most of this stuff is over my head cause i find the "scientific expert" type stuff boring but heres a few ppl who are jumping off the pure dextrose bandwagon.
this is from a post by alan aragon
---- 60-120g of high-GI carbs (0.5g/lb target BW), or a combination of types that ultimately averages to a high-GI rating (70 or above). dextrose & maltodextrin have traditionally been emphasized as ideal for postworkout because of their high-GI. however, i have issues with going pure dex for postworkout for a couple of reasons - and they have nothing to do with the threat of insulin resistance, because that whole scenario applies to a completely different population. first off, you can get some default dex within fruit or milk. secondly, pure dex has no micronutrient density, and i've said it before, antioxidant micronutrition is grossly under-emphasized whenever postworkout nutrition is discussed. dex is a fine addition to your postworkout carb arsenal, but to go pure dex for the largest carb hit of your day doesn't make sense from a micronutrient density standpoint - especially when dex is contained in other foods that are more nutrient dense and are still either high-GI or highly insulinemic.

There has been some controversy about which type of carbohydrate is best for post exercise glycogen replenishment. Some argue that simple sugars such as dextrose are best after exercise. Others say that drinks with glucose polymers are best. Still others say that there is no need to buy fancy sports drinks and that simply eating a meal high in carbohydrates such as pasta or rice is sufficient. Studies have shown no difference between different types of carbohydrates eaten post exercise and the rate of glycogen replenishment as long as sufficient quantities of carbohydrate are consumed (Burke 1997). Even when the post exercise meal contains other macronutrients such as proteins and fats, the rate of glycogen replenishment is not hindered, given there is sufficient carbohydrate in the meal as well. These studies tell us that the rate-limiting step in glycogen replenishment after exercise is not in digestion or the glycemic index of a given source of carbohydrate. Over a 24 hour period it is the total amount of carbohydrate consumed that is important.

Even in considering post-workout nutrition, there is still little proof that a liquid protein-carb complex will actually produce better muscular growth than whole foods, as long as complete whole food protein foods and complex carbohydrates are consumed immediately after the training session and every three waking hours for a period of 24 hours thereafter.
