Fructose vs Sucrose

Fructose is not the same as sucrose -- and they have different properties. The same is true about how its consumed, and how fast it's absorbed.(In fact fructose -- present in fruits -- can even be worse than table sugar: http://www.healthline.com/health-news/evidence-shows-some-su...).That said, I seriously doubt the probl

High fructose corn syrup is not the same thing as fructose, all other things being equal. Fiber also helps modulate the insulin response. Sugar isn't the enemy, if you're eating fruit you're getting a lot more than fructose from it. The problem is when people get a large % of their calories from nutritionally deficient food, like soda.

I'm not a biologist, related from Lustig's video, probably incorrectly:fructose + glucose = sucrose. Body needs glucose. Fructose goes straight to liver, metabolized like alcohol, a bunch of bad stuff happens. Reason fruits are better than fruit juice is the fiber blocks the fructose from being metabolized, letting the needed glucose through.Eating straight refined sugar is probably almost as bad as HFCS. But other sources of sugar (in moderation) are proably fine.FWIW, I add

Sugar is 50% fructose and 50% glucose. The user you mention advocates for a higher amount of fruit which has mostly fructose so my take on this is that he prefers his pancreas over his liver.

Actually both are true, glucose and fructose have way different biochemical impact on the both. For starters, only 20% of glucose is metabolized by the liver, rest goes to muscles, brain etc. While fructose completely goes to the liver, since muscles and brain cannot make use of fructose directly. Another effect fructose has is that it sort of suppresses ghrelin (https://en.wikipedia.org/wiki/G

Fruit juice? Does fructose vs sucrose make a difference?

Fructose, which is in high abundance in fruits, is the sugar to avoid. Sucrose = Fructose + Glucose. So saying "don't worry about the sugar, this is not sucrose" is misleading. Glucose is the sugar that your body is designed to digest/process. The reason that fruits are better for you than sugary things is because the amount of fructose is smaller than in most other things, and most fruits contain a lot of fiber.

I'm wondering why you're flagged. Yes, fruits have sugar (fructose), but when you're eating the fruit whole your comment is on point. The fiber in the fruit makes the sugar absorption slower.Of course if you're drinking 2L of juice a day you're gonna have a problem, as you would going ham on any kind of food. (ANY)

I mean bad sugar, one glucose molecule (not so sweet) plus one fructose molecule (very sweet), like HFCS https://en.wikipedia.org/wiki/High-fructose_corn_syrupFruits and vegetables have fiber, its a different story.By the way he goes on talking about diet soft drinks, and explain that they are also bad, you produce insulin anyway.

Yes, that fructose.You are correct. HFCS is unassociated glucose and fructose, and to my understanding is pretty much interchangeable with sucrose, as sucrose is enzymatically cloven almost immediately.I will throw in that firstly, it is theorized that the fiber in apples etc provides some regulation to the absorption of the fructose and that somehow changes matters. Secondly, and in my mind more importantly, it is much easier to gorge on pure sugar than it is to eat an equivalent amount o
