Doritos has introduced Doritos Protein in the US, adding a higher-protein option to its range. A 30-gram serving contains 10 grams of protein, compared with around 2 grams in classic Doritos Nacho Cheese. That is roughly five times the protein in the same portion.

Chickpea and lentil chips already offer alternatives in the snack aisle. PepsiCo links its new product to consumers looking beyond flavour and paying more attention to the protein content of their snacks.

Doritos Protein is an example of this interest reaching established chip brands. Rather than simply adding another flavour, the brand is offering a familiar snack with a different nutritional profile, highlighting protein alongside taste as another reason to choose it.
