"once read that juicing is benefical because it takes 5 of todays apples to equal in terms of nutrition 1 apple 50 years ago"
WOW!....
Somehow I believe that.
I saw a program hosted by Alan Alda this last year I think it was
where he was talking with one of the people from some experiment
back in the 70's. Biosphere or something? Anyway, the guy was
a living example according to himself if I remember right, that
longevity and small food intake are connected. I wonder if nutrient
packed calorie intake like juicing greens would count?
Anyway, I cannot confirm nor deny the claims from the program
but I believe that the name was Scientific American Frontiers.
