I'm currently experimenting with making a DIY soylent and I've noticed that if you're trying to get all the carbs from whole-grain, real sources you end up getting a lot of fiber (~50g/day even when doing a relatively low amount of carbs like 35% of your daily calories). A lot of people report feeling bloated and painful from too much fiber. It also adds up in price. So, they supplement with fast-burning carbs like maltodextrin and sugars (soylent is trying out the slower burning sugar isomaltulose).
I'm a little skeptical that something that gets broken down into half fructose and half sucrose exactly like table sugar and HFC is harmless if it just gets digested slowly, that'd be like saying drinking soda is totally healthy as long as you sip on it slowly all day instead of getting too much at once.

Which suggests as the guideline and inclues a 20g limit (which the squares are still over):

Yes, there is disagreement but no I'm not going to take "disagreement" as "HEY LETS GO OVER THE DAILY LIMIT!!!"
To me the problem is the sugar content. It's easily double, even for a large man, and almost triple for a small woman.
