As an RD, I am always skeptic and disturbed by
the abundance of health bars that are out there, claiming to be «healthy» but in fact, are not that nutritious at all.
Apples and celery are great for your
health, and I do recommend you eat them (and all fruits»n veggies) in
abundance, but they're not very satisfying replacements for a
bar of chocolate, bag
of potato chips, ice cream, or a slice
of cake.
