Shawn,
	Most of the fruit commercially on the market nowadays has been
hybridized, cross-bred, and/or genetically engineered to have a higher
sugar content than the original varieties it came from.  This can be
measured scientifically, no guesswork required.  Fruit trees are often
(usually?, always?) planted from graftings of hybrid plants, not from
seeds.  Pineapples are totally artificial fruits.  There is no such thing
as a pineapple seed; they are all grown from graftings of existing plants
that were created as hybrids from original ancestors that were not so
sweet.  Companies involved in agricultural research do this.
	Consider: Total refined sugar consumption of the average American
has about tripled during the 20th century.  Today's fruits have to
compete in the marketplace with candy bars, ice cream, cake, and all the
other sweet garbage foods that people eat.  Industry has responded by
growing sweeter-tasting varieties of fruit for fear consumers with their
jaded sweet teeth wouldn't buy them otherwise.  Get it?
	I wish it weren't so, Shawn, but the commercial interests,
whether by conspiracy or just by their own desire to make a buck, are
making it harding and harder for us poor souls who are just trying to
lead a natural lifestyle to succeed at what we are trying to do.  With
the Brave New World of genetic engineering just opening up in a big way
(where they can splice fish genes into tomatoes, or create genes to
produce pesticides and splice those into other foods), it may not be too
long before a truly natural diet becomes impossible for anyone.  Again:
it could be conspiracy, or it could just be that the apathy and ignorance
of the consumer will allow it to happen by default.
