It depends on what you're using the crickets/insects for. When we humans eat corn-fed meat sources, you aren't exactly getting a burst of nutrition for the same reasons you point out. You're still getting the fat and protein from the meat. I'm guessing the same is true for commercially-raised crickets. The point is that the crickets are not the only thing being consumed, they are being used for their protein and fats while other parts of the diet/meal add necessary nutrients.
