Some of the ingredients in Pepsi are carbonated water, high fructose corn syrup and caramel color. It also contains sugar, phosphoric acid and citric acid, notes PepsiCo Inc. There is no fat or protein in Pepsi, and it has 41 grams of sugar. Pepsi contains 14 percent of the necessary daily carbohydrates, based on a 2,000 calorie diet. Pepsi also contains ten milligrams of potassium and 53 milligrams of phosphorous.
Phosphorous is a mineral that is a necessary component of the human diet. Pepsi contains phosphoric acid to create tartness that leads to a small amount of phosphorous in the drink. Phosphorous is important for bone health, and Pepsi only contains four percent of the necessary daily amount of phosphorous so it is not enough. Other Pepsi products such as Pepsi True and Pepsi-Cola made with real sugar contain more phosphorous, with 60 milligrams or more in each can. Other foods contain more of the daily recommendation of phosphorous such as peanuts with 107 milligrams and an 8 ounce cup of milk with 247 milligrams of phosphorous.Learn more about Calories in Food
