Spoonful of any kind of sugar makes the protein go down after exercise

It's clear that carbohydrates with protein affects insulin, thereby inducing glycogen synthesis. However, I was left thinking, “But what kind of carbohydrate is best?” And I found a study that suited my curiosity. One published in 2007 in J Int Soc Sports Nutr showed that 40 subjects who weight trained taking 40g of whey protein were also given 120g of sucrose, honey or maltodextrin (1). After 30 minutes, the honey group showed greatest glucose concentration and best degree of blood glucose maintenance; however, there was really no significant difference and either can be used (1).
