While Coke Zero has zero calories and no sugar, it offers no nutritional benefits and contains artificial sweeteners and phosphoric acid that can be problematic with regular consumption. The main concern is aspartame, which despite FDA approval, has been linked to potential metabolic disruption and increased cravings for sweet foods in some studies. The drink contains 40mg sodium and 60mg potassium per can - negligible amounts that don't meaningfully contribute to daily mineral needs. The phosphoric acid content may interfere with calcium absorption if consumed regularly, particularly concerning for growing children and those at risk for osteoporosis. The artificial sweeteners (aspartame, acesulfame-K) can maintain sugar cravings and may affect gut microbiome. Some people report digestive issues with these sweeteners, though responses vary individually. If you're looking to quit regular soda, this can be a stepping stone, but don't make it a daily habit. Better alternatives for a refreshing drink: sparkling water with a splash of juice, unsweetened tea, or water infused with fruit/herbs. If you do drink it, limit to occasional consumption and don't serve with calcium-rich meals due to the phosphoric acid.
