Mat announced the super foods for the Fitness Commitment challenge weeks five and six.
Kale was for week five, and what an awesome choice that was! Kale is one of the most nutrient dense foods out there. It is one of nutritarian Dr. Fuhrman's favorite food choices. You should have kale everyday! Kale lowers your risk of cancer and supports your body's detoxification system. It has Vitamin A, Vitamin C and is very high in Vitamin K, which any Americans often lack. Vitamin K is essential for bone health and brain function.
