Hot dogs: tasty barbecue staple, but nitrates demand moderation
Hot dogs provide about 5 g of protein per link but often contain nitrates and nitrites used to preserve color, which can form nitrosamines during cooking or digestion and have been linked to colorectal cancer. Some brands now offer nitrate-free or uncured options (sometimes celery-derived), but these may still form nitrosamines in smaller amounts. Calorie-wise, hot dogs run about 120–150 calories, generally fewer than a plain 4 oz hamburger, though buns and toppings add calories. Overall, an occasional hot dog is fine within a diet focused on whole foods like fruits, vegetables, lean proteins, and whole grains.
