Coke is not healthier than Pepsi because both sodas contain very similar ingredients. The major difference between the two is the amount of sweetness. From a health perspective, both beverages are full of calories and sugar, making regular consumption a cause of health issues and weight gain.
Drinking Coke or Pepsi should be done in moderation because overindulging can lead to tooth decay and restriction of Vitamin K in the body. Even diet Coke or diet Pepsi may lead to health problems because of the artificial sweetener. The sweetener has the potential to trick the mind into craving even more sweets soon after.
