Iron, and folic acid. Lentil soup is also a great source of magnesium and offers a good amount of calcium. Homemade lentil soup is an incredibly healthy meal to make.

Cooking Tips:

All the ingredients in this soup work together to make a wonderful flavor blend. Feel free to adjust the amounts you use to tweak this soup to your taste.


This is a unique soup with a wonderfully different flavor profile. I really enjoy it and it is well reviewed. I hope you will try it as written at least once before choosing to tweak this recipe. With that said, Here are some notes on substitutions and adjustments.

The nutritional profile will suffer if you choose to opt out of the ginger, carrots, kale and garlic. They all offer amazing health benefits.

If you don’t have one of the ingredients for this soup here are some ideas for you.

  • Lentils come in different varieties and colors. The tiny black lentils, fast cooking orange or red lentil and yellow. You may need to adjust the cooking time of your lentil depending on which variety you have on hand. ALL these lentils will make great detox soup for you. Just remember to soak your lentils ahead and drain them before cooking.
  • You can use maple syrup instead of the dates.
  • You can choose whatever peppers you prefer for this soup. I use them raw for the best flavor and nutrient gain. You can also add more peppers or just use one to your taste.
  • Sesame oil does add an particular flavor you will notice. Hot sesame oil also adds a spicy element. You can choose avocado oil or coconut oil for this recipe if you don’t enjoy sesame oil.
  • This also applies to the seasonings. Adjust them to suit yourself.

Instead of the lentils, i add chickpea flour after the ingredients are cooked and blended. I make a pouring consistency batter and then make pancakes.
