Danielle Cook faced every mother's nightmare when her 11-year-old son was diagnosed with stage three Hodgkin's lymphoma. After the initial shock, she turned to nutritious meals, and the change seemed like a true miracle.

She said that at first, everything seemed dark:

"There was a huge sense of powerlessness and great sadness."

Yet, this mom of three worked for years doing cooking demonstrations in the Washington, D.C., area. So she made it her mission to help her ill son, and after months of unique recipes, she saw her boy go from a "worn, depressed, tired kid to a healthy adolescent."

Sound simple, yet even Hippocrates, the father of modern medicine, believed that there's power in healing with food.

Danielle Cook is now a holistic nutritionist and a published author. Her son inspired her to found Happily Hungry. It's a program that consists of cooking and workshops for hospitalized kids and their family members who are battling cancer and other illnesses.

This mom's job also includes educating people on what they can do to help their ill children. Her book "Happily Hungry: Smart Recipes For Kids With Cancer" will surely help all parents boost their children's immune system and make them stronger to fight for their lives through kid-friendly recipes.

Reportedly, Cook's book is a "roadmap for healthy eating choices during cancer."
