Got Juice?

no, i'm not talking about steroids, for once. i'm actually talking about fruit juice.. or to be more specific, fructose (fruit sugar). I've always had the impression that sugar is sugar. it turns out that there's a lot that we don't (or didn't, after reading this) know about sugars. let's talk about the major types of sugar that we see and eat in our daily lives:
sucrose,which is a combination of fructose and glucose
lactose, which is milk sugar
fructose, which is fruit sugar
and glucose (dextrose), which is blood sugar
of course, there are other types of more complex sugars, but you won't find them often in your daily meals. anyways, I used to always drink 500-1000 ml of fruit juice after my workouts to compensate for all the depleted glycogen stores in the muscle cells. but 8 months ago i switched to glucose instead of fruit juice. why? BECAUSE FRUCTOSE IS EVIL!!! IT'S THE DEVIL!!! no, seriously, i'll explain everything.
you see, all sugars weren't created equally. fructose has a phenomenal property of loading glycogen ONLY IN THE LIVER!!! it will never reach muscle cells. meaning, if you don't burn it, it will eventually turn into fat. on the other hand, glucose and other complex carbohydrates (maltodextrin, oats, yams, brown rice...etc.) load muscle glycogen first, then liver glycogen. So, fructose is only good as a PRE-WORKOUT meal. you have to be at the gym within 2-3 hours of ingestion in order to let all that liver glycogen fuel your workout. otherwise, it has no use in bodybuilding. that's why i've advised almost everyone who asked for a diet in the past six months to use glucose as their post workout carbohydrate (if they have carbs in their post workout meal).
what's my main point? i'll tell you........ F*** FRUITS!!! i get my vitamins from pills, and fibers from oats. i have no need for those bitches except for a preworkout meal or if i'm really craving sugars. anti-oxidants my ass... get some pills and pop'em.. 10 times better than fruits.

    I have a quick question that is vividly related to this subject. What type of sugar in dominant in honey?
    I understand that there are different grades of honey out there, but I would like to hear an estimation, if possible.

    Thanks

  2. honey is a 43/57 mix of glucose and fructose. It stuck in the back of my mind a while back that it was 40/60 ratio of glc/frc. but a simple yahoo search gave me the exact ratio, and it only took 10 seconds. not to be offensive or anything, but a simple search could save you lots of time and help you uncover lots of different info that you didn't know, instead of just asking and waiting for days for a reply.

  3. btw, different kinds of honey have almost the same ratio of sugars, the only difference is the amount of antioxidants in the honey. dark, fresh, waxy honey (the really expensive kind) has over 20 times more antioxidants than regular light honey in grocery stores. still, an antioxidant pill has a lot more than that. so i don't want to hear stories about how your grandfather lived to be 200 years old because he downed a jar of honey every day.
