A little help would be beneficial in this aspect.
a)Dextrose- This is highly regarded as an ideal PWO source of carbs, but it comes from corn, and I wonder, why such source is good. Isn't corn a bad carb source? I've read that many people are intolerant to corn, can develop allergies because of it, and can even slow down your metabolism....
b)Maltodextrin- Corn sugar again....
c)Waxy Maize Starch- Is it better than Dextrose or Maltodextrin? Or is it all hype?
d)High Fructose Corn Syrup- I've read only negative things about this stuff, but would like to know what's the difference between this and Dextrose/Maltodextrin, since all of them come from corn.
e)Fructose- Would it be ok to drink something like 100% Grape Juice for PWO? If not, why?
I know there are a couple of questions here, but any help will be greatly appreciated, since I'm pretty confused in this topic.
