The beautiful truth (2008) (Uma verdade linda)

A troubled 15-year-old boy attempting to cope with the recent death of his mother sets out to research Dr. Max Gerson's claims of a diet that can cure cancer as his first assignment for home-schooling in this documentary from filmmaker Steve Kroschel (Avalanche, Dying to Have Known). Garrett is a boy who has always been close to nature. He lives on a reserve with a menagerie of orphaned animals, and over the years he's become especially sensitive to the nutritional needs of the diet-sensitive animals he's charged with caring for. When Garrett's mother suffers a tragic and untimely death, the boy falls into a dangerous downward spiral and nearly flunks out of school. Increasingly concerned for Garrett's well-being and determined to strengthen their bond despite the many challenges on the horizon, his father makes the decision to begin home-schooling the distressed teen. Garrett's first assignment: study a controversial book written by Dr. Max Gerson, a physician who claims to have discovered a diet that's capable of curing cancer. Is Dr. Gerson's therapy truly the legitimate, alternative cure it appears to be? In order to find out the truth behind this long-suppressed treatment, Garrett interviews not only Dr. Gerson's family members, but various doctors, skeptics, and cancer patients as well. His studies completed and his findings revelatory, Garrett now sets out to tell the entire world about The Gerson Miracle.
