I must confess that I may have been unduly influenced by reading a book
by Nicholas Perricone, /The Perricone Prescription/, and by watching his
shows on television. After reading the page about him at
http://www.quackwatch.org
, I'm less persuaded.
On the other hand, according to /Metabolism at a Glance/, 3ed by J. G.
Salway, "fructose is metabolized rapidly in humans, having a half-life
of 18 minutes. In fact, it disappears from the circulation twice as
rapidly as glucose." It "is able to enter muscle cells and adipocytes
in the absence of insulin...." (So it avoids the rate-limiting step
controlling glucose absorption.)
Furthermore, the pectin in fruits (according to /Understanding
Nutrition/, 8ed, p 97) prolongs GI transit time, "delays glucose
absorption," (and, I suspect, that of fructose as well), and "lowers
blood cholesterol." But when drinking fruit juices, as opposed to
eating whole fruits, you're avoiding these protective benefits.
I was warned against drinking orange juice alone (as you've been doing)
when I was diagnosed with hypoglycemia, but that advice may not be
applicable to everybody.
However, that sort of eating (substituting a glass of orange juice for a
balanced meal) certainly isn't in line with the standard dietary advice
advanced by the government, the United Nations, or any reputable sources
of nutritional information that I'm aware of.
So I'm not sure whether it raises glucose, insulin, or cortisol levels
(as soft drinks do, and as I read that orange juice did, too), but I am
convinced it may give you a quick rush of energy, it's not a good habit,
and the most reliable authorities advise against it.
