"The Beautiful Truth" - another movie about cancer and nutrition

I thank "Chris Beat Cancer" for bringing my attention to this movie. After the 15-year old protagonist, also called Chris, loses his mother, his father decides to home-school him and gives him Max Gerson's book on the Gerson therapy. Chris ultimately embarks on a cross-country tour to speak with scientists, doctors and cancer survivors to find out what's behind the book.

I found the movie informative, but I felt sorry for "the kid", who was likely still traumatized by the loss of his mom, and then had to go on this odyssey to find out that everything in the modern world is bad for you. And I didn't understand the dad's motivation in assigning him Max Gerson's book as a home-schooling project, given that the mom seems to have died in an accident and not of cancer. At one point in the movie "the kid" visits a company that manufactures coffins (the point being that Americans nowadays need larger coffins because they are so fat) and we see him climbing into coffins to test them out for size. This just seemed morbid to me.

At any rate, there is interesting information about things that are very bad for you, such as dental amalgam, aspartame and anything produced by Monsanto (who declined to give an interview) and things that are good for you, such as organic vegetables.
