The answer: It sounds weird, but insects can definitely be good for you because they're a good source of protein and they're low in calories, says Gans. It helps to compare insects to other well-known sources of protein, like chicken and eggs. So here we go: A typical serving size of crickets is 3.5 ounces. That portion contains 13 grams of protein and 121 calories, says Gans. In comparison, that same amount of eggs (about two large eggs) contains the exact same amount of protein and only slightly more calories (154).
