15 Amazing Health Benefits of Fennel

Fennel Benefits

1. Helps Lower Cholesterol Levels

Foods high in fiber are capable or helping to reduce blood cholesterol levels, and luckily fennel is no exception. Fiber in fennel helps to prevent the full absorption of cholesterol into blood, subsequently preventing its deposition on artery walls. Fiber also has a way of promoting bile excretion, which then mandates replacement of this enzyme via conversion from cholesterol. Both of these mechanism are excellent for reducing circulating cholesterol levels in the blood.

2. Can Support Bone Health

While fennel does not have a high amount of calcium, every little bit helps when you are a vegetarian and have a hard time finding non-dairy sources of calcium.

Adequate vitamin C consumption also helps prevent wrinkles and age spots.
