How much Diet Coke should seniors drink per day?
It’s generally safe to drink one or two cans a day. Drinking a reasonable amount of diet coke a day, such as a can or two, isn’t likely to hurt you. Current diet coke ingredients, including artificial sweeteners and other chemicals, usually are safe for most people, and there’s no credible evidence that they cause cancer.
Many diet sodas even come enriched with vitamins and minerals. But you should bear in mind that diet soda is not a weight loss or a health drink. Even though it may lower calories compared to regular soda, there is still no clear evidence showing it will effectively prevent obesity and related problems in the long run.
