Health benefits of Jerusalem artichoke

Acts as a prebiotic

It is loaded with inulin, a type of fiber that although not digestible by humans in the gastrointestinal tract, acts as a prebiotic in the digestive tract, where your bacteria uses it to prosper. In your gut, this starch is converted into short-chain fatty acids which are converted to ketones. Furthermore, when inulin is combined with liquid, due to its chemical composition it forms a creamy gel that’s good for relieving constipation.

Prevents iron-anemia

Iron is a crucial dietary mineral needed to help our red blood cells deliver the vital oxygen to the body. Iron also plays an essential role in energy creation, muscle function, and brain development. This vegetable contains non-heme iron whose absorption can be improved with vitamin C. Low iron levels can cause humans to develop iron anemia. Symptoms of anemia include feeling tired, headaches, weakness, shortness of breath, cold hands, pale skin, or poor ability to exercise.
