Tuna gets a protein-forward reformulation at Reser's Fine Foods, which has launched a three-SKU High Protein Deli Salads line — including a Tuna Salad delivering 12 grams of protein per serving — now stocked in the deli cases of major grocery retailers nationwide.

The Tuna Salad joins a Chicken Salad (15g per serving) and an Egg Salad (11g per serving) as the seafood entry in what the Beaverton, Ore.-based prepared-foods maker calls a reimagining of classic deli staples. All three products use a cottage-cheese-based dressing that, according to Reser's, delivers 25% more protein and 40–60% fewer calories compared with the company's traditional deli salad line.

The Protein Demand Signal

The launch is backed by a Pollfish survey of 1,000 U.S. consumers aged 16–29, conducted in September 2026, which found that 50% of Gen Z respondents are eating more protein than they were two years ago. Critically for seafood positioning, 95% say they want more variety in their protein sources — and 87% specifically said they would prefer high-protein versions of foods they already know. That data point makes canned- and deli-tuna formats a natural fit: the category already occupies familiar territory in the refrigerated deli set, and a value-added, high-protein positioning gives it a contemporary lift without requiring consumer education on a new species or format.

Megan Torres, senior brand strategy manager for Reser's, noted that shoppers are looking beyond protein shakes and plain chicken breast. "Our chefs used a smoothly blended cottage cheese base to make a creamy dressing," Torres said. "It's an innovative take on classic deli favorites that meets what shoppers are looking for today."

Tuna's Retail Moment

The timing aligns with broader momentum in the value-added tuna segment. Shelf-stable canned tuna has faced years of volume pressure from younger consumers who perceive it as dated, while refrigerated, ready-to-eat formats — pouched tuna, tuna dips, protein-forward tuna salads — have gained shelf space by meeting convenience and clean-label demands simultaneously. Reser's entry into the refrigerated high-protein deli set signals that the format is maturing enough to attract large, multi-category prepared-foods manufacturers, not just specialty seafood brands.

For the broader seafood retail and grocery channel, the Reser's move underscores a familiar pattern: seafood proteins gain mainstream deli penetration when they are bundled with a clear wellness claim. Tuna's naturally high protein density — roughly 20–22 grams per 3-ounce serving in raw form — makes it an efficient base for the category, even after the dressing is factored in. Operators and retail buyers sourcing product for prepared-foods programs may find the format increasingly relevant as value-added seafood competes directly with chicken and egg for deli real estate.

Reser's operates 14 facilities across the U.S. and Mexico and employs more than 5,000 people. The High Protein Deli Salads line is available now.
