The sugar in grapes....

Quote  |  Reply

Are they good sugar or are they the same sugar i would find in like soda?

the sugar you find in soda is added, but the sugar you find in grapes or any other kinds of fruit or vegetables are natural. there is a BIG difference between the two; natural sugars = good, refined/added sugars = bad.

fruits and veggies have sugar in them, but they are good sugars.

Few fruits contain 20 percent sugar when ripe, so grapes are unique in their high sugar content. Most grapes contain about equal amounts of glucose and fructose. However, Chardonnay contains more fructose than glucose. Zinfandel contains more glucose. Grapes also contain small quantities of sucrose and several other sugars.

fyi sucrose is glucose + fructose (the molecules bond together = sucrose), which is the same as 'table sugar' (and what is in some sodas)...but like it says, only small quantities. I wouldn't worry too much about the sugars in fruits, they're 'good' sugars and you DO need sugar anyways.

Vicereine's information is interesting, because it was my understanding that grape sugar is primarily glucose.  Glucose is bad if you have any problems with regulating blood sugar.   It is also not as sweet as fructose, so you have to use more to get the same sweet taste.  But glucose also has a reputation as something of an appetite supressant - meaning that a few grapes or raisins should do more to kill off appetite than eating a cookie as a snack.  It doesn't work for me raisin leads to many more, and a little box of them packs a soda's worth of calories.   Except for the fiber content, I consider them to be a naturally-occuring junk food.

Made into dry red wine it's a different story though.

Well, sugar is sugar. But using common sense, it's obvious that fruit can't even be placed in the same category as soda.

My understanding is that the length of the sugar molecule affects how your body burns it for energy.  The shorter the molecule (e.g. glucose or fructose molecules) the faster your body will burn it up.  Your body will turn to longer molecules (like high fructose corn syrup...::shudders:: ) after the shorter ones are all used up.  I think it works that way because your body goes for the easiest energy source first.

qpx and mimi_is, sugar is sugar.  It's all the same molecular weight (or very close), unless it's polymerized into a polysaccharide such as cellulose or starch.  It all comes from plants, so even high fructose corn syrup has a natural origin (it's made from corn starch, as is regular corn syrup).

The sugar that comes directly out of a grape would be completely unrefined, and would bring along anything else in the grape (seeds, skin, stem, water and a few non-sugar chemicals).  So in that sense it's different from a soda, which contains a mix of flavoring, carbon dioxide and refined sugar of some kind.  I still don't see them as being that much different in what they do, though.  The sugar is the same whether you get it from a grape or from a soda. It's not good sugar or bad sugar - it's all-the-same sugar.  In my case they're all bad.  I got type 2 diabetes by eating too much raisin bran, not from drinking soda.  I could have done it with soda just as easily, but I did the all-natural way. 

Haha! I agree about the wine part!

Not all sugars are the same.  See "Sugar:  The Bitter Truth" on youtube.   Fructose won't raise your blood sugar as much but can lead to the same health problems as ethanol.  Table sugar, sucrose, is half fructose, as is high-fructose corn syrrup.  Glocose is better for your health and satisfying appetite. 

I would like to know the ratio of fructose to glucose in grapes.  Was hoping to snack on raisins.
