Monkfruit sweetener is amazing because it is so close to normal sugar. You really have to pay attention to notice the difference. I did read that there is a downside to even things like Monkfruit sweeteners, and it has to do with signalling. So, while we are not getting the negative effects of too much sugar, we are still signalling to our brain that we are consuming sweets and that turns on and off various subsystems in our bodies that still potentiall cause issues. One thought on this is that we evolved to consume as much sugar as possible because it was only ever available for a couple of weeks at the end of the summer. This sounds normal until you realize that this was a signal to the brain that the END OF SUMMER is here and that winter is coming where there is no food. So, through evolutionary selection, sugars never ended up triggering satiation signals in our bodies allowing us to consume as much as possible in order to fatten up for the long winter of nothing. If you read up on sugar, sugar has no satiation point. You can only eat so much fat, meat, protein and green veg because they trigger satiation points and your body stops you from consuming. Sugar? It has none. Sugar keeps you eating. Anyway, the problem with Monkfruit is that it has none of the chemical effects BUT it is still signalling sweet to our brains which is thought to trigger all kinds of things including the primary signal that starvation is around the corner. This is all speculation though, just stuff I read.
