Something interesting about a stick of celery:
Quote:Celery is actually loaded with latent energy, but the plant's composition only allows us to metabolize a small amount. The latent energy is packed tightly in the form of cellulose; a complex sugar which humans are unable to metabolize. It's not that the celery is difficult to digest, but rather it provides fewer calories than what is needed to digest it - so the overall effect is "negative calories".
