Pepperoni is a processed meat high in saturated fat (17.69 g per 100 g) and sodium (1,580 mg per 100 g — about 69% of the daily limit). It provides moderate protein (19.25 g) but at a very high caloric cost (504 kcal). It contains cholesterol (97 mg per 100 g). In small amounts as a flavor addition it is fine, but it should not be a primary protein source.

Pepperoni has 1,580 mg of sodium per 100 g — about 69% of the daily recommended limit in a single 100 g serving. Even a small serving (28 g, ~15 slices) contains 442 mg of sodium. When added to pizza (which already has sodium from cheese and sauce), the total sodium can exceed daily recommendations quickly.

Yes, pepperoni is excellent for keto with only 1.18 g of carbs per 100 g and very high fat (46.28 g). The fat-to-carb ratio is nearly ideal for ketogenic diets. A serving (28 g) has just 0.3 g of carbs. Watch the calorie density (504 kcal per 100 g) and check labels for added sugars in some brands.

Pepperoni is an American invention inspired by Italian salami. It is spicier (uses paprika and chili), finer-ground, and typically made from both beef and pork. Traditional salami varies widely but is generally milder in flavor. Nutritionally, pepperoni (504 kcal, 46.28 g fat) and hard salami (378 kcal, 30.6 g fat) differ significantly — pepperoni is more calorie-dense and fattier.
