Avoid smoothies. When the fiber is pureed, it is not chewed and does not have the opportunity to mix with the facultative anaerobic bacteria which reside in the crypts and grooves or our tongue. These bacteria are capable of reducing the nitrates in green leafy vegetables to nitrites in the mouth. When the nitrites are swallowed, they are further reduced by gastric acid to nitric oxide which may now enter the nitric oxide pool. Furthermore, when chewing fruit the fructose is bound to fiber and absorption is safe and slow. On the other hand, when fruit is blenderized, the fructose is separated from the fiber and the absorption is very rapid through the stomach. This rapid absorption tends to injure the liver, glycates protein and injures the endothelial cells.
