I think you need your head examined. Clearly she was going through a lot of problems, but it wasn't the sand eating that got her were she is at now - she was doing that during her drug problems, etc. If you would have avoided the band wagon and read the captions, you'd know that.
I agree that she appears a little underweight, but she is definitely a lot healthier than her former self. In what I've seen of people, they tend to lose a lot of weight and become underweight, before equilibrating and regaining a more ideal weight when converting to vegetarianism/raw/fruitarian/whatever.
It's also arguable that her emotional problems are/were also CAUSED by these toxins, bad food habits, etc., and if that's the case, then she is definitely on the right track to correcting them by eating pure raw.
I don't understand this negative backlash toward someone who is clearly making a commendable effort in regaining life.
"OMG SHE'S EATING SAND! EMOTIONAL PROBLEMS! QUICKLY, GET HER TO THE DOCTORS SO THEY CAN DRUG HER UP AND MAKE IT ALL BETTER!"
