Yes fennel is considered to be a superfood and contains fiber, potassium, folate, vitamin C, vitamin B-6, and phytonutrient content.
Those are all things we need to stay healthy so eating fennel can improve your health and it's good to eat in salads as well.
I love adding fennel to my salads and when I do add fennel to my salads I find that I have a boost in energy as well so that's another benefit of eating fennel.
Just like bananas have energy boosting potassium fennel also contains the same amount of energy boosting potassium which improves your energy levels and health.
