...No, not Peanut Butter. Paul Bragg! He once had a conversation with a 15 year old Jack Lalanne:
PB: Jack, what do you eat for breakfast, lunch and dinner?
JL: Ohhh, uh, cakes, pies, and ice cream.
PB: Jack, you're a walking garbage can!
From then on, Jack Lalanne began his journey of going mostly raw and then HE became one of the super stars of nutrition and great health; passed away at age 96. He did a 2 hour workout the day before he passed. (I believe he'd made it further, but he passed of pneumonia and refused to go to the doctor because didn't want to take drugs. He might have lived longer had he taken some antibiotics...but then I admire him for refusing to get on drugs)
