Thanks Jane for the great question.
In fact when you eat fruit whole, eating the fiber slows down the absorption of the sugar. Drinking fruit juice (even freshly squeezed or juiced in a juicer) does cause a fast absorption of the sugar and many times I have read advice against drinking too much juice for this reason. A smoothie is different because in a smoothie you keep the fiber in the drink, it is not extracted the way it is in a juicer. For smoothies, I suggest a K-Tech blender for its strong/dependable motor and fitting under kitchen cabninets.
A couple studies I found will say juice still finds its place at the table, helping prevent cancer: “Double strength orange juice given to the rats in place of drinking water inhibited mammary tumorigenesis induced in female Sprague-Dawley rats by DMBA more effectively than double strength grapefruit juice.” (Inhibition of mammary cancer by citrus flavonoids. Adv Exp Med Biol. 1998;439:227-36)
“The results with naringin and naringenin show that both of these flavonoids significantly lowered tumor number [5.00 (control group), 2.53 (naringin group), and 3.25 (naringenin group)]. Naringin also significantly reduced tumor burden [269 mm(3)(control group) and 77.1 mm(3)(naringin group)]. The data suggest that naringin and naringenin, 2 flavonoids found in high concentrations in grapefruit, may be able to inhibit the development of cancer.” (Inhibition of oral carcinogenesis by citrus flavonoids. Miller EG, Peacock JJ, Bourland TC, Taylor SE, Wright JM, Patil BS, Miller EG. Nutr Cancer. 2008;60(1):69-74).
Overall, eating more fruit fills your body’s craving for sweetness and can reduce your interest in gaining it in other ways (i.e. processed sugar which is dumped into many packaged foods-it is an effective marketing strategy to get users hooked). Fruit keeps you regular (how do I say that nicely?, it is important to know, if you are having trouble there try increasing your daily fruit intake).
Developing a hankering for fruit can turn into a craving for bitter flavors in fruit like the white of a grapefruit. This can open you up to a whole new realm of tastebud extravaganza. This happened to me and now I have cravings for nibbling on a head of raddichio.
On the go, fruit is the ultimate packable “water bottle”.
