Coke Zero is a calorie-free and sugar-free soda made by the Coca-Cola company. It is an alternative to Diet Coke, the traditional diet calorie-free version of Coke. "Zero" is a reference to the caloric content of the soda. Coke Zero is widely available and can be found in most grocery stores and most Coke vending machines. If you frequently drink Coke Zero, you should be aware of the risks and benefits of this soda.
Coke Zero contains caffeine, which can increase your alertness. According to the Center for Science in the Public Interest, a 12 oz. can of Coke Zero contains 35mg of caffeine. A 20 oz. bottle of Coke Zero contains 58mg of caffeine. According to a 2008 study by the Sensory Neuroscience Laboratory in Melbourne Australia, caffeine significantly increased alertness and enhanced performance in well-rested individuals.
Another benefit of Coke Zero is that it contains no calories and is sugar-free. Most regular sodas are made with high fructose corn syrup. According to the American Journal of Clinical Nutrition, high fructose corn syrup may play a role in the obesity epidemic in the United States. Researchers believe over-consumption of beverages that contain high fructose corn syrup has significantly contributed to obesity. Coke Zero is sweetened with sucralose, commonly known as Splenda, which is a calorie-free sweetener. Coke Zero can serve as a sugar-free replacement for regular sodas that contain high fructose corn syrup.
Coke Zero can cause insomnia if consumed too close to bedtime. According to Geneseo State University in New York, you should not consume caffeine within four hours of going to bed. For most people, caffeine contributes to insomnia. The University of Kentucky says that people who have insomnia are more sensitive to the effects of caffeine than people who do not have insomnia. For insomniacs, the University of Kentucky suggests removing caffeine from your diet altogether. Even if you do not have insomnia, if you have high blood pressure or are sensitive to stimulants, avoid Coke Zero. Consult your physician if you are having trouble falling asleep on a daily basis.
