Believe it or not fruit sugar, fructose, (which is in honey too) is actually more dangerous and and a greater contributor to diabetes than refined table sugar. This is because it is processed in an entirely different way to glucose. If you take too much in one sitting your liver goes into shock and turns it into fat which sits directly around the liver causing all sorts of issues. Now table sugar, sucrose is 50% glucose and 50% fructose but it takes time for the body to split it into the two constituent parts so there isn't a spike in fructose to freak the liver out.

The reason our bodies does this is down to our behavior in the past. Fruit is seasonal so when we eat a lot of it our body thinks "great time to lay down fat for when less food is available". In the modern world fruit is available all year round and your body hasn't adapted to this concept. So it may sound bizarre but careful with that 2nd glass of fruit juice it will do you more damage than even the worst processed crap.
