On average, one portion of a corn dog contains approximately 330 calories, 10 grams of protein, and 35 grams of carbs. If you consume corn dogs occasionally and stick to healthy portions, they should not affect your overall health or interfere with your rational weight management. If you want to make your corn dogs healthier, try air frying them instead of deep-frying in oil. Also, using quality sausages from real meat instead of heavily processed products can make this comfort food much healthier.
