Right. A disaccharide like sucrose (table sugar) is easily cleaved into a fructose and a glucose… and that fructose and glucose are chemically identical to any other fructose and glucose, and will be have all the same effects as any other fructose or glucose.
(Some disaccharides are less easily cleaved, and so it takes a long time before they base sugars are free… but those disaccharides aren’t relevant to this discussion.)
Yes - if you want to read the whole study he referenced, click here.
The fiber in whole berries slows down the sugar absorption, but also, the berries contain proanthocyanins and anthocyanins which inhibit the sugar uptake. The ugly side of this is to consider the role of proanthocyanins: it’s a plant defense which is toxic to insects. It also happens to screw with our digestion and inhibit our ability to take up sugar. Fortunately, it’s not nearly as bad for us as it is for insects, and slower sugar uptake is a good thing for modern diets.
However, he does get one important detail wrong… he talks about the body spiking the blood with fats in response to the hypoglycemic “starvation” effect after drinking the sugar-water… that’s pretty bogus. What’s really happening is that after you consume berries or sugar-water, the body stops putting fats into the bloodstream (because when sugar shows up in the blood, the fat is not necessary, so it stops - sugar is your body’s preferred fuel.) When the sugar runs out, the body starts putting fat back in the blood. Since the sugar runs out quickest after a sugar-water meal, the fat returns sooner - but it’s not some sort of fat-spike panic response, as he suggests. It’s just the body trying to return the fat levels to normal. In other words, returning the fat levels to where they were before you drank the sugar.
Here’s the relevant picture from the study, which he didn’t show:
So, as you see, the sugar drink (called “Reference”) does have a bump up in fat between the 60 and 120 minute (2 hour) marks, but it’s not some sort of crazy spike. It’s just working its way back up to normal after the sugar is used up at 60 minutes. And normal, by the way, is where it started at minute 0, when they started drinking. As soon as the sugars start hitting the blood, the fat starts dropping… and it doesn’t start to rise back to normal until all the sugar is gone.
For easy reference, here’s the corresponding blood sugar chart:
The fat would also rise in the next hour for the berry trials, because the fat is going to rise back to normal in all three cases. It just doesn’t start until the sugar is all used up - which, for the berries, doesn’t happen until about 120 minutes.
No, I don’t think Soylent wants to be caught putting a toxin that inhibits digestion into Soylent to slow down sugar uptake. People would point and scream.
