Apologies, I should have said Soylent 1.5. Not sure why you decided to say "both false", however, given that sucrose most certainly has a GI of 65. Further, what is the relevance of saying _powder_. You realize that mixing a powder into water generally doesn't reduce its GI, right?
Further, saying "white bread is worse" is a laughable diversion. White bread is considered the unholy worst case for GI, so being better than it is not a high mark.
I beg to differ. White bread and other baked goods like bagels, pizza, etc are a staple of the western diet, so it is absolutely a valid baseline for comparison. People don't regularly consume plain table sugar.
Moreover, as far as I know, Soylent 1.5 powder isn't even being sold anymore. According to the Soylent site, the current version being sold is 1.8.
Therefore, I think I'm perfectly justified in calling your statements misleading.
Both false and misleading. According to the link provided by the parent poster:
-Soylent 1.6 _powder_ has a GI of 60
-Soylent 2.0 _liquid_ has a GI of 49.
Also, note that common white bread has a glycemic index of 75, which is higher than that of table sugar (65), so your statement, even if you had used the right number, is not as much of an indictment as you make it out to be.
