2. Cholesterol reduction: Like many whole foods, broccoli is packed with soluble fiber that draws cholesterol out of your body.
3. Reducing allergic reaction and inflammation: Research has shown the ability of kaempferol to lessen the impact of allergy-related substances on our body. Broccoli even has significant amounts of omega 3 fatty acids, which are well know as an anti-inflammatory.
5. Bone health: Broccoli contains high levels of both calcium and vitamin K, both of which are important for bone health and prevention of osteoporosis.
