Diet Pepsi
A popular zero-calorie sugar-free carbonated soft drink.
What is a Diet Pepsi?
Diet Pepsi is a carbonated soft drink that is marketed as a low-calorie alternative to regular Pepsi. It was introduced by PepsiCo in 1964 and has remained one of the leading diet sodas globally. The drink uses artificial sweeteners like aspartame to replace sugar, giving it a sweet taste without the added calories.
Diet Pepsi is fizzy and has the signature cola flavor, which combines sweetness, tanginess, and slight bitterness. It is available in multiple variations, including caffeine-free and flavored versions like cherry or lime.
Nutritionally, Diet Pepsi is known for being calorie-free and having no sugar, fat, protein, or carbs. However, it contains artificial sweeteners, sodium, and trace amounts of other additives that contribute to its flavor and preservation.
