Isn't dextrose just glucose? That doesn't seem healthy at all. In moderation to give you a boost, it would probably be fine, but you definitely shouldn't get a significant amount of calories from straight sugar. As a vegetarian who has to worry about protein, I think about that a lot. Basically, the more crap you eat with no nutritional value, the more nutrient-dense the rest of your food has to be. So if I got all my calories from rice, I'd be fine protein-wise. But if I eat 500+ calories of various things-that-are-just-fat-and-sugar, I need to eat more protein-dense food, like lentils. (Not that just eating rice would be healthy anyway. That's just an example of how the more nutritionally-useless calories you get, the healthier the rest of your food needs to be.)
