soaps on telly and people talking about the characters as if they were real.
I read Dr. Mercola regularly. I think he's sometimes very OTT, but occasionally I fing a gem in his column.
I've read before that cholesterol is essential and believed the evidence, just as I don't believe there's much for the PC point of view, but i like this from the latest Mercola. Suggestin the REAL dangers to heart health.I
I thought this interesting as so many of us are regularly above this level and Heart disease is common in Diabetes,

"Your fasting insulin level: Any meal or snack high in carbohydrates like fructose and refined grains generates a rapid rise in blood glucose and then insulin to compensate for the rise in blood sugar. The insulin released from eating too many carbs promotes fat and makes it more difficult for your body to shed excess weight, and excess fat, particularly around your belly, is one of the major contributors to heart disease "

PS I know Fructose doesn't raise BG. I'm sure Mercola does really!
 
According to a study by Shambaugh et al, 'Differential effects of honey, sucrose, and fructose on blood sugar levels', fructose has least effect, then honey and then sucrose has the greatest effect. You can get fructose, glucose and sucrose in fruits, sucrose being bonded glucose and fructose. You don't get sucrose in honey, just fructose and glucose. I can't think of any natural foods which contain fructose only but at one time it was thought that it was a good sugar substitute but these were in concentrations far higher than found in natural foodstuffs.

About 240,000 tons of fructose are produced in crystaline form commercially and used as a sweetener, it's nearly twice as sweet as sucrose. It is absorbed directly via the intestine. Sucrose on the other hand, which is bonded fructose and glucose, needs to broken down by enzyme action first. It's the artifically high concentrations of fructose in some products which make it potentially dangerous for type 2 diabetics.

There's quite an interesting table on the wiki page for fructose which gives the relative types of sugar found in various fruits and vegetables: http://en.wikipedia.org/wiki/Fructose

Looking at that table, you'd probably not be advised to eat lots of dried figs, even though they have low levels of sucrose.
