If there’s one word defining food trends in 2026, industry analysts agree it’s protein — and not just in the categories you’d expect.
It’s showing up everywhere now. Nestlé has rolled out high-protein frozen ready meals and developed a proprietary whey microgel to boost protein content in milk drinks without changing the taste. Danone is launching protein shots delivering 10g of protein per serving for muscle health. Even coffee chains are in on it — Starbucks now offers Protein Lattes and Cold Foam drinks delivering up to 36g of protein in a single grande-sized order.
The next frontier: protein soda. Made using the beta-lactoglobulin fraction of whey, protein sodas are being developed by multiple major brands right now — a category that didn’t meaningfully exist a couple of years ago.
“Protein-plus” is the next evolution. Rather than protein alone, formulators are combining it with other functional ingredients — dietary fiber being the most common pairing — to hit two nutrition trends in one product rather than one.
A few well-established ways to actually get more protein without waiting for the soda aisle to catch up: Fairlife Core Power Protein Shakes remain one of the most widely available high-protein ready-to-drink options. Quest Nutrition Protein Bars are a long-standing pick for protein-plus-fiber in one product. For a powder base, Optimum Nutrition Gold Standard Whey is still one of the most reviewed and widely stocked options on the market.
The bottom line: the functional food market this trend sits inside is currently valued at roughly €317 billion globally and is expected to more than double by 2032 — protein isn’t a fad ingredient here, it’s becoming the default expectation across categories that never used to carry it.
